EPIDENDROIDEAE (примитивные трибы – Neottieae, Vanilleae, Gastrodieae, Nervilieae) Summary. The article continues serial publication of illustrated critical taxonomical survey of orchids in the flora of Vietnam. This part of the monograph includes taxonomical treatment of so-called primitive tribes (Neottieae, Vanilleae, Gastrodieae, Nervilieae) of the largest subfamily Epidendroideae (17 genera and 41 species in Vietnam); besides, some corrections and additions to first and second parts of the monograph are included. Identification keys, valid name, necessary synonyms, type material citation, short description, data on ecology and distribution, as well as a list of studied voucher specimens for each species are provided. Mentioned species are illustrated with original line drawings and color photographs. Two new nomenclature combinations are proposed, namely Cyrtosia faberi (Rolfe) Aver., and C. falconeri (Hook. f.) Aver. A new genus Miguelia Aver. with 2 species – M. somai (Hayata) Aver. and M. annamica (Gagnep.) Aver. is established. Description of a new species – Peristylus tenuicallus Ormerod. discovered by P. Ormerod on the base of his studies of AMES Herbarium is also presented. Key words: Orchidaceae, flora of Vietnam, keys for identification. Аннотация.

Orchids need to select an appropriate fungus among diverse soil fungi at the germination stage. However, there is limited understanding of the process by which orchids recruit fungal associates and initiate the symbiotic interaction. This study aimed to better understand this process by focusing on the seed coat, the first point of fungal attachment. Bletilla striata seeds, some with the seed coat removed, were prepared and sown with symbiotic fungi or with pathogenic fungi. The seed coat-stripped seeds inoculated with the symbiotic fungi showed a lower germination rate than the intact seeds, and proliferated fungal hyphae were observed inside and around the stripped seeds. Inoculation with the pathogenic fungi increased the infection rate in the seed coat-stripped seeds. The pathogenic fungal hyphae were arrested at the suspensor side of the intact seeds, whereas the seed coat-stripped seeds were subjected to severe infestation.

The diversity of wild orchids in the southern slope of Mount Merapi, Yogyakarta, Indonesia eight years after the 2010 eruption. Biodiversitas 21: 4457-4465. The ecosystem of the slopes of Mount Merapi is mountain tropical forest which is frequently affected by volcanic activities. The dynamics of the volcano affect the diversity and abundance of orchids in the ecosystem. Tritis is an area included in the Turgo Hill of the southern slope of Mount Merapi and is under the management of Mount Merapi National Park. The ecosystem in Tritis area classified as lower mountain forest and it has been affected by Mount Merapi eruption. This study aimed to do an inventory of orchid species in Tritis to know the diversity and abundance of orchids that exist in this area.

  • Phylogeny, Character Evolution and the Systematics of Psilochilus (Triphoreae)
    THE PRIMITIVE EPIDENDROIDEAE (ORCHIDACEAE): PHYLOGENY, CHARACTER EVOLUTION AND THE SYSTEMATICS OF PSILOCHILUS (TRIPHOREAE) A Dissertation Presented in Partial Fulfillment of the Requirements for The Degree Doctor of Philosophy in the Graduate School of the Ohio State University By Erik Paul Rothacker, M.Sc. ***** The Ohio State University 2007 Doctoral Dissertation Committee: Approved by Dr. John V. Freudenstein, Adviser Dr. John Wenzel ________________________________ Dr. Andrea Wolfe Adviser Evolution, Ecology and Organismal Biology Graduate Program COPYRIGHT ERIK PAUL ROTHACKER 2007 ABSTRACT Considering the significance of the basal Epidendroideae in understanding patterns of morphological evolution within the subfamily, it is surprising that no fully resolved hypothesis of historical relationships has been presented for these orchids. This is the first study to improve both taxon and character sampling. The phylogenetic study of the basal Epidendroideae consisted of two components, molecular and morphological. A molecular phylogeny using three loci representing each of the plant genomes including gap characters is presented for the basal Epidendroideae. Here we find Neottieae sister to Palmorchis at the base of the Epidendroideae, followed by Triphoreae. Tropidieae and Sobralieae form a clade, however the relationship between these, Nervilieae and the advanced Epidendroids has not been resolved. A morphological matrix of 40 taxa and 30 characters was constructed and a phylogenetic analysis was performed. The results support many of the traditional views of tribal composition, but do not fully resolve relationships among many of the tribes. A robust hypothesis of relationships is presented based on the results of a total evidence analysis using three molecular loci, gap characters and morphology. Palmorchis is placed at the base of the tree, sister to Neottieae, followed successively by Triphoreae sister to Epipogium, then Sobralieae.

  • Do Orchids Grow in Hawaii? and How!
    Do Orchids Grow in Hawaii? And How! SYNOPSIS This is an historical sketch of the Saga of Orchids in Hawaii. The sequence of events from the incidental introduction of species by the Agriculturists for the Sugar Industry; to their efforts in propagation and culture, hybridizing and germination; to the development of personal nurseries to commercial ranges; and ultimately to the creation of a viable orchid industry, re­ cognized world wide; to the natural formation of orchid societies staging of orchid shows; and finally to the introduction of a system of orchid judging , should bring interesting reading to orchidists, amateur and professional alike.
