Monocots (short for Monocotyledons) are one of the major groups of flowering plants, characterised by having a single seed leaf – or cotyledon – that emerges when the seed germinates. Some of the largest families of flowering plants are Monocots, including the grasses, sedges, orchids, lilies and the gingers. So snowdrops and gingers have much in common despite one being highly familiar as the quintessential early spring flowers of every garden and the other the very image of exotic tropical rainforest flora. I first became aware of ginger through the ginger beer 'plant' on the kitchen windowsill of my childhood home. It fizzed contentedly when fed with root ginger and sugar and I am convinced that, to this day, I have never tasted the equal of our home-made supply! I didn’t know much about gingers until I began to work and travel as a botanist in the tropics. In Malawi, where there are many species of Costus, I began to appreciate just how difficult it is to make good herbarium specimens of gingers because of their very delicate flowers. Over the years my respect for ginger experts has grown – these are some of the most difficult plants to preserve. It’s not just the delicacy of the flowers, the leaves are often enormous and take up several pages in a plant press. One thing that is clear is that there are still many new species out there waiting to be discovered, described and named. There is an urgency to this work because of the threats to their natural habitats in the tropics and because so many members of the ginger The Royal Botanic Garden Edinburgh is a Charity registered in Scotland (No SC007983) and is supported by the Rural and Environment Research and Analysis Directorate.

As always, our research and conservation work on gingers is a collaborative effort with partners in other countries, including the Smithsonian Institution in the United States, as well as institutions in the tropical countries that are home to wild gingers. Gingers also rather nicely illustrate the way in which we coordinate with the Royal Botanic Gardens, Kew – sometimes working together and sometimes dividing the task between us. Monocots are a major focus at Kew but by mutual agreement the gingers are one group they do not study, so that our work complements their efforts on the other groups. We have long been famous for our work on Rhododendrons, now the story is out for another RBGE speciality.

The statue is in memory of Professor Douglas Mackay Henderson CBE, FRSE, VMH, who was the twelfth Regius Keeper of RBGE, from 1970 to 1987. He died in 2007 after a distinguished career which earned him the title Her Majesty’s Botanist in Scotland. The unveiling ceremony in September 2008 was attended by over 100 family, friends and former colleagues, including three successors as Regius Keeper (pictured above, left to right): Professor David Ingram; the current Regius Keeper Professor Stephen Blackmore and Professor John McNeill. D received VisitScotland’s coveted five star status, making it the first garden in Scotland to achieve this world-class recognition. The Garden, near Peebles, has reaped the benefits since the opening of its £1.6m visitor centre in May. Sandi Hellowell, VisitScotland's Regional Director, said: “It is credit to all involved. The five-star award really emphasises the time and effort that has gone into making the attraction world- class standard.” Regius Keeper Professor Stephen Blackmore added: “We cannot fail to be delighted. We have long believed the Garden itself was of world-class standard, but the upgraded facilities have allowed us to hugely improve our visitor offering”. Global index of plant and animal collections I n December 2007, RBGE embarked on a new project to help develop an internetbased index of the worlds’ biological collections of plants and animals. This Biological Collections Index (BCI) is being created in partnership with the Global Biodiversity Information Facility (GBIF) and Biodiversity Information Standards (TWDG). It is estimated that there are approximately 15,000 collections of biological artefacts in the world, including living specimens, illustrations, fossils, seeds and other materials. These collections are widely distributed around the academic and governmental institutions of all nations. It is intended that the index will provide a single point of access for researchers and governmental agencies seeking biodiversity materials. The first working version of the index was announced by RBGE’s Roger Hyam in October at the TDWG 2008 conference in Australia. It is available for use at www.BiodiversityCollectionsIndex.org/. With many other projects showing an interest in integrating with it, the index looks set to become a key feature of the global infrastructure of biodiversity information. Apple Day at the Garden T he first Apple Day Celebration to be held in the Garden drew over 1,000 visitors to a two-day event in October. In partnership with the Glasgow-based organisation The Children’s Orchard, the event showcased more than a hundred varieties of apple which grow in Scotland, including Edinburgh’s own James Grieve variety. Visitors could bring in their own apples to be pressed, or enjoy the pickings from RBGE’s own apple trees. Tasty treats were baked from RBGE’s apples by Edinburgh’s Manna House Bakery. It’s hoped that Apple Day will grow on this success with more celebrations next year. A world-first grant for botanical accountancy A lasdair Macnab, Director of Corporate Services at RBGE, has secured a prestigious first in the world of accountancy by gaining professional funding for research into strategic management of botanic gardens globally. Alasdair Macnab underwent a rigorous selection process from the Chartered Institute of Management Accountants (CIMA). It is the first time such backing has been granted to a botanic garden. Alasdair Macnab said his ambition was that this research would bring fresh insight into how botanic gardens, as not-for-profit organisations, could work efficiently as research institutes and how they might benefit from global coordination of certain activities. 