Micropropagation of Heritage Rhododendron Collections at the Royal Botanic Garden Edinburgh
Get PDFThe most recent efforts at micropropagation of Rhododendron species started at the Royal Botanic Garden Edinburgh in 2013. This paper outlines the methods and practices adopted, and highlights some of the problems and pitfalls encountered throughout the process. At the close of 2017 the first plants propagated using in vitro techniques were planted at Benmore Botanic Garden in Argyll, Scotland
Bogor Botanic Gardens
Get PDFBogor Botanic Gardens (BBG) was established in 1817 and is the oldest botanic garden in South East Asia. The garden has long been a centre for scientific research and has been the founding institution of a number of other research centres in Indonesia, particularly in the life sciences. The garden initially covered 47 ha but has expanded over the years and is now 87 ha. It has evolved over its 200-year history from a collection of economically valuable plants to the multi-faceted institute it is today, undertaking activities in plant conservation, research, education, ecotourism and environmental services. In recent years, it has strengthened its role in plant conservation through the establishment of 32 new botanic gardens across Indonesia. These new gardens are managed by local government and universities and supervised by BBG. In its bicentenary year, 2017, BBG organised a number of activities, programmes and celebrations and these are highlighted in thisarticle
The Living Collection at the Royal Botanic Garden Edinburgh Illustrates the Floral Diversity in Streptocarpus (Gesneriaceae)
Get PDFA visual summary of the floral types present in the diverse genus Streptocarpus is given along with descriptions of the different categories. We categorised the species and defined seven types and six sub-types. The use of a comprehensive and well-curated living collection for the study of floral diversification is presented and its use for interpretation and education discussed
The History of the Walled (Formal) Garden at Benmore Botanic Garden
Get PDFThe 2.02 ha site containing the Category B listed Walled Garden at Benmore is currently the subject of a major redesign proposal and active fundraising programme. The purpose of this article is to raise the profile of the project by investigating and highlighting the historical development of the site. This retrospective study is also intended as a support to contemporary redevelopment plans and as a demonstration of how the past underpins and informs the future.I am frankly and absolutely for a formal garden … It is a small piece of ground enclosed by walls … There is not the least attempt to imitate natural scenery (Phillpotts, 1906, p. 54)
A Survey of Bryophytes and their Management in the Ferns and Fossils House at the Royal Botanic Garden Edinburgh
Get PDFThis paper is derived from a research project produced during the author’s studies for a BSc in Horticulture with Plantsmanship at the Royal Botanic Garden Edinburgh (RBGE). The body of work represents findings from a floristic survey of naturally occurring bryophytes in the Ferns and Fossils House at RBGE. This site merited close study due to the known presence of at least two southern hemisphere species along with many native species. Horticultural staff were interviewed about current bryophyte management within glasshouse displays. Recommendations are made for raising the status of bryophytes in botanic gardens and expanding the scope of living collections.
This report includes an introduction, literature review, methodology, survey results, interview summary and conclusion
Cultivation of Orites Myrtoideus : The First 12 Months
Get PDFOrites myrtoideus (Poepp. & Endl.) Engl. is an evergreen shrub in the family Proteaceae, endemic to the Andes of both Chile and Argentina. With a small distribution and increasing risks, direct conservation action has been recommended. Ex situ cultivation and subsequent translocation of populations may be an option for the conservation of this species. In recent documented history this species has been grown ex situ on only a small number of occasions. One plant was grown outside at Benmore Botanic Garden for a period of five years and another has been grown at the Royal Botanic Garden Edinburgh as part of the Arid Lands collections. A better understanding of its cultivation requirements has been deemed necessary before ex situ collections can be established.This study aims to give a broad overview of the germination and first 12 months of cultivation of this taxon with the aim of informing future ex situ cultivation and subsequent restoration initiatives
The 10th Flora Malesiana Symposium
Get PDFThe 10th Flora Malesiana Symposium was held at the Royal Botanic Garden Edinburgh (RBGE) between 11 and 15 July 2016 and was attended by 185 researchers from 25 countries. Over five days, taxonomists, horticulturists and conservationists came together to present and discuss their research on the plant diversity of the Malesian region. Over 160 presentations were given and a series of very popular workshops was run
