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 Published and unpublished sources of East African records. 6.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. -
The Ethnobotany of South African Medicinal Orchids ⁎ M
South African Journal of Botany 77 (2011) 2–9 www.elsevier.com/locate/sajb Review The ethnobotany of South African medicinal orchids ⁎ M. Chinsamy, J.F. Finnie, J. Van Staden Research Centre for Plant Growth and Development, School of Biological and Conservation Sciences, University of KwaZulu-Natal Pietermaritzburg, Private Bag X01, Scottsville 3209, South Africa Received 22 July 2010; received in revised form 14 September 2010; accepted 28 September 2010 Abstract Orchidaceae, the largest and most diverse family of flowering plants is widespread, with a broad range of ethnobotanical applications. Southern Africa is home to approximately 494 terrestrial and epiphytic orchid species, of which, 49 are used in African traditional medicine to treat cough and diarrheal symptoms, madness, promote conception, relieve pain, induce nausea, and expel intestinal worms and for many cultural practices. The biological activity and chemical composition of South African medicinal orchid species are yet to be explored fully. In this review we highlight the potential for pharmacological research on South African medicinal orchid species based on their traditional medicinal uses. © 2010 SAAB. Published by Elsevier B.V.

Cytotaxonomy of the Monopodial Orchids of the African and Malagasy Regions
Cytotaxonomy of the monopodial orchids of the African and Malagasy regions J. C. Arends & F. M. Van der Laan Department of Plant Taxonomy and Plant Geography, Agricultural University, Gen. Foulkesweg 37, 6700 ED Wageningen, The Netherlands Abstract The three subtribes which are recognized within the tribe Vandeae are represented in the tropical African and Malagasy regions. All taxa of the Vandeae have a monopodial growth habit. The first subtribe, Sarcanthinae, is mainly Asian-Australasian, but a few of its species occur in Madagascar and in Africa. The other two subtribes, Angraecinae and Aerangidinae, are both represented in the latter two regions. The Angraecinae ischaracterize d by the presence of a short rostellum, but this iselongate d in the Aerangidinae. According to earlier authors there is a correlation between presence of the short rostellum and a basic chromosome number of x= 19i nth e Angraecinae, and between the presence of an elongated rostellum and a basic number of x = 25 in the Aerangidinae. The results presented in this paper are placed in perspective with the chromosome numbers recorded by other authors. From the resulting chromosome number survey it appears that only part of the Angraecinae (Aeranthes, several species of Angraecum. Cryptopus and Jumellea) have a basic number of x = 19; some members of the Angraecinae (other species of Angraecum) were found to have a basic number of x = 21,24 and 25. The Aerangidinae is not characterized by a single basic number of x= 25 but by aserie s ranging from x = 23t o x= 27,o f which x= 23,24 and 25ar e the most frequent. -

Aerangis Hariotiana by Brenda Oviatt and Bill Nerison Photgraphs and Drawing by Brenda Oviatt
COLLECTor’s item Aerangis hariotiana by Brenda Oviatt and Bill Nerison Photgraphs and drawing by Brenda Oviatt The Aerangis Formerly Known as ... Aerangis hariotiana can produce a plethora of long-lasting, brightly colored flowers. Grower: Botanica Ltd. 590 ORCHIDS AUGUST 2016 WWW.AOS.ORG WHAT’S IN A name? This plant is better known by its former name; Microterangis hariotiana or even Chamaeangis hariotiana. Prior to that, it was also called Saccolabium hariotianum, and was first described in 1897 as Mystacidium hariotianum. Names aside, this is a charming, floriferous, colorful semiminiature orchid and we are excited to write about it; it’s a rewarding orchid to grow. Our specimen was beginning to bloom and we were sure we could get some excellent photos of this extraordinary plant. Mature, multigrowth plants will produce many spikes and are very long-lasting (read the culture section to find out why no such photo is included in this article). We began doing research about the history of the species and found that confusion seems to be prevalent with regard to it, especially on the Internet. We decided to look at the plant from a different angle for this article. First, some back- ground. The ge- nus Chamaeangis was established by Rudolf Schlechter in 1915 and, even at that point, he divided it into two Brenda Oviatt and sections based on Bill Nerison differences in the flower structure: Chamaeangis and Microterangis. He noted that there were enough differences between the sections that section 1 Microterangis might be elevated to genus level at some point (which was done in now called Diaphananthe odoratissima. -

Abstract Nine plants specimens of an apparently new Tridactyle species were collected in Gabon and Equatorial Guinea. They have an erect habit and a particular leaf shape which makes the species unique in the genus. The flowers and inflorescences share the general morphology of Tridactyle tridactylites, one of the most frequently collected species of Tridactyle in Central Af- rica. Four other Tridactyle taxa possess a 3 to 6 cm long inflorescence and a labellum with entire side lobes, and one species, Tridactyle stevartiana, has leaves of similar width and length. We here show that these new 9 specimens represent a new species, described as Tridactyle minutifolia. -

A Key and Check List to Kenya Orchids
A KEY AND CHECK LIST TO KENYA ORCHIDS By G.C: COpley, E.M. Tweedie and E.W. Carroll Drawings by E.M. Tweedie J.E.Afr.Nat.Hist.Soc. Vol.XXIV No.4 (108) January 1964 Introduction This key represents an attempt by three keen orchid-hunters to place before others equally ignorant of systematic botany what it is hoped will prove a fairly comprehensible way of identifying some of the orchids they will find in Kenya. It may be as well to warn beginners in this hobby that though they will find few specimens spectacular enough to be worth a place in a fancier's orchid-house, they will come across many which, when in flower, well deserve an honoured position in any drawing-room. We will have attained our object in constructing this artificial key if a few others are not only persuaded by it to share the enjoy• ment we derive from recognising, drawing and photographing, these plants, but if they also add to our knowledge of them by collecting and preserving new species. The Botanist in Charge, E.A. Herbarium, Nairobi, will name specimens of orchids sent to him, and advise the beginner on the method of pickling and pressing orchid specimens. The key has been revised by E.M. Tweedie up to September 1962, and her thanks are due to Mr. V.S. Summerhayes of the Herbarium, Royal Botanic Gardens, Kew, for all his kind help and advice. Also to the staff of the E.A. Herbarium for their help in many ways, especially with the check list; to Dr. -
