Resumo
O presente trabalho consiste no estudo filogenético e na revisão taxonômica
de Prescottia Lindl. (Orchidaceae: Orchidoideae), gênero de orquídea terrestre de
distribuição neotropical. O gênero apresenta ampla distribuição com espécies
ocorrendo da Flórida (E.U.A) à Argentina, sendo que o Brasil concentra a maior
riqueza de espécies. As espécies são caracterizadas por apresentarem flores
esverdeadas a esbranquiçadas, labelo cuculado, superfície estigmática inteira e
quatro polínias. Este estudo corresponde à primeira revisão taxonômica do gênero e
teve como base a coleta de material em campo, assim como a observação de suas
populações in situ e de indivíduos em cultivo, análise de coleções de herbários e
análises filogenéticas. Os estudos filogenéticos foram realizados através de análises
individuais e combinadas de dados de sequências de quatro regiões - três do
genoma plastidial (trnL intron, trnL-F spacer e rpoB-trnC spacer) e uma do genoma
nuclear (ITS). Foram usados os métodos de máxima parcimônia e análise
Bayesiana. Prescottia foi reconhecido como um gênero monofilético, sendo
Galeoglossum A. Rich. & Galeotti seu grupo-irmão. Dentro de Prescottia dois grupos
são formados: um consiste de espécies com folhas longo-pecioladas e o outro é
formado pelo resto das espécies amostradas, incluindo espécies com pecíolo curto,
pseudopecioladas e sésseis. As espécies com flores esbranquiçadas com interior do
labelo piloso formam um grupo monofilético, enquanto que as espécies com flores
esverdeadas formam um grupo parafilético. A segunda parte deste estudo teve
como principal objetivo revisar taxonomicamente o gênero Prescottia, no intuito de
entender a circunscrição das espécies e sua distribuição geográfica, além de
reconhecer caracteres morfológicos que as distingam, bem como resolver questões
nomenclaturais. Quinze espécies são aceitas neste trabalho para Prescottia, sendo
que dois complexos de espécie são indicados. Duas novas espécies (Prescottia
mucugensis C.O. Azevedo & Van den Berg e P. ecuadorensis C.O. Azevedo & Van
den Berg) são descritas. Duas propostas de conservação de nomes foram
elaboradas. Uma nova ocorrência (Prescottia ostenii Pabst) foi citada para o Brasil, e
Prescottia glazioviana Cogn. foi encontrada em Minas Gerais. São propostas 23
lectotipificações, uma neotipificação e 11 novas sinonimizações. Uma espécie foi
reestabelecida e quatro nomina nuda foram detectados. São fornecidos dados
macro e micro-morfológicos, descrições, chave para identificação, ilustrações,
mapas de distribuição e comentários ecológicos para todas as espécies.
Abstract
The present work is a phylogenetic study and a taxonomic revision of
Prescottia Lindl. (Orchidaceae: Orchidoideae), a terrestrial orchid genus with
neotropical distribution. The genus presents a widespread distribution, whose
species occur from Florida (U.S.A) to Argentina. Brazil is the country with major
species richness. The species are characterized by its greenish to whitish flowers,
cucullate lip, stigmatic surface entire, and four pollinia. This study is the first
taxonomic monograph for the genus and is based on fieldwork collection, as well as
observation of in situ populations and individuals in cultivation, study of herbaria
collections, and phylogenetic analyses. The phylogenetic studies were carried out by
individual and combined analyses based on sequences of four DNA regions, three
plastid (trnL intron and trnL-F spacer and rpoB-trnC spacer) and one nuclear (ITS),
using maximum parsimony and Bayesian analyses. Prescottia was recognized as a
monophyletic genus, and Galeoglossum A. Rich. & Galeotti is its sister-group. Within
Prescottia two groups are recovered, one consisting of long petiolate-leaved species
and the other formed by the remainders sampled species, including short petiolateleaved, pseudopetiolate and sessile-leaved species. The species group with whitish
flower and lip inner surface pilose is monophyletic, whereas the greenish flower
species, without inner surface pilose, are paraphyletic. The main objective of the
second part of this study was to present a taxonomic revision of Prescottia, trying to
understand the species circumscription, their geographic distribution, to recognize
distinctive morphologic characters, and also to solve nomenclatural questions.
Fifteen species are accepted for Prescottia in this study, and two species complexes
are indicated. Two new species, Prescottia mucugensis C.O. Azevedo & Van den
Berg and P. ecuadorensis C.O. Azevedo & Van den Berg are described. Two
proposals of name conservation were elaborated. One new record (Prescottia ostenii
Pabst) was cited to Brazil, and Prescottia glazioviana Cogn. was found in Minas
Gerais State. Twenty three lectotypifications, one neotipification, and 11 new
synonymies are proposed. One species was reestablished and four nomina nuda
were detected. Macro and micro-morphological data are given, descriptions,
identification key, illustrations, distribution maps, nomenclatural analysis and
ecological comments for each species are presented.

INTRODUÇÃO GERAL
24
Introdução Geral
A família Orchidaceae inclui cerca de 20.000 espécies e 850 gêneros, sendo
uma das maiores famílias de plantas (Atwood 1986; Dressler 1993). Apresenta
ampla distribuição geográfica, com grande diversidade nos trópicos. A família
pertence à Ordem Asparagales e, filogeneticamente, aparece como grupo-irmão das
demais famílias da ordem (Fay et al. 2000; Judd et al. 2007). Orchidaceae está
rapidamente se tornando uma das mais estudadas famílias de angiospermas em
termos de filogenia. Tais estudos têm demonstrado que vários conceitos anteriores
sobre padrões filogenéticos estavam errados, o que tem feito com que muitas das
classificações prévias necessitem de revisão (Chase et al. 2003).
A tribo Cranichideae já esteve enquadrada em diferentes subfamílias de
Orchidaceae como, por exemplo, Neottioideae Lindl. (e.g. Lindley 1840; Bentham
1881; Schlechter 1911, 1926; Garay 1960; Dressler 1974; Rasmussen 1985) e
Spiranthoideae (e.g. Dressler 1979, 1981, 1990, 1993; Szlachetko 1995). Contudo,
recentes estudos filogenéticos, baseados em morfologia e em dados moleculares,
evidenciaram que ela ficaria mais bem posicionada num conceito expandido de
Orchidoideae (Dressler 1986; Dressler & Chase 1995; Kores et al. 1997, 2000, 2001;
Cameron & Chase 1999; Freudenstein & Rasmussen 1999; Freudenstein et al.
2000). A tribo Cranichideae sensu Dressler (1993) abrange cerca de 95 gêneros e
1.140 espécies, sendo predominantemente terrestre e distribuída em todos os
continentes, com exceção da Antártida, mas apresentando maior diversidade nas
regiões tropicais e subtropicais das Américas e Ásia (Dressler 1993). Dentro de
Cranichideae, Dressler (1993) reconheceu seis subtribos, em grande parte de
acordo com o que havia sido previamente proposto por Schlechter (1926), exceto
por apresentar uma nova subtribo, Prescottiinae (Dressler 1990), criada para
acomodar alguns gêneros anteriormente incluídos na subtribo Cranichidinae. Dentre
essas subtribos, Goodyerinae e Spiranthinae são amplamente distribuídas, enquanto
Cranichidinae e Prescottiinae são restritas ao neotrópico e Manniellinae e
Pachyplectroninae são endêmicas da África Tropical e Nova Caledônia,
respectivamente.
A subtribo Prescottiinae sensu Dressler (1993) é composta por 99 espécies,
distribuídas em sete gêneros: Aa Rchb. f., Altensteinia Kunth, Gomphichis Lindl.,
25
Myrosmodes Rchb. f., Porphyrostachys Rchb. f., Prescottia Lindl. e Stenoptera C.
Presl. Com exceção de Prescottia, todos os outros representantes ocorrem,
sobretudo, em altitudes elevadas da Cordilheira dos Andes.
Prescottia apresenta maior diversidade no Brasil, estendendo-se da Flórida
(E.U.A.), através das Índias Ocidentais, até o nordeste da Argentina. O gênero
apresenta caracteres morfológicos bastante variáveis e as espécies são de difícil
delimitação, razão pela qual, aparentemente, muitas espécies novas foram descritas
e caíram, posteriormente, em sinonímia.
Originalmente o gênero foi descrito como “Prescotia”, com um único ‘t’, em
homenagem a “John Prescot” (Lindley in Hooker 1824). Em 1836, Lindley passou a
se referir ao gênero com a grafia Prescottia, com dois “t”, após ter tido conhecimento
de que “John Prescott” se escrevia desta forma. Desde então o gênero vem sendo
tratado por alguns autores da forma original (e.g. Steudel 1841; Vöth 1976; Farr et
al. 1979; Ackerman 1989), enquanto outros adotaram a forma alternativa (e.g.
Cogniaux 1895; Hoehne 1945; Pabst & Dungs 1975; Brummitt & Powell 1992;
Dressler 1993; Greuter et al. 1993; Ackerman 1995, 2003). A espécie tipo do gênero
foi descrita como “Prescotia plantaginifolia”, tendo sido citada desta forma em todo o
protólogo, aparecendo dessa forma, várias vezes no texto e no cabeçalho da
ilustração, sendo que somente na prancha o nome está grafado como “Prescotia
plantaginea”. Após a publicação original, o nome Prescotia plantaginifolia foi adotado
por Loddiges (1824) e Sprengel (1826). Mais tarde o próprio Lindley (1836, 1840)
passou a citar a espécie tipo do gênero como Prescottia plantaginea, embora não
tenha dado nenhuma explicação a respeito da mudança e nem tenha rejeitado o
outro nome. Vöth (1976) propôs o uso de Prescotia plantaginifolia, tendo sido
seguido apenas por Farr et al. (1979), Ackerman (1989, 1995, 2003) e Greuter et al.
(1993), enquanto outros autores (e.g. Cogniaux 1895; Hoehne 1945; Pabst & Dungs
1975) usaram o nome P. plantaginea.
Com o intuito de evitar futuras confusões nomenclaturais a respeito do nome
do gênero e de sua espécie-tipo, Azevedo & Van den Berg (2005) propuseram a
conservação do nome Prescottia (com esta grafia) e do nome Prescottia
plantaginea, rejeitando o epíteto “plantaginifolia”. Ressalte-se que é como P.
plantaginea que a espécie está determinada no material-tipo, no herbário de Lindley.
O Comitê de Nomenclatura para Plantas Vasculares (“Nomenclature Committee for
26
Vascular Plants”), em Brummitt (2007), recomendou a conservação do nome do
gênero como proposto por Azevedo & Van den Berg (2005), embora não tenha
recomendado a conservação de Prescottia plantaginea com a justificativa que,
embora os dois nomes tenham sido publicados simultaneamente (provavelmente por
uma confusão feita por Hooker) e este (P. plantaginea) seja o nome mais usado
hoje, alguns autores usaram P. plantaginifolia. O primeiro a sinonimizar um nome
sob outro foi Steudel (1841), que adotou P. plantaginifolia Lindl. Desta forma,
embora menos conhecido e usado, P. plantaginifolia Lindl. ex Hook. é o nome
correto e, portanto, o que deve ser adotado.
Dificuldades na delimitação e identificação das espécies parecem ser uma
questão histórica no gênero. Não foram poucas as confusões resultantes da
inobservância ou erros relacionados à presença e ausência de tricomas no interior
do labelo. Cogniaux (1895) usou este caráter já nos primeiros passos de sua chave
de identificação, na Flora Brasiliensis. Cogniaux (1895) citou como glabras, por
exemplo, Prescottia densiflora (Brongn.) Lindl., P. micrantha Lindl. e P. microrhiza
Barb. Rodr. que, na verdade, apresentam tricomas no interior do labelo. Hoehne
(1945) comentou sobre este problema, atribuindo a confusão ao fato de que quando
o material de herbário é fervido os tricomas aderem à parede do labelo, dificultando
a sua visualização. Para verificar sua presença deve-se observar o material de
herbário a seco em microscópio estereoscópico.
Outra característica utilizada para a descrição de muitas espécies novas e
hoje relacionadas como sinônimos, foi a variação morfológica das folhas. Suas
formas e dimensões oscilam de acordo com o meio em que a planta cresce e
Hoehne (1945) acreditava, ainda, que a idade da planta também poderia exercer
influência em tais variações.
Apesar de se tratar de um gênero relativamente pequeno, a delimitação das
espécies é muito difícil. Não existem muitos caracteres qualitativos diagnósticos.
Uma grande variabilidade morfológica é observada, especialmente entre populações
de uma mesma espécie. Tal variação entre as populações acarreta dificuldades de
delimitação das espécies a partir de dados macro-morfológicos o que tem sido
responsável também pela identificação incorreta de muitos espécimes em herbário.
O presente trabalho teve como objetivos: (i). revisar taxonomicamente o
gênero Prescottia, com base em dados macro e micromorfológicos, apresentando
27
chave de identificação para as espécies, descrições, ilustrações, comentários e
discussão sobre aspectos morfológicos e taxonômicos, além de dados sobre a
distribuição geográfica das espécies, e (ii). apresentar uma hipótese filogenética
para o mesmo, com base em dados moleculares, para testar o monofiletismo de
Prescottia, e compreender suas relações interespecificas.
28
Histórico taxonômico da subtribo Prescottiinae
Em 1840, Lindley posicionou alguns dos gêneros hoje reconhecidos como
pertencentes à subtribo Prescottiinae (Altensteinia, Gomphichis, Prescottia e
Stenoptera) junto de outros gêneros pouco relacionados a estes, na tribo Neotteae,
divisão Cranichidae. Esta divisão era caracterizada por apresentar flores nãoressupinadas, labelo côncavo, coluna ereta, antera incumbente e rostelo truncado. A
divisão Spiranthidae também foi proposta para acomodar os gêneros com flores
ressupinadas. Bentham (1881) e, subsequentemente, Bentham & Hooker (1883)
modificaram o sistema de tribo e subtribo de Lindley e uniram as orquídeas de flores
ressupinadas e as não-resupinadas em Spirantheae. Esta subtribo foi composta por
Aa, Altensteinia, Gomphichis, Prescottia e Stenoptera junto com outros táxons de
Spiranthinae.
Quase simultaneamente, Reichenbach (1881) descreveu o gênero Manniella,
da África tropical, e hipotetizou sua possível relação com o gênero Stenoptera do
Neotrópico. Com base em caracteres vegetativos, Pfitzer (1887) propôs a subfamília
Neottiinae, que consistia de várias subtribos, dentre as quais a subtribo
Cranichideae, contendo gêneros como Gomphichis, Prescottia, Altensteinia
(incluindo Aa e Myrosmodes) e Stenoptera, e a subtribo Spirantheae consistindo de
nove gêneros.
Schlechter (1915) juntou Aa (incluindo Myrosmodes), Altensteinia,
Porphyrostachys, Prescottia e Stenoptera (incluindo Gomphichis) com Cranichis,
Pterichis Lindl. e Fuertesiella, sob o mesmo grupo, denominado Cranichidinae. Cinco
anos mais tarde, Schlechter (1920) publicou uma síntese das Spiranthinae, na qual a
subtribo Cranichidinae diferia da subtribo Spiranthinae pela posição do labelo, sendo
as flores ressupinadas na última. Schlechter (1926) refinou e expandiu o sistema de
classificação previamente proposto por ele próprio, incluindo uma chave de
identificação para a subtribo. Nesse novo cenário, através de uma chave dicotômica,
Cranichideae foi subdividida em dois grupos principais: ”obtusirostellata” e
“productirostellata”, baseados na forma do rostelo. No primeiro, Aa, Altensteinia,
Gomphichis, Porphyrostachys e Stenoptera foram colocados junto de
Wullschlaegelia Rchb. f. (atualmente considerado como membro da subfamília
Epidendroideae). Um ano mais tarde Schlechter (1927) incluiu em Cranichidinae:
Wullschlaegelia, Pseudocentrum Lindl., Solenocentrum Schltr., Porphyrostachys,
29
Altensteinia, Aa (= Myrosmodes), Prescottia, Stenoptera (= Gomphichis.), Pterichis
(= Acraea Lindl.), Fuerstesiella Schltr., Cranichis Sw. (= Ocampoa A. Rich. & Gal.) e
Ponthieva R. Br. (= Nerissa Raf., = Schoenleinia Kl., = Calorchis Barb. Rodr.).
Em Cranichidinae, Dressler (1981; 1990) reconheceu 15 gêneros em duas
alianças: a aliança Altensteinia, caracterizada por coluna truncada, polínia
granulosa, ausência de caudículo e labelo simples livre da coluna, incluindo Aa,
Altensteinia, Gomphichis, Myrosmodes, Porphyrostachys, Prescottia e Stenoptera; e
a aliança Cranichis, incorporando gêneros com coluna pontiaguda, polínia
cartilaginosa com caudículos e labelo geralmente fundido com a coluna. Essas
alianças seguiram essencialmente a divisão de Schlechter (1926).
Na revisão de Spiranthinae, Garay (1982) reconheceu 390 espécies em 44
gêneros. Nesta revisão o autor propôs o gênero monotípico Pseudocranichis para
acomodar Cranichis thysanochila B.L. Rob. & Greenm. Esta espécie foi inicialmente
descrita em Cranichis principalmente por suas flores não-ressupinadas. BurnsBalogh (1986) atribuiu Pseudocranichis a Cranichidinae em vez de Spiranthinae
baseada nas seguintes características presentes em Pseudocranichis: deiscência
das anteras lateral, polínia circular em corte transversal e flores não-ressupinadas.
Rasmussen (1985), em seu tratamento para as Orchidaceae, posicionou
Prescottia e gêneros aparentados em Spiranthinae. Este grupo foi incluído na tribo
Neottieae, subfamília Neottioideae. As Spiranthinae, para Rasmussen, eram
definidas por apresentarem folhas basais em roseta e por seus órgãos
armazenadores (raízes) espessos e agregados. Este grupo, como definido por
Rasmussen (1985), pode ser comparado com a tribo Cranichideae de Dressler
(1990).
Burns-Balogh & Funk (1986) caracterizaram a subtribo Cranichidinae por
apresentar flores não-ressupinadas, estipe hamular e polínia redonda em corte
transversal. Os autores incorporaram a esta 15 gêneros e cerca de 200 espécies,
incluindo os gêneros de Prescottiinae como membros de uma Cranichidinae
expandida. Estes autores, em acordo com a classificação de Schlechter (1926),
reconheceram também as subtribos monotípicas Manniellinae e Pachyplectroninae
dentro da tribo Cranichideae.
Prescottiinae foi formalmente proposta como uma subtribo de Cranichideae
por Dressler (1990) para acomodar as orquídeas terrestres de flores não-
30
ressupinadas dos Neotrópicos. Essa nova subtribo incluiu Aa, Altensteinia,
Myrosmodes, Porphyrostachys, Prescottia e Stenoptera. A relação de grupo irmão
entre Prescottiinae e Spiranthinae foi sugerida por Dressler (1990). As Prescottiinae
assemelham-se às Spiranthinae em seu tipo de velame, no formato de suas polínias
e nos lobos retrorsos típicos de Spiranthinae que estão presentes em Prescottia
(Dressler 1993). A mesma circunscrição da subtribo foi adotada por Dressler (1993)
em seu sistema de classificação posterior, o qual dividiu a subfamília Spiranthoideae
em três tribos: Diceratosteleae, Tropidieae e Cranichideae. Neste sistema a tribo
Cranichideae foi a maior desta subfamília, com 95 gêneros e cerca de 1.140
espécies, incluindo seis subtribos: Spiranthinae, Prescottiinae, Cranichidinae,
Goodyerinae, Manniellinae e Pachyplectroninae. As orquídeas terrestres da América
tropical que habitam áreas de altitudes elevadas foram incluídas em Prescottinae,
mais rica nos Andes, onde são encontrados mais de dois-terços das espécies. A
subtribo, como definida por Dressler (1990), é unida pelo velame do tipo Spiranthes,
flores não-ressupinadas, rostelo laminar e polínias granulosas, sem hâmulo. As
Prescottiinae incluem aproximadamente 100 espécies em sete gêneros: Aa Rchb. f.,
Altensteinia Kunth, Gomphichis, Myrosmodes Rchb. f., Porphyrostachys Rchb. f.,
Prescottia Lindl. e Stenoptera C. Presl (Dressler 1990, 1993).
Szlachetko (1995) propôs incluir o morfologicamente distinto gênero
Pseudocranichis em Prescottiinae. Nesta classificação, Szlachetko (1995)
reconheceu a tribo Spirantheae como um grupo monofilético contendo seis
subtribos, dentre as quais Prescottiinae, que incluiu Aa, Altensteinia, Myrosmodes,
Porphyrostachys, Prescottia, Pseudocranichis e Stenoptera. O autor supôs uma
relação próxima entre Prescottiinae e Spiranthinae. González-Tamayo (1996)
discutiu o inapropriado posicionamento de muitos táxons não-ressupinados no
gênero Cranichis. Sugerindo a inclusão de Pterichis, Nothostele e Fuertesiella em
Prescottiinae, ao invés de Cranichidinae, com base na adnação das pétalas à sépala
dorsal.
Numa abordagem cladística de Cranichideae e Prescottiinae, usando dados
morfológicos, Vargas (1997) chegou à conclusão de que Prescottiinae era um grupo
monofilético, concordando com a circunscrição dos sistemas de classificação de
Dressler (1990; 1993) e Szlachetko (1995), mas sua relação de grupo-irmão com
Spiranthinae foi fracamente sustentada. Além disso, segundo Vargas (1997), o
31
gênero africano Manniella e Prescottiinae foram considerados grupos-irmãos por
apresentarem labelo livre da coluna, apesar da distinta distribuição geográfica.
O trabalho de Salazar et al. (2003) foi o primeiro estudo de filogenia molecular
para a tribo Cranichideae. Neste, Prescottiinae apareceu como um grupo com dois
clados, um predominantemente de gêneros andinos (Stenoptera, Gomphichis,
Porphyrostachys e Aa) e o outro formado somente pelo gênero Prescottia, com P.
tubulosa como grupo-irmão de P. plantaginifolia-P. aff. oligantha. Desta forma,
Salazar et al. (2003) concluíram que Prescottiinae e Prescottia não são grupos
monofiléticos. No trabalho de Salazar et al. (2003), a amostragem de Prescottiinae
foi incompleta (nem todos os gêneros foram amostrados), e o relacionamento entre
Prescottiinae, Cranichidinae e Spiranthinae não ficou claramente determinado,
especialmente o posicionamento do gênero Prescottia.
Chase (2003) não reconheceram a subtribo Prescottiinae, uma vez que
Prescottiinae como definida por Dressler (1993), foi considerada parafilética por
Salazar et al. (2003). Chase (2003) preferiu juntar as duas subtribos sob o nome
mais antigo, Cranichidinae sensu Dressler (1981). Salazar et al. (2003) sugeriram a
necessidade de trabalhos com maior número de caracteres e espécies para
esclarecer a relação filogenética de Prescottia e Prescottiinae entre si, e entre eles e
as subtribos Cranichidinae e Spiranthinae.
Alvarez (2005), com estudos de filogenia molecular para a subtribo
Prescottiinae, concluiu que (i) Prescottiinae é polifilética; (ii) ambos os clados de
Prescottiinae apresentam maior afinidade com Spiranthinae do que com
Cranichidinae, como sugerido por Dressler (1990; 1993) e Szlachetko (1995); e (iii)
Prescottia apresentou-se parafilética, pois Pseudocranichis, que não tinha sido
incluído na análise de Salazar et al. (2003), apareceu aninhado dentro deste. Estes
resultados indicaram que nenhum dos sistemas de classificação correntes ou
prévios para estes táxons está correto, visto que a delimitação de Dressler (1990;
1993) de Prescottiinae não é monofilética; a delimitação expandida de Prescottiinae
proposta por Szlachetko (1995) é parafilética; e a classificação revisada de Chase
(2003), que inclui Prescottiinae em Cranichidinae, seguindo Dressler (1981), torna a
última polifilética. Além disso, Prescottia só pode ser considerado monofilético se
incluir Pseudocranichis ou excluir Prescottia tubulosa.
32
Figueroa et al. (2008), seguido de Álvarez-Molina & Cameron (2009) e
Salazar et al. (2009), com base em dados moleculares, comfirmaram o parafiletismo
de Prescottia s.s., confirmando a relação de Pseudocranichis thysanochila com
Prescottia tubulosa. Salazar et al. (2003) já haviam resaltado a similaridades entre a
coluna e o labelo de Pseudocranichis thysanochila e Prescottia tubulosa. Com base
em dados moleculares e morfológicos Salazar (2009) transferiu P. tubulosa and P.
thysanochila para o gênero Galeoglossum A. Rich. & Galeotti (Salazar 2009).
Histórico taxonômico do gênero Prescottia
O gênero Prescottia foi descrito por Lindley (in Hooker 1824) com base em
uma única espécie brasileira, Prescottia plantaginifolia. O gênero foi caracterizado
por apresentar flores não-ressupinadas, sépalas e pétalas revolutas, sépalas laterais
conadas na base, labelo ereto, carnoso, cuculado, inteiro, coluna diminuta envolvida
pelo labelo, antera biloculada, persistente, estigma paralelo e polínias 4 (em dois
pares), granulosas. Posteriormente, duas espécies descritas originalmente em
Cranichis [C. stachyodes Sw. e C. oligantha Sw. (Swartz 1788)], foram transferidas
para Prescottia por Lindley (1836; 1840).
Barbosa-Rodrigues (1877, 1881) descreveu dez espécies novas de Prescottia
para o Brasil. Cogniaux (1895), na Flora Brasiliensis, citou 18 espécies de Prescottia
para o Brasil. Nesta obra o autor descreveu as espécies brasileiras e apresentou
uma chave de identificação para as mesmas. Cogniaux (1895) não mencionou as
outras espécies de Prescottia, não brasileiras, descritas anteriormente (P.
ophioglossoides Spreng., P. petiolaris Lindl., P. oligantha (Sw.) Lindl., P. tenuis
Lindl., P. lanceaefolia Link & Otto ex Steud., P. pachyrhiza A. Rich. & Galeotti, P.
orchioides Lindl., P. lindeniana A. Rich. & Galeotti, P. galeottii Rchb. f., P. cordifolia
Rchb. f., P. pellucida Lindl. e P. myosurus Rchb. f. ex Griseb.), embora tenha
sinonimizado as espécies brasileiras Prescottia colorans Lindl. e P. longipetiolata
Barb. Rodr. sob P. stachyodes (Sw.) Lindl., da Jamaica.
Na Flora Brasilica, Hoehne (1945) citou 17 espécies para o Brasil, além de
incluir algumas espécies exóticas que o autor acreditava poderem ocorrer no Brasil
(Prescottia longifolia Schltr., P. smithii Schltr., P. panamensis Schltr., P. filiformis
Schltr. e P. gracilis Schltr.). Também criou um nomen novum para a espécie
equatoriana Prescottia longipetiolata Schltr.: Prescottia schlechteri Hoehne.
33
Entretanto, não mencionou nada sobre as variedades nem sobre Prescottia tubulosa
(Lindl.) L.O. Williams e não fez nenhum comentário sobre as espécies descritas
antes dos trabalhos de Cogniaux, com exceção de Prescottia lanceaefolia Link &
Otto ex Steud., a qual considerou como sinônimo de P. lancifolia Lindl.
Em 1975, Pabst & Dungs citaram 17 espécies para o Brasil e estabeleceram
quatro grupos informais para as espécies brasileiras do gênero, baseados na forma
da folha e na presença ou ausência de tricomas no interior do labelo. Ackerman
(2003), em Genera Orchidacearum, citou 24 espécies para o gênero, apresentando
uma descrição genérica, dados sobre distribuição, palinologia, ecologia e
polinização.

