An Introduction to the Epiphytic Orchids of East Africa
Sphyrarchynchus sp. Cyrtorchis crassifoHa Schltr. AN INTRODUCTION TO THE EPIPHYTIC ORCHIDS OF EAST AFRICA. By W. M. MOREAU AND R. E. MOREAU. C()IYl,tents. 1. Introduction. 2. Nomenclature and classification. 3. General ecology. 4. The orchid flower. 5. Published and unpublished sources of East African records. 6. Tentative field key to the genera. 7. Annotated check-list of species. 1. INTRODUCTION. Over fifteen thousand species of orchids have been described, the vast majority of them tropical, and the greater part of them epiphytic, that is, normally growing on trees without deriving sustenance from them. But little more than ten per cent of the majestic total belong to Tropical Africa and moreover, so far as is known at present, within that area ground orchids predominate over epiphytic in the proportion of more than three to one. There is reason to believe that these figures are a reflection rather of our ignorance than of the truth. Because the Tropical African epiphytic orchids are not characterised by the magni• ficence and opulence of those of other regions, they have not attracted the commercial collector and certainly are most imperfectly known. Yet the local orchids display a delightful diversity of adaptation and of form. None are flamboyant, but many are beautiful, some are exquisitely dainty and a few are bizarre. They appeal to the same feelings and are capable of arousing the same enthusiasms as succulents or alpine plants. Moreover, anyone who takes the comparatively little trouble required to collect and grow them has the additional satisfaction of knowing that he is contributing to scientific knowledge. -
Phylogenetic Placement of the Enigmatic Orchid Genera Thaia and Tangtsinia: Evidence from Molecular and Morphological Characters
TAXON 61 (1) • February 2012: 45–54 Xiang & al. • Phylogenetic placement of Thaia and Tangtsinia Phylogenetic placement of the enigmatic orchid genera Thaia and Tangtsinia: Evidence from molecular and morphological characters Xiao-Guo Xiang,1 De-Zhu Li,2 Wei-Tao Jin,1 Hai-Lang Zhou,1 Jian-Wu Li3 & Xiao-Hua Jin1 1 Herbarium & State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, P.R.

China 3 Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Menglun Township, Mengla County, Yunnan province 666303, P.R. China Author for correspondence: Xiao-Hua Jin, [email protected] Abstract The phylogenetic position of two enigmatic Asian orchid genera, Thaia and Tangtsinia, were inferred from molecular data and morphological evidence. An analysis of combined plastid data (rbcL + matK + psaB) using Bayesian and parsimony methods revealed that Thaia is a sister group to the higher epidendroids, and tribe Neottieae is polyphyletic unless Thaia is removed. Morphological evidence, such as plicate leaves and corms, the structure of the gynostemium and the micromorphol- ogy of pollinia, also indicates that Thaia should be excluded from Neottieae. Thaieae, a new tribe, is therefore tentatively established. Using Bayesian and parsimony methods, analyses of combined plastid and nuclear datasets (rbcL, matK, psaB, trnL-F, ITS, Xdh) confirmed that the monotypic genus Tangtsinia was nested within and is synonymous with the genus Cepha- lanthera, in which an apical stigma has evolved independently at least twice. -
Generic and Subtribal Relationships in Neotropical Cymbidieae (Orchidaceae) Based on Matk/Ycf1 Plastid Data
LANKESTERIANA 13(3): 375—392. 2014. I N V I T E D P A P E R* GENERIC AND SUBTRIBAL RELATIONSHIPS IN NEOTROPICAL CYMBIDIEAE (ORCHIDACEAE) BASED ON MATK/YCF1 PLASTID DATA W. MARK WHITTEN1,2, KURT M. NEUBIG1 & N. H. WILLIAMS1 1Florida Museum of Natural History, University of Florida Gainesville, FL 32611-7800 USA 2Corresponding author: [email protected] ABSTRACT. Relationships among all subtribes of Neotropical Cymbidieae (Orchidaceae) were estimated using combined matK/ycf1 plastid sequence data for 289 taxa. The matrix was analyzed using RAxML. Bootstrap (BS) analyses yield 100% BS support for all subtribes except Stanhopeinae (87%). Generic relationships within subtribes are highly resolved and are generally congruent with those presented in previous studies and as summarized in Genera Orchidacearum. Relationships among subtribes are largely unresolved. The Szlachetko generic classification of Maxillariinae is not supported. A new combination is made for Maxillaria cacaoensis J.T.Atwood in Camaridium.