4 | T H E B OTA N I C S w i n t e r 2 0 0 8 A renaissance of research into gingers has made RBGE a world-renowned centre for the study of this extraordinarily diverse family, as Anna Levin discovers. Main: A flower of the common ginger Zingiber officinale, with its more familiar rhizome – the root-like underground stem – and the end product: a gingerbread house. Photos by Jana Leong-Škorničková. Meet the relatives M ost of us only know one ginger, Zingiber officinale, and our encounters are limited to its spicy, root-like stem, crystallised and dipped in chocolate or ground into cakes and biscuits. We may have met some family members without realising they were related: cardamom and turmeric, used in Indian cookery, and ornamentals such as red ginger and Siamese tulip, which are increasingly popular in flower shops. But these are just a few representatives of a vast, diverse and often flamboyant family, with more than 1,500 species found mostly in tropical forests. For an introduction to this family closer to home, step into the steamy forest atmosphere of the Wet Tropics House, part of the Windows on the World tour of Edinburgh’s Glasshouses. Here the most famous ginger Zingiber officinale looks quite shrubby and inconspicuous among so many of its showier relatives. An enormous Etlingera from Sumatra takes centre stage, with startling flowers, thick towering stems and massive leaves reaching the roof. Close by is a red wine ginger Zingiber vinosum from Borneo, which has tiny, pale yellow flowers near the ground and takes its name from the claret-coloured underside of its leaves. Near the entrance to this house is Globba winitii, known as dancing ladies for its long dangling trails of yellow flowers suspended from purple bracts.

Photo by Jana Leong-Škorničková. What links these varied family members are two distinctive traits: a small flap of tissue called a ligule where the leaf joins the stem, and the pattern of the leaves arranged in two opposite ranks. Most leaves also contain ethereal oils, which give a distinctive aroma. These traits make gingers easily recognisable, yet within these traits the family displays extraordinary variety. Stems may be small and slender or tall and towering. Some leaves are huge and shining green, some intricately-patterned spears and others small shapes of dark, rich, velvet. And, the flowers range from big, bright and bold to downright bizarre, or tiny and delicate with an orchid-like beauty. The gingers on public display are just a small selection of RBGE’s Living Collection – most of which is kept behind the scenes in the Research Houses. These are used by RBGE staff and visiting scientists, together with an extensive collection of preserved specimens in the Garden’s Herbarium. Inside the Research House is a lush jungle of gingers of all shapes and sizes, some bearing surreallooking fruits, others with miniature flowers like tiny butterflies among the foliage. The plants here tell the story of ginger research at RBGE. The oldest ones date back to the 1960s when Bill Burtt, one of the Garden’s leading taxonomists, was exploring Sarawak on the island of Borneo. He was primarily looking for gesners but found gingers along the way. His Research Assistant Rosemary Smith wrote that “he had been intrigued by their appearance in the rainforest, particularly those species which produced their spectacular flowers at ground level, borne separately from the Gingers are the most conspicuous undergrowth in the rainforest and are both beautiful and useful. leaves.” Back in Edinburgh, the task began of identifying and naming the unknown species. “The ensuing plunge into the taxonomic history of the family found me floundering, while Bill tackled the nomenclatural tangles with relish,” wrote Rosemary. Nevertheless, she took on the bulk of this work and published extensively on gingers through the 1970s and 1980s. Today RBGE is one of the most important centres in the world for the study of gingers. The Research House is now crowded with an influx of new arrivals – the results of a resurgence of interest in gingers led by botanist Mark Newman. “Gingers are the most conspicuous undergrowth in the rainforest, and are both beautiful and useful,” says Mark. “Only three species are commonly used in this country, but people in the hill tribes of India and Asia use more than 300 species, for cooking, medicine and religious ritual.” Yet, scientifically, there is still a lack of basic information about many species of ginger. It is difficult to assess their conservation status, for example, because not enough research has yet been undertaken. “Gingers are difficult to collect and study,” Mark explains. “It is difficult to make good herbarium specimens: some species are huge, the inflorescence (flower head) is often slimy and the flowers are asymmetrical and so hard to press – so a beautiful, delicate