Abstract
Prescottia is a Neotropical genus with its main diversity center in Brazil. It
comprises approximately 15 species of mostly terrestrial herbs that are easily
recognizable by their non-resupinate tiny flowers with cucullate labellum. The
present study presents phylogenetic analyses among Prescottia speciesusing
sequences of three plastid (trnL intron and trnL-F spacer and rpoB-trnC spacer) and
one nuclear (ITS) regions. Matrices were analyzed individually and in a combined
analysis using maximum parsimony and Bayesian approaches. All analyses were
congruent in supporting the monophyly of Prescottia and Galeoglossum as sistergroup. Within Prescottia the species relationships are well resolved in two well
supported main clades, one including the long petiolate-leaved species and the
other grouping the remainder sampled species. The species with whitish flowers
and lip with pilose inner surface form a monophyletic group nested within a
paraphyletic group of the species with greenish flowers and lip with glabrous inner
surface. Two species complexes are indicated. The infrageneric classification
previously proposed for Prescottia is not supported by this study.
Keywords – Bayesian inference, molecular systematics, parsimony, plastid DNA,
nuclear DNA.

Introduction
Orchidaceae are rapidly becoming one of the best-studied angiosperm
families in terms of infra-familial phylogenetic relationships. These studies
demonstrate that several previous concepts about phylogenetic patterns were
incorrect, which make all previous classifications in need of review (Chase et al.
2003).
Prescottiinae s.s. was formally proposed as a subtribe within Cranichideae by
Dressler (1990) to accommodate the non-resupinate, terrestrial species of the
Neotropics, included at that subtribe before. The subtribe comprises about 100
species included in seven genera: Aa Rchb.f., Altensteinia Kunth, Gomphichis Lindl.,
Myrosmodes Rchb.f., Porphyrostachys Rchb.f., Prescottia Lindl., and Stenoptera
C.Presl. (Dressler 1990, 1993). The subtribe, as defined by Dressler (1990), is united
by the Spiranthes-type of velamen, non-resupinate flowers, a laminar rostellum, and
soft-pollinia lacking a hamulus. The subtribe is most abundant in Andean South
America, where over two-thirds of the species are found.
A sister relationship between Prescottiinae and Spiranthinae was suggested
by Dressler (1990, 1993) based on the velamen and pollinia types, and retrorse
lobules, typical of the Spiranthinae and also present in Prescottia (Dressler 1993).
Szlachetko (1995) proposed including the morphologically distinctive genus
Pseudocranichis Garay in Prescottiinae. In his classification of Orchidales, he
recognized tribe Spirantheae as a monophyletic group containing six subtribes. One
of them was Prescottiinae, which included Aa, Altensteinia, Myrosmodes,
Porphyrostachys, Prescottia, Pseudocranichis, and Stenoptera. Similarly to Dressler
(1990, 1993) Szlachetko (1995) hypothesized a close relationship between
Prescottiinae and Spiranthinae.
Using cladistic methods in a morphology-based analysis of Cranichideae and
Prescottiinae, Vargas (1997) recovered a monophyletic Prescottiinae, supporting
Dressler’s (1990; 1993) and Szlachetko’s (1995) circumscription of the subtribe, but
its sister relationship to the Spiranthinae was only weakly supported by the data. In
addition, the African genus Manniella Rchb.f. and the Neotropical Prescottiinae were
found to be sister to each other on the basis of possessing the lip free from the
column, despite their distinctive distributions.
46
Vargas (1997), based on the morphological resemblance between Prescottia
tubulosa (Lindl.) L.O. Williams and species of Porphyrostachys, suggested the former
should be transferred to the latter. Recent molecular studies (Salazar et al. 2003,
2009; Álvarez 2005; Álvarez-Molina & Cameron 2009) showed that the
morphological similarities found in Prescottia tubulosa and Porphyrostachys are
probably the result of convergence.
In contrast, molecular studies based on nuclear and chloroplast DNA regions
for Cranichideae (Salazar et al. 2003) have recovered a paraphyletic Prescottiinae,
divided into two lineages, the first being Prescottia and a monophyletic group
comprising the remaining sampled genera of the subtribe (Aa, Gomphichis,
Porphyrostachys, and Stenoptera).
Salazar et al. (2003) pointed out the similarities between the column and
labellum of Pseudocranichis thysanochila (B.L.Rob. & Greenm.) Garay and the
Mexican Prescottia tubulosa. Molecular studies (Figueroa et al. 2008, Álvarez-Molina
& Cameron 2009, Salazar et al. 2009) found the former is sister to Prescottia
tubulosa, confirming in part Szlachetko’s (1995) hypothesis of their affinities, and
Salazar et al. (2003) suggestion.
Most recently, Chase et al. (2003) proposed a new classification of the
Orchidaceae based on phylogenetic patterns. In this system, subtribe Prescottiinae
was not recognized, being included in an expanded concept of Cranichideae (sensu
Dressler 1981). This decision was mainly based on molecular studies in
Cranichideae (Salazar et al. 2003), in which the Prescottiinae were shown to be
paraphyletic. This classification has been adopted in the series Genera
Orchidacearum (Pridgeon et al. 2003).
Alvarez (2005) concluded that Prescottiinae are polyphyletic, and that both
clades of Prescottiinae showed an affinity to Spiranthinae, rather than Cranichidinae
as suggested by Dressler (1990; 1993) and Szlachetko (1995). The relationships
among Prescottiinae, Cranichidinae and Spiranthinae were not clearly resolved (e.g.
Salazar et al. 2003; Álvarez-Molina & Cameron 2009), especially the placement of
Prescottia.
Prescottia s.s. was found to be paraphyletic (Figueroa et al. 2008, ÁlvarezMolina & Cameron 2009; Salazar et al. 2009) because Pseudocranichis is nested
within it. Prescottia is monophyletic only if Pseudocranichis is classified within it or
47
Prescottia tubulosa is removed from it. To make Prescottia monophyletic, Salazar et
al. (2009) argued for the removal of P. tubulosa from Prescottia, and transferred it
and Pseudocranichis thysanochila to Galeoglossum A.Rich. & Galeotti (Salazar
2009). Morphologically, the main difference between Galeoglossum and Prescottia
are the distal part of the lip, that is open, with a distinct apical lobule in the former,
and not cucullate as in Prescottia. The stigma saddle-shaped, separated by a nonreceptive central portion, that is present in Galeoglossum, whereas in Prescottia s.s.
there is a single receptive area located on the ventral surface of the column. The
other difference is the pollinarium, which has two ribbon-like pollinia in Galeoglossum
(Salazar 2009), while in Prescottia there are four obovate pollinia.
Pabst & Dungs (1975) established four informal groups within Prescottia.
Prescottia colorans “alliance” including: P. glazioviana Cogn., P. leptostachya Lindl.,
P. stachyodes Lindl., and P. stricta Schltr., characterized by the lip internally
glabrous, and elliptic leaves, clearly petiolate. Prescottia plantaginea “alliance”
including: P. montana Barb.Rodr., P. nivalis Barb.Rodr., P. phleoides Lindl., and P.
plantaginifolia Lindl. ex Hook., distinguished by the lip internally glabrous, and
lanceolate leaves indistinctly petiolate. Prescottia oligantha “alliance” was
represented by P. densiflora Lindl., P. microrhiza Barb.Rodr. P. oligantha (Sw.)
Lindl., and P. pubescens Barb.Rodr., differentiated by the lip internally densely
pilose, and elliptic or oval leaves.The last, Prescottia lancifolia “alliance” comprised
by P. epiphyta Barb.Rodr., P. lancifolia Lindl., P. octopollinica Barb.Rodr., and P.
polyphylla Porsch., separated from the others by the lip internally densely pilose, and
lanceolate leaves.
The study presented here attempts to evaluate the monophyly of the genus
Prescottia in its current circumscription, to check the monophyly of the proposed
infrageneric alliances, to investigate phylogenetic relationships within and among
species of Prescottia, and to explore evolutionary patterns within the genus using
sequence data from the plastid (trnL intron and trnL-F spacer and rpoB-trnC spacer)
and nuclear (ITS) genome.

Materials and Methods
Taxon sampling - In order to reconstruct a phylogeny for the genus we
included 11 of 15 species of Prescottia accepted in a recent taxonomic revision
(Chapter 3). Besides the accessions of Prescottia, one species of each genera of
Cranichidinae s.s. and Prescottiinae s.s. (Galeoglossum, Stenoptera, Altensteinia,
Porphyrostachys, Gomphichis, Aa, Pterichis Lindl., Cranichis Sw., Ponthieva R.Br.),
and a couple of Spiranthinae were included in the ingroup (Appendix 1). Galeottiella
sarcoglossa (A.Rich. & Galeotti) Schltr. (Galeottiellinae) was taken as outgroup,
based on previously molecular studies in Cranichideae (Salazar et al. 2003, 2009;
Álvarez-Molina & Cameron 2009). Twenty five percent of the sequences were
obtained from Genbank, and the remaining 75% were sequenced in this study.
Prescottia carnosa C.Schweinf., P. glazioviana, P. lojana Dodson and P.
ecuadorensis C.O. Azevedo & Van den Berg were not included due to lack of
suitable material for molecular work. Besides, we included different morphs or
several samples from different locations of Prescottia leptostachya, P. montana, P.
oligantha, P. plantaginifolia, P. spiranthophylla Barb. Rodr., and P. stachyodes, in
order to assess the existence of sequence polymorphism below the species level.
Several protocols for herbarium material were tried without sucess. Appendix 1 lists
all species sampled in this study with voucher information and Genbank accession
numbers.
DNA extraction, amplification, and sequencing - Total DNA was extracted
mostly from fresh or silica-gel-dried leaves using a modified version of the 2× CTAB
protocol (Doyle & Doyle 1987). For amplification and sequencing of nuclear Internal
Transcribed Spacers (ITS) we used the primers 75 and 92 (Desfeaux et al. 1996),
and a PCR program consisting of 40 cycles of 94ºC denaturation for 1 min, 50ºC
annealing for 1 min, and 72ºC extension for 3 min, with 72ºC for 7 min of final
extension. To reduce problems related to secondary structure during amplification
and sequencing, 2% dimethyl sulfoxide (DMSO) and 1.0 M of betaine were added to
the PCR. For the trnL intron and trnL-F spacer (hereafter trnL-F) we used the four
universal primers (c, d, e, and f) of Taberlet et al. (1991) and a PCR program
consisting of 35 cycles of 94ºC denaturation for 45 s, 50-55ºC annealing for 1 min,
49
and 72ºC extention for 1:30 min, with 72ºC for 10 min of final extension. The plastid
spacer rpoB-trnC (Shaw et al. 2005) was amplified consisting of 30 cycles of 94ºC
denaturation for 30 s, 50ºC annealing for 30 s, and 72ºC extention for 1 min, with
72ºC for 7 min of final extension (See table 1 to the PCR programs used for each
DNA regions).
Amplification of all DNA regions was carried out in 50 µL polymerase chain
reactions (PCR) including 1.25 units of Taq polymerase (Phoneutria LTDA, Belo
Horizonte, Brazil), 1 × Mg-free DNA polymerase buffer (Phoneutria), 2.5 mM MgCl2,
10 mM dNTP, 0.05% bovine serum albumin (BSA), 0.5 µM each primer.
All the PCR reactions were performed in a GeneAmp PCR System 9700
termocycler (Applied Biosystems). PCR products were quantified and then purified
with Exonuclease I and Shrimp alkaline phosphatase – SAP (kit ExoSapIT, GE
Healthcare). Which were sequenced in both directions, using the Big Dye Terminator
kit version 3.1 (Applied Biosystems) on a SpectruMedix SCE9624 automated
capillary sequencer following the manufacturers’ protocols. The primers used for
sequencing were the same as those used for PCR.
Sequence alignment and indel coding - Electropherograms were edited and
assembled using STADEN PACKAGE (Staden et al. 1998). Sequence fragments
were subjected to BLAST searches to verify their identity. The sequences were
aligned using Clustal X, version 1.8 (Thompson et al. 1997) and subsequently
visually adjusted as necessary, following the guidelines in Kelchner (2000).
The indels were coded and included as a separate binary (presence/absence
of the gap, assuming that state 0 denotes absence of a gap) for each DNA regions
using GapCoder software (Young & Healy 2003). All autopomorphic sites were
manually removed. The trnL-F coded indels were removed because its RI was lower
than the trnL-F without coded indels. The aligned matrix is available on request from
COA and CVDB, and all sequences have been submitted to GenBank
(http://www.ncbi.nlm.nih.gov) (see Appendix 1).
Phylogenetic analyses – The incongruence length difference (ILD) test
(Farris et al. 1995) was performed to assess the congruence between data partitions,
to verify the possibility to combine different phylogenies of the same taxa from
different genes (Dolphin 2000). The data partitions were combined in the following
50
way: trnL-trnF × rpoB-trnC and then plastid regions × ITS. The ILD test was
performed with PAUP* (Phylogenetic analysis using parsimony, version 4.0b 10
(Swofford 2002), as the partition homogeneity test (PHT). For each partition, we used
500 replicates for ILD, and in each replicate heuristic searches with 50 replicates of
random taxon addition, tree bisection-reconnection (TBR) branch swapping
algorithm, saving 15 trees per replicate.
Maximum parsimony (MP) - Analyses were conducted in PAUP* with Fitch
parsimony (equal weights, unordered characters; Fitch 1971) as the optimality
criterion. Each data set was analyzed separately, and then we preformed an analysis
with all plastid regions (cpDNA), after that a combined analysis with all data sets
(cpDNA e nrDNA) were. Each search consisted of 2,000 random taxon-addition
replicates, with tree bisection-reconnection (TBR) branch swapping and the
MULTREES option on, saving all most parsimonious trees. All characters were
unordered and equally weighted (Fitch parsimony; Fitch 1971). Internal support of
clades was evaluated by the bootstrap (Felsenstein 1985), with 5,000 replicates with
tree bisection-reconnection (TBR) branch swapping, saving 20 trees per replicate.
Bayesian analyses (BA) - The models of sequence evolution were chosen
using the hierarchical likelihood ratio test conducted in MRMODELTEST version 2.2
(Nylander 2004). The analysis was run at MRBAYES version 3.1 (Ronquist et al.
2005). Two completely independent analyses starting from different randomly chosen
trees, of four Markov chains were run simultaneously for 2,000,000 generations,
sampling from the trees every 100th generation. The average standard deviation of
split frequencies was reached at around 1,000,000 generation. Therefore, the trees
produced in the first 1,000,000 generations (10,000 trees) were discarded as an
extended ‘‘burn-in,’’ and inference about relationships was based only on the
remaining 1,000,000 generations (10,000 trees).
Results
Details on the sizes of the aligned matrices, number of characters considered
in the analysis, number of variable sites, number of potentially informative sites for
the parsimony, number of changes per site, length (number of steps) of the trees
obtained, consistency index (CI), retention index (RI), transition / transversion rates,
51
trees generated in the heuristic search, and number of taxa used in each region
analyzed are provided in Table 2. In all parsimony analyses, we selected the first tree
obtained as a random sample for displaying the results, plotting the support values
on it. Clades that were not present in all shortest trees are marked with an
arrowhead; clades without values have less than 50% bootstrap.
Parsimony analyses – The most variable data set was ITS (32% variable
characters), which also had the lowest consistency index (CI = 0.63 and RI = 0.81;
characters optimized on the combined tree). The rpoB-trnC variation was around
15%, with a CI = 0.73, and RI = 0.83. The least variable data set was trnL-F region
with only 12% potentially informative sites, with a CI = 0.69, and the lowest retention
indice, RI = 0.72.
The analysis of ITS included 684 characters, from which 32% were variable
and 16% were parsimony informative (Table 2). Maximum parsimony analysis of this
data generated 144 equally parsimonious trees, with 725 steps, one of which is
shown in Fig. 1. In this data set, Prescottia oligantha (Azevedo 333) and P.
stachyodes (Azevedo 325, and Pangui) were removed because we were unable to
obtain good quality sequences of them. The ITS analysis strongly support the
monophyly of Prescottia (BP 99). The relationship of the group with Galeoglossum
tubulosum (Lindl.) Salazar & Soto Arenas and G. thysanochilum (B.L.Rob &
Greenm.) Salazar as sister-group to Prescottia is not confirmed in this analysis.
Instead, Spiranthinae are sister to a group with low support (BP 68), unresolved,
comprising the Altensteinia clade, Prescottia, Galeoglossum, and Cranichidinae s.s.
Within Prescottia two main clades were recovered; one including the long petiolateleaved species (clade A, with BP 100), and the other clade presenting the remainder
species. In the former, Prescottia stachyodes samples are sister to P. montana
samples. Within the other clade, two other subclades are present. One, clade B,
includes P. leptostachya samples sister to P. mucugensis C.O. Azevedo & Van den
Berg. and P. phleoides (BP 100). The other clade presents two subclades: one with
the species with sessile to pseudopetiolate leaves (clade C) and the other with all
species with whitish flowers, and lip inner surface pilose (clade D). Clade C is a well
supported group (BP 99), and includes P. plantaginifolia samples sister to P.
spiranthophylla samples. Clade D is also well supported (BP 98), including P.
52
lancifolia sister to P. ostenii Pabst (BP 82), which in turn is sister to P. densiflora and
P. oligantha samples (BP 87).
The trnL-F analysis included 1.388 characters, from which 12% were variable
and parsimony informative (Table 2). Here, sequences of P. lancifolia (Bocayuva
198), P. leptostachya (Azevedo 201, and 250) and P. stachyodes (Azevedo 200,
277, 277.1, s.n., 318, 325, van den Berg s.n., Salazar 7312, EC, Pan) were removed
because we could not obtain sequences of good quality. The heuristic search based
on the trnL-F data set generated 1.014 equally parsimonious trees of 602 steps, one
of which is shown in Fig. 2. The intergeneric relationships are similar to those
recovered by ITS. The Spiranthinae are sister to a polytomy comprising the
Altensteinia clade, Prescottia, Galeoglossum, and Cranichidinae s.s. However, the
monophyly of Prescottia was not corroborated in this analysis. Galeoglossum
tubulosum and G. thysanochilum are embedded in Prescottia with low support (BP
52). Besides that, this analysis presents the same groups defined in the ITS tree as
clade A (BP 100) and B (BP 99). The clades C and D found in the ITS tree are not
formed with trnL-F, although the topology recovered in this part of the tree has low
support (BP 55 - 69).
The heuristic search based on the rpoB-trnC matrix generated six equally
parsimonious trees of 657 steps, one of which is shown in Fig. 3. This analysis
included 1.416 characters, from which 15% were variable and 14% were parsimony
informative (Table 2). Sequences of P. stachyodes (Azevedo s.n., 318) were
unavailable because we were unable to amplify the DNA for these samples. The tree
obtained was similar to the ITS tree. However there is a lack of support along the
spine of the tree. Nevertheless, we still obtained the same two main clades of the ITS
analysis, clade A (with BP 100) and the other clade presenting the remainder species
(BP 100), including clade B (BP 100) and clade D (BP 81). No clade equivalent to
clade C of the ITS analysis is recovered. Instead, P. plantaginifolia is sister to clade
D (with BP 90), which in turn is sister to P. spiranthophylla (BP 92). Within Clade D,
P. oligantha samples are sister to a subclade where P. densiflora is sister to P.
lancifolia and P. ostenii (BP 96).
The Incongruence length difference test (ILD) did not detect significant
incongruence between the plastid regions (trnL-F × rpoB-trnC: p value = 0.49).
However, in the other data partition cpDNA × ITS the hypothesis of congruence was
53
rejected (p < 0.01). After careful inspection of individual analyses searching for
possible well-supported incongruences we found no strongly supported incongruent
patterns of relationship, and we decided to carry out a combined analysis of all data,
despite the ILD results.
The combined analysis produced 12 trees, one of which (randomly selected) is
shown in Fig. 4. This trees had L = 2028 steps, CI = 0.68, and RI = 80 (Table 2). The
strict consensus tree is nearly fully resolved. The combined analyses strongly
support the monophyly of Prescottia (BP 95), in agreement with the ITS tree, having
as sister-group the clade formed by Galeoglossum tubulosum and G. thysanochilum
with low support (BP 52). This pattern was not recovered in the individual analyses,
where there is a lack of resolution among most of the ingroup. Here, Spiranthinae are
sister to a well supported group (BP 92) comprising the Altensteinia clade sister to
Cranichidinae s.s., and Galeoglossum sister to Prescottia. Within Prescottia, as in the
ITS and rpoB-trnC analyses, two main clades are recovered, previously defined as
clade A (BP 100), and the other presenting the remainder species. Within the latter,
two subclades are present: clade B as defined in the ITS tree (BP 100), and the other
clade presenting two subclades: the clade C as defined in ITS (BP 87), and the clade
D (BP 97), as recovered in the rpoB-trnC analysis.
Bayesian analysis – The sequence models selected were: (i) the general
time-reversible model and gamma distribution (GTR + gamma) for ITS (ii) the general
time-reversible model with a proportion of invariant characters and gamma
distribution (GTR + Inv + gamma) for trnL-trnF, (iii) GTR + gamma for and rpoB-trnC,
and (iv) lset coding=variable for the ITS and (iv) rpoB-trnC coded indels. The
Bayesian analysis based on all DNA regions and coded indels of ITS and rpoB-trnC
(Fig. 5) produced a well-supported tree as assessed by posterior probabilities (PP).
Essentially, the same topology observed in the analysis of combined parsimony was
maintained. Spiranthinae being sister to a moderately supported group (PP 92)
comprising the Altensteinia clade as sister of a well-supported group (PP 100); that
includes a monophyletic Prescottia (PP 100) sister to Galeoglossum, which in turn is
sister to Cranichidinae s.s (PP 97). The infrageneric relationships recovered the
same topology as obtained in the combined analysis. The tree is fully resolved and
54
the majority of the clades recovered is highly supported, including clades A (PP 100),
B (PP 100), C (PP 100), and D (PP 100).
Discussion
Molecular evolution – Despite the ILD results, most phylogenetic patterns in
Prescottia based on different plastid and nuclear fragments were congruent.
Especially in terms of the establishment of the genus monophyly, the sister position
of Galeoglossum tubulosum and G. thysanochilum, and the subdivision into two main
groups: the clade A and the other formed by groups B, C and D. Incongruence
between DNA data sets in orchids has been found predominantly within genera at
species level (e.g. Goldman et al. 2004, Koehler et al. 2008). Some studies
demonstrated that although the tests indicated the presence of incongruence, the
combined analyses demonstrated data congruence (Yoder et al. 2001).
The combined DNA matrix with coded indels of ITS and rpoB-trnC includes
information from all regions. Since the parsimony and Bayesian analyses of the
combined data provided a similar topology and detailed information on the
phylogenetic relationship within the genus, we favor the results of these analyses
over all others, suggesting that the differences observed in the individual analyses
were caused by the character sampling error in single data sets and not by true
incongruence among DNA regions. Furthermore, the Bayesian analysis resulted in a
fully resolved and well-supported tree. For this reason, this tree is taken as the best
hypothesis of relationship for our study and, unless otherwise stated, the discussion
refers to it.
As expected, the two ITS spacer regions, ITS 1 and ITS 2, have the greatest
number of variable sites with the faster rate of change. ITS also presents the lowest
consistency index (Table 2). Undoubtedly, the data set with greatest contribution in
resolving clades was ITS, which can be explained by its greater number of variable
sites and their higher rate of substitution. ITS was more informative than trnL-F, the
same result was found by Soliva et al. (2001), Higgins et al. (2003) and van den Berg
et al. (2005). Our plastid data sets displayed lower variation in comparison with the
ITS, similar results have been observed in Salazar et al. (2003) and Álvarez-Molina &
55
Cameron (2009). The rpoB-trnC displays the greatest evolutionary rate between the
two plastid fragments used, confirming Shaw et al. (2005) results.
Intergeneric relationships – Chase (2003) resurrected Cranichidinae (sensu
Dressler 1981), putting back the genera transfered to Prescottiinae by Dressler
(1990, 1993). The Bayesian analysis of Salazar et al. (2009) support this approach.
The analyses presented here, except for the rpoB-trnC analysis, corroborate this
result, since Cranichidinae s.l. is recovered as monophyletic. Our analyses indicate
that Spiranthinae are sister to Cranichidinae s.l. Within Cranichidinae s.l. the
Altensteinia clade is sister of a group that includes Prescottia as sister to
Galeoglossum, which in turn is sister to Cranichidinae s.s.
The analyses sugest that Galeoglossum is the genus most closely related to
Prescottia. This result corroborated the results of Álvarez (2005), Figueroa et al.
(2008), Álvarez-Molina & Cameron (2009), and Salazar et al. (2009). Galeoglossum
has a restrict distribution in Mexico and Guatemala. Some morphological characters,
such as a cucullate lip and stigma with a single receptive area located on the ventral
surface of the column constitute synapomorphies of Prescottia.
Infrageneric relationships – The topologies obtained here indicate that the
informal groups proposed by Pabst & Dungs (1975) are not monophyletic. The
Prescottia colorans “alliance” is not monophyletic because P. leptostachya is not
included in the clade that contains the other species of that section. Besides that, P.
montana is part of this clade and not part of the P. plantaginea “alliance” as proposed
by Pabst & Dungs (1975); recovering the latter as polyphyletic, because besides that,
P. phleoides is not included in this clade. The Prescottia oligantha “alliance” and
Prescottia lancifolia “alliance” are also paraphyletic, once the whitish flower with lip
internally pilose appears here as a monophyletic clade, where P.densiflora is more
close related to P. lancifolia and not to P. oligantha as proposed by Pabst & Dungs
(1975). Due to the inconsistency of the morphological characters used to define the
four groups (Pabst & Dungs 1975), we suggest their rejection altogether. Given the
small number of species currently accepted (Chapter 3) we prefer not to establish
intrageneric divisions within Prescottia.
56
Species’ delimitation - Six of the 11 sampled species of Prescottia were
represented by more than one sample in each data set. None of the analyses
rejected the current species circumscription, since all accessions of each species
cluster together (PP 100). Two species complexes (around Prescottia oligantha and
P. stachyodes), composed of species with extremely variable morphology, also
emerged as monophyletic groups from these analyses, with high support (PP 100).
Species’ boundaries among these taxa have been questioned, and there are many
names available for species within each complex. In view of the fact that is very
difficult to distinguish its morphs, since they are defined by continuously variable
morphological characters, as leaf shape and size, and floral size, P. oligantha and P.
stachyodes have been considered in a broadened circumscription (Chapter 3). The
sequence data presented here are not sufficient to elucidate the relationship within
these clades, because they do not include an adequate sampling for that purpose.
Evolution of selected characters in Prescottia - In terms of vegetative and
floral morphological characters, little can be inferred based on the relationships
among different species of Prescottia. When grouping based on vegetative
characters, species groups delimited by sessile to petiolate leaves are not fully
congruent with the major groupings recovered in phylogenetic reconstruction. Those
species with long petiolate leaves are monophyletic and highly supported as an
synapomorphy of the clade A, and those with sessile, pseudopetiolate or short
petiolate leaves are paraphyletic.
In terms of the floral characters, when grouping based on flower color and
presence or absence of tricomas, we observe that those species of whitish flowers
with the inner surface of the lip pilose form a monophyletic and highly supported
group, whereas those species with greenish flowers and lip inner surface glabrous do
not form a monophyletic group, because the whitish flower group is within it.Change
from greenish to withish flowers is indicated as a synapomorphy for clade D. This
character evolved together with the presence of trichomes in the inner surface of the
lip, also synapomorphic. The greenish flowers with lip inner surface glabrous appears
to be the plesiomorphic character state. The arrangement of the flower into loose and
dense inflorescence has also evolved more than once within the genus. The species
within clade C share some morphological characters such as lip with outer surface
57
with trichomes at the base, and column with dorsal surface covered by trichomes,
which are synapomorphies of this clade.
Terrestrial habit is considered plesiomorphic in the Orchidaceae and in
Asparagales as a whole (Neyland and Urbatsch, 1995). Nearly all Orchidoideae are
terrestrials.The positioning of Prescottia lancifolia (an epiphyte or facultative epiphyte
species) suggests that it evolved from a terrestrial habit ancestor.
Distribution of Prescottia – Within the clade containing species of Prescottia
with long petiolate leaves (clade A), P. stachyodes has a widespread distribution; it
occurs in the extreme points of the genus distribution and displays one of the largest
ecological plasticity within Prescottia. It prefers humid and shaded forests, and
elevation from sea level to 3.600 m. The other species of this clade, P. montana, has
a more restrict distribution, occurring from Southeast of Brazil (plus Goiás, and
Bahia) to Argentina, where it grows in open areas, at elevations between 730 and
2,660 m.
The species within clade B are restricted to Brazil, with a more restricted
distribution. Prescottia leptostachya and P. mucugensis are restricted to Bahia and P.
phleoides occurs in southeastern Brazil (plus Goiás). The members of this clade
have a preference for open areas, at elevations between sea level and 2,000 m.
Species in Clade C are also restricted to Brazil and from open areas. P.
spiranthophylla is endemic to Rio de Janeiro, whereas P. plantaginifolia occurs
throughout the northeastern to southeastern Brazil. The whitish flower species (clade
D), with the exception of P. oligantha, present a restricted distribution. Prescottia
oligantha and P. lancifolia inhabit shady sites in moist and wet forest, whereas P.
densiflora and P. ostenii have a marked preference for open vegetation.
The results indicate that the widespread (reaching Central America, West
Indies and Florida), and vegetatively highly polymorphic species, included in this
genus belong to two distinct clades (Prescottia stachyodes clade A, and P. oligantha
clade D).
58
Conclusions
The resulting phylogeny improves our understanding about the relationship
within Prescottia species. It had been useful in helping to clarify the circumscription of
Prescottia species, and was also used as the base for discussion in the taxonomic
monograph presented in chapter 3.
Although the present analyses included most of the species currently
recognized in Prescottia (Chapter 3), covering most of the morphological diversity
found in the genus, the rare Brazilian species P. glazioviana, and the extra Brazilian
long petiolate-leaved species (Prescottia carnosa, P. lojana and P. ecuadorensis)
were not included in this study. The inclusion of them would permit a clear
understanding about their relationship.
Further studies utilizing more infraspecific samples, including samples from
different sites of the wide range of the species distribution, and different molecular
markers at population level and phylogeography are recommended to clarify
questions about the relationship within each complex. Population samples are
already being collected for that purpose.