Orchids: 2017 Global Ex Situ Collections Assessment
Orchids: 2017 Global Ex situ Collections Assessment Botanic gardens collectively maintain one-third of Earth's plant diversity. Through their conservation, education, horticulture, and research activities, botanic gardens inspire millions of people each year about the importance of plants. Ophrys apifera (Bernard DuPon) Angraecum conchoglossum With one in five species facing extinction due to threats such (Scott Zona) as habitat loss, climate change, and invasive species, botanic garden ex situ collections serve a central purpose in preventing the loss of species and essential genetic diversity. To support the Global Strategy for Plant Conservation, botanic gardens create integrated conservation programs that utilize diverse partners and innovative techniques. As genetically diverse collections are developed, our collective global safety net against plant extinction is strengthened.

Studies of West Malesian Agrostophyllum Blume (Orchidaceae)
Taiwania, 57(3): 251-262, 2012 Studies of West Malesian Agrostophyllum Blume (Orchidaceae) Paul Ormerod P.O. Box 8210, Cairns 4870, Queensland, Australia. Email: [email protected] (Manuscript received 6 March 2012; accepted 20 March 2012) ABSTRACT: Studies of West Malesian material of the genus Agrostophyllum reveals that three previously described species should be treated as new synonyms of earlier named entities, namely A. arundinaceum Ridl. (= A. cyathiforme J.J.Sm.), A. mearnsii Ames (= A. globiceps Schltr.) and A. wenzelii Ames (= A. glumaceum Hook.f.). However A. formosanum Rolfe is found to be a good species, distinct from A. inocephalum (Schauer) Rchb.f. On the other hand five new taxa have been recognised and are proposed here, namely A. asahanense, A. boeeanum, A. galeandrae, A. maliauense and A. pseudolaxum. KEY WORDS: Malesia, Agrostophyllum, new species. INTRODUCTION (Holotype: AMES!). The genus Agrostophyllum Blume currently Affinis A. djaratense Schltr. sed sepalis brevioribus contains about 102 species (new taxa included) (2.75-3.80 vs. 5 mm), epichilo ovato-suborbicularis, distributed from the Seychelles to Samoa.

Distribution of Vascular Epiphytes Along a Tropical Elevational Gradient: Disentangling Abiotic and Biotic Determinants
www.nature.com/scientificreports OPEN Distribution of vascular epiphytes along a tropical elevational gradient: disentangling abiotic and Received: 23 June 2015 Accepted: 16 December 2015 biotic determinants Published: 22 January 2016 Yi Ding1, Guangfu Liu2, Runguo Zang1, Jian Zhang3,4, Xinghui Lu1 & Jihong Huang1 Epiphytic vascular plants are common species in humid tropical forests. Epiphytes are influenced by abiotic and biotic variables, but little is known about the relative importance of direct and indirect effects on epiphyte distribution. We surveyed 70 transects (10 m × 50 m) along an elevation gradient (180 m–1521 m) and sampled all vascular epiphytes and trees in a typical tropical forest on Hainan Island, south China. The direct and indirect effects of abiotic factors (climatic and edaphic) and tree community characteristics on epiphytes species diversity were examined. The abundance and richness of vascular epiphytes generally showed a unimodal curve with elevation and reached maximum value at ca. 1300 m. The species composition in transects from high elevation (above 1200 m) showed a more similar assemblage. Climate explained the most variation in epiphytes species diversity followed by tree community characteristics and soil features. Overall, climate (relative humidity) and tree community characteristics (tree size represented by basal area) had the strongest direct effects on epiphyte diversity while soil variables (soil water content and available phosphorus) mainly had indirect effects. Our study suggests that air humidity is the most important abiotic while stand basal area is the most important biotic determinants of epiphyte diversity along the tropical elevational gradient. Understanding the mechanisms of species distributions at different spatial scales remains a central question of community ecology and biogeography1. -