specimen can become a brown squash on a herbarium sheet.” Much of the work today still focuses on identifying and naming species. “Historical confusion means that the 6 | T H E B OTA N I C S w i n t e r 2 0 0 8 taxonomy – classifying species – is difficult with gingers,” says Mark. “There may be 3,800 names for 1,500 species, yet one name for ten different species, so it is difficult to sort out the correct name. The study of chromosomes is among the tools used – each genus has its own basic number of chromosomes, so counting them can help aid identification.” Mark is working on a database of ginger species to enable scientists around the world to share information effectively. His own research currently focuses on a revision of the genus Globba, found throughout Cambodia, Laos, Thailand and Vietnam. This means finding out how many species there are, how to identify them, where they are distributed and whether they are threatened. Addressing these questions involves regular fieldwork in the rainforests of South-East Asia, where new species are being discovered. “Many forests are seasonal and the gingers come up in the rainy season, then disappear in the dry season,” says Mark. “They survive the dry season, and even forest fires, by storing moisture and energy in the rhizome – that’s the bit you see in the supermarket. Yet until the advent of tarmac roads it was difficult to travel in South-East Asia during the rainy season. There is now a broad network of such roads in Thailand, but not in Laos and Vietnam, so previously unknown species will be lurking there.” While many of the world’s ginger species are found in Asia, there are also some African plants in the Edinburgh Glasshouses. These are Aframomum, the largest of the four ginger genera found throughout tropical Africa. They were collected by David Harris, now RBGE Herbarium Curator, who was drawn into studying gingers when he realised how little was known about them. In the 1980s David was working as a botanical assistant with a gorilla research project in the Central African Republic. His task was to identify the plants that the gorillas were feeding on, including gingers which form an important part of their diet. He took plant specimens back to Kew Top, left to right: Torch ginger Etlingera elatior, photo by Jana Leong-Škorničková; Candy stripe turmeric Curcuma rhabdota, and Aframomum angustifolium, photos by Alex Wilson.

Photo by Jana Leong-Škorničková. to identify, but of the first 16 species he collected, he could only name four. “This flagged up the lack of information,” David says. “It was frustrating that I couldn’t provide the primatologists with the names of species.” David took up the challenge and embarked on a complete revision of Aframomum across Africa. This painstaking task involved borrowing all available specimens from herbariums around the world and steadily working through them, sorting them into species and plotting their locations across the African continent. Together with Research Assistant Alex Wortley, David has worked through about 4,000 specimens in this way. They have already made great progress, with over 70 species identified so far. “It is very satisfying to be giving information back and finally to be able to answer those questions, 20 years on,” he says. Many of the gingers in RBGE’s collection, including the vast Etlingera in the Wet Tropics House, were brought to RBGE by the Danish botanist and prolific collector Axel Dalberg Poulsen. Having studied gingers in the Amazon, Africa, Asia and the Pacific, Axel recently arrived in Edinburgh for an 18-month project to revise the Etlingera genus on the Indonesian island of Sulawesi, a region in which RBGE has made several collecting trips in the past. The project combines in-depth research using RBGE’s Living Collection, Herbarium and Library, with expeditions to the mountains of Sulawesi. “Nobody has worked on gingers there for 100 years, and so a lot of information T H E B OTA N I C S w i n t e r 2 0 0 8 | 7 is lost, out of date or inaccurate,” Axel explains. “It’s exciting to find new species but equally gratifying to put pieces of the jigsaw together. That’s the detective work of a botanist – it involves many languages, looking at the evidence, reading expedition reports and going back to collect in those locations.” Back in the Research House, Axel surveys rows of young Etlingera with pride. “I call them my toddlers,” he says, and describes the excitement of collecting seeds in the field and sending them to the Garden, then returning to RBGE himself to find young plants growing. “I’ve only seen these as enormous plants, and so I didn’t know what the babies looked like before now – I’m learning, seeing new details like the red tinge to the first leaves.” Important new discoveries happen here in the Research House as well as out in the field. Often botanists don’t know what they are collecting: they find an unknown species, collect seed or rhizome to send home, and must then wait – sometimes a few years – for the plant to grow and flower before it can be identified. This all depends on the knowledge and skill of RBGE's horticultural staff, some of whom have been an integral part of expeditions to Sulawesi in recent years, enabling them to glean valuable knowledge of conditions in the gingers’ natural habitat. “I remember coming across a new Etlingera species, growing in Top: Axel Dalberg Poulsen tends to his ‘toddlers’ at RBGE – as yet unidentified Etlingera species from Sulawesi.