cons. prop.
Typus: P. plantaginea Hook.
When Hooker first published this generic name and
description by Lindley in 1824, it was spelled Prescotia and
said to be named after “John Prescot”. Later (in Bot. Reg.
22: t. 1916. 1836 & Gen. Sp. Orchid. Pl.: 453. 1840),
Lindley changed it to Prescottia, with the knowledge that
“John Prescott” (Lindley, l.c., 1836) spelled his name
accordingly. Since then, some authors have used the original spelling, e.g., Steudel (Nomencl. Bot. ed. 2, 2: 393.
1841), Vöth (in Orchidee (Hamburg) 27: 148–153. 1976),
Farr & al. (in Regnum Veg. 102: 1409. 1979), and
Ackerman (in Lindleyana 4(1): 42–47. 1989), while others
have adopted the corrected spelling, e.g., Cogniaux (in
Martius, Fl. Bras. 3(4): 256. 1895), Hoehne (Fl. Bras. 12(2):
95. 1945), Pabst & Dungs (Orchidaceae Brasil. 1: 123.
1975), Brummitt (Vasc. Pl. Fam. Gen.: 349. 1992), Dressler
(Phylog. Classif. Orch. Fam.: 120, 268. 1993), Greuter & al.
(in Regnum Veg. 129: 919. 1993), and Ackerman (in Mem.
New York Bot Gard. 73: 142. 1995 & in Pridgeon & al.,
Gen. Orchid. 3: 47. 2003). Current usage, as reflected in the
results (729 hits to 127) of a Google search, favors the
spelling Prescottia. The genus includes 24 species extending from Florida (U.S.A.) through the West Indies to northeastern Argentina with the greatest diversity in Brazil. To
avoid any further disagreement over the spelling of the
generic name, it seems desirable to conserve it as proposed
above.

Prescottia plantaginifolia Lindl. ex Hook.,
Exot. Fl. 2: ad t. 115. Aug 1824, nom. rej. prop.
Prescottia plantaginea is an herbaceous plant commonly found in shady sites in wet forests throughout the
Brazilian Atlantic Forest. For the epithet of the only original species of this genus Hooker used the spelling “plantaginifolia”, which he ascribed to Lindley, in the heading, in
the text, and at the head of the caption for the illustration,
but on the plate itself (and on Hooker’s type) the name
appeared as “plantaginea”, without ascription. These two
spellings at first glance may appear to be orthographic variants (Art. 61.2; Greuter & al. in Regnum Veg. 138. 2000) of
one name, but they are more properly viewed as two etymologically different names of equivalent priority based on
the same type, i.e., alternative names (Art. 34.2). In this situation, Art. 11.5 determines the name that has priority is
that which the first subsequent author adopted while simultaneously rejecting the other (see Art. 11, Note 2). After
Hooker’s 1824 publication, the name P. plantaginifolia was
adopted in Loddiges (Bot. Cab. 10: t. 990. 1825) and
Sprengel (Syst. Veg. 3:706. 1826) but without mention of
the alternative name. Lindley later (l.c., 1836, 1840) used P.
plantaginea, but again without explicitly rejecting the alternative name. Steudel (l.c.) appears to have been the first to
make an effective choice under Art. 11.5, by adopting P.
plantaginifolia while listing P. plantaginea as a synonym,
thereby establishing that P. plantaginifolia has priority.
Some authors, e.g., Vöth (l.c.), Farr & al. (l.c.), Ackerman
(l.c., 1995, 2003), and Greuter & al. (l.c.) have adopted this
name, while others, e.g., Cogniaux (l.c.), Hoehne (l.c.), and
Pabst & Dungs (l.c.), have used the name P. plantaginea
later preferred by Lindley. Current usage favors P. plantaginea, as the results (39 hits to 2) of a Google search on
both names indicate, but to preserve this name requires conservation.
In the protologue, Hooker clearly indicated which portions were provided by Lindley. The Latin generic diagnosis ascribed to Lindley would be sufficient, under Art. 42, to
validate both his generic and specific names, since the
genus was originally monotypic. However, Hooker provided a separate validating description in English following his
citation of “Prescotia plantaginifolia, Lindl. Hist. Orchid.
ined.”, so Art. 46.4 would imply that he is the author of this
name as well as the competing P. plantaginea, which cannot
be associated with Lindley. Hooker’s description was based
on a plant cultivated in the Glasgow Botanic Garden,
received from the Horticultural Society of London (where
Lindley was then employed as a garden clerk), whose material had in turn originated with an 1822 collection by John
Forbes from “Rio Janeiro”. The original collection is represented by a (cultivated?) specimen of this taxon citing
Forbes (but dated 1824) in the Lindley Herbarium at K, and
another cultivated specimen (also dated 1824) from the
Herbarium Hookerianum now exists in the general herbarium at K. Both of these elements, having been mentioned by
Hooker, can be taken as syntypes, since they are probably

associated with Hooker, labelled “Prescotia plantaginea” in
his handwriting, and more closely resembling the published
plate is here designated as lectotype.

nom. utique rej. prop.
Lectotypus (hic designatus): Swartz s.n. (W [RchbOrch] No. 25291).
When Swartz first published Cymbidium muricatum
from Jamaica, the description (in Nova Acta Regiae Soc.
Sci. Upsal. 6: 76. 1799) was brief, though “suberect” with
“muricate capsule” point to the species later described as
Dichaea morrisii Fawc. & Rendle (in J. Bot. 48: 107. 1910);
he also cited his then-unpublished treatment for Flora
Indiae occidentalis. In 1806 he again described the plant
(Fl. Ind. Occid. 3: 1454. 1806) in more detail as with leaves
1.5 inches long, and stressed that the plant was more erect,
much wider and had larger flowers and fruits with shorter
pedicels (“sessile”) than Epidendrum echinocarpon Sw.
(Prodr.: 124. 1788) [= D. pendula (Aubl.) Cogn.]. This
expanded description fits only the later D. morrisii Fawc. &
Rendle., but there has been much confusion as to the application of Swartz’s name.
Dichaea muricata (Sw.) Lindl. was interpreted as the
correct name for D. latifolia Lindl. by Cogniaux (in Martius,
Fl. Bras. 3(6): 487, 488. 1906 and in Urban, Symb. Antill. 6:
671. 1910) and Garay & Sweet (in Howard, Fl. Lesser
Antill., Orchidaceae: 219. 1974). Indeed, this name has been
used rather consistently in this sense in the West Indies, until
Ackerman (in Mem. New York Bot. Gard. 73: 41. 1995)
treated D. latifolia as distinct from D. muricata. Then Nir
(Orch. Antill.: 88. 2000) argued that the descriptions could
apply only to the species later named D. morrisii.
On the mainland, in contrast, floristic workers have
used the name for any medium-sized member of Dichaea
subgen. Dichaea with wide, thin leaves, including D.
costaricensis Schltr., D. cryptarrhena Rchb. f. ex Kraenzl.,
D. laxa (Ruiz & Pav.) Poepp. & Endl., D. histrio Rchb. f.,
D. poicillantha Schltr., and D. splitgerberi Rchb. f., among
others (Allen in Ann. Missouri Bot. Gard. (Fl. Panama) 36:
239. 1949; Ames in Publ. Field Mus. Nat. Hist., Bot. Ser.
(Fl. Costa Rica) 18: 212. 1937; Ames & Correll in

968. 1961; Williams in Ceiba 5: 249. 1956, among others).
This misuse has been so persistent that when Hamer and
Garay (Orq. Salvador 1: 143. 1974) recognized that
Dichaea tuerckheimii Kraenzl., 1923 (non Schltr., 1916)
was a distinct species, they renamed it as D. muricatoides,
an allusion to a supposed resemblance to the chimaeric D.
muricata (note that the leaves of D. muricatoides were characterized as being “much bigger than those of D. muricata”). Even a species as distinct as D. neglecta Schltr. is one
of several that have been treated as varieties of D. muricata, and herbarium identifications as D. muricata may be
found on almost any species of Dichaea subgen. Dichaea.
The name Dichaea muricata clearly has been “persistently used for a taxon or taxa not including its type” (ICBN
Art. 57.1; Greuter & al. in Regnum. Veg. 138. 2000). Garay
& Sweet (l.c.) cited “Type: Jamaica, without proper locality. Coll. Swartz s.n.! (S)”, an effective typification under
Art. 7.11 of the ICBN. Since Garay & Sweet interpreted D.
muricata as the earliest name for D. latifolia Lindl., the
specimen must have represented that species, though such a
Swartz specimen has not been found in recent years.
Dichaea latifolia, like D. pendula, is laxly pendent, rather
than suberect, and has narrower stems, smaller leaves and
smaller, long-pedicellate flowers and fruits, and is thus in
conflict with the protologue. As already mentioned,
Swartz’s characterization of Cymbidium muricatum fits the
species later described as Dichaea morrisii and discussed
by Schweinfurth (in Bot. Mus. Leafl. 6: 8–9. 1938). The
specimen at S cannot therefore have been part of Swartz’s
original material for Cymbidium muricatum; thus this specimen, if it exists, could only be regarded as a neotype.
Nir (l.c.) later stated, after referencing Folsom’s unpublished 1987 thesis on Dichaea in his introductory comments
to the genus: “As pointed out by Folsom, the only extant
Swartzian type specimen of D. muricata (C)”. But he then
proceeded (l.c.: 91), under his treatment of D. muricata, to
only list two supposed unseen Swartz syntypes at S and BM
under the heading of “Type”. There is indeed a very small,
sterile specimen at C labelled “missit Swartz, Herbarium
Vahlianum” and “Cymbidium muricatum”, but Nir’s action

Lectotypifications in Prescottia (Orchidaceae -Orchidoideae)
Cecília Azevedo1,3 & Cássio van den Berg2
Summary. Typifications of 11 species names are presented as a result of work on a taxonomic revision of the
genus Prescottia Lindl.
Key words. Orchidaceae, Prescottia, lectotypification.
Introduction
Prescottia Lindl. includes 24 species (Ackerman 2003),
of which 17 occur in Brazil (Pabst & Dungs 1975).
These species generally occur between 500 to 1,500
m altitude and are distributed from Florida to
northwestern Argentina. They are usually found in
very small populations mainly in humid forests. The
genus has rather variable morphology and several
species are difficult to delimit, which has resulted in
many synonyms. Consequently, from the 70 species
originally described, only 24 are currently accepted.
In ongoing studies for a monograph of Prescottia, type
materials of most names published in the genus have
been studied. Lectotypes are designated here for 11
of these names.
by the author of the species, e.g., notes in their own
handwriting, as well as those deposited in herbaria at
which the species’ authors worked.
In each species lectotypification, we give as
‘protologue’ the exact text provided by the author at
the original description and, after the designed
lectotype, the information obtained from the
specimen label.
Lectotypifications
1. Cranichis oligantha Sw. (1788: 120). Protologue:
‘Jamaica’, without collector or date. Lectotype
(chosen here): Jamaica (mont. Caerul.), Swartz s.n.
(BM!).
= Prescottia oligantha (Sw.) Lindl. (1840a: 454).
Material and methods
The protologues of all published names were
examined, and original material was sought and
studied in the following herbaria: ALCB*, B, BAH,
BHCB, BM*, CAY, CEN, CEPEC*, CESJ, CGMS, CM,
COR, CR*, CTES, CVRD, EAC, ESA, ESAL, G, GH,
GUA, HAS, HASU, HB*, HEPH, HMS, HRB*, HRCB,
HUA, HUFU, HUEFS*, HURG, HXBH, IAC, ICN,
INPA, IPA, JPB, K*, K–L*, M*, MAC, MBM*, MBML*,
MG, MVFA, MVM, NY, P*, PACA, PAMG, PEL, PEUFR,
PMSP, R*, RB*, RBR, RUSU, S, SJRP, SMDB, SP, SPF,
TEPB, UB, UEC, UFMT, USJ*, VIC and W* (acronyms
according to Holmgren et al. 1990). Specimens were
studied by visiting some of the herbaria (indicated with
*) or otherwise as loans to HUEFS and K.
For the designation of the lectotypes, we considered
specimens bearing clear indications of first-hand study
Cranichis oligantha was described by Swartz without
information about the specimen examined. As
Swartz’s West Indian collections at S are not complete
and as Swartz was very liberal with his specimens,
Swartz types can be found, for instance, at BM
(Stafleu & Cowan 1986).
Fawcett & Rendle (1910), Garay & Sweet (1979)
and McLeish et al. (1995) determined that the type of
Cranichis oligantha is at BM. However, Garay (1978)
indicated that the type is at S, demonstrating the
current confusion about the type. Although Garay
(1978) cited the specimen at S as type, he wrote:
“Type: Jamaica, Blue Mountains, Swartz s.n.! (S)”, the
specimen at S does not bear this information. We
found only one specimen at S that is very similar to
the unpublished drawings of West Indian Plants by

Olof Swartz in the library of the Royal Swedish
Academy of Sciences, Stockholm, but without
collector’s name or location. Despite the similarities,
there is no clear link between this material and the
protologue information. On the other hand, there is
a specimen at BM annotated, on the back of the
sheet, in handwriting: “Jamaica (mont. Caerul.) Sz.”.
This agrees in part with the protologue and especially
with the later citation of Swartz (1806): “C. oligantha –
in montibus summis Jamaicae (cum duabus
sequentibus hanc legi in adscensu montium
caeruleorum)”. Stearn (1980) explains that the
herbarium specimens from West India were in Sir
Joseph Banks’ herbarium, now in the British Museum
(BM). For these reasons, we choose the BM specimen
as the lectotype of C. oligantha.
2. Cranichis stachyodes Sw. (1788: 120). Protologue:
“Jamaica” without collector or date. Lectotype
(chosen here): Jamaica (Blue Mountains), Swartz s.n.
(BM!).
= Prescottia stachyodes (Sw.) Lindl. (1836: 1916).
Cranichis stachyodes was described without information
on the specimen examined. There is a specimen at S
without collector’s name or location, and without any
clear links to the protologue information. At BM,
however, there is a specimen annotated on the back
in handwriting: “Jamaica (Blue Mount.) Swartz”.
Fawcett & Rendle (1910), Garay & Sweet (1979),
Garay (1978) and McLeish et al. (1995) cited that the
type of Cranichis stachyodes is at BM, although, Serna
& Ferrari (1998) cited that it is at S and Nir (2000)
cited that it at S and BM. To avoid more confusion
about the type, the BM specimen is selected here as
the lectotype of C. stachyodes, as this is the only
specimen that can be undoubtedly attributed to
Swartz and to the type location.
3. Decaisnea densiflora Brongn. (1829: 39). Protologue:
“L’ile Sainte-Catherine au Brésil”, without collector
or date. Lectotype (chosen here): Brazil: Santa
Catarina, A. Brongniart s.n. (K-L!; isolectotype P!).
= Prescottia densiflora (Brongn.) Lindl. (1840b: 52).
In the protologue there is no information about the
provenance of the type. We found two specimens of
Decaisnea densiflora, one at P, where most of
Brongniart’s specimens are deposited, and another at
K-L. They are both annotated with the same
information as that given in the protologue. The
specimen at K-L is the specimen drawn for the
original publication and has a copy of the drawing
added to it. When Lindley (1840b) transferred D.
densiflora to Prescottia densiflora, he said: “I possess an

KEW BULLETIN VOL. 62(4)
excellent specimen of D. densiflora, through the
liberality of M. Ad. Brongniart”. It seems clear not
only that Brongniart gave this specimen to Lindley,
probably after describing D. densiflora but that this
material was clearly the one used to describe the
species. Because the specimen given to Lindley is the
specimen illustrated, the K-L specimen is here
designated as the lectotype of D. densiflora, whereas
the other material is considered an isolectotype.
4. Prescottia glazioviana Cogn. (1895: 261). Protologue:
“Habitat ad cacumen mont. Itatiaia in Campo de
Silverio prov. Rio de Janeiro: Glaziou n. 6729 in herb.
Berol. non alior; ad Serra dos Órgãos: Gardner 5884 in
herb. Berol. et Kew.” Lectotype (chosen here): Brazil:
Rio de Janeiro, Summit of Órgãos Mountains, Gardner
5884, March 1841 (K-L!; isolectotype K! (Herb.
Benthamianum); K! (Herb. Hookerianum); BM!; R!).
Prescottia glazioviana was described on the basis of two
syntypes, Glaziou 6729 and Gardner 5884. The first,
Glaziou 6729, cited by Cogniaux as being only at B, was
not found, and was probably destroyed during the
World War II. The second was cited to be at Berlin
and Kew. Actually, we found six specimens of Gardner
5884, three of them at K, of which was one stamped
“Herbarium Hookerianum 1867” (1867 being the
year that Kew bought Hooker’s herbarium) and the
other “Herbarium Benthamianum 1854” (1854 being
the year that George Bentham donated his herbarium
to Kew). This means that these two collections had
been kept at Kew for about 30 years before Cogniaux’s
description. The third Kew specimen is in Lindley’s
herbarium. There is one specimen at BM and one at
R, both bearing similar handwritten labels. The final
specimen is at G, and has a different date (July 1842).
This specimen has phototype at NY. Because the
information about the date does not agree with the
other specimens, we prefer not to consider the G
specimen as an isolectotype. Cogniaux cited that the
specimens were at Berlin and Kew, but the Gardner
material at Berlin (B) was also destroyed during the
war. Cogniaux could have examined any of the three
specimens at Kew, but none of them was determined
by him or has his handwritten notes. Because all the
materials deposited at Kew are equivalent in
annotations, we chose the well-preserved material at
K-L as lectotype of P. glazioviana, leaving the
remaining duplicates at K, BM and R as isolectotypes.
5. Prescottia lancifolia Lindl. (1840a: 453). Protologue:
“in Brazilia, Gardner 681; prope Ilha Grande inter
humum, Descourtilz (hab. s. sp.).” Lectotype (chosen
here): Brazil: Gardner 681 (K-L!; isolectotype BM!; G!;
K!; NY!; P!; W!).
79
LECTOTYPIFICATIONS IN PRESCOTTIA (ORCHIDACEAE-ORCHIDOIDEAE)
Lindley cited two syntypes in the protologue of
Prescottia lancifolia, Gardner 681 and Descourtilz s.n. We
found seven specimens annotated as Gardner 681,
which have different labels and different dates. The
most curious among them is the material at Kew, in
which Gardner says that it was a new species: “681.
Prescotia parviflora Gard. Mss. This I believe to be an
undescribed species of Prescotia. It grew upon the
moss covered stump of an old tree in a shady place —
Flowers white — May 1837 G. Gardner” (handwriting).
It is stamped “Herbarium Hookerianum 1867”. The
BM material bears the same year, but a different
month, and is annotated as follows: “681. On the
stems of old trees, Órgão Mountains, April 1837
Prescottia lancifolia Lindl.” (handwriting). The material
at Lindley herbarium has no date, and is annotated as:
“Rio de Janeiro — Gardner” (typewritten) “no. 681,
Prescottia lancifolia” (handwriting). This material
includes a drawing of the lip made by Lindley. The G,
NY and W specimens have a different years from the
BM and K material. The G material is annotated:
“Bresil — Organ mountains. (Serra dos Órgãos) M.
Gardner. (Recu en 1838)” (typewritten) “no. 681”
(handwriting), and was latter determined as Prescottia
lancifolia by A. Cogniaux. The NY material is
annotated: “In Brasilia ad montes “Serra dos Órgãos”
legit Gardner! no. 681, 1838” (handwriting). The W
material is annotated as: “Orchidea, Brasilia, Gardner
no. 681, III/1838” (all handwritten). There are
phototypes at NY of the BM and G specimens.
Descourtilz’s syntype was not found, and so the
syntype Gardner 681 housed in Lindley’s herbarium
(K-L) is chosen here as lectotype.
6. Prescottia ostenii Pabst (1979: 19). Protologue:
“Uruguay, Dep. Canelones, La Floresta, in uliginosis