Strategy to Conserve Maximum Biodiversity of Limestone Flora in Peninsular Malaysia
Get PDFThe need to exploit limestone products for national development impacts on the conservation of rare and endangered limestone species. To minimise this impact it is necessary to identify which of the 570 limestone outcrops have high conservation importance and whether they have narrowly endemic and/or endangered limestone species. In the absence of detailed checklists for each outcrop, the Gesneriaceae is selected as being biodiverse on limestone, being well collected and outstanding in the number of endemic species and/or species restricted to limestone for mapping. Of the 210 species in the 25 genera of Gesneriaceae in Peninsular Malaysia, 42 species belonging to the genera Damrongia Kerr ex Craib, Emarhendia Kiew, A.Weber & B.L.Burtt, Epithema Blume, Microchirita (C.B.Clarke) Yin Z.Wang, Monophyllaea R.Br., Ornithoboea Parish ex C.B.Clarke, Paraboea (C.B.Clarke) Ridl., Senyumia Kiew, A.Weber & B.L.Burtt and Spelaeanthus Kiew, A.Weber & B.L.Burtt grow on limestone hills. Of these 42 species, 28 are endemic and 16 are restricted to a single or adjacent hills. Mapping their distribution shows that in common with other families there are three distinct phytogeographical provinces (the Northern Province, Perak Province and the Asian Intrusion) but that the narrowly endemic species do not cluster on particular hills, nor does their distribution coincide with those of other narrowly endemic species in other families. This illustrates that a network comprising a large number of hills, not only those within the three provinces but also all those harbouring narrowly endemic species that are at risk of extinction if not conserved, is necessary to maximise conservation of the biodiversity of the limestone flora
Recent Taxonomic Notes and New Distribution Localities of Podocarpus Pers. Species in the Philippines
Get PDFThe taxonomy of plants provides a great contribution to understanding diversity and conservation. This study provides additional taxonomic notes on Podocarpus species in the Philippines using newly collected specimens to determine new distribution localities of these species. This study recognises ten species of Podocarpus in the Philippines. Notable results of this study are: (1) the existence of variable leaf forms in P. pilgeri Foxw. correlated to the type of habitat where the species occurs; (2) variable leaf forms and sizes observed in mature and juvenile leaves of all species; (3) support of the sectional arrangement of P. palawanensis de Laub. & Silba; (4) differences between the wild and cultivated representatives of P. costalis C.Presl based on leaf characters; (5) new distributions for P. ramosii R.R.Mill, P. pilgeri, P. costalis, P. neriifolius D.Don, P. rumphii Blume and P. polystachyus R.Br.; (5) no support for the inclusion of P. neglectus Blume and P. hookeri de Laub. as new species found in the Philippines; and (6) comprehensive examination and identification of numerous herbarium specimens and recently collected material
Pollination, Mating System, Phenology and Characterisation of Medinilla multiflora Merr. (Melastomataceae) on Mt Makiling, Philippines
Get PDFAn investigation into the reproductive biology of Medinilla multiflora Merr. (Melastomataceae) from Mt Makiling, Luzon, is presented. This includes a morphological and distributional examination of the population on the mountain, the documentation of reproductive phenological patterns, a study of the mating system and observations of biotic interactions. Measurements were made of trait variability, reproductive phenology was characterised from field and herbarium observations, stigmatic receptivity was tested by counting pollen germination, insect exclusion and hand-pollination experiments helped determine the mating system and field observations recorded the identity and behaviour of floral visitors. Significant reproductive morphological differences were found between described populations. This identified a need for the recognition of this diversity and further delimitation of the Medinilla multiflora species complex. Although Medinilla multiflora produced flowers and fruit year-round, the population also exhibited cycles of increased reproduction most likely initiated by seasonal low temperatures. Medinilla multiflora was found to require pollination but not cross-pollination. Two major peaks in stigmatic receptivity occurred throughout the day and the majority of pollen was found to be viable. Generalist bees proved to be the primary pollinators of the study population and were most active in the morning depending on weather conditions. Generalist pollinators and self-compatibility are advantageous traits for establishment and persistence in isolated mountain habitats; however, losses of this habitat due to climate change could have profound consequences for the future success of Medinilla multiflora