Photo by Jana Leong-Škorničková. a big dell up in the mountains of northern Sulawesi,” says Horticulturist Steve Scott. “I scrambled down and took a bit of the rhizome. We never saw this plant again.” It is now flourishing back in Edinburgh. Nicknamed ‘rhubarb and custard’ because of its red and custardyellow flower, the species still hasn’t been named scientifically. “It’s great to bring back a plant and find that it is new to science,” says Steve. “We find new species on every trip.” Horticulturist Helen Yeats is currently responsible for the maintenance of the ginger collection, adjusting her daily routine through the seasons as the light and temperature change. “It’s a challenge!” she says. “In their natural habitat some of these gingers would experience warm days with quite intense sun, cold nights and regular light levels near the equator. We can’t replicate that – we can have 16 hours of light in the summer and not enough in the winter. Another challenge is the size – some gingers can reach 8 m tall and with so many new specimens arriving we are short of space.” “The wide variety makes them interesting. If I have a favourite it would be the genus Curcuma (turmeric), especially the candy stripe Curcuma rhabdota, it’s so gaudy like a surreal 1970s album cover!” She leads the way through the thicket of gingers in the Research House to find one of the last flowers before the deciduous Curcuma die back for the winter. It’s bold and bright among a fan of green foliage. Just like the research activities based on them, the gingers themselves are flourishing 8 | T H E B OTA N I C S w i n t e r 2 0 0 8 Jana Leong-Škorničková In February 2008, a Memorandum of Understanding was signed between RBGE and Singapore Botanic Gardens to facilitate a closer working relationship between the two Gardens. Jana Leong-Škorničková, a Senior Researcher at Singapore Botanic Gardens who works in collaboration with RBGE staff on the Zingiberaceae Resource Centre, explains her lifelong love of gingers. I fell in love with gingers as a ten-year-old. We visited the botanic gardens in Prague on a school trip and I remember the wild flora in the glasshouses. By then I already knew I wanted to be a tropical botanist but that was not on the agenda in communist Czechoslovakia. When you live in a country where you are not free you dream. I used to read books about people travelling in faraway forests. Everyone has childhood dreams and mine was to discover new species of plants or animals. The revolution happened before I went to university so at least we could travel. But when I said I wanted to study gingers, they just laughed at me. Above: Staff of RBGE and Singapore Botanic Gardens at the Ginger Garden after signing the Memorandum of Understanding between the two gardens. Below: Jana Leong-Škorničková searching for gingers in Sarawak. Right: Curcuma rubrobracteata the first new species Jana discovered, fulfilling a childhood dream. After 40 years of communism we had completely lost our link to tropical botany – very few teachers were old enough to remember the pre-communism era. But I managed to get a scholarship to study gingers in India as a part of my PhD. In India I finally achieved my childhood dream when I found a new Curcuma in Mizoram. I was so thrilled, completely on a high! I’m more used to it now – on most expeditions you find at least one new species, but there is a slow process of verification to discover if it has already been described or not. In 2001 I met a Singaporean, who became my husband five years later. I knew Singapore Botanic Gardens had a long history in studying gingers, and I was very excited to hear that a Ginger Garden was being created there. I started volunteering there from my very first visit, later I got a part-time job and then a full-time job, in between my PhD. The major issue in plant taxonomy is to give the correct name to the correct plant. (It’s like people – if you make a mistake in the names you can execute the wrong person!) Taxonomy is definitely still queen of sciences. We can’t do any conservation effort or biodiversity studies unless we know what we have in the remaining forests. The forests are being cleared very quickly so we need to act fast. But it’s difficult: to trace retrospectively the history of a name is no joke, because there are 200 years in between and plenty of people have expressed their opinions and diverted the story a little bit here and a little bit there. It takes time to untangle, sometimes your only clue is handwriting on an old herbarium sheet. Some people love to boast about their kids in front of everyone, and I’m just like that with gingers. Gingers are amazing and they are beautiful, which helps – you have to be in love with your subject. T H E B OTA N I C S w i n t e r 2 0 0 8 | 9 A day in the life… Fay Young finds RBGE’s Mairi Gillies busy preparing exhibitions for the opening of the John Hope Gateway in 2009. A round 8.45 am Mairi Gillies checks emails