Holotypus HB 1233 omitted at original description.
Lectotype (chosen here): Uruguai: Canelones, La

Prescottia ostenii was first described in Pabst (1979),
but a holotype was not explicitly designated as such
by the author. In a latter note, Pabst (1980) cited:
“holotypus HB 1233, omitted at original description”,
which corresponds to: Uruguay, Dep. Canelones, La
Floresta, C. Osten 16918, 30 Sep. 1923. This is a
different specimen from that cited in 1979. Article
37.3. of the International Code of Botanical
Nomenclature (Greuter et al. 2000) states that for the
name of a new species, mention of a single specimen
or gathering or illustration, even if that element is
not explicitly designated as type, is acceptable as
indication of the type. Only on or after 1 January
1990, as Article 37.5. says, must indication of the type
653
include one of the words ‘typus’ or ‘holotypus’. Thus,
in this case, the name was validly published in 1979,
and Osten 22939 must be accepted as the type, not
Osten 16918 (HB 1233). We found three specimens of
Osten 22939, one at S and two at GH. The materials at
GH are marked ‘Osten 22939 b’ and have no
identification label by Pabst, hence we are not
accepting them as isolectotypes. There is no
specimen of Osten 22939 in Pabst’s herbarium (HB),
but the specimen at S has Pabst’s determination label
and is here chosen as the lectotype of P. ostenii. There
are also two specimens of Osten 22939 at MVM and
another one at MVFA without Pabst’s identification,
considered here as isolectotype.
7. Prescottia smithii Schltr. (1920a: 52). Protologue:
“Magdalena: Santa Marta, 4000 ft., H. H. Smith 2277.
March.” Lectotype (chosen here): Colombia:
Magdalena: Santa Marta, above las Partidas. H. H.
Smith 2277 (NY!; isolectotypes K!, GH!; CM!)
= Prescottia stachyodes (Sw.) Lindl. (1836: 1916).
In the protologue, there is no information about
where the type was deposited. Four specimens of
Smith 2277 were found at NY, K, GH, CM. The
material at GH is annotated by Smith as an isotype
collection on 15 June 1928, after the original
description. There is also a copy of drawings and
analyses from Schlechter’s material at GH, made
under supervision of Rudolf Schlechter. The original
material of Prescottia smithii was probably at B, but it
could not be found and was probably destroyed
during World War II, together with Schlechter’s
original specimens. The original materials of Smith
were distributed by NY, where the material is
annotated as isotype. Among the isotype, the original
material belonging to Smith and deposited at NY, is
selected as the lectotype of P. smithii.
8. Prescottia truncicola Schltr. (1920b: 319). Protologue:
“Paraná: Serra do Mar, Carvaelho, in silva primaevis,
ad truncos putridos — no. 18154, flor. Sept. 1911;
Serra do Mar, Monte Alegre, in terra silvosa, no.
10290, flor. Sept. 1910.” Lectotype (chosen here):
Brazil: Paraná, Serra do Mar, Carvalho in silv. prim.
ad trunc., 12 Sept. 1911, P. Dusen 18154 (AMES!;
isolectotype GH!).
= Prescottia lancifolia Lindl. (1840a: 453).
Schlechter cited two syntypes in the original
description of Prescottia truncicola, Dusén 18154 and
Dusén 10290. There is one specimen at Dusén’s
herbarium, which is now incorporated to MBM, with
a handwritten label bearing the information 10290
and year 1910, which agrees with the protologue.

There are two specimens of Dusén 18154 at Harvard
University Herbaria, annotated in Schlechter’s
handwriting with the same information given in the
protologue and determined by him as P. truncicola.
One is from GH without date (barcode 103629) and
has three separated plants glued to the same sheet,
and the other is from AMES, more complete, with
date (barcode 103628), and bearing a single plant.
The original material of P. truncicola was probably at B
and destroyed during World War II. There is no
evidence that Schlechter had examined the syntype at
MBM. Thus, we chose the AMES syntype as the
lectotype of P. truncicola.
Schlechter’s Prescottia
Schlechter’s original materials were at B, and most
were destroyed during World War II. Therefore, we
chose to lectotypify the names for which it was
impossible to locate syntypes or isotypes with
drawings and analyses from Schlechter’s Herbaria,
made under the supervision of Rudolf Schlechter.
9. Prescottia gracilis Schltr. (1920a: 51). Protologue:

Summary. Previously known from only two specimens collected in Uruguay,
Prescottia ostenii Pabst, is herein reported for the first time in Rio Grande do Sul,
Southern Brazil. Several morphological features lacking in the original description
are described and illustrated for the first time. The taxonomic affinities of this
species are discussed, based on vegetative and floral morphology.
Key Words. Brazil, new record, Orchidaceae, Prescottia.
Introduction
Prescottia Lindl. is a Neotropical orchid genus of ca. 24 species distributed from
Florida to north-western Argentina; although particularly species-rich in Brazil
(Ackerman 2003). This genus involves both widely distributed and quite localized
taxa. The vast majority of the species are terrestrial herbs (geophytes), with a basal
rosette of leaves and a terminal, many-flowered inflorescence (spike). The flowers
are characteristically sessile, helmet-like and non-resupinate. The fruit is a capsule

and the seeds are minute and dust-like (Ackerman 2003; Dressler 1993). The roots
are fasciculate, fleshy, subterranean and villous (Ackerman 2003).
Prescottia ostenii was first described by Pabst (1979), from specimens collected at
Canelones, Uruguay. It is a very rare, poorly known species, and it is recorded here
for the first time from Brazil. So far, it was only known from two specimens: C.Osten
16918 (HB), and C.Osten 22939 (GH, MFVA, MVM, S), which were collected in
September 1923 and October 1933, at the same place in Uruguay. Notably, this
species was recently collected by us in Rio Grande do Sul, a southern Brazilian
state. The original description of P. ostenii (Pabst 1979) is quite poor regarding floral
details (especially flower shape, column and pollinarium details) and the original
illustrations consisted of a drawing of the habit plus a crude diagram of the perianth.
Both the drawing of the habit and perianth parts suggest that Pabst (1979) based his
description on specimens in bud. The discovery of this species in Brazil compelled us
to the elaboration of more detailed illustrations, including several features omitted in
the original description. The aim of the following contribution is thus twofold: 1) to
record P. ostenii for the first time for the Brazilian orchid flora; and 2) to provide a
more complete description of this plant’s morphological features, with emphasis in
characters that may be useful to elucidate taxonomic affinities.
Material and Methods
The protologue of the species (Pabst 1979) has been examined. Looking for
additional, possibly overlooked collections of P. ostenii, specimens of the following
herbaria have been studied: ALCB*, B, BAH, BHCB*, BM*, CAY, CEN, CEPEC*,
CESJ, CGMS, CM, COR, CR*, CTES, CVRD, EAC, ESA, ESAL, F, G, GH, GUA,

Holmgren & Holmgren 1998). Specimens were studied by visiting some of the
herbaria (indicated with *) or otherwise as loans to HUEFS and K. Original materials
at HB, GH and S were examined.
The Brazilian specimens (see Distribution) were pressed and deposited at ICN. One
inflorescence was preserved in 70 % ethanol and its flowers were used to draw floral
features. Emphasis was put on characters absent or poorly illustrated in the
protologue. Floral features were drawn using a binocular stereomicroscope with a
camera lucida attachment. Living specimens were photographed with a digital (Sony
Cyber-shot DSC-H7) camera. In addition, floral details of a living specimens were
photographed with the help of a digital camera (Nikon Coolpix) attached to a
stereomicroscope.

HABITAT: Either in Uruguay or Brasil, P. ostenii has been found among marshy,
paludicolous, open vegetation very near of the Atlantic coast (the Brazilian
populations were found less than 200 m from the sea).
87
CONSERVATION STATUS. Prescottia ostenii was hitherto known only from the type
locality, and only from two collections (see above). Apparently, it has not been
collected again in Uruguay and the type locality has been considerably modified as a
consequence of urban development (Eduardo Marchesi, pers. comm.). Only now,
after more than 70 years, it has been recollected. For the time being, the Brazilian
population is the only surviving population we are aware of. Indeed, P. ostenii is quite
inconspicuous and may have been overlooked by preceding researchers or may
have been confused with the widespread Prescottia densiflora (Brogn.) Lindl. We
have to say, however, that no misidentified specimens have been located by us so
far. More fieldwork in coastal Rio Grande do Sul is necessary to confidently assess
the status of this species in Brazil. In this context, P. ostenii should be provisionally
considered as DD (data deficient, according to IUCN criteria) regarding its
conservation status.
ETYMOLOGY: In honor of Dr. Cornelius Osten, its first collector.
NOTES. Prescottia ostenii is one of the most distinctive species in the genus, and is
easily differentiated by its short robust habit, only 5-8 cm tall (Fig 1A) when in flower,
and a dense and thick inflorescence (Fig 1A-C, Figure 2A). Some confusion was
caused by Pabst (1979) when citing the type. Therefore, a lectotype had to be
designated (Azevedo & Van den Berg 2007).
Overall, the plant resembles very much P. densiflora in vegetative and, to a lesser
degree, floral features. This resemblance was already highlighted by Pabst (1979).
By checking the type specimen (Osten 22939, S), we noticed that in 1955
(22/02/1955); according to an identification label Pabst had previously identified this
taxon as “Prescottia densiflora Lindl. forma nana”. This name, however, was never
88
validly published and therefore constitutes a nomen nudum. Indeed, Pabst (1979) did
not mention his preceding identification in the protologue of P. ostenii (Pabst 1979).
Both P. ostenii and P. densiflora display sessile, rosulate leaves (Figure 1A), as well
as multiflorous and congested inflorescences (Figure 2A-C, Figure 2A). However,
inflorescences are much taller (up to 30 cm) in P. densiflora. In both species the
labellum is deeply concave and pilose in its inner surface (Figure 2B). Another
shared feature is the basal adnation of the lateral sepals, delineating a hood-like
structure that partially conceals the labellum (Figure 2C). Whereas the lateral sepals
have strongly revolute apices in P. densiflora (Singer & Sazima 2001); the sepals in
P. ostenii are erect and straight. As in P. densiflora, the column of P. ostenii is short
and stout and provided with two lateral column appendages (Figure 1D, Figure 2 GH) (Singer & Sazima 2001; Singer & Cocucci 1999). Pollinarium features are also
quite similar in both species. However, the pollinarium of P. ostenii can only be
removed from very young, just opening flowers. Two or three days after blooming,
the pollinarium displays a wet, pasty consistence and it is not possible to remove it
from the clinandrium anymore. These preliminary observations made in living flowers
suggest that P. ostenii is autogamous; self-pollination being achieved by the passive
contact of the edges of the pollinia and the stigmatic secretion. By observing the
column, it is easy to notice that there is no physical separation between the edges of
the pollinia and the edge of the broad stigmatic surface (Figure 1D, Figure 2 G-H).
This mechanism of self-pollination may be widespread among orchidoid terrestrial
Orchidaceae and has already been suggested to occur in a few other Prescottia
species in Central America (Ackerman 2003). In contrast, P. densiflora is selfcompatible, but pollinator-dependent (Singer & Sazima 2001; Singer & Cocucci
1999).
89
After checking 10 fresh flowers and 13 alcohol-preserved flowers of P. ostenii, we
found no evidence of protandry in this taxon. Protandry was already reported for
some Prescottia species with long columns, such as P. stachyodes (Sw.) Lindl. and
P. montana Barb. Rodr.; but it is likely absent in taxa with short, stout columns
(Singer & Sazima 2001).
It is important to stress that P. ostenii and P. densiflora dwell in very different
conditions. Prescottia densiflora always occurs in humid, tough, well-drained soils.
Prescottia ostenii dwells in full-sun, with its roots underwater or in very moist
conditions. To our knowledge, P. ostenii is the only species in the genus able to
thrive in such conditions. The protologue of P. ostenii mentions that the plant was
found among several other water-tolerant plants, such as Drosera brevifolia Pursh
(Droseraceae), Eriocaulon modestum Kunth (Eriocaulaceae), Utricularia sp.
(Lentibulariaceae) and Laurembergia tetrandra Kanitz (Haloragaceae). The Brazilian
specimens were found among almost identical vegetation, very close to a population
of the rare Gunnera herteri Osten (Gunneraceae).
Ongoing molecular analyses (Azevedo & Van den Berg, in prep.) suggest that P.
ostenii belongs in a clade composed of the species with small, white-coloured flowers
and similar floral features (stout column, pilose inner labellum surface, etc). It is
important to stress that even if Pabst (1979) proposed a morphological affinity
between P. ostenii and P. densiflora, other species such as P. lancifolia Lindl. and
also P. oligantha Lindl. also share a significant number of floral features with P.
ostenii. Indeed, overall flower shape in P. ostenii more closely resembles P.
lancifolia, especially regarding the shape and position of the lateral sepals, which are
straight in both species (vs. folded in P. densiflora). The forthcoming phylogeny of the
90
genus Prescottia (Azevedo & Van den Berg, in prep.) will provide a solid framework
to critically assess the affinities between all these aforementioned taxa.
Prescottia ostenii can easily be separated from P. lancifolia and P. oligantha on the
basis of foliar shape: leaves in P. ostenii are sessile, these of P. lancifolia are
petiolate and lanceolate and these of P. oligantha are shortly petiolate. Because P.
ostenii and P. densiflora share sessile rosulate leaves and superficially similar
flowers, both taxa could be confused either in the form of pressed vouchers or in the
field. However, as shown above, both species can be easily separated through a
consistent set of ecological and morphological features. The following artificial key
summarizes the most useful characters to set apart the species:
1. Plants growing in marshy conditions. Inflorescences up to 8 cm high. Lateral
sepals straight, covering the labellum almost completely .................. P. ostenii
1. Plants not growing in marshy conditions. Inflorescences much taller, up to 30
cm high. Lateral sepals folded, with revolute apices ............... P. densiflora

Prescottia Lindl. is a genus of primarily terrestrial orchids. The flowers are nonresupinate, with lateral sepals basally connate forming a short cup. The lip is cucullate,
basally auriculate, with the inner surface glabrous to pilose, enclosing the column. The genus
has a broad distribution in the Neotropics, from Florida to Northwestern Argentina, although
most species occur in Brazil (Ackerman 2003).

The Chapada Diamantina is located in the interior of Bahia state, Northeast Brazil. It is
a mountain range of outcrops of quartzite, sandstone and gneiss, ranging from 700 to over
2,000 m and is an important centre of diversity of the Brazilian mountain flora, where many
genera show a remarkable degree of diversification and large numbers of endemic species
occur (Harley & Simmons 1986; Giulietti et al. 1987, 1997; Giulietti & Pirani 1988; Alves &
Kolbek 1994; Harley 1995; Conceição & Pirani 2005, 2007). The vegetation in this area is
dominated by campo rupestre, an herbaceous-shrub vegetation that develops on open rocky
ground at elevations above 900 m, and is related to the Caatinga (Harley 1995). The district
of Guiné presents a very rich flora (Conceição et al. 2007), being located on the western
border of the Serra do Sincorá and the Chapada Diamantina National Park in the municipality
of Mucugê (12°45' S and 41°30' W).
Four Prescottia species have been recently recorded for the Chapada Diamantina: P.
densiflora (Brongn.) Lindl. (material not seen), P. leptostachya Lindl., P. montana Barb.
Rodr. and P. stachyodes (Sw.) Lindl. (Toscano de Brito 1995; Toscano de Brito & Smidt
2005; van den Berg & Azevedo 2005; Azevedo & van den Berg 2007). A fifth species has
been discovered for the same area and is here described and illustrated.

DISTRIBUTION. BRAZIL: Bahia.
SPECIMENS EXAMINED. BRAZIL. State of Bahia, Chapada Diamantina, Municipality of
Mucugê, District of Guiné, Serra do Esbarrancado, Nov. 2004, Smidt 796 (holotype HUEFS);
Nov. 2005, Azevedo 253 (paratype HUEFS).
HABITAT. Rocky places in campo rupestre vegetation, between 1,000 - 1,400 m altitude,
summit of Serra do Esbarrancado, among rocks and Velloziaceae.
98
CONSERVATION SATATUS. Vulnerable (VU – D). Besides Prescottia mucugensis is
inside of a National Park, it is currently known to exist at only a single location, in a small
and restricted population.
ETYMOLOGY. In reference to the type locality, the municipality of Mucugê.
NOTES. Ongoing molecular analyses (Azevedo et al. in prep.) based on nuclear and
chloroplast DNA sequences show that Prescottia mucugensis forms a group with P. phleoides
(Fig. 2H) and P. leptostachya (Fig. 2G), being sister to the former.
Prescottia leptostachya, like P. mucugensis, occurs in the campos rupestres of the
Chapada Diamantina, whereas P. phleoides grows on sandy soils in campos de altitude (high
altitude grasslands) in Southeastern Brazil, in elevations between 1,800 – 2,000 m.
Prescottia mucugensis can be distinguished from these taxa by the shape of its
inflorescence, floral bracts and flowers. Prescottia phleoides has multiflorous and congested
inflorescence, with the rachis 2.5 – 5.5 (7) cm long (Fig. 2H), while in P. leptostachya and P.
mucugensis the inflorescences are sparsely flowered. In Prescottia leptostachya the
inflorescence is really laxly flowered and the rachis is 8 - 20 (25) cm long (Fig. 2G).
Prescottia mucugensis can be distinguished from both these species by its angular rachis
shape (Fig. 1-2B), while in the other two it is cylindrical.
Prescottia phleoides differs by possessing long floral bracts, longer than the ovary and
flower combined, whereas in P. mucugensis the bracts are about the same length as the ovary
and flower together. Prescottia leptostachya bears shorter flower bracts, about the same
length as the ovary (Fig. 2G).
In addition to these differences, the lateral sepals are reflexed (with the distal part
adpressed to the ovary) in P. leptostachya, whereas in P. mucugensis (Fig. 2C-D) and P.
phleoides (Fig. 2H) the lateral sepals are adpressed to the lip. Prescottia mucugensis has small
flowers with the lip from 1.2 – 1.5 mm long, while P. leptostachya and P. phleoides present
99
bigger flowers with the lip between 2.5 – 3.5 mm long, and 2.5 – 4 mm long, respectively.
Prescottia leptostachya and P. phleoides have pale green sepals and petals with a green lip.
Prescottia mucugensis on the other hand has greenish to purplish brown sepals and petals and
a whitish to yellowish lip.
The following artificial key summarizes the most useful characters to separate the three
species:
1. Inflorescence congested, rachis 2.5 – 5.5 (7) cm long; floral bract longer than flower
....................................................................................................... Prescottia phleoides
1’. Inflorescence lax, rachis 3 – 20 (25) cm long; floral bract not longer than flower
..................................................................................................................................... 2
2. Rachis angular, 3 – 5.5 cm long; floral bract about the same length as flower ;
lateral sepals adpressed to the lip; sepals and petals greenish to purplish brown, and a
whitish to yellowish lip; lip 1.2 – 1.5 mm long ................. Prescottia mucugensis
2’. Rachis cylindrical, 8 - 20 (25) cm long; floral bract shorter then flower, about the
same length as the ovary; lateral sepals reflexed (with distal part adpressed to ovary);
sepals and petals pale green with green lip; lip 2.5 – 3.5 mm long ..........................

Introdução
2
3
Prescottia Lindl. é um gênero Neotropical de Orchidaceae que ocorre da Flórida ao
4
nordeste da Argentina, com grande riqueza de espécies no Brasil (Ackerman 2003). São ervas
5
terrestres, raramente epífitas, com folhas em roseta basal e inflorescência terminal. As flores
6
são pequenas, brancas ou branco-rosadas a esverdeadas, não ressupinadas, com labelo
7
cuculado.
8
Cogniaux (1895) descreveu Prescottia glazioviana com base em dois síntipos
9
coletados no estado do Rio de Janeiro: Glaziou 6729 (Protólogo: “Habitat ad cacumen mont.
10
Itatiaia in Campo de Silvério prov. Rio de Janeiro: Glaziou n. 6729 in herb. Berol. non alior”)
11
e Gardner 5884 (Protólogo: “Serra dos Órgãos: Gardner 5884 in herb. Berol. et Kew”). Nem
12
um dos dois espécimes citados para o herbário de Berlin (B) foi encontrado, o que significa
13
que provavelmente foram destruídos durante a Segunda Guerra Mundial. Do segundo foram
14
encontrados seis espécimes e, embora citado apenas para B e K, há exemplares também em
15
BM e R. Em K foram encontrados três espécimes. Desta forma, um dos espécimes de
16
Gardner 5884 foi recentemente selecionado como lectótipo (Azevedo & Van den Berg 2007).
17
Existe ainda um espécime em G: este apresenta data diferente de todos os outros e por isso
18
não foi considerado como isolectótipo.
19
Auguste François Marie Glaziou, botânico francês, coletou no Brasil entre 1861 e
20
1895 (Stafleu & Cowan 1976), sendo a região do Planalto do Itatiaia alvo de inúmeras
21
expedições botânicas desde 1872 (Brade, 1956). Em julho deste ano, Glaziou, acompanhado
22
da princesa Isabel, foi o primeiro a alcançar a parte mais alta do maciço. Nessa expedição,
23
várias espécies novas foram coletadas e descritas por especialistas da época. Ainda no século
24
XIX, a região recebeu os botânicos Wawra e Ule, e, no início do século XX, foi explorada
25
pelos botânicos Brade, Dusén, Tamandaré de Toledo Jr., Sampaio e Campos Porto, gerando
26
importantes contribuições ao conhecimento da flora regional. Alexandre Curt Brade,
27
pesquisador do Jardim Botânico do Rio de Janeiro, coletou continuamente no planalto por
28
mais de 30 anos (Brade, 1956).
29
Prescottia glazioviana é uma espécie rara e pouco conhecida. É aqui registrada pela
30
primeira vez para o estado de Minas Gerais. O ápice do labelo é proeminente, de margem
31
ondulada e constrição na região apical, característica encontrada apenas nesta espécie. Apesar
32
disso, essa informação não foi mencionada na descrição original (Cogniaux 1895), e a única
33
ilustração publicada da espécie (Hoehne 1945) também omite esta característica. Desta forma,
110
1
pretende-se aqui, além de registrar a ocorrência desta espécie para o estado de Minas Gerais,
2
apresentar uma descrição morfológica mais completa, com o intuito de elucidar questões
3
taxonômicas, e ilustrar estes caracteres.

14
indicados com asteriscos, sendo os materiais dos restantes obtidos através de empréstimos
15
para os herbários HUEFS, K e NY.
16
Expedições às áreas de ocorrência da espécie foram feitas no intuito de recoletar o
17
material. Destas, três foram realizadas para o estado do Rio de Janeiro, nas localidades tipo,
18
sendo duas para o Itatiaia (julho/2006 e abril/2007) e uma para a região da Serra dos Órgãos
19
(junho/2006). Para o Caparaó, no estado de Minas Gerais, foram realizadas sete expedições
20
(dezembro de 2007, janeiro, fevereiro, março e abril de 2008, fevereiro e abril de 2009), mas
21
não foi encontrado material além dos presentes nos herbários.

Habitat - Tanto no Rio de Janeiro como em Minas Gerais, Prescottia glazioviana habita
22
campos de altitude entre 1.790 – 2.400 m. No Parque Nacional do Caparaó, ela cresce sobre
23
afloramentos rochosos de gnaise que se apresentam revestidos por uma fina camada de solo
24
pétreo arenoso em meio a briófitas.
25
Status de Conservação - VU D2 (vulnerável) - Prescottia glazioviana é uma espécie rara, até
26
o momento conhecida por cinco coletas de apenas três ou quatro localidades (Itatiaia, Serra
27
dos Órgãos, Castelos (Serra dos Órgãos) e Alto Caparaó).
28
A primeira coleta de Prescottia glazioviana foi em 1841, na Serra dos Órgãos
29
(Gardner 5884). Supõe-se que a segunda coleta, do outro síntipo (Glaziou 6729), ocorreu em
30
1872. Embora o material tenha sido destruído, sabe-se que este foi o período em que Glaziou
31
realizou excursão à parte alta do maciço de Itatiaia (Brade 1956). Apesar das coletas de longo
32
prazo realizadas por Brade na região, não existe registro de que a espécie tenha sido coletada
33
novamente nesta área. Este último espécime (Glaziou 6729) coletado há 137 anos atrás é,
112

desta maneira, a primeira e única coleta realizada na região de Itatiaia. Entretanto, é preciso

cautela ao afirmar que a espécie de fato existe - ou existiu - no planalto do Itatiaia. Wurdack
3
(1970) chama atenção para a alteração dos locais de coleta e para a apropriação indevida de
4
materiais coletados por outros coletores por parte de Glaziou, sendo que a falta de coleta por
5
parte de Brade aumenta a desconfiança com relação à presença da espécie na região. A
6
terceira coleta, realizada na Serra dos Órgãos (Brade 11799 em 1932), 91 anos após a
7
primeira coleta nesta região (Gardner 5884 em 1841), foi também a última vez que a planta
8
foi encontrada no estado do Rio de Janeiro. A quarta coleta foi feita 66 anos depois, em Minas
9
Gerais (Souza et al. 2137 em 1998) e a quinta, alguns anos depois (Leoni 5280 em 2003), no
10
mesmo local da anterior.
11
Etimologia - O nome é em homenagem a Auguste François Marie Glaziou (1828-1906),
12
coletor de um dos síntipos da espécie.
13
Notas - Prescottia glazioviana é uma espécie pouco conhecida, embora seja facilmente
14
reconhecida por apresentar geralmente uma única folha com pecíolo curto, lâmina elíptica a
15
oblonga, o ápice das pétalas truncado e, principalmente, por apresentar o ápice do labelo
16
proeminente com margem ondulada e constrito na região apical, duas características
17
exclusivas desta espécie no gênero.
18
Prescottia glazioviana provavelmente ocorre no estado do Espírito Santo, uma vez que
19
o Parque Nacional do Caparaó situa-se na divisa dos estados de Minas Gerais e Espírito
20
Santo, sendo que 75% de sua área pertence ao Espírito Santo, mas aparentemente nenhuma
21
coleta foi feita neste estado. Embora tenha sido citada por Pabst & Dungs (1975) para São
22
Paulo, nenhum material coletado no estado foi encontrado, nem mesmo no Herbário
23
Bradeanum (HB) onde Pabst trabalhou e foi diretor.
24
Os espécimes coletados em Minas Gerais (Souza et al. 2137 e Leoni 5280) foram
25
encontrados entre o material indeterminado da família Orchidaceae. Após sua identificação
26
diversas excursões foram feitas à área no intuito de recoletar o material, que não foi
27
encontrado. A espécie em questão parece ser realmente muito rara. Trabalhos de campo mais
28
extensos serão necessários para afirmar com segurança o estado de conservação da espécie no
29
estado do Rio de Janeiro e sua real distribuição geográfica no território brasileiro.

Abstract
A taxonomic revision of Prescottia Lindl. (Orchidaceae: Orchidoideae), a
neotropical genus of mainly terrestrial orchids, is presented. This study is based on
fieldwork collection, in situ population observation, and herbaria collections
examination. Nomenclatural questions are analyzed, and ecological comments are
presented. Fifteen species are recognised for Prescottia in this study, incuding two
new described species (Prescottia mucugensis C.O. Azevedo & Van den Berg and
P. ecuadorensis C.O. Azevedo & Van den Berg). Two species complexes are
indicated. Eleven lectotypifications, one neotipification, and 11 new synonymies are
proposed. One sepecies is reestablished and four nomina nuda are detected. Macro
and micro-morphological data are given, besides species descriptions and
identification key. Each species is illustrated, relevant literature reviewed, and their
distribution mapped.

Introduction
Orchidaceae is one of the largest families of flowering plants, comprising
around 20.000 species and 850 genera (Atwood 1986; Dressler 1993), being widely
distributed but with the greatest diversity in the tropics. The family is monophyletic
and positioned as sister to the other members of the order Asparagales (Fay et al.
2000; Judd et al. 2007).
Tribe Cranichideae has been placed under different names in the subfamilies
Neottioideae (Lindley 1840a; Bentham 1881; Schlechter 1926; Garay 1960; Dressler
1974) and Spiranthoideae (Dressler 1979, 1981, 1990, 1993; Szlachetko 1995).
However, recent morphological and molecular phylogenetic studies have provided
evidence for their inclusion into an expanded concept of Orchidoideae (Dressler
1986; Dressler & Chase 1995; Kores et al. 1997, 2000, 2001; Cameron & Chase
1999; Freudenstein & Rasmussen 1999; Freudenstein et al. 2000).
Cranichideae sensu Dressler (1993) includes about 95 genera and 1.140
species of mainly terrestrial orchids, distributed in all continents, but are especially
diverse in the tropical and subtropical regions of America and Asia (Dressler 1993).
Dressler (1993) recognized six subtribes in Cranichideae, which agreed with subtribal
limits set previously by Schlechter (1926) except for the recognition of a new
subtribe, Prescottiinae (Dressler 1990), to accommodate several genera formerly
included in Cranichidinae. Subtribes Goodyerinae and Spiranthinae are both
widespread, whereas Cranichidinae and Prescottiinae are restricted to the
Neotropics, and Manniellinae and Pachyplectroninae are endemic to tropical Africa
and New Caledonia, respectively. Subtribe Prescottiinae sensu Dressler (1993)
contain 99 species, belonging to seven genera: Aa Rchb. f., Altensteinia Kunth,
Gomphichis Lindl., Myrosmodes Rchb. f., Porphyrostachys Rchb. f., Prescottia Lindl.,
and Stenoptera C. Presl. Except for Prescottia all others genera occur at higher
elevations in the Andes.
In 1824 Lindley described Prescottia, based on Prescottia plantaginifolia
(Lindley in Hooker 1824). Latter two species, originally described as Cranichis, C.
stachyodes Sw. and C. oligantha Sw. (Swartz 1788), were transferred to this genus
by Lindley (1836; 1840a). Cogniaux (1895), at Flora Brasiliensis, cited 19 species of
Prescottia to Brazil, however he did not comment anything about the non Brazilian
120
species previously described (P. ophioglossoides Spreng., P. petiolaris Lindl., P.
oligantha (Sw.) Lindl., P. tenuis Lindl., P. lanceaefolia Link & Otto ex Steud., P.
pachyrhiza A. Rich. & Galeotti, P. orchioides Lindl., P. lindeniana A. Rich. & Galeotti,
P. galeottii Rchb. f., P. cordifolia Rchb. f., P. pellucida Lindl., and P. myosurus Rchb.
f. ex Griseb.). Although he synonymized the Brazilian species Prescottia colorans
Lindl. and P. longipetiolata Barb. Rodr., under P. stachyodes (Sw.) Lindl., from
Jamaica.
At Flora Brasilica, Hoehne (1945), cited 17 species occurring in Brazil,
together with some non-Brazilian species, that he believed could be found in Brazil
as well (Prescottia longifolia Schltr., P. smithii Schltr., P. panamensis Schltr., P.
filiformis Schltr., and P. gracilis Schltr.). In addition, he created a new name (nomen
novum): Prescottia schlechteri Hoehne, for the Ecuadorian species Prescottia
longipetiolata Schltr (non P. longipetiolata Barb. Rodr.). Hoehne (1945) did not
mention anything about the varieties, nor about Prescottia tubulosa (Lindl.) L.O.
Williams. Once again, the author did not make any comments about the species
described before Cogniaux’s work, except for Prescottia lanceaefolia Link & Otto ex
Steud., which he considered a synonym of P. lancifolia Lindl.
In 1975, Pabst & Dungs listed 17 species of Prescottia native to Brazil, and
established four informal groups for the Brazilian species of the genera: Prescottia
colorans alliance: lip internally glabrous, leaves elliptic, clearly petiolate; Prescottia
plantaginea alliance: lip internally glabrous, leaves lanceolate and indistinctly
petiolate; Prescottia oligantha alliance: lip internally densely pilose, leaves elliptic or
oval; and Prescottia lancifolia alliance: lip internally densely pilose, leaves lanceolate.
In recent years, Prescottia has been treated in the context of regional floras,
without any attempt to evaluate previous taxonomic views. Available treatments of
Prescottia within country boundaries are the following: Barbosa-Rodrigues (1882 Brazil), Cogniaux (1895 - Brazil), Cogniaux (1907 - Brazil), Fawcett & Rendle (1910 Jamaica), Gale & Baldomero (1938 - Cuba), Hoehne (1945 - Brazil), Williams (1946 Panama), Williams (1951 - Mexico), Hodge (1953 - Dominica, British West Indies),
Schweinfurth (1958 - Peru), Dunsterville & Garay (1959 - Venezuela), Britton &
Millspaugh (1962 - Bahama), Correll (1965 - Guatemala and British Honduras),
Dunsterville & Garay (1965), Dunsterville & Garay (1966 - Venezuela), Schweinfurth
(1967 - Guayana), Adams (1972 - Jamaica), Garay & Sweet (1974 - Lesser Antilles),
121
Hamer (1974 – El Salvador), Pabst & Dungs (1975 - Brazil), Garay (1978 - Ecuador),
Hamer (1984 - Nicaragua), Hamer (1985 - Nicaragua), McVaugh (1985), Werkhoven
(1986 - Suriname), Ackerman (1989 - Puerto Rico and the Virgin Islands), Cremers &
Hoff (1992 - French Guiana), Ackerman (1995 - Puerto Rico and the Virgin Islands),

Christenson (1998 - Peru), Serna & Ferrari (1998), Jørgensen & León-Yánez (1999 Ecuador), Balick et al. (2000 - Belize), Carnevali & Romero (2000 - Venezuela), Dix
& Dix (2000 - Guatemala), Carnevali et al. (2001 - Yucatan Peninsula, Mexico),
Feldmann & Barré (2001 - Guadeloupe), Stevens et al. (2001 - Nicaragua), Carnevali
et al. (2003), Hammel et al. (2003 – Costa Rica), and Ackerman (In press - Greater
Antilles).
The original publication of the genus spelled it as “Prescotia”. Since then and
until recently, the name was spelled double “t”, including subsequent writings of
Lindley himself. Azevedo & van den Berg (2005) proposed the conservation of the
two "t" spelling due to its common usage; the proposal has been approved (Brummitt
2007).
Prescottia Lindl., as here circumscribed, is a Neotropical genus comprising at
least 15 species of delicate to robust herbaceous, terrestrial or epiphytic plants,
extending from Florida (U.S.A.) through the West Indies to northeastern Argentina,
with the greatest diversity in Brazil. They inhabit mainly humid forests, usually in very
small populations. The genus presents rather variable morphological characters, and
species of difficult delimitation, for that reason many new species were described and
later became synonyms.
This study aim to provide a taxonomic revision of Prescottia, based on macroand micro-morphological data, presenting an identification key, descriptions,
illustrations, coments and discussion about morphological and taxonomic aspects,
besides providing geographic distribution data and maps for each species.
Materials and Methods
A bibliographic revision was carried out by surveying the general and classic
literature, mainly in the Library of the Royal Botanic Gardens - Kew and the New
York Botanical Garden, but also at the Botanische Staatssammlung München -
122
Munich, Muséum National d'Histoire Naturelle - Paris, The Natural History Museum London, and Naturhistorisches Museum Wien - Vienna.
Field studies. Many individuals of Prescottia were observed in Brazil (States of
Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, and São Paulo) and Costa Rica
in their natural habitats. Specimens were fixed in 70% ethanol. Ecological conditions
were registered during field work. These observations were important for expanding
information on character variation within and among populations of the genus.
Herbarium studies. Around 2.000 herbarium specimens from 82 herbaria were
examined. These included specimens from the following herbaria: AAU, ALCB*,
AMES, B, BAH, BBG, BHCB*, BM*, CAY, CEN, CEPEC*, CESJ, CGMS, CM, COL,
COR, CR*, CTES, CVRD, EAC, ESA*, ESAL, F, G, GFJP, GH, GUA, HAS, HASU,
HB*, HEPH, HMS, HRB*, HRCB, HUA, HUFU, HUEFS*, HURG, HXBH, IAC, IBGE,
ICN, INPA, IPA, JPB, K*, K–L*, LP, M*, MAC, MBM*, MBML*, MG, MO, MVFA, MVM,
NY*, P*, PACA, PAMG, PEL, PEUFR, PMSP, QCNE, R*, RB*, RBR, RPSC, RUSU,
S, SEL, SJRP, SMDB, SP*, SPF*, TEPB, UB, UEC*, UFMT, US, USJ*, VEN, VIC,
W* (acronyms according to Holmgren & Holmgren 1998). Specimens were studied
by visiting some of the herbaria (herbarium acronyms indicated with asterisk were
visited) or as loans to the Herbaria HUEFS, K and NY.
Databases. Voucher specimen informations were inserted in an Access database.
Taxonomic descriptions were created using the DELTA software package
(Description Language for Taxonomy).
Maps. Latitude and longitude attributes were gathered from the labels of herbarium
vouchers examined. Missing coordinate data from voucher specimens were assigned
after consulting geographic sites available on-line or maps (e.g. Google Earth).
Distribution maps for each taxon were prepared with ArcGis (Environmental Systems
Research Institute (ESRI) 2003). Maps were based on herbarium specimens
examined.
123
Descriptions. The dichotomous key proposed is artificial and therefore does not
intend to reflect evolutionary relationships. Species are listed alphabetically by
specific epithet. All specimens studied are cited in the list of specimens. Numeric
values are given in their normal ranges, with extreme values enclosed in
parentheses. Description of habit, color and information on distribution and ecology
were gathered from herbarium specimen labels and field observations. Illustrations
were made under stereoscopic microscope with a drawing tube, from fresh or
herbarium material.
Typification. Lectotypes were designated from the extant isotype(s) or syntype(s)
whenever appropiate. For a number of species no types were located, but line
drawings, published or not, based on type specimen were consulted, and selected as
lectotypes. For each case, the International Code of Botanical Nomenclature (McNeill
et al. 2006) was considered to make the appropriated decision.
Laboratory studies. A combination of stereoscopic microscope and scanning
electron microscopy (SEM) studies were conducted to investigate and document
both vegetative and reproductive features of Prescottia.
Micromorphology. For SEM study the flowers were dissected under a stereoscopic
microscope, and the isolated parts processed for SEM. Different floral segments from
dried and preserved specimens were dehydrated in an ethanol series, and critical
point dehydration. Small pieces of different floral parts (e.g. gynostemia and lip) were
mounted on stubs and gold sputter coated for SEM study, and examined under a
LEO 1430 VP - Carl Zeiss scanning electron microscope. SEM studies on pollen and
pollinaria were made using a non-acetolytic method to avoid destruction. Seeds from
naturally dehiscing capsules taken from dried specimens were examined under SEM
microscope. Images of the structures obtained under the SEM and light microscopes
were recorded digitally. Measurements were taken directly from the digital images.
MORPHOLOGY
Habit. Plants of Prescottia are primarily terrestrial, occasionally epiphytic, perennial
herbs. They are quite diverse in height. Some are not taller than 2.5 – 6.5 cm,
124
whereas others are nearly 1 m tall (including the inflorescence). The smallest species
is P. ostenii. In contrast, the tallest representatives are P. spiranthophylla and P.
stachyodes.
Habitat. Most Prescottia species are adapted to the warm, rainy, and humid
conditions of tropical rainforests. Some also occur in secondary zones including
landsides and roadsides, and rocky places near mountain summits. Reaching
elevations between sea level and 3.700 m.
Roots. The roots of Prescottia are fasciculate, elongate, cylindrical to fusiform,
extremely thick and fleshy, and pale-brown in color, and possess an indument of
persistent root hairs, usually described as pubescent, pilose, or villose.
Stem. The stem is very short or inconspicuous and located below or on the substrate
surface. The roots and terminal inflorescences develop from it.
Leaves. The leaves are green, ranging from light to dark-green, darker and glossier
on the adaxial surface, sometimes white on the margin or with longitudinal stripes,
(variegate).They are basal, and usually form a rosette, and are soft, herbaceous to
coriaceous, sometimes fleshy, and glabrous. The leaves are exceedingly variable in
shape and length. The species have lanceolate, elliptic, oblong, or linear to obovate
leaves, blades up to 45 cm long, which are sessile or short to long petiolate. The
blades have entire or serrulate margin. The leaves may attain lengths of over 45 cm
and widths of 15 cm. There is a great variation in the length and width of leaves
throughout the genus and species.
Inflorescence. The inflorescence is terminal, long- or short-pedunculate and
glabrous. The inflorescence is densely many-flowered or loosely few-flowered, short
or long spike, and ranges from erect to pendulous. Prescottia spiranthophylla and P.
stachyodes exhibits the longest inflorescences in the genus, whereas P. ostenii
produces the shortest ones.
125
Flowers. The flowers of Prescottia are hermaphroditic, small, non-resupinate, spirally
arranged, each one subtended by a bract. Flower opening starts from the base to the
apex (acropetal). Their predominant colours are green, white, and yellow. The floral
bracts are ovate or lanceolate, with acute to acuminate apex. They are clasping to
the base of the ovary, and are shorter or longer than the flowers. Sepals are basally
connate and form a short cup. They are erect to reflexed or revolute. Petals are
variable in shape, but usually ovate or linear and free, erect to reflexed or revolute.
The lip is simple with entire margins, hood-shaped or cucullate [e.g. P. oligantha
(Azevedo 329) and P. phleoides (Azevedo 344) Fig. 1 A-B], rare with a prominent
and ondulate margin [P. glazioviana (Leoni 5280) Fig. 1 C-D]. It has nectariferous
glands at its base [e.g. P. phleoides (Azevedo 344) and P. ostenii (Singer 2006/21)
Fig. 1.E-F]. The lip inner surface is glabrous [e.g. P. mucugensis (Azevedo 253) Fig.
1 G; P. glazioviana (Leoni 5280) Fig. 1 H; P. stachyodes (Azevedo 288) Fig. 2 A-B]
or pilose [e.g. P. densiflora (van den Berg 1417) Fig. 2 C-D; P. lancifolia (Bocayuva
198) Fig. 2E-F; P. oligantha (Azevedo 329) Fig 2 G-H; P. ostenii (Singer 2006/21)
Fig. 3 A-B]. The outer surface is smooth or densely minute-papillose [e.g. P.
spiranthophylla (Azevedo 270) Fig. 3 C-D], glabrous or with trichomes at the base
[e.g. P. plantaginifolia (Azevedo 263) Fig. 3 E; P. spiranthophylla (Azevedo 270) Fig.
3 F].
Gynostemium. The column or gynostemium is erect, blunt, and short. The dorsal
surface of the column is glabrous [e.g. P. phleoides (Azevedo 344) and P. ostenii
(Singer 2006/21) Fig. 3 G-H] or covered by trichomes [e.g. P. plantaginifolia
(Azevedo 263) Fig. 4 A-B; P. spiranthophylla (Azevedo 270) Fig. 4 C-D]. Column foot
is absent. The anther is erect, motile, ovate to oblong, opening laterally to the center
of the flower, and two-locular. The anther is parallel to the axis of the column, firmly
attached to a short, thick filament [e.g. P. leptostachya (Azevedo 250) and P.
stachyodes (Azevedo 288) Fig. 4 E-F]. The rostellum is laminar and thin. The stigma
is horizontal, relatively small, ovate, and flat to convex [e.g. P. densiflora (van den
Berg 1417) Fig. 4 G; P. oligantha (Azevedo 329) Fig. 4 H; P. plantaginifolia (Azevedo
263) Fig. 5 A; P. phleoides (Azevedo 344) Fig. 5 B; P. montana (Azevedo 324) Fig. 5
C; P. stachyodes (Azevedo 288) Fig. 5 D]. The hamulus is absent. There are two
appendages on the column apex [e.g. P. oligantha (Azevedo 329) Fig. 5 E-F; P.
126
montana (Azevedo 324) Fig. 5 G; P. phleoides (Azevedo 344) Fig. 5 H], which can
be wide or reduced, and could be interpreted as staminodes (Kurzweil 1988).
Pollinaria and Pollen
The pollinia are four (two-bipartite), oblong-ovoid, powdery or soft, without
caudicles, and yellow in color [e.g. P. oligantha (Azevedo 329) Fig. 6 A]. They are
adnate to a single terminal brown viscidium [e.g. P. oligantha (Azevedo 329) Fig. 6 B;
P. phleoides (Azevedo 344) Fig. 6 C-D], which is small, detachable, oval, and very
sticky.
The pollen grains are arranged in tetrads [e.g. P. oligantha (Azevedo 329) Fig.
6 E; P. phleoides (Azevedo 344) Fig. 6 F], elastoviscine was observed between
tetrads [e.g. P. densiflora (van den Berg 1417) Fig. 6 G; P. phleoides (Azevedo 344)
Fig. 6 H, 7 A-B], as showed by Schill & Wolter (1986) and by Burns-Balogh (1987) to
Prescottia stachyodes. The pollen has reticulate exine, with smooth walls [e.g. P.
phleoides (Azevedo 344) and P. stachyodes (Azevedo 288) Fig. 7 C-D], similarly
documented by Schill & Pfeiffer (1977) to Prescottia plantaginifolia. Germinated
pollen was observed in the anther cavity [e.g. P. stachyodes (Azevedo 288) Fig. 7 EF].
Ovary. The ovary is unilocular, usually ovoid, with three longitudinal ridges
externally. The single locule contains numerous small ovules and the placentation is
parietal. The pedicel is absent.
Fruits. The fruits are capsules, bearing the persistent remnants of the floral
segments. Young fruits are light green, whereas mature fruits are medium to dark
brown.
Seeds. Seeds of this genus are diverse and lack distinctive generic characters. They
are very small, and dust-like in appearance. They are usually fusiform, golden brown,
ranging from 270 – 950 µm, with about three to nine cells in wide, and are covered by
a smooth seed coat that surrounds a minute embryo.
The species studied here are represented by oblong to linear seeds, some
have no intercellular spaces, in others triangular intercellular spaces are found at the
127
angles of the testa cells, or circular intercellular spaces around the testa cells are
present. That can be observed in Prescottia carnosa [Fig. 8 A-B (Steyermark

3758)], P. leptostachya [Fig. 8 G-H (CFCR 7308)], P. lojana [Fig. 9 A-B (Holst 3522)],

plantaginifolia [Fig. 10 C-D (Mori 10702)], and P. spiranthophylla [Fig. 10 E-F
(Mulford 881)].
In Prescottia stachyodes its anticlinal walls of the testa cells are more or less
partly splitted forming a series of small fusiform intercellular spaces with beaded
appearance (Fig. 10 G-H, 11 A-H). The length of the seeds varies between
specimens, but in width there is no marked difference. It differs from all species of the
genus. Different morphs from different locations were examined. From Brazil, three
different size samples were scanned, an intermediate size from Rio de Janeiro [Fig.
10 G-H (Azevedo 318)], a taller one from São Paulo [Fig. 11 C-D (Kuhlmann 2742)],
and a smaller from Espírito Santo [Fig. 11 E-F (Oliveira 842)]. Samples of different
size from Jamaica were observed, a morph as “P. pellucida Lindl.” [Fig. 11 A-B
(Harris 10096)], and another as “P. cordifolia Rchb. f.” [data not shown (Maxon 943)].
A small specimen from Mexico was seen [Fig. 11 G-H (Raven 19994)]. A type of “P.
petiolaris” (Callejas 9672) from Colombia, a sample from Venezuela (Steyermark
103947) and another from Ecuador (Alvarez 2862) were also observed (data not
shown).
Cytogenetics
The chromosomes in Prescottia are small, variable in number (n = 48 or 2n =
48) and homogeneous or not in size. Some species (P. leptostachya and P.
stachyodes) has a bimodal karyotype, with one pair of chromosomes significantly
larger than the rest (Felix & Guerra 2005). Felix & Guerra (2005) suggested a strong
affinity between the subtribes Prescottiinae, Spiranthinae, and Cranichidinae,
because the three share the bimodal chromosome size associated with the basic
numbers x = 23, 24.
Ecology
128
Species of the genus are remarkable for their broad ecological tolerance and
phenotypic plasticity (Ackerman 2000). The genus has been noted as growing in the
understory of moist and wet montane forests at low to high elevations, from sea level
to 3.700 meters. Most plants occur in the shade of shrubs. Flowering and fruiting
specimens have been collected the whole year.
Reproductive biology
Ackerman (2003) suggested that some Central American species of Prescottia
were autogamous. Singer & Cocucci (1999) reported that Prescottia densiflora
(Brongn.) Lindl. is pollinated by halictid bees (Halictidae). The pollinaria are
deposited on the bees proboscis while probing the flowers for nectar, and are
removed when the insect leaves the flower, visiting another flower it will brush the
stigmatic surface and leave clumps of pollen. Flies of the family Syrphidae are
secondary pollinators. Posteriorly, Singer & Sazima (2001) verified that P. densiflora,
P. stachyodes (Sw.) Lindl. and P. plantaginifolia Lindl. ex Hook. are self-compatible
but pollinator-dependent. Pollination by halictid bees was confirmed for P. densiflora
and moth-pollination was registered for P. stachyodes and P. plantaginifolia. Besides
that, protandry was reported for P. stachyodes and P. montana Barb. Rodr. (Singer &
Sazima 2001).

HABITAT. Occur in grasslands on summit plateaus, at elevations between 1.400 and
2.300 m.
145
CONSERVATION STATUS. Vulnerable (VU – D2). This taxon is known to exist at no
more than five locations, represented only from four herbarium collections (see
above).
ETYMOLOGY. From the Latin carnosus (= fleshy), probablly a reference to the very
fleshy lip.
NOTES. Prescottia carnosa is poorly known and rarely collected. No sample of this
species was included for the molecular studies (Chapter 2), but this taxa might be
expected to form a sister relationship with P. stachyodes (Sw.) Lindl., because it also
have long petiolate leaves, flowers with the inner surface of the lip glabrous.
Prescottia carnosa is distinguished from all other species of the genus by the
longitudinal keel or septum in the center of the fleshy lip. Another remarkable
character of this taxon is the flower position, which is almost patent.