in her office at the top of Inverleith House. After that it can be hard to track her down. Between trips up and downstairs “fielding more email” she could be busy in the laundry (that windowless space next to Inverleith House) casting moulds of plant specimens, in the Exhibition Hall checking the current exhibition, or out in the borders hunting for fungi. Every day brings a different creative challenge for the young artist turned horticulturist, who is now Curator of Exhibitions for the John Hope Gateway, working against the clock to coordinate and complete the exhibitions which will open with the building next year. “There are basically three parts to my job,” says Mairi. The daunting detail shows in a blaze of pink, green and yellow Post-it® notes stuck to the wall above her desk. That’s pink for temporary exhibitions, yellow for ongoing events in the Exhibition Hall and green for semi-permanent exhibitions. “I’m a very visual person,” she says laughing. “This is how I get my head round things.” With the show safely installed in the Exhibition Hall (Close by Allan Pollok-Morris runs until 11 January), Mairi is now concentrating on the green Post-it®. At the time of this interview she is roughly half-way through collecting and preserving specimens for the semipermanent display in the new building. When the weather is good she is likely to start the day in the Garden competing with squirrels for prize specimens. “It’s an extreme environment out there,” she says, “I’ve had squirrels stealing from my bag.” From algae to orchids, the taxonomic family tree of plants will be set out in 96 bell jars of different shapes and sizes, which is why her desk is surrounded by samples of ferns, fungi and seaweeds along with plastic moulds, glycerine and sugary crystals of silica gel. None of this seems daunting to an artist whose work has always been inspired by nature. “I work very closely with science and horticulture, but I do have a fair bit of artistic licence,” says Mairi who came to the Garden in 2003 as a volunteer when she was at Edinburgh Art College and returned with a degree in sculpture a year later to take the HND in Horticulture with Plantsmanship. She successfully applied for her present job after 18 months as a member of the horticulture staff working on Vireya rhododendrons. There are other days when Mairi meets artists and craftsmen commissioned to work with wood from the Garden’s wych elm for next year’s first temporary exhibition. Then there’s the prospect of relocating Images of the Garden, the annual exhibition of work by students and tutors of the adult education programme, which has been such a popular feature in the Exhibition Hall. “We’ll be moving from a very adaptable white cube to a space with lots of glass and a curved wall; it’s going to be interesting.” And there simply isn’t room here to mention all the imaginative plans for new collaborative projects with schools, community groups and other research organisations to communicate the cultural and natural heritage of Scotland. Right now there are plants to collect and preserve. Once the fungi season is over it will be time for mistletoe. 1 0 | T H E B OTA N I C S w i n t e r 2 0 0 8 A celebration of snowdrops Photos: Snowdrops flourish below Dawyck's towering trees (main and facing page, top) and Logan's exotic Chusan palms (facing page, below). With a special conference and a festival full of arts and crafts activities, RBGE is making the most of its snowdrop collections this year. T H E B OTA N I C S w i n t e r 2 0 0 8 | 1 1 T iny yet tough, snowdrops pierce the hard winter ground with their spear-shaped leaves before revealing the exquisite beauty of their shining white bells. Spreading in clumps and clusters through woodlands and gardens, they reflect the early sunlight bringing the hope of new life and the promise of spring. No wonder snowdrops are among the best-loved of Britain’s flowers and have been collected, cultivated and celebrated for hundreds of years, resulting in endless varieties today. Once known as the Candlemas bells, snowdrops were viewed as an emblem of purity and were often planted in monasteries and churchyards. RBGE will be taking part in Scotland’s 2009 Snowdrop Festival, in which gardens throughout Scotland open early in the year to encourage visitors to get out and admire the drifts of snowdrops in the clear winter light. Now in its third year, the Snowdrop Festival is run by VisitScotland and showcases the best snowdrop gardens, woodlands and estates across the country. The festival was the inspiration of Lady Catherine Erskine of Cambo Estate, home to Scotland’s National Collection of Snowdrops. “At the height of the season the snowdrops at Cambo are breathtaking,” she says. “There are carpets of snowdrops as far as the eye can see, clinging to the sides of the burn, tumbling down the slopes. “The simple beauty and tenacity of snowdrops is very endearing. However foul the weather, up they come and remain