HABITAT. Prescottia densiflora is light-tolerant and occurs in humid, though welldrained soils in open areas.
CONSERVATION STATUS. Not endangered.
ETYMOLOGY. Probablly a reference to the dense inflorescence, with many flower
and very congest. From the Latin densus = congest, and flora or flos = flower.
NOTES. Prescottia densiflora is characterized by elliptic leaves, sessile to
pseudopetiolate, and lip internally pilose. Morphologically, Prescottia densiflora is
very similar to P. oligantha. Otherwise Wiggins & Porter (1971) considered it as
synonym of P. oligantha. The morphological extremes are well delimited, but
intermediate specimens make the delimitation among them very hard. The type of
150
Prescottia densiflora is a morphological extreme, and can be easily distinguished by
its sessile leaves and congest inflorescence. Phylogenetically it is close related to the
others species of whitish flowers and lip internally pilose (P. lancifolia, P. oligantha,
and P. ostenii), being more closely related with P. lancifolia and P. ostenii (Chapter
1).
The IPNI cites that the new combination of Decaisnea densiflora was made at
1841, but the number 34 of the “Annals and Magazine of Natural History” was
published in 1840 (Lindley 1840b). The latter and “The genera and species of
orchidaceous plants” (Lindley 1840a) were published in September 1840, but the
second one, already cites Prescottia densiflora (Brongn.) Lindl., as published at
Annals and Magazine of Natural History (Lindley 1840b), for this reason, we believe
that the combination was published on it.
There are two type specimens of Decaisnea densiflora, one at P and another
at K-L, both annotated with the same information given in the protologue. When
Lindley (1840b) transferred D. densiflora to Prescottia, he said that Brongniart gave a
specimen to him. The specimen given to Lindley has the original illustration, and was
designated as the lectotype of D. densiflora by Azevedo & van den Berg (2007a).

walking from centro de Information. 21/11/1989, Madsen, J.E. 86457, holotype,
Prescottia ecuadorensis C.O. Azevedo & Van den Berg. (MO).
HABITAT. Ridge top vegetation of elfin forest and paramos, between elevations of
3.000 - 3.400 m.
CONSERVATION STATUS. Vulnerable (VU – D2). It is known to exist at only a
single location, represented by only a single specimen.
ETYMOLOGY. In reference to the country where the type specimen was collected.
NOTES. There are two specimen of Madsen & Pedersen 86457, one at MO (Fig. 4),
and the other at AAU, which are different, the one in AAU is a specimen of Prescottia
lojana, and it was cited at the P. lojana’s original description (Dodson 1996) as other
specimen seen, however only the AAU material was cited in the protologue. Although
154
the MO material is determinate by Dodson, we believe he did not saw it. First
because he did not cite it at the P. lojana’s protologue, and second, because it has
not his handwriting determination, as at AAU. It means that the MO material could be
identified as P. lojana only because it is a duplicate of the AAU material, cited at the
P. lojana’s protologue.
This species was not available for the molecular studies, although, it appears
to be related to Prescottia carnosa, P. lojana and P. stachyodes. Morphologically
Prescottia ecuadorensis is most closely related with P. lojana Dodson, P. carnosa
and P. stachyodes (Sw.) Lindl. Prescottia ecuadorensis can be distinguished from
these taxa by its leaves, inflorescence, and flowers. Prescottia ecuadorensis can be
also distinguished from these by its seeds. Prescottia carnosa presents oblong seeds
with triangular intercellular spaces at the angles of the testa cells [Fig. 16. 1-2
(Steyermark 59772)], while in P. lojana its intercellular spaces are circular, and
around the testa cells [Fig. 16. 3-4 (Holst 3522)]. Prescottia ecuadorensis seeds are
fusiform, without intercellular spaces [Fig. 16. 5-6 (Madsen & Pedersen 86457)],
whether P. stachyodes has linear seeds, its anticlinal walls of the testa cells are more
or less partly splitted forming a series of small fusiform intercellular spaces with
beaded appearance [Fig. 16. 7-8 (Harris 10096)].

HABITAT. In Rio de Janeiro and in Minas Gerais, Prescottia glazioviana grows on
sandy soils, in campos de altitude (high altitude grasslands), in elevations between
1.700 - 2.400 m.
CONSERVATION STATUS. Vulnerable (VU – D2) This taxon is known to exist at no
more than five locations. Prescottia glazioviana is known only from five herbarium
collections: the two sintypes, and three other collections (see above), from three or
four sites [Itatiaia, Serra dos Órgãos, Castelos (Serra dos Órgãos) and Alto
Caparaó]. It was first collected in 1841, at Serra dos Órgãos (Gardner 5884). The
second collection was probably that of 1872 (Glaziou 6729), when Glaziou made a
fieldtrip to Itatiaia (Brade 1956). Even though, Alexandre C. Brade collected
systematically, for more than 30 years, in Itatiaia (Brade 1956), P. glazioviana has
never been collected again at Itatiaia. This latter specimen (Glaziou 6729), collected
137 years ago, is therefore the first and only collection in the region. The third
collection at Serra dos Órgãos (Brade 11799 in 1932), 91 years after the first
collection in the region (Gardner 5884 in 1841), is also the least collection of the
species at the state of Rio de Janeiro. The fourth collection was made after 66 years,
in the state of Minas Gerais (Souza et al. 2137 in 1998) and the fifth, some years
after (Leoni 5280 in 2003), in the same place. During this study three fieldtrips were
undertaken to the two places at Rio de Janeiro, and seven to Minas Gerais, but the
species was not recollected.
ETYMOLOGY. The name honours Auguste François Marie Glaziou (1828-1906), a
French botanical traveller who collected in Brazil between 1861 and 1895, and was
director of the “Passeio Público”, Rio de Janeiro (Stafleu & Cowan 1976).
160
NOTES. Prescottia glazioviana is a rare and poorly known taxon, and was not
available for the molecular studies. Azevedo et al. (submitted a, Chapter 2) present a
complete morphological description and illustration, showing for the first time, several
diagnostic features lacking in the original description: e.g. the lip apex constricted
and with a prominent and ondulate margin. The species is also recognized by its
unusual truncate petal apex.
Pabst & Dungs (1975) cited it to São Paulo, although no specimen from this
state was found, even in the Herbarium Bradeanum (HB) where Pabst worked and
was director. Azevedo et al. (submitted a, Chapter 2) sugested that Prescottia
glazioviana may occur at Espírito Santo state, once it was found at Parque Nacional
do Caparaó, which comprises both states Minas Gerais and Espírito Santo, and 75%
of the park area is at the Espírito Santo. However no collection was made in this
state so far.
It is not easy to suppose the relationship among Prescottia glazioviana and
the others Prescottia species, because P. glazioviana presents a very distinctive lip,
which is unique in the genus. We would expected that it has a sister relationship with
the clade B (Chapter 1). Its leaves are more similar to the Prescottia leptostachya
(short petiole), although its flowers are more reminiscent of P. mucugensis and P.
phleoides.
Cogniaux (1895) described Prescottia glazioviana based on two syntypes,
both collected at Rio de Janeiro state: Glaziou 6729 and Gardner 5884. None of
them, assumed to be housed at B, was found there, probably destroyed during World
War II. From the second (Gardner 5884), six specimens were found, one of which
was selected as the lectotype of P. glazioviana by Azevedo & van den Berg (2007a).
There is a specimen at G with a different date (July 1842). Because the date is
different from the other specimens, it was not considered as an isolectotype
(Azevedo & Van den Berg 2007a).

HABITAT. Epiphytic in rainforest, between elevations from 400 to 1.700 m.
CONSERVATION STATUS. Not endangered.
ETYMOLOGY. Probably a reference to the lanceolate leaves.
NOTES. Prescottia lancifolia can be distinguished by its lanceolate leaves, nodding
inflorescence and lip internally pilose. Based on DNA sequence data, it is within the
whitish flowers and lip internally pilose clade. Prescottia lancifolia is sister to P.
ostenii (Chapter 1).
The relation between the length of the leaves and the inflorescences has been
the main reason, up to now, for the separation among Prescottia lancifolia, P.
166
epiphyta, and P. truncicola. The inflorescences can be shorter than the leaves, but
they are generally longer. These characters, therefore, appear to represent normal
variations within this species, even among specimens of the same collection and
population. This variation has been the reason for some confusion among these taxa.
For example: one of the syntypes of Prescottia truncicola (Dusén 10290) was cited
before its publications as Prescottia lancifolia by Kränzlin (1911).
Prescottia lancifolia was described based on two syntypes, Gardner 681 and
Descourtilz s.n. Seven specimens annotated as Gardner 681 were found. However,
the Descourtilz’s syntype was not found. Azevedo & van den Berg (2007a) selected
the syntype Gardner 681 housed in Lindley’s herbarium (K-L) as the lectotype of P.
lancifolia. When Schlechter described Prescottia truncicola he cited two syntypes,
Dusén 18154 and Dusén 10290. The original material of P. truncicola was probably
at B and destroyed during World War II. As there is no evidence that Schlechter had
examined the syntype at MBM, Azevedo & van den Berg (2007a) chose the AMES
syntype as the lectotype of this species, which is annotated in Schlechter’s
handwriting with the same information given in the protologue and determined by him
as P. truncicola.
When Barbosa-Rodrigues (1881) described Prescottia octopollinica, he stated
that this taxon was very similar to his P. epiphyta, differing only in the number of
pollinia. Prescottia octopollinica was characterized by the presence of eight pollinia.
Probably it is due to a confusion, because he justified the number of pollinia saying
that Lindley cited “pollinia 4 geminata”, and he observed that the species in question
had four very detached pollinia pairs that made it eight. Actually, when Lindley
described the genus he cited: “pollinia 2, didyma” (in Hooker 1824), confirming the
same information a few years later (Lindley 1840a): “pollinia 2, biloba”. Before in
1836 (Lindley 1836) he described the genus and stated: “pollinia 4, geminata” giving
rise to the confusion. Apparently, Barbosa-Rodrigues’ illustration shows four sulcate
pollinia. Eight pollinia were never found again indicating that it was only a
misinterpretation.
Barbosa Rodrigues’ herbarium specimens were lost after his death (Cribb &
Toscano-de-Brito 1996). After verifying the materials at the Herbarium of the Jardim
Botânico do Rio de Janeiro (Rio de Janeiro Botanical Garden), we chose to
167
lectotypify Prescottia epiphyta and P. octopollinica upon the plates mentioned by the
author in the original description, recently reproduced in Sprunger et al. (1996).

but we could not find any specimen from the later. In Bahia it is encountered at
Chapada Diamantina, where it was cited for Rio de Contas (Toscano de Brito 1995),
Lençóis (Toscano de Brito 1998), Catolés (Toscano de Brito & Queiroz 2003), and
Mucugê (Azevedo & van den Berg 2007b) and at “restinga” on the east coast. Map 4

HABITAT. It grows in sandy soils on dunes, or in the organic matter gathered
between the rocks, in campo rupestre vegetation, between elevations from sea level
to 1.700 m.
CONSERVATION STATUS. Not threatened.
NOTES. Prescottia leptostachya is characterized by the silver-green leaves with
entire margins, long inflorescence, rachis with 8-20 cm length, and small flowers.
Based on DNA sequence data, P. leptostachya is grouped in a clade with P.
mucugensis and P. phleoides (Chapter 2). However, morphologically P. leptostachya
flowers look like that of P. plantaginifolia, from which the former may be distinguished
by its leaves. Furthermore, P. plantaginifolia has the dorsal surface covered by
trichomes and P. leptostachya has it glabrous.
We have found six Salzmann’s specimens annotated as Prescottia
leptostachya in different herbaria: one at K-L, one at P, another at W, and two at K,
one stamped with “Herbarium Hookerianum 1867” and the other with “Herbarium
Benthamianum 1854”. The materials at K, K-L and W have the same handwriting
label informations, and corresponding exactly to the protologue of the species. The P
material is typewritten as “Bahia, Salzmann”. There is also a specimen at G,
annotated in Salzmann’s handwriting with almost the same information given in the
protologue: “Bahia, in fruticetis sabulosis aridis” and additional information indicating
the year (1831) and the collection number (536). However, as the latter has
informations about year and collection number, which are different from the other
specimens, we did not consider this specimen as an isotype. The holotype is the
172
specimen housed in Lindley’s herbarium, as Lindley is the author of the species; this
specimen has also a line drawing made by Lindley on it.

HABITAT. Prescottia lojana grows on eroded sandstone mesa with deep crevices
and large rock formation, mostly in shrub island or open forest, in elevations between
3.000 and 3.700 m.
CONSERVATION STATUS. Not Evaluated.
ETYMOLOGY: Named for the region of Loja (Dodson 1996).
NOTES: Prescottia lojana can be diagnosed by its fleshy to coriaceous leaves and lip
with prominent midvein. It was not available for the molecular studies, however, it
appears to be related to Prescottia carnosa, P. ecuadorensis, and P. stachyodes. All
of them have petiolate leaves, greenish flowers and the inner surface of the lip
glabrous.
The Orchidaceae of the Ecuadorian Herbarium Río Palenque Science Center
(RPSC) were transferred to MO, though the holotype is now at the Missouri Botanical
Garden herbarium (MO).

HABITAT. It grows on granitic substrates or on sandy soils, in campos de altitude
(high altitude grasslands) and campo rupestre vegetation, in elevations between 730
and 2.660 m.
CONSERVATION STATUS. Not endangered.
ETYMOLOGY. Probably named for the place where the species was collected at the
summit of a mountain.
NOTES. Prescottia montana is easily recognized by the dense and conical
inflorescence, by the presence of a single lanceolate leaf and yellow-greenish
flowers, with the lateral sepal adpressed to the lip.
Based on DNA sequence data, Prescottia montana is sister to P. stachyodes,
with which it shares some morphological similarities, as petiolate leaves. However, it
is more similar to P. phleoides, which has sessile to pseudopetiolate leaves. Both
share multiflowered, dense inflorescences and flowers with lateral sepals adpressed
to the lip.

2). Map 4 (p. 163).
BRAZIL, Bahia, Mucugê, Chapada Diamantina, Guiné, Serra do Esbarrancado,
11/2005, Azevedo, C. 253, paratype, Prescottia mucugensis (HUEFS); Mucugê,
Chapada Diamantina, Guiné, Serra do Esbarrancado, 11/2004, Smidt, E. 796,
holotype, Prescottia mucugensis (HUEFS).
HABITAT. It grows on rocky places at campo rupestre vegetation, between 1.000 1.400 m altitude, among Velloziaceae.
CONSERVATION STATUS. Vulnerable (VU – D2). Besides Prescottia mucugensis
is inside of a National Park, it is currently known to exist at only a single location, in a
small and restricted population.
ETYMOLOGY. A reference to the type locality, the municipality of Mucugê.
NOTES. Molecular analyses based on nuclear and chloroplast DNA sequences
(Chapter 1) suggest that Prescottia mucugensis is most closely related to P.
phleoides Lindl. and P. leptostachya, respectively.
184
Prescottia mucugensis can be distinguished morphologically from these two
taxa by its inflorescence and flowers. Prescottia phleoides has multiflorous and
congested inflorescences, while P. leptostachya and P. mucugensis have it more
loose. Prescottia mucugensis can be distinguished from these also by its angular
rachis shape, while in the other two it is cylindrical. Additionally, the lateral sepals are
reflexed (with distal part adpressed to the ovary) in P. leptostachya, whereas the
lateral sepals in P. mucugensis and P. phleoides are adpressed to the lip. Prescottia
leptostachya and P. phleoides have pale green sepals and petals with green lip.
Prescottia mucugensis has the sepals and petals greenish, with some brown, and a
whitish to yellowish lip.

HABITAT. Terrestrial in limestone rocks or soils under shady sites in moist and wet
forests, elevation from sea level to 2.900 m.
CONSERVATION STATUS. Not endangered. Although Prescottia oligantha was
cited at the list of endangered (EN) species of Florida (Ward et al. 2003) and at the
CITES Appendix II (2007), it is a well represented and widespread species, reason
why we are considering it as a not threatened species.
ETYMOLOGY. From the Greek oligo (few) and anthos (flower), but since this plant is
not few-flowered this epithet is confusing (McLeish et al. 1995).
NOTES. Prescottia oligantha has elliptic to lanceolate leaves, inflorescences loose,
with white flowers, and lip internally densely pilose. The size and form of these plants
are extremely variable, changing without any evident pattern. These characters are,
then, variable within this species. Prescottia oligantha is delimitated here in a more
extensive circumscription, as a result of the difficulty to establish the limits or
201
boundaries of the taxon. We are indicating here that it is probably a species complex,
and population studies would help to clarify and elucidate the real circumscription of
the species. Based on DNA sequence data, it is within the whitish flowers and lip
internally pilose clade (Chapter 1).
Cranichis oligantha was described by Swartz without information about type
specimen. Some authors cited the type for BM (Fawcett & Rendle 1910, Garay &
Sweet 1979, McLeish et al. 1995), while Garay (1978) indicated that it was at S. For
this reason, Azevedo & van den Berg (2007a) chosen the BM specimen as the
lectotype of C. oligantha. The specimen at BM bears an annotation on the back of
the sheet, which agrees in part with the protologue and especially with the later
citation of Swartz (1806). Sprengel renamed Cranichis oligantha as C. micrantha
because he felt that Swartz’s name was inappropriate (oligantha = few-flowers) for a
plant that has many flowers “(Cr. oligantha Sw. hallucinatione dicta).” Although
Sprengel’s name may have been more descriptive of the plant, nonetheless it is
illegitimate (Ackerman, in press).
Nir (2000) and Govaerts (2008) cited Cranichis tenuiflora Griseb. as synonym
of Prescottia oligantha, but a careful examination of the original material [Protologue:
“Cuba occ. (Wr. 3292) E.” Type: Cuba: Wright 3292 (AMES!, P!)] reveals it is not a
Prescottia at all. It looks like that Nir (2000) made a confusion, as the author also
cited Cranichis tenuiflora Griseb. as a species in Cranichis, and informed that he saw
the type (Cuba: Wright 3292) at AMES.
At the same herbarium sheet of the holotype of Prescottia micrantha there is
another collection, from Serra de Curral del Rey, Minas Gerais, which is not part of
the type collection. When Lindley described Prescottia tenuis (Lindley 1840), he
cited: “Hab. In Peruvia, Mathews 1862 (exam. s. sp. in hb. Hooker)”. Kew bought
Hooker’s herbarium in 1867.This implies that the holotype of Prescottia tenuis is the
specimen stamped “Herbarium Hookerianum 1867” now at K. At K-L there is an
illustration made by Lindley from the type specimen.
Prescottia myosurus was described based on more than one syntype. Besides
the specimen from Dominica cited on the protologue has no number, Garay & Sweet
(1979) cited Dominica, Imray 228 (K) as the type of P. myosurus. This sheet at K has
different collections, one of it is the Imray 228, and it is determined by Ackerman as
the lectotype of P. myosurus.
202
Cogniaux (1895), Hoehne (1945), Brade & Pabst (1952), Pabst & Dungs
(1975) and Sprunger (1996) accept Prescottia pubescens as a good species.
Hoehne (1945) said that if was not the 3-toothed lip apex he would say it was
Prescottia plantaginifolia. However, it has white flowers, with lip inner surface pilose,
what is completely different from P. plantaginifolia. We are suggesting here that it is a
synonym of P. oligantha.
At the Prescottia nivalis original description, Barbosa-Rodrigues (1881)
asserted that this taxon has small and white flowers. Therefore, after analyzing the
diagnose and illustration we saw that it easily fits within our circumscription of P.
oligantha.
We could not find the type of Prescottia viacola var. polyphylla, however there
is a specimen from the same collector and place at RB (L. Damazio n. 1026, Brazil:
Minas Gerais, Ouro Preto, collected in Aug 1903), the type is not there nor at BR.
As explained before, we are choosing here a lectotype to Barbosa Rodrigues’
names, Prescottia microrhiza, P. pubescens, P. nivalis, and P. viacola, since his
herbarium specimens were lost. Schlechter’s original materials were at B, and most
were destroyed during World War II. Therefore, Azevedo & van den Berg (2007a)
choose a lectotype for Prescottia filiformis and P. gracilis, since it was impossible to
locate any isotype.
Christenson (1995) stated that Henri Pittier collected plants for the US in the
Canal Zone of Panama in 1911. His collections were sent to specialists for
identification and description of new taxa. Christenson (1995) also affirmed that
Orchidaceae were described by Rudolf Schlechter at B herbarium, and published in a
series of papers in 1913. Schlechter did not indicate a herbarium of deposition in his
protologues and, for this reason, his holotypes are assumed to have been at B.
Christenson (1995) verify that the Pittier Panama collections at US are holotypes,
annotated by Schlechter and marked “typ. auct.” in his handwriting, that were sent to
B and returned to US. However, a few duplicates were sent to B as a Schlechter
request. It is clear that it was one of it. Prescottia panamensis was published later
(Schlechter 1920), and the material at US do not have any Schlechter annotation like
“typ. auct.”. Actually, Schlechter determined it as P. oligantha. Probably, Schlechter
changed his mind later and described the new species based on the sent duplicate.
For this reason, we are designating here the US material as the lectotype of P.
203
panamensis. There is also a duplicate of it at AMES, with an original line drawing
made under supervision of Schlechter, and a plant specimen inside a small
envelope. It was probably sent to AMES after describing the new species.

HABITAT. Either in Uruguay or Brazil, this species has a marked preference for
moist and very humid places, with its roots underwater. It has been found among
marshy, paludicolous, open vegetation in full-sun very near to the Atlantic coast.
207
CONSERVATION STATUS. Critically endangered (CR – A1a). Prescottia ostenii was
known only from the type locality, and from two additional collections (see above).
Apparently, it has not been collected again in Uruguay and the type locality has been
considerably modified as a consequence of urban development (Eduardo Alonso Paz
and Eduardo Marchesi, pers.com.). Only now, past more than 70 years, it was
recollected (Singer et al. in press, Chapter 2), and for the first time in Brazil, being the
Brazilian population the only remnant population we are aware of.
ETYMOLOGY. In honor to Dr. Cornelius Osten, German botanist and business man
in Uruguay, its first collector.
NOTES. Prescottia ostenii is one of the most distinctive species in the genus.
Besides it is a very rare and poorly known species, it is easily recognized by its short
and robust habit, with only 5-8 cm in height when in flower, and its dense and thick
inflorescence.
Charles Schweinfurth recognized it as a new species of Prescottia back in
1934. He wrote a note in the GH material, but never described it. Prescottia ostenii
was first described by Pabst (1979), from specimens collected at Canelones,
Uruguay. It was recently recorded for the first time to Brazil (Singer et al. in press,
Chapter 2). So far, it was only known from two collections: C. Osten 16918 (HB), and
C. Osten 22939 (GH, MFVA, MVM, S), which were collected at the same place in
Uruguay.
When Pabst (1979) described this species a holotype was not explicitly
designated as such by the author, however he cited a single specimen on it: Osten
22939. Even though, one year later Pabst (1980) published a note saying: “Prescottia
ostenii Pabst, Bradea 3(3): 18. 1979. holotypus HB 1233, omitted at original
description”, which corresponds to another collection: Osten 16918. Following the
Article 37.3 of the International Code of Botanical Nomenclature (McNeill et al. 2006)
the name was validly published in 1979, and Osten 22939 must be kept as the type,
not Osten 16918 (HB 1233). Six specimens of Osten 22939 were found, at AMES,
GH, MVFA, MVM (2 specimens), and S. The material at S, which bears a Pabst’s
determination label, was recently selected by Azevedo & Van den Berg (2007a) as
the lectotype of P. ostenii. The materials at AMES and GH are marked “Osten 22939
b” and were not accepted as isolectotypes.
208
In the molecular-based phylogeny, Prescottia ostenii is placed in the clade that
unites P. densiflora, P. lancifolia and P. oligantha. Being more closely related to P.
lancifolia. Prescottia ostenii can easily be separated from P. lancifolia and P.
oligantha on the basis of the foliar shape: leaves in P. ostenii are sessile, whereas
are petiolate and lanceolate in P. lancifolia, and shortly petiolate in P. oligantha.
Morphologically, this species most closely resembles P. densiflora, since both share
sessile rosulate leaves, but differs conspicuously in plant size.
No evidence of protandry was found in this taxon (Singer et al. in press,
Chapter 2). Protandry was already reported for some Prescottia species with long
columns, such as P. stachyodes (Sw.) Lindl. and P. montana Barb. Rodr., but it is
likely absent in taxa with short columns (Singer & Sazima 2001).

HABITAT. Grows on sandy soils, in campos de altitude (high altitude grasslands) of
Southeastern Brazil, in elevations between 1.400 and 2.000 m.
CONSERVATION STATUS. Not endangered.
NOTES. Prescottia phleoides is characterized by its sessile to pseudopetiolate,
oblong to lanceolate leaves, congest inflorescence, and long floral bracts. This
species has affinities with Prescottia mucugensis and P. leptostachya. It is more
closely related to P. mucugensis and their relationships are discussed under the
description of that species (Azevedo et al. submitted b, Chapter 2).
The holotype of Prescottia phleoides is located at M. It is annotated in
Martius’s handwriting with the same information given in the protologue. There is a
fragment of what appears to be the same material at W, with an illustration probably
made by Martius. There is also an illustration of the type material at K-L made by
Lindley.