looking white and beautiful for several weeks. Flowering in the darkest days of winter, the sight of them is uplifting.” The idea of a snowdrop festival came about when Lady Erskine was asked by a group of Dutch visitors to arrange a tour of Scottish snowdrop woods and realised that there was no easy way to find out about visiting snowdrop gardens and woods. “In Scotland we have the best snowdrop woods in Britain,” she says. “There is great potential to encourage visitors from near and far to get out and about at snowdrop time. Part of my mission with snowdrops is to encourage more garden visitors to Scotland and to raise the profile of gardens as a good day out. The interesting thing about snowdrop visitors is that they are not your ‘normal’ garden visitors – very often they are families wanting an outing at a dull time of the year and quite a number have never visited a garden before. If we can capture their interest then it has to be good.” Three of RBGE’s Gardens will be taking part in this year’s festival. Dawyck is renowned for its stunning drifts of snowdrops, which cover the banks of the Scrape Burn and spread far up the hillside. Logan is opening on Sundays throughout the festival to allow visitors to enjoy the carpet of snowdrops among a wide variety of early flowering rhododendrons, camellias and other exotic plants in this subtropical garden. A specialist collection of snowdrops is scattered throughout the Edinburgh Garden, especially in the Rock Garden and woodland areas. Snowdrop-themed events will take place at the Edinburgh Garden, including guided walks, family science and craft activities. A special collection of historic photographs and botanical illustrations from RBGE archives will be on display in the Library Foyer. February will also see a gathering of ‘galanthophiles’ – snowdrop enthusiasts – at the Edinburgh Garden, with a Snowdrop Conference, held in association with the Cambo Estate. This will feature a programme of talks on specialist snowdrops and their collectors, as well as guided tours of the collections in the Edinburgh Garden. “I hope by organising the Snowdrop Conference we will put Scotland on the ‘snowdrop map’ and attract visitors from England and Europe,” says Lady Erskine.

J oin us at the Botanics for RBGE’s fourth Green Christmas celebrations which take place during the first three weekends in December from 10.30 am to 3.00 pm. The Edinburgh Garden’s Exhibition Hall will be a hub of activity for all ages with the main attraction being the opportunity to visit Green Santa in his magical grotto, and get a lovely present to take home. There is also the chance to try out a range of creative crafts in the lead up to Christmas, with activities such as creating your own Christmas wreaths using recycled and natural materials with the Art-tastic team; making your own winter-inspired story book with the Garden Rangers; or learning some of the techniques used to create botanical illustrations with Sunday Science. You can find out more about the plants that are around us at Christmas-time – in the Garden, in the wild, and in traditional Christmas cooking. You may even be lucky enough to hear some of our carol singers! Let the Talking Trees storytellers feed your imagination with tales of far away and long ago, deepest winter and Christmas-time. The Festive Feast exhibition in the Library Foyer will offer visitors the opportunity to view a selection of books and images from the Library and Archives, all with a festive connection. All this must be reason enough to come in from the cold and warm your hands and heart with seasonal fun at the Botanics!

BGE’s new one-day Science Taster Workshops launched at the Edinburgh Garden in September and are proving very popular. The workshops allow an insight into some of the techniques used in botanical research, and some of the different ways in which RBGE’s work contributes to the global conservation of plants. There are five one-day workshops to choose from. These include ‘3 Collections in 1’, an explanation of how RBGE’s three collections – the Living Collection, the Library and the Herbarium – are maintained and how they link together, and ‘Phylogenetics for Beginners’, which will explore the evolutionary history of plants. Emily Wood, the Short Course Co-ordinator, explains: “The aims of the workshops are to provide an opportunity for people to discover some of the scientific techniques behind the plant research at RBGE. “Some workshops focus on techniques which course participants can use in their own research, such as the skills practised in ‘Plants Under the Microscope’, while others offer a deeper understanding of essential botanical themes, such as plant classification and evolution in ‘Getting to Grips with Plant Names’ and ‘Phylogenetics for Beginners’.” To see a full list of the one-day workshops available, and to download a booking form, visit www.rbge.org.uk/education or contact the Education Office on 0131 248 2937.