HABITAT. Prescottia plantaginifolia occurs in open areas in soil or rocky places at
elevations from sea level to 2.000 m, and also in disturbed habitats such as road
banks.
CONSERVATION STATUS. Not threatened.
ETYMOLOGY. The epithet plantaginea was in reference of the inflorescence aspect,
which looks like an inflorescence of Plantago.
NOTES. Prescottia plantaginifolia is very variable. It is characterized by the oblong to
lanceolate, sessile to pseudopetiolate leaves, with green flowers and lip internally
glabrous. According to phylogenetic studies this species is sister to Prescottia
spiranthophylla. They share some morphological similarities as lip with outer surface
with trichomes at the base, and column with dorsal surface covered by trichomes,
characters exclusive of these two taxa. Prescottia plantaginifolia differs from P.
spiranthophylla by the plant size, the loose inflorescence and the flowers with lateral
sepal revolute, whereas in P. spiranthophylla the inflorescence is congest and the
flowers have the lateral sepals reflexed with the distal part adpressed to ovary or
reflexed.
When Hoehne (1945) described Prescottia plantaginea var. macrostachya he
stated that probably the variety constitutes a transition to Prescottia spiranthophylla,
differing from it by its flowers, which are less dark and less congest than those of P.
spiranthophylla, but more congest than those of P. plantaginifolia. However, all
specimens that we have seen comprise our circumscription of P. plantaginifolia.
Cogniaux (1895), Hoehne (1945), Pabst (1966), and Pabst & Dungs (1975)
considered Prescottia rodeiensis as a good species, although Hoehne (1945) and
Pabst (1966) expressed that it is very similar to P. plantaginifolia, differing only by the
emarginate petal apex. Pabst (1966) commented that it seems to be a rare species,
because he had never seen it. Hoehne (1945) also remarked that no specimen was
recollected after the type, and questioned the possibility of an anomaly at the original
222
material. As we also could not find any other collection like the type, and as it is really
similar to P. plantaginifolia, we are here considering it as a synonym of the latter.

HABITAT. Prescottia spiranthophylla is found growing together with species of
Bromeliaceae and Cactaceae on granitic substrates, at elevations from 100 to 460 m
CONSERVATION STATUS. Not endangered.
ETYMOLOGY. The name is due to the spiralled leaves.
NOTES. The main distinguishing characteristics of Prescottia spiranthophylla is its
robust and vigorous habit, with big sessile leaves and congest inflorescence.
Phylogenetically and also morphologically it is closely related to Prescottia
plantaginifolia. They both share two characters that are, apparently, exclusive of
them in the genus: the lip outer surface with trichomes at the base, and the dorsal
surface of the column covered by trichomes.
227
Cogniaux (1895) transcribed the Barbosa Rodrigues’ original description,
saying that he did not saw the original material. Hoehne (1945), commented that the
original diagnose is not sufficient to recognize the species. Besides the comment, he
decided to make a new diagnose and presented an illustration to establish the
species. Pabst (1966) considered it a synonym of Prescottia plantaginifolia, followed
by Pabst & Dungs (1975) and Sprunger (1996). Here we are reestablishing the
species, based on morphological characters and also on DNA sequence data.
Barbosa Rodrigues made very good illustrations of his collections, which are
mentioned by him in the original description. Those illustrations were recently
reproduced in Sprunger et al. (1996). Many of these have been chosen as the
lectotypes of his names. When Barbosa Rodrigues described Prescottia
spiranthophylla he cited a plate (t. 501), although the original drawing was never
found; probably it was lost. It was not printed in “Iconographie des Orchidées du
Brésil” (Sprunger et al. 1996), nor it is at the library of the Rio de Janeiro Botanical
Garden, where are the other original plates of Barbosa Rodrigues. We have chosen
here one of the two specimens cited by Hoehne (1945), Brade & Lutz 15, as the
neotype of Prescottia spiranthophylla. Besides, it has as site of collection “Distrito
Federal”. It was certainly collected at Rio de Janeiro, which was the Federal District
of Brazil until the foundation of Brasília, around 1960.

HABITAT. Terrestrial in thick leaf litter in shade of broadleaf forests of moist and wet,
lowland to montane regions. Elevation from sea level to 3.600 m.
CONSERVATION STATUS. Not endangered.
ETYMOLOGY. From the Greek stachy (relating to a spike) and odes (resembling) in
reference to the shape of the inflorescence (McLeish et al. 1995).
NOTES. Prescottia stachyodes is a widespread species, very variable in shape and
size. It has lanceolate to elliptic leaves, clearly petiolate, with green flowers and lip
internally glabrous. The leaves are whole green or with the center whitish, with or
without white margin, entire to lightly serrated. The leaves of Prescottia stachyodes
are very variable in its format and dimensions, apparently related to the places where
the plants grow. Plants that grow on rocks differ a lot from those that inhabit the soil.
This variation was probably the reason for the large number of synonyms for this
species.
As currently circumscribed it encloses a large range of variation in size, color,
and shape. The delimitation here proposed to Prescottia stachyodes is a broadened
circumscription, and includes some morphs. We could not find any geographic or
ecologic pattern and significant variations were not found. There is a continuous
morphological variation, even in specimens of the same collection and population.
The seed morphology of this taxon is very characteristic and distinct from all other
species of the genus (with fusiform intercellular spaces with beaded appearance). All
the different morphs studied, coming from different regions, have the same kind of
seed. We suggest that a population study should be carried out to clarify the species
within this complex.
These plants appear to be self-pollinating, since virtually all flowers set fruit.
Singer & Sazima (2001) verified that P. stachyodes is self-compatible but pollinatordependent. However, germinated pollen was observed in the anther cavity, near the
256
clinandrium, as reported for Epipactis microphylla (Ehrh.) Sw. (Bonatti et al. 2006).
The clinandrium, somehow turn back and the pollen come into contact to the
stigmatic surface. This is an efficient way to ensure seed set, independently of the
presence of pollinators. These conditions would explain somewhat distinct variants
growing sympatrically.
As Cranichis oligantha, C. stachyodes was described without type information.
Fawcett & Rendle (1910), Garay & Sweet (1979), Garay (1978) and McLeish et al.
(1995) cited that it is at BM, although, Serna & Ferrari (1998) cited that it is at S and
Nir (2000) cited that it is at S and BM. To avoid more confusion Azevedo & van den
Berg (2007a), selected the BM specimen as the lectotype of C. stachyodes, as this is
the only specimen that can be undoubtedly attributed to Swartz and to the type
location.
Prescottia colorans was described as a Prescottia of one leaf and with
purplish scape, probably the reason of the name. The holotype of Prescottia colorans
is annotated in Lindley’s handwriting with the information “Brasil Loddiges”, in
agreement with the information given in the protologue. This herbarium sheet has
two collections, one being the type, a single inflorescence, without leaves and an
illustration, and the other “Wright 626, in Cuba Orientali”, which is not part of the type.
It was collected in July 1856, in other words, after P. colorans publication (Lindley
1836), but it was also determined and cited by Lindley (1858) as a P. colorans, what
evidences that Lindley’s circumscription of P. colorans included big specimens not
only from Brazil, but also from Cuba.
When Lindley described Prescottia petiolaris (Lindley 1836), he did not say
where the type come from. Latter, Lindley (1840a) cited it as: Hab. in Peruvia,
Mathews, 1875 (exam. s. sp. in hb. Hooker). The specimen at K is stamped
“Herbarium Hookerianum 1867” (1867 being the year that Kew bought Hooker’s
herbarium) it implies that it is the holotype of Prescottia petiolaris. There is also a
herbarium sheet at Lindley’s herbarium that is a line drawing of the type made by
himself at Hooker’s herbarium.
The type of Prescottia pellucida is characterized by specimens with large
flowers (lip 4.5-5.0 mm long) and short petioles (1.5-3.0 cm long). In Flowering Plants
of Jamaica, Adams (1972) recognized Prescottia pellucida as a good species (as
well as Ackerman 1989; 1995) but expressed some doubts and suggested that it may
257
simply be an ecological variant of P. stachyodes. Prescottia pellucida was regarded
as synonym of P. stachyodes based on morphometric data taken from herbarium
specimens collected throughout the Greater Antilles (Ackerman 2000). Nir (2000)
recognized Prescottia pellucida as a good species, and cited: Cuba, Loma del Gato,
Wright 626 (K – L) as its type, but without seen the specimen. However, this number
was cited by Lindley (1858) at the same time he published Prescottia pellucida,
exactly the line before it, as Prescottia colorans. This specimen (Wright 626) is quite
different of P. pellucida’s type.
At the protologue of Prescottia pellucida, where Lindley (1858) presented a list
of orchidaceous plants collected in the east of Cuba by Mr. C. Wright, he explicitly
says: Loma del Gato (no number). Ackerman (1989, 2000) cited: Cuba, Loma del
Gato, Wright s.n. (holotype K-L!, photograph of specimen at UPRRP!) as the type of
the species. The problem is that the material at K-L has three collections in the same
sheet. One was collected in Monte Verde and has a number (1473), and was
collected after the description, in 1859, what excludes it as a possible type material.
The other has no year, and has handwritten: “Prescottia pellucida?”, but it has only
one leaf, instead of two leaves as described at the protologue. The other one (the left
one) has two leaves, no number, and was collected in 1856-7 in “Cuba Orientali”. It
has Lindley’s line drawing under it, and we are here selecting it as the lectotype of P.
pellucida.
When Schlechter described Prescottia smithii he did not cite where the type
was deposited. Four specimens of Smith 2277 were found at CM, GH, K, and NY.
The original material of P. smithii was probably at B, but it could not be found and
was probably destroyed during World War II. The original materials of Smith were
distributed by NY, and for this reason it was selected as the lectotype of P. smithii
(Azevedo & van den Berg 2007a).
When Schlechter (1921) described Prescottia longipetiolata the author
characterized the new species as similar to P. stachyodes, but with smaller flowers in
a dense inflorescence, remarking that the type has only a notably long petiolate leaf,
which was also emphasized by Lindley (1836) as a characteristic of P. colorans. As
Barbosa-Rodrigues had already used the epithet longipetiolata before in 1877,
Hoehne (1945) choose Prescottia schlechteri as a nomen novum to Prescottia
longipetiolata Schltr. Prescottia longipetiolata was considered as synonym of
258
Prescottia cordifolia Rchb. f. by Hoehne (1945), Garay (1978), Hamer (1984),
Govaerts (2004), and here we consider it as a synonym of P. stachyodes.
Schlechter’s original materials were at B, and were mostly destroyed during
World War II. As Azevedo & van den Berg (2007a) could not find any isotype of
Prescottia longifolia they selected a lectotype for it. The same situation happened
with Prescottia longipetiolata, therefore we choose to lectotypify this name under the
line illustration printed in Mansfeld (1929) Figuren Atlas zu den Orchideenfloren der
sudamerikanischen Kordillerenstaaten von R. Schlechter t. 291.
When Carnevali & Vargas (1996) described Prescottia tepuyensis, they said
that this taxon is very closely related to P. stachyodes, but the plants and flowers are
consistently smaller, and the floral bracts are proportionally shorter. However in size
it is very similar to the type of P. stachyodes. Carnevali & Vargas (1996) stated that
small specimens of P. stachyodes have leaves of at least 10 cm long but are usually
longer than 15 cm, and in P. tepuyensis the leaves do not exceed 8 cm long (differing
from the information given at the description: 8 - 11 cm long). The type of P.
stachyodes has leaves 7 - 9 cm long. Prescottia stachyodes is extremely variable in
shape and size and the type of P. tepuyensis easily falls within our circumscription of
P. stachyodes.

Doubtful Names
1. Prescottia auyantepuiensis Carnevali & G.A. Romero, Orchids Venezuela, ed. 2:
1145. 2000. Protologue: “Venezuela: Bolivar, Auyantepui, 2000--2100 m, G.C.K.
Dunsterville 866 (holotype: AMES drawing)”.
Prescottia auyantepuiensis was described as similar to Prescottia tubulosa
differing of it by its linear leaves(Carnevali & Romero, 2000). Its etymology is in
reference to the type locality, Auyantepui, a table-top mountain in southern
Venezuela (Carnevali & Romero, 2000). However as the holotype of Prescottia
auyantepuiensis is a drawing, we are here considering it as a doubtful name, once
we could not confirm the real circumscription of the species.
2. Prescottia corcovadensis Rchb. f., Linnaea 22: 814. 1849. Protologue: “Zwischen
Gestrauch der inneren Berge des Corcovado Brasiliens. Octob. 1822. Beyrich.”
Type: Brazil: Rio de Janeiro, Corcovado, Beyrich s.n. (not in W).
Cogniaux (1895) and Schlechter (1926) recognized it as a good species. Brade
& Pabst (1952) cited it as synonym of Prescottia plantaginifolia. Wiggins & Porter
(1971) cited it as synonym of Prescottia oligantha. Since we could not locate any
type material, we are here placing this taxon as a doubtful name.
3. Prescottia cordifolia Rchb. f., Bonplandia 3: 66. 1855. Protologue: “Aspasica.”
without collector and date. Type: Colombia: Norte de Santander, Aspasica,
Wagener s.n. (not in W).
Prescottia cordifolia was described from a material from Colombia, but its type
was not found. The protologue says mainly that the species is similar to Prescottia
colorans, and present leaf 15 cm long, with cordate base.
Garay (1978), Hamer (1984), Jørgensen & León-Yánez (1999) and Stevens et
al. (2001) recognized it as a good species. Dod (1986) also recognized Prescottia
cordifolia as a good species, but stated that its flower shows few differences from
262
those of P. stachyodes. Hamer (1984) observed that Prescottia cordifolia is a much
larger plant with larger flowers than P. stachyodes, according to the author, a close
ally, that may be distinguished by the larger, cordate leaf, generally only one leaf and
by the green and not purplish flowers. We believe that it may be larger than the P.
stachyodes type, but is very similar to P. colorans type which has also only one large
leaf. Ackerman (in press.) stated that P. cordifolia may not be distinguished from P.
stachyodes. We recognize that it must be related to our circumscription of P.
stachyodes, but because we could not found the type, and there is no illustration, we
are here considering it as a doubtful name, once it is not possible to confirm this
information and the real circumscription of the species.
4. Prescottia polyphylla Porsch., Oesterr. Bot. Z. 55: 153. 1905. Protologue: “in
Waldern bei Barra Mansa im Gebiet der Stadt Itapecirica 100 m.s.m. VI.1901
(leg. Wettstein et Schiffner)” without collector number.
The type material of Prescottia polyphylla Porsch was not found, and there is no
type illustation. Additionaly, the original description is not very informative, a couple
of species could fit in its description. The protologue does not have a good
description or any measurement. The only known figure of P. polyphylla is a line
drawing of a flower (front and side view) in Wettstein (1908), together with a
description of the species, which did not clarify its circumscription. This species was
accepted by Hoehne (1945), who considereded it near to Prescottia lancifolia, P.
microrhiza, P. epiphyta and P. octopollinica. Hoehne (1945) commented that he was
reluctant to distinguish Prescottia polyphylla from P. lancifolia, justifying that it would
be the transition of the latter and P. microrhiza. However, those four species present
the inner surface of the lip pilose, and one of the few informative character on
Porsch’s (1905) description was that the lip was glabrous on both sides (utrimque
glaberrimo). Nevertheless, Hoehne (1945) considered that P. polyphylla has the
inner surface of the lip base pilose and the rest glabrous. As we can not really
confirm how P. polyphylla looks like, it is hard to recognize the real circumscription of
this species.
263
5. Prescottia polysphaera Schltr., Repert. Spec. Nov. Regni Veg. 16: 357. 1920.
Protologue: “Brasilien: Rio Grande do Sul - H. Wendt anno 1907.” without
collector number.
Schlechter’s original materials were at B, most of them were destroyed during
World War II. For some names it was impossible to locate syntypes, isotypes, or
drawings. Prescottia polysphaera was first cited as synonym of Prescottia densiflora
by Hoehne (1945) and Brade & Pabst (1952) and subsequently cited as synonym of
Prescottia oligantha by Dunsterville & Garay (1966), Wiggins & Porter (1971),
Sprunger (1991), Sprunger (1996), Govaerts (2004) and Rocha & Waechter (2006).
However, Schlechter said that its habit reminds the kind of P. epiphyta. From its
description we could see that it is a plant with intermediate size (12 – 22 cm high),
with petiolate leaves (petiole 1.5 – 4 cm long), and blade 4 – 9 cm long. As we could
not find any type material it is hard to confirm what is the real circunscription of this
taxon.
Nomen nudum
1. Prescottia gigantea Lodd. ex W. Baxter, J.C. Loudon, Suppl. Hort. Brit.: 618, 185.
1850. nom. nud.
Besides Cogniaux (1895) have cited it as synonym of Prescottia stachyodes, it
is impossible to know anything about this name, no specimen, collector, collector
number, nor location were cited. It is only a name on a catalogue, without description
or diagnosis.
2. Prescottia lanceaefolia Link & Otto ex Steud., Nom. ed. 2. 2: 393. 1841. nom.
nud.
Hoehne (1945) have cited this species as synonym of Prescottia lancifolia, but
it was also published without a description or diagnosis.
264
3. Prescottia serrana M.N. Correa, Parodiana 7 (1-2): 6, fig. 2. 1992. Protologue:
“Exsiccatum. Jujuy. Depto. Capital, mina 9 de Octubre, sierra de Zapla, subida al co.
Zapla, 13-4-1974, A.L. Cabrera et R. Kiesling 24954 (LP)”. nom. nud.
When Correa (1992) described Prescottia serrana he provided a Latin and a
Spanish description, an illustration, and cited the material: A.L. Cabrera et R. Kiesling
24954 (LP). The author did not mention the words "typus" or "holotypus", or its
equivalent in a modern language, what makes the publication invalid following the
Article 37.6. of the International Code of Botanical Nomenclature (McNeill et al.
2006). Furthermore, a careful examination of the original publication (Correa 1992)
reveals that Correa (1992) was not sure about the new species. Correa (1992) said:
“Prescottia serrana, a juzgar por la descripción y la ilustración de Hoehne (1945),
sería afín a P. montana, especie de Minas Gerais (Brasil) pero hasta el momento no
he logrado ver suficiente material”. After seeing the “type” of P. serrana we confirmed
that it is really a specimen of P. montana.

Molecular studies place Pseudocranichis thysanochila as sister to Prescottia
tubulosa, making Prescottia paraphyletic (Figueroa et al. 2008, Álvarez-Molina &
Cameron 2009, Salazar et al. 2009). To accomplish monophyly to Prescottia, Salazar
(2009) transferred Prescottia tubulosa and Pseudocranichis thysanochila to
Galeoglossum A. Rich. & Galeotti.

CONCLUSÕES GERAIS

Conclusões Gerais
Neste trabalho foi apresentada a primeira compilação de informações para o
gênero Prescottia como um todo. Quinze espécies de Prescottia são aceitas, dentre
as quais duas são novas: Prescottia mucugensis e P. ecuadorensis. Além disso,
duas propostas de conservação de nomes foram submetidas. A ocorrência de
Prescottia ostenii foi registrada para o Brasil e a de Prescottia glazioviana para
Minas Gerais. Foram propostas 23 lectotipificações, uma neotipificação e 11 novas
sinonimizações. Prescottia spiranthophylla foi restabelecida como espécie e quatro
nomina nuda foram detectados.
Existem poucos caracteres qualitativos macro-morfológicos que podem ser
utilizados para delimitar as espécies de Prescottia. Dentre os caracteres utilizados, o
desenvolvimento dos pecíolos, a coloração das flores, a posição das sépalas e
pétalas e a presença de tricomas no interior do labelo foram os mais úteis. Do ponto
de vista micro-morfológico, os caracteres também são pouco informativos e muito
variáveis, destacando-se a morfologia da superfície das sementes analisadas em
microscópio eletrônico de varredura.
A análise de grande número de espécimes em herbário, juntamente com o
trabalho de campo, permitiu observações detalhadas das populações, tanto do ponto
de vista morfológico quanto ecológico. Além disso, a manutenção de plantas em
cultivo possibilitou o conhecimento mais aprofundado da variação dos caracteres
morfológicos nos táxons.
Grande parte das espécies de Prescottia é pouco coletada. Em parte devido à
dificuldade de encontrar as plantas em campo, uma vez que, além de pequenas,
após o ciclo reprodutivo, elas perdem toda a porção vegetativa, e em parte pela
raridade de algumas espécies. Prescottia oliganta (25%), P. plantaginifolia (14%) e
P. stachyodes (44%) somam, juntas, 83% do material coletado.
O estudo filogenético aqui apresentado demonstrou o monofiletismo do
gênero e a sua relação de grupo-irmão com Galeoglossum. O gênero aparece
dividido em dois grupos maiores, um agrupando as espécies longo-pecioladas e o
outro o restante das espécies amostradas, representado por espécies com pecíolos
curtos, pseudopecioladas e sésseis. As espécies que apresentam flores
280
esbranquiçadas e tricomas no interior do labelo formam um grupo monofilético, mas
as espécies de flores esverdeadas e labelo glabro formam um grupo parafilético.
Foi diagnosticada a presença de complexos específicos envolvendo
Prescottia oligantha e P. stachyodes, que apresentam grande variação morfológica.
A grande variabilidade morfológica observada entre populações de uma mesma
espécie gera dificuldade na delimitação e, consequentemente, identificação das
espécies. Embora não exista dúvida em relação ao monofiletismo do gênero como
aqui aceito, trabalhos adicionais são necessários para confirmar a existência desses
complexos. Deste modo, análises com uma abordagem populacional, inserindo
amostras que englobem populações de várias regiões, incluido seus extremos de
distribuição geográfica, seriam adequadas para confirmar e esclarecer as relações
entre os morfotipos existentes.
A filogenia baseada em dados moleculares foi útil para esclarecer a
circunscrição do gênero e a relação entre suas espécies. Este resultado foi usado
também na discussão das espécies no capítulo 3 e auxiliou no esclarecimento de
questões nomenclaturais no gênero e na descrição da espécie nova apresentada no
capítulo 2.

LEGAL REQUIREMENTS
• Submission of a manuscript implies: that the work described has not been published before
(except in the form of an abstract or as part of a published lecture, or thesis); that it is not under
consideration for publication elsewhere; that its publication has been approved by all co-authors, if
any, as well as by the responsible authorities — tacitly or explicitly — at the institute where the
work has been carried out. The publisher will not be held legally responsible should there be any
claims for compensation.
• The "Copyright Transfer Statement" has to be signed and faxed to the publisher together with the
corrected proofs (see below), which will be provided by the publisher shortly after the manuscript
has been accepted for publication.
MANUSCRIPT PREPARATION
• All manuscripts are subject to peer review and copy editing.
• To speed up the processing of your manuscript, please follow this checklist precisely.
Failure to do so will result in a delay to publication. Please refer to a recent part of KB for
examples of the typographic and layout characteristics of KB.
288
• Manuscripts are written in English and are typed to fit A4 (208 x 298 mm) paper. Text is
double-spaced and in a single column, aligned left with margins of at least 25 mm on each
side. All pages are numbered.
GENERAL
Fonts and typography
• Footers are in 10 pt Times New Roman.
• All other text is in 12 pt Times New Roman.
• Italics are used for the following:
o
plant names at genus level and below (e.g. Cyperus; sect. Rotundi; Cyperus
rotundus);
o
authority names after the Accepted Name when in bold (e.g. L., Boeck., Schott,
Salunkhe & Potdar);
o
collector names in specimen citations (e.g. Kerr 12345);

• Do not italicise any other words, phrases or abbreviations.
• Numbers one to nine are written unless a measurement or in taxonomic descriptions (e.g. four
samples, 2 cm, 35 sites, 6 km). Use 0.12 instead of .12; 1 instead of 1.0; % instead of percent.
• Months are formatted as follows: Jan., Feb., March, April, May, June, July, Aug., Sept., Oct., Nov.,
Dec. Give the year in full, for example 1991 not /91.
• Distinguish between hyphens, typed without spaces (e.g. brown-tomentose; 3-flowered), and enrules, typed with spaces (e.g. leaves 24 – 30 x 10 – 15 cm; inflorescences 2 – 3-flowered).
• Essential footnotes to the text should be numbered consecutively and placed at the bottom of the
page to which they refer.
Units and symbols
• Temperatures should be expressed in degrees Celsius, time in seconds (s), minutes (min), hours
(h), days, etc. Otherwise, the International System of Units (Sl, Systéme International d’Unités)
should be used wherever possible. (Consult, e.g. National Institute of Standards and Technology,
Special Publication 330, International System of Units (SI), latest edition;
http://physics.nist.gov/cuu/Units; or "How many? A Dictionary of Units of Measurements" © Russ
Rowlett and the University of North Carolina at Chapel Hill; http://www.unc.edu/~rowlett/units)
Abbreviations
• For correct usage of abbreviations authors should consult the list of Planta units, symbols and
abbreviations. (Planta units, symbols, abbreviations;
http://www.springerlink.com/content/uuv8vawgvm11j01m/fulltext.pdf)
• Herbarium codes follow Index Herbariorum
(http://sciweb.nybg.org/science2/IndexHerbariorum.asp).
• No full stops after common contractions (e.g. Mt, Mts), nor after points of the compass (N, S, NE
etc.), nor after abbreviations for units of measurement (e.g. mm, cm, km). Include after other
abbreviations (e.g. R., fl., fr.).
289
• Use sect., subsp., var. and f. for section, subspecies, variety and form respectively, except at the
start of sentences where the full word is written.
• Use s.l. and s.s. for sensu lato and sensu stricto respectively.
Plant names
• Authors of plant names are cited on first mention of the name in the body of the manuscript at
genus level and below.
• Citations of plant name authors follow Brummitt, R. K. & Powell, E. (eds.) (1992). Authors of Plant
Names. Royal Botanic Gardens, Kew (www.ipni.org).
• The first mention of a genus name in a sentence should be spelt out in full; subsequently, genus
names should be abbreviated to their initial letter, unless this would cause confusion.
Spelling
• Use the ending ‘ise’ in words such as recognise or analyse. Check for consistency of use
throughout the manuscript.
FORMAT & LAYOUT
Title
• The wording should be concise but informative and where appropriate should include the family or
higher taxon and a geographical area.
• If only one taxon forms the subject of the manuscript (e.g. a single new species) the name of the
taxon is included in the title.
• Taxonomic ranks indicated in the title are separated by colons (e.g. Leguminosae: Papilionoideae:
Millettieae).
• Plant name authors are omitted from the title.
Authors
• Author names are placed below the title, in bold.
• Address(es)/affiliation(s) of the author(s) and the e-mail address, telephone and fax numbers of
the corresponding author are placed in a footer on page 1.
• Authors' names and addresses are linked by a superscript number, e.g. J. M. Lock1.
Summary
• The heading ‘Summary’ is in bold on the same line as the text.
• The Summary indicates what the research set out to achieve, how it was carried out and the
degree to which the objectives were reached. It includes any authors of plant names omitted from
the title, the names of all new taxa described and new combinations unless the number is very
large. The methods and main conclusions are also summarised.
• References are not cited in the Summary.
Key words
• The heading ‘Key Words’ is in bold on the same line as the text.
290
• Up to seven key words are provided, in alphabetical order.
• Words already used in the title are not included.
Headings
• Main headings (Introduction, Materials and methods, etc.) are placed on separate lines..
• Headings are in bold, subheadings are not.
• The hierarchy is sensible and consistent.
Keys
• Keys are either bracketed (preferable) or indented, but couplets should always be numbered.
• Taxon names are in bold.
• Plant name authors are not cited in keys.
• A recent issue of KB should be consulted to follow the key layouts used.
Accounts of taxa
Synonyms
• Homotypic synonyms are grouped in chronological order after the accepted name, followed by
heterotypic synonyms, also with their respective homotypic synonyms in chronological order.
• New synonyms are indicated in bold as synon. nov. at the end of the citation for the synonym.
• Illegitimate and invalid names are indicated in bold as nom. illegit. and nom. invalid. respectively
at the end of the citation for the name.
Types
• The herbarium in which the holotype is deposited is cited, as required by the International Code of
Botanical Nomenclature (ICBN).
• Herbaria that are definitely known to hold isotypes are listed.
• If applicable, when lectotypes, neotypes or epitypes are being designated for the first time,
'selected here' is indicated: e.g. Papua, Boridi, Carr 12345 (lectotype K!, selected here;
isolectotypes BRI, L!).
• When lectotypes, neotypes or epitypes have been selected elsewhere, a reference is given:
'Sarawak, Kuching, Smith 34567 (lectotype K!, selected by Bloggs (1977); isolectotypes BRI, L!).'
• When a lectotype has been selected any remaining syntypes are re-designated as lectoparatypes.
They are cited in the list of specimens examined and indicated as such.
• If applicable, the reasons why lectotypes, neotypes and epitypes have been selected and the
reasons for selecting a particular specimen are explained.
• If applicable, type specimens have been seen and are cited for new combinations.
Citation of specimens
• For new taxa, all the material seen is cited.
• Only those label data that add significantly to localising the collection or to field knowledge are
cited.
291
• Label data are normally translated into English, but data for types can be left in the original
language.
• It may be unwise to give precise localities for rare and horticulturally interesting taxa. This factor
should be considered when citing label data.
• If appropriate the number of collections examined is stated, and at least one specimen from each
country in the range of the taxon is cited. In cases of long-standing confusion, there may be a case
for citing all specimens, but reduce detail to a minimum.
• Either use an exclamation mark (!) to show that a specimen has been seen or state in the
introduction that, "All cited specimens have been seen by the author".
• Spellings of place names follow the Times Atlas (12th edition [2007] if possible) and/or Hollis, S. &
Brummitt, R. K. (1992). World Geographical Scheme for Recording Plant Distributions. Hunt
Institute for Botanical Documentation, Pittsburgh.
• Normally accepted English usage place names are cited e.g. Ghana (not Gold Coast), Zimbabwe
(not Rhodesia), Thailand (not Muang Thai), Brazil (not Brasil), Congo (Brazzaville), Congo
(Kinshasa), Burma (not Myanmar), Madagascar (not Malagasy Republic), Sicily (not Sicilia), New
Guinea (for the whole island - the eastern part is Papua New Guinea and the western part, West
Papua).
• Old names of localities, as used on old labels, may be given with the modern equivalent in square
brackets e.g. Stanleyville [Kisangani]; Salisbury [Harare].
• Distances should be cited in metres or kilometres not feet, yards or miles. The original non-metric
label data may be given in square brackets.
• Altitudes are cited in metres to the nearest 50 m. Altitudes in feet on labels are converted to the
nearest 50 m. The original label altitude may be given in square brackets.
• Latitude and longitude (in this order) are cited for obscure localities.
Accounts of new taxa
• New taxa accounts are laid out strictly in the format shown below. Note the positions of indents
and use of spaces, Arial/Times fonts, bold and italics.
• Latin diagnoses compare the new taxon with one or more related taxa, with or without brief Latin
descriptions.
• In large genera, the diagnosis mentions the infrageneric group to which the new taxon belongs, if
such groupings exist. No more than three authority names should be should be cited after the plant
name.
• The full description is in English.
• Types of new species are cited in abbreviated form after the diagnoses and repeated in full
amongst the cited specimens.
• Conservation ratings must be given using the criteria set out in IUCN (2001). IUCN Red List
Categories and Criteria: Version 3.1. IUCN Species Survival Commission. IUCN, Gland,
Switzerland and Cambridge, UK (http://www.iucnredlist.org/static/categories_criteria_3_1). If a
rating cannot be applied then Data Deficient (DD) should be indicated.
Taxa in revisions
• Taxon accounts in revisions are laid out strictly in the format shown below. Note the positions of
indents and use of spaces, Arial/Times fonts, bold and italics.
292
• Name, authority, year and place of publication are cited as, e.g. ‘Mapania meditensis D.A.
Simpson (1992: 42)’ for an accepted name or ‘Hypolytrum soyauxii Boeck. (1882: 25)’ for a
synonym. The full publication is then cited once in the ‘References’ section.
• Conservation ratings must given wherever possible. If a rating cannot be applied then Data
Deficient (DD) should be cited.
• When making new combinations or new names, the name, authority, abbreviated literature
reference, page number and date are cited for the basionym or replaced synonym as, e.g.
Mapaniopsis micrococca T. Koyama, Jap. J. Bot. 20: 130 (1969). The full publication is cited in the
'References' section.
Data
• All DNA sequences are deposited in one of the international nucleotide sequence databases,
either EMBL (www.ebi.ac.uk/embl/) or GenBank (www.ncbi.nlm.nih.gov/).
• For phylogenetic analyses, character state distributions, consistency index, retention index (where
appropriate) and a recognised measure of support for clades (e.g. bootstrap values, decay indices
["Bremer support"], jackknife, etc.) are provided.
• Voucher specimens documenting sources of morphological and molecular data are listed.
Literature citation and references
• Book and journal titles are italicised in the reference list.
• Part numbers of journals are not cited in references.
• Literature citations in the text should be by author and year. If there are more than two authors,
only the first should be named, followed by ‘‘et al.’’ All authors are cited in the 'References' section.
Examples: Manning (1994) showed that... Field studies in Cameroon (Smith & Jones 1994) have
shown that ... Muasya & Simpson (2002) have shown that … Liu et al. (1994) have shown that ...
• The following are used within reason: loc. cit. [same work, same volume, same page]; tom. cit.
[same work, same volume, different page - give page number]; op. cit. [same work; different
volume; different page — give volume and page numbers].
• Abbreviated literature references cited in the text have the following formats depending on the
context: Bloggs (1962), Bloggs (1962: 234), (Bloggs 1962), (Bloggs 1962: 234), (Bloggs 1962;
Another 1976).
• References at the end of the paper should be listed in alphabetical order by the first author's
name. If there is more than one work by the same author or team of authors in the same year, a, b,
etc. is added to the year both in the text and in the list of references.
• For indents use tab stops or other commands, not the space bar.
• Book abbreviations follow Stafleu, F.A. & Cowan, R.S. (1976 – 1988). Taxonomic Literature. (2nd
ed.) Bohn, Scheltema & Holkema, Utrecht. Later Supplements are also available. Note that KB
capitalises most words. If in doubt, do not abbreviate.
• Journal abbreviations follow Bridson, G. D. R., Townsend, S. A., Polen, E. A. & Smith, E. R.
(2004). BPH-2. Periodicals with botanical content. Constituting a second edition of BotanicoPeriodicum-Huntianum. Vols 1 & 2. Hunt Institute for Botanical Documentation, Carnegie Mellon
University, Pittsburgh. The principles therein should allow the correct abbreviations to be made for
journals not included. If in doubt, do not abbreviate.
• Kew Bulletin up to and including 1941 is cited as (for example): Bull. Misc. Inform., Kew 1929: 16 –
28. From Vol.1 (1946) it is cited as (for example): Kew Bull. 44: 601 – 680. Note that this is not as
in BPH.
293
• A useful website for searching both book and journal abbreviations is
http://asaweb.huh.harvard.edu:8080/databases/publication_index.html.
• Page numbers are separated by an en-rule plus spaces (i.e., 1 – 2 not 1-2).
• Part numbers of volumes are not included unless the parts are separately paginated.
• Plant names at genus level and below are italicised in references, whether or not they were in
italics in the original reference.
• The total numbers of pages in single works are not included.

Acknowledgements
• These are kept brief. Do not give the full title of any institute that has an accepted Index
Herbariorum Code.
TABLES & FIGURES
Tables
• Tables are numbered consecutively with arabic numerals and submitted separately from the text.
They have a title and a footnote explaining any abbreviation used in that table. Footnotes to tables
should be indicated by superscript lower-case letters. Double documentation of the same points in
figures and tables is not acceptable.
Figures
• All figures (photographs, illustrations or graphs) should be cited in the text, and numbered
consecutively throughout (Fig. 1, etc); maps are numbered separately (Map 1, etc.) and must be
referred to in the text. Figure parts should be identified by upper-case roman letters (A, B, etc.), "I"
or "O" are not used. Scale bars are included on illustrations and the scale bar measurement is
written in the legend (e.g. scale bar = 1 mm).
• Figure legends must be brief, self-sufficient explanations of the illustrations. The legends should be
placed at the end of the text.
• Full- or part-page figures are acceptable. The figures, including legends, should match either the
column width (78 mm) or the print area of 230 x 165 mm. The publisher reserves the right to
reduce or enlarge illustrations, hence scale bars are used and not magnification factors.
• Submit all figures as separate files and do not integrate them within the text. The preferred figure
formats are EPS for vector graphics exported from a drawing program and TIFF for halftones and
line drawings. EPS files must always contain a preview in TIFF of the figure. The file name should
include the figure number.
294
• All taxa newly described in the manuscript should be accompanied by a good quality line drawing.
All lines and symbols should be of uniform thickness, and of professional quality and proper
dimensions (approx. 2 mm high after reproduction). All line drawings are scanned and submitted
as 1200 dpi TIFF files.
• Photographs ('Plates') for continuous tone reproduction are of the highest quality. They show good
tonal range and are absolutely sharp. They are provided as TIFF files at 300 dpi, either at the final
size or slightly larger.
• Colour figures will always be published in colour in the online version. Illustrations are printed in
black and white unless colour is scientifically necessary. Authors have the option to pay for
additional colour printing. Save colour illustrations as RGB (8 bits per channel) in TIFF format.
ELECTRONIC SUPPLEMENTARY MATERIAL
• Electronic Supplementary Material (ESM) for a paper is published in the electronic edition of this
journal provided the material is submitted in electronic form together with the manuscript.
Reference will be given in the printed version.
•
ESM may consist of information that cannot be printed: animations, video clips, sound recordings
(use QuickTime, .avi, .mpeg, animated GIFs, or any other common file format) information that is
more convenient in electronic form: sequences, check lists, etc.; or large quantities of original data
that relate to the paper, e.g. additional tables, large numbers of illustrations (colour and black &
white) etc.
•
Legends must be brief, self-sufficient explanations of the ESM. The file size should not exceed 2
MB. ESM is to be numbered and referred to as S1, S2, etc.

pela primeira vez, vá para a página de ‘Cadastro’ e registrese, criando um ‘login’ e ‘senha’. Se você está realmente
registrado, mas esqueceu seus dados e não tem como
acessar o sistema, clique em ‘Esqueceu sua senha’.
O processo de submissão on-line é fácil e autoexplicativo. São apenas 5 (cinco) passos. Tutorial do
processo de submissão pode ser obtido em http://www.
botanica.org.br/ojs/public/tutorialautores.pdf. Se você
tiver problemas de acesso ao sistema, cadastro ou envio
de manuscrito (documentos principal e suplementares), por
favor, entre em contato com o nosso Suporte Técnico.
Custos de publicação. O artigo terá publicacão gratuita,
se pelo menos um dos autores do manuscrito for associado
da SBB, quite com o exercício correspondente ao ano de
publicação, e desde que o número de páginas impressas
(editadas em programa de editoração eletrônica) não
ultrapasse o limite máximo de 14 páginas (incluindo figuras
e tabelas). Para cada página excedente assim impressa, será
cobrado o valor de R$ 35,00. A critério do Corpo Editorial,
mediante entendimentos prévios, artigos mais extensos que
o limite poderão ser aceitos, sendo o excedente de páginas
impressas custeado pelo(s) autor(es). Aos autores nãoassociados ou associados em atraso com as anuidades, serão
cobrados os custos da publicação por página impressa (R$
35,00 por página), a serem pagos quando da solicitação
de leitura de prova editorada, para correção dos autores.
No caso de submissão de figuras coloridas, as despesas
de impressão a cores serão repassadas aos autores
(associados ou não-associados). Consulte o Editor-Chefe
para maiores detalhes.
Seguindo a política do Open Access do Public Knowledge
Project, assim que publicados, os autores receberão a URL
que dará acesso ao arquivo em formato Adobe® PDF
(Portable Document Format). Os autores não mais receberão
cópias impressas do seu manuscrito publicado.
Publicação e processo de avaliação. Durante o processo de
submissão, os autores deverão enviar uma carta de submissão
(como um documento suplementar), explicando o motivo
de publicar na Revista, a importância do seu trabalho para
o contexto de sua área e a relevância científica do mesmo.
Os manuscritos submetidos serão enviados para assessores,
a menos que não se enquadrem no escopo da Revista. Os
manuscritos serão sempre avaliados por dois especialistas
que terão a tarefa de fornecer um parecer, tão logo quanto
possível. Um terceiro assessor será consultado caso seja
necessário. Os assessores não serão obrigados a assinar os
seus relatórios de avaliação, mas serão convidados a fazê-lo.
O autor responsável pela submissão poderá acompanhar o
progresso de avaliação do seu manuscrito, a qualquer tempo,
desde que esteja logado no sistema da Revista.
Preparando os arquivos. Os textos do manuscrito deverão
ser formatados usando a fonte Times New Roman, tamanho
12, com espaçamento entre linhas 1,5 e numeração
contínua de linhas, desde a primeira página. Todas as
margens deverão ser ajustadas para 1,5 cm, com tamanho de
página de papel A4. Todas as páginas deverão ser numeradas
seqüencialmente.
O manuscrito deverá estar em formato Microsoft® Word
DOC. O documento deverá ser compatível com a versão
2002. Arquivos em formato RTF também serão aceitos.
Arquivos em formato Adobe® PDF não serão aceitos. O
documento principal não deverá incluir qualquer tipo
de figura ou tabela. Estas deverão ser submetidas como
documentos suplementares, separadamente.
O manuscrito submetido (documento principal,
acrescido de documentos suplementares, como figuras e
2
299

Diretrizes para autores
figura, deverão ser fornecidas as seguintes informações,
em ordem numérica crescente: número da figura, usando
algarismos arábicos (Figura 1, por exemplo; não abrevie);
legenda detalhada, com até 300 caracteres (incluindo
espaços). Legendas das figuras necessitam conter nomes
dos táxons com respectivos autores, informações da área
de estudo ou do grupo taxonômico.
Itens da tabela, que estejam abreviados, deverão ser
escritos por extenso na legenda. Todos os nomes dos gêneros
precisam estar por extenso nas legendas das tabelas.
Normas gerais para todo o texto. Palavras em latim no
título ou no texto, como por exemplo: in vivo, in vitro, in
loco, et al. deverão estar grafadas em itálico. Os nomes
científicos, incluindo os gêneros e categorias infragenéricas,
deverão estar em itálico. Citar nomes das espécies por
extenso, na primeira menção do parágrafo, acompanhados
de autor, na primeira menção no texto. Se houver uma
tabela geral das espécies citadas, o nome dos autores deverá
aparecer somente na tabela. Evitar notas de rodapé.
As siglas e abreviaturas, quando utilizadas pela
primeira vez, deverão ser precedidas do seu significado
por extenso. Ex.: Universidade Federal de Pernambuco
(UFPE); Microscopia Eletrônica de Varredura (MEV).
Usar abreviaturas das unidades de medida de acordo com o
Sistema Internacional de Medidas (por exemplo 11 cm, 2,4
μm). O número deverá ser separado da unidade, com exceção
de percentagem, graus, minutos e segundos de coordenadas
geográficas (90%, 17°46’17” S, por exemplo).
Para unidades compostas, usar o símbolo de cada unidade
individualmente, separado por um espaço apenas. Ex.: mg
kg-1, μmol m-2 s-1, mg L-1. Litro e suas subunidades
deverão ser grafados em maiúsculo. Ex.: L , mL, μL.
Quando vários números forem citados em seqüência, grafar
a unidade da medida apenas no último (Ex.: 20, 25, 30 e 35
°C). Escrever por extenso os números de zero a nove (não
os maiores), a menos que sejam acompanhados de unidade
de medida. Exemplo: quatro árvores; 10 árvores; 6,0 mm;
1,0-4,0 mm; 125 exsicatas.
Para normatização do uso de notações matemáticas,
obtenha o arquivo contendo as instruções específicas em
http://www.botanica.org.br/ojs/public/matematica.pdf.
O Equation, um acessório do Word, está programado
para obedecer as demais convenções matemáticas, como
espaçamentos entre sinais e elementos das expressões,
alinhamento das frações e outros. Assim, o uso desse
acessório é recomendado.
Em trabalhos taxonômicos, o material botânico
examinado deverá ser selecionado de maneira a citarem-se
apenas aqueles representativos do táxon em questão, na
seguinte ordem e obedecendo o tipo de fonte das letras:
PAÍS. Estado: Município, data, fenologia, coletor(es)
número do(s) coletor(es) (sigla do Herbário).
Exemplo:
BRASIL. São Paulo: Santo André, 3/XI/1997, fl. fr.,
Milanez 435 (SP).
No caso de mais de três coletores, citar o primeiro seguido
de et al. Ex.: Silva et al.
Chaves de identificação deverão ser, preferencialmente,
300
3
indentadas. Nomes de autores de táxons não deverão
aparecer. Os táxons da chave, se tratados no texto, deverão
ser numerados seguindo a ordem alfabética.
Exemplo:
1. Plantas terrestres
2. Folhas orbiculares, mais de 10 cm diâm. .....................
............................................................. 2. S. orbicularis
2. Folhas sagitadas, menos de 8 cm compr. .....................
................................................................ 4. S. sagittalis
1. Plantas aquáticas
3. Flores brancas ..................................... 1. S. albicans
3. Flores vermelhas ............................... 3. S. purpurea
O tratamento taxonômico no texto deverá reservar
o itálico e o negrito simultâneos apenas para os nomes
de táxons válidos. Basiônimo e sinonímia aparecerão
apenas em itálico. Autores de nomes científicos deverão
ser citados de forma abreviada, de acordo com o índice
taxonômico do grupo em pauta (Brummit & Powell 1992
para Fanerógamas).
Exemplo:
1. Sepulveda albicans L., Sp. pl. 2: 25. 1753.
Pertencia albicans Sw., Fl. bras. 4: 37, t. 23, f. 5. 1870.
Fig. 1-12
Subdivisões dentro de Material e métodos ou de
Resultados e/ou Discussão deverão ser grafadas com a
primeira letra em maísculo, seguida de um traço (-) e do
texto na mesma linha.
Exemplo: Área de estudo - localiza-se ...
2. DOCUMENTOS SUPLEMENTARES
2.1. Carta de submissão. Deverá ser enviada como um
arquivo separado. Use a carta de submissão para explicitar o
motivo da escolha da Acta Botanica Brasilica, a importância
do seu trabalho para o contexto de sua área e a relevância
científica do mesmo.
2.2. Figuras. Todas as figuras apresentadas deverão,
obrigatoriamente, ter chamada no texto. Todas as imagens
(ilustrações, fotografias, eletromicrografias e gráficos) são
consideradas como ‘figuras’. Figuras coloridas poderão
ser aceitas, a critério do Corpo Editorial, que deverá
ser previamente consultado. O(s) autor(es) deverão se
responsabilizar pelos custos de impressão.
Não envie figuras com legendas na base das mesmas. As
legendas deverão ser enviadas no final do documento
principal.
As figuras deverão ser referidas no texto com a primeira
letra em maiúsculo, de forma abreviada e sem plural (Fig.1,
por exemplo).
As figuras deverão ser numeradas seqüencialmente, com
algarismos arábicos, colocados no canto inferior direito. Na
editoração final, a largura máxima das figuras será de: 175
mm, para duas colunas, e de 82 mm, para uma coluna.
Cada figura deverá ser editada para minimizar as áreas
com espaços em branco, optimizando o tamanho final da
ilustração.
Escalas das figuras deverão ser fornecidas com os valores
4
301
Acta Botanica Brasilica
apropriados e deverão fazer parte da própria figura (inseridas
com o uso de um editor de imagens, como o Adobe®
Photoshop, por exemplo), sendo posicionadas no canto
inferior esquerdo, sempre que possível.
Ilustrações em preto e branco deverão ser fornecidas com
aproximadamente 300 dpi de resolução, em formato TIF.
Ilustrações mais detalhadas, como ilustrações botânicas
ou zoológicas, deverão ser fornecidas com resoluções de,
pelo menos, 600 dpi, em formato TIF. Para fotografias (em
preto e branco ou coloridas) e eletromicrografias, forneça
imagens em formato TIF, com pelo menos, 300 dpi (ou
600 dpi se as imagens forem uma mistura de fotografias e
ilustrações em preto e branco). Contudo, atenção! Como
na editoração final dos trabalhos, o tamanho útil destinado
a uma figura de largura de página (duas colunas) é de
170 mm, para uma resolução de 300 dpi, a largura das
figuras não deverá exceder os 2000 pixels. Para figuras de
uma coluna (82 mm de largura), a largura máxima das
figuras (para 300 dpi), não deverá exceder 970 pixels.
Não fornecer imagens em arquivos Microsoft®
PowerPoint, geralmente geradas com baixa resolução, nem
inseridas em arquivos DOC. Arquivos contendo imagens em
formato Adobe® PDF não serão aceitos. Figuras deverão
ser fornecidas como arquivos separados (documentos
suplementares), não incluídas no texto do trabalho.
As imagens que não contiverem cor deverão ser salvas
como ‘grayscale’, sem qualquer tipo de camada (‘layer’),
como as geradas no Adobe® Photoshop, por exemplo. Estes
arquivos ocupam até 10 vezes mais espaço que os arquivos
TIF e JPG. A Acta Botanica Brasilica não aceitará figuras
submetidas no formato GIF ou comprimidas em arquivos
do tipo RAR ou ZIP. Se as figuras no formato TIF forem um
obstáculo para os autores, por seu tamanho muito elevado,
estas poderão ser convertidas para o formato JPG, antes da
sua submissão, resultando em uma significativa redução
no tamanho. Entretanto, não se esqueça que a compressão
no formato JPG poderá causar prejuízos na qualidade das
imagens. Assim, é recomendado que os arquivos JPG sejam
salvos nas qualidades ‘Máxima’ (Maximum).
O tipo de fonte nos textos das figuras deverá ser o Times
New Roman. Textos deverão ser legíveis. Abreviaturas
nas figuras (sempre em minúsculas) deverão ser citadas
nas legendas e fazer parte da própria figura, inseridas com
o uso de um editor de imagens (Adobe® Photoshop, por
exemplo). Não use abreviaturas, escalas ou sinais (setas,
asteriscos), sobre as figuras, como “caixas de texto” do
Microsoft® Word.
Recomenda-se a criação de uma única estampa,
contendo várias figuras reunidas, numa largura máxima de
175 milímetros (duas colunas) e altura máxima de 235 mm
(página inteira). No caso de estampa, a letra indicadora
de cada figura deverá estar posicionada no canto inferior
direito. Inclua “A” e “B” para distingui-las, colocando na
legenda, Fig. 1A, Fig. 1B e assim por diante. Não use bordas
de qualquer tipo ao redor das figuras.
É responsabilidade dos autores obter permissão para
reproduzir figuras ou tabelas que tenham sido previamente
publicadas.
2.3. Tabelas. As tabelas deverão ser referidas no texto com
a primeira letra em maiúsculo, de forma abreviada e sem
plural (Tab. 1, por exemplo). Todas as tabelas apresentadas
deverão, obrigatoriamente, ter chamada no texto.
As tabelas deverão ser seqüencialmente numeradas, em
arábico (Tabela 1, 2, 3, etc; não abrevie), com numeração
independente das figuras. O título das tabelas deverá
estar acima das mesmas. Tabelas deverão ser formatadas
usando as ferramentas de criação de tabelas (‘Tabela’)
do Microsoft® Word. Colunas e linhas da tabela deverão
ser visíveis, optando-se por usar linhas pretas que serão
removidas no processo de edição final. Não utilize padrões,
tons de cinza, nem qualquer tipo de cor nas tabelas. Dados
mais extensos poderão ser enviados como documentos
suplementares, os quais estarão disponíveis como links para
consulta pelo público.
Mais detalhes poderão ser consultados nos últimos
números da Revista.