Close R BGE’s autumn exhibition by Scottish photographer Allan Pollok-Morris has generated a huge amount of interest among visitors, including fellow photographers, artists and garden enthusiasts. Allan has a real eye for the quirkier aspects of Scottish gardens, and the exhibition draws out the unique nature of home-grown horticulture that thrives on good plantsmanship, rain and eccentricity. All the photographs in the exhibition are included in a new hardback book Close: A journey in Scotland, a celebration of some of our famous and not-so-famous gardens and garden-art, from Charles Jencks’ Garden of Cosmic Speculation to Alec Finlay’s Letterboxes. Fascinating, intriguing and compelling, the journey is one that armchair gardeners will find inspiring and immensely satisfying. Close is at RBGE’s Exhibition Hall, at Edinburgh Garden, until 11 January, admission free. Two Voices III P art of a series of six exhibitions describing RBGE’s Gardens through colour photographs by blind artist Rosita McKenzie, accompanied by tactile interpretations by Camilla Adams and audio commentaries. This exhibition is the third in the series and focuses on horticulture at the Edinburgh Garden. Two Voices III/Horticulture Behind the Scenes runs at Inverleith House until 8 February 2009. Tuesday to Sunday, 10 am to 3.30 pm, admission free. Above: The Nursery at the Edinburgh Garden. Photograph by Rosita McKenzie. Not His Now I n January, RBGE’s Library opens the covers on a selection of books from its collections to find out a little bit about who owned them before and the unique ways in which some owners marked their ownership. Not His Now: Inscriptions, Bookplates and Annotations in Some RBGE Library Books runs from 6 to 30 January in the Library Foyer at the Edinburgh Garden, admission free. W hen it comes to making Scottish cities more enjoyable and safer places for cycling we can learn a lot from the experience of the Danes. The exhibition Dreams on Wheels looks at cycling and cycle-ways in Copenhagen, which has been rated the most cycle-friendly city in Europe. RBGE is in the centre of a network of carfree cycle routes in the city, and we are delighted to host this touring exhibition from the Danish Cultural Institute. As well as offering an insight into city planning for a more sustainable and pollution-free environment, the exhibition includes a real bonus for cycling enthusiasts – a collection of unique bicycles from some of Denmark’s top design teams. Those of us who are of the opinion that the bicycle represents the pinnacle of human invention and are interested in innovative, functional and beautiful Danish design, are getting very excited about this exhibition, which has previously toured Australia and will arrive in Edinburgh in the spring. Dreams on Wheels is at RBGE’s Exhibition Hall, Edinburgh Garden, 24 January to 21 March, admission free. 1 4 | T H E B OTA N I C S w i n t e r 2 0 0 8 “A dazzlingly diverse world through the microscope” Retired doctor and RBGE Member Jack Oliver has explored new depths in the world of aquatic plantlife, as he tells Anna Levin. T hrough his medical career, Jack Oliver had focused on children damaged by their parents and carers, mainly with brain and visual injuries following maltreatment and neglect. On retirement, he was looking for an activity which offered a complete break from this “depressing topic” and “emotionally-charged scientific endeavour” and so returned to botany, in which he had excelled as a teenager. He pursued his new focus with zeal, joining the Botanical Society of the British Isles and co-founding a Botanical Society in Wiltshire. He also started a small arboretum and, inspired by a lecture on the RBGE-based International Conifer Conservation Project, joined as a Friend of the Garden and is growing small numbers of ten threatened conifer species. For his own research, he took up the challenge of studying water plants, noting that little had been recorded of the plants on and under Wiltshire’s rivers, ponds and canals. Exploring the “dazzlingly diverse world through the microscope”, he became interested in the minute algae which he saw surrounding the plants’ roots. Mostly these were free-floating or were growing attached to the roots. Some roots, however, were sufficiently transparent to see inside them and Jack Oliver was intrigued to see “green blobs” actually inside the root tissue itself. “This was all new to me and not described in any of my botany textbooks,” he says. “Eventually, some of the microphotos of root tissues were sufficiently distinctive to reveal that algae had infiltrated and invaded the living roots of four duckweeds and six other water plant species.” He sent his pictures to algae specialist Hans Sluiman at RBGE, who suggested that these were original observations. A summary of Jack Oliver’s findings has been published in The Phycologist, the newsletter of the British Phycological Society which aims to promote the study of algae. A champion of botanical research, Jack Oliver feels more resources should be directed to biological investigation. “The variety of botanical and zoological life – especially at microscopic level, with all the concomitant complex biochemistry – is astounding,” he explains. “A handful of soil or cupful of pondwater probably has more diversity than could be found in the rest of our solar system outside our green world. However, billions have been spent on space exploration and physics such as CERN atom smashers, hundreds of times more than is spent studying our own Earth’s unique and complex biology.” For more information about becoming a Member, contact the Membership Office on 0131 248 2868 or visit www.rbge.org.uk/support-us Above: Jack Oliver (top) and two microscope photos showing algae deep inside the roots of duckweed specimens. A special feature of this algal species are bristle-like structures, which are thought to be involved in the uptake of nutrients from the surrounding water. Photos by Jack Oliver. Eden founder addresses RBGE Patrons T im Smit (pictured, left, centre) provided an inspirational speech at RBGE's Patrons' Dinner in October. Renowned for his work on the restoration of 'The Lost Gardens of Heligan', he also co-founded the Eden Project in Cornwall. Sponsored by Life PD Homes and catered by Prestige Scotland, the event included a champagne reception and a dinner in the Caledonian Hall in the Edinburgh Garden. T H E B O T A N I C S WINTER 2 0 0 8 | 1 5 Greenfingers We are more familiar with the ginger family in our food and drink, but members of the Zingiberaceae can also make attractive garden plants – even in Scotland, as RBGE Garden Supervisor Pete Brownless explains. T Above: The newly refurbished bothy is opened by Lady Margaret Elliot (far right) as RBGE’s Regius Keeper Professor Stephen Blackmore and Viv Sutherland of Life PD Homes look on. From old bothy to new facility T he old bothy at the RBGE’s Nursery has been transformed into a spacious and comfortable facility for participants of the ongoing Horticultural Therapy programme, thanks to sponsorship from Life PD Homes, one the companies developing property adjacent to the Garden and sponsor of Patrons’ events for two years. Upgraded to include a meeting room, changing facilities, lockers, kitchen and disabled toilet, the bothy was officially opened by Lady Margaret Elliot during a reception for Patrons and Horticultural Therapy volunteers on Monday, 29 September. Also present was Duncan Sutherland, Director of Life PD Homes and a descendant of RBGE’s first Regius Keeper James Sutherland (RK: 1699 - 1715). During the evening, Regius Keeper Professor Stephen Blackmore presented certificates to volunteers for achievements including long service, completion of the Discovery level of the John Muir Award and the Certificate in Practical Horticulture. The volunteers gave demonstrations of various aspects of their work, including apiary care, phenology, bird- and bat-box construction, cuttings and tool cleaning. Finally, the Garden’s Patrons were each given a herb, grown by the volunteers, as a memento. he crystallised ginger which we often enjoy at Christmas is just one of the treasures produced by members of the ginger family, Zingiberaceae. A recipe for Indian food, for example, would not be complete without the spiciness of cardamom (Elettaria sp.) and turmeric (Curcuma sp.). The family is distributed throughout tropical Africa, tropical and temperate Asia and the Americas, so you probably would not expect to be able to grow any gingers in your Scottish garden. Some gingers, however, are surprisingly hardy. For the woodland garden, the genus Roscoea provides attractive herbaceous plants with a cult status to rival trilliums. Roscoea enjoy our wet summers and are happy in light shade. Roscoea purpurea is perhaps the easiest to grow; it reaches about 35 cm tall and produces a succession of flowers in early summer. It can be divided in the autumn after leaves have died down. For a warm sunny site, try Hedychium gardnerianum. Its flamboyant yellow flowers are borne on top of spikes of luxuriant tropical foliage reaching 120 cm tall in late summer. Plant the rhizomes deep, adding as much wellrotted compost and organic matter as possible. Illustration: Roscoea purpurea, Curtis’s Botanical Magazine, Plate 463, Vol. 78, year 1852. Cautleya spicata makes a spectacular plant in a large pot of summer bedding, with flamboyant yellow-orange flowers held in bright red bracts. It comes from the Himalayas and has broad green canna-like leaves growing 45 cm tall. Edge the pot with the tubers of the architectural-leaved love plant Oxalis triangularis. Keep the pot frost free over winter. Throughout the winter you can enjoy the warmth of Edinburgh’s tropical Glasshouses to hunt for spicy gingers. At other times of the year explore the gingers in the Woodland Garden area in Edinburgh and at Logan Botanic Garden. 1 6 | T H E B OTA N I C S w i n t e r 2 0 0 8 Royal Botanic Garden Edinburgh Open daily (except 25 December and 1 January) Inverleith Row, Edinburgh, EH3 5LR Tel: 0131 552 7171 Email: info@rbge.org.uk Admission to the Garden is free; charge applies to the Glasshouses. • Benmore Botanic Garden The Botanics Shop now brought direct to your door!
