For centuries orchids have been among the most popular of plant families, with thousands of species and hybrids cultivated worldwide for the diversity, beauty, and intricacy of their flowers. The Genera Orchidacearum series represents a robust and natural classification of the orchids, something that has eluded plant scientists and orchid enthusiasts for years. The editors, who are all distinguished orchid specialists, incorporate a wealth of new DNA data into a truly phylogenetic classification, identifying the areas and taxa that merit additional work. To this end, they have invited several international specialists to contribute in their particular areas of expertise. Each volume provides comprehensive coverage of one or two orchid subfamilies, and the series as a whole will be an indispensable reference tool for scientists, orchid breeders, and growers. Orchidaceae is the largest monocotyledon family and perhaps the largest plant family in terms of number of species, approximately 25,000. Although the fossil record is limited, active molecular research in recent years has unravelled many of the complexities and phylogenetics of this cosmopolitan plant family. This sixth and final volume treats 140 genera in tribes Dendrobieae and Vandeae of the largest subfamily, Epidendroideae, including some of the showiest orchids often used in hybridizing. Comprehensive treatments are provided for each genus, which include complete nomenclature, description, distribution (with map), anatomy, palynology, cytogenetics, phytochemistry, phylogenetics, pollination, ecology, and economic uses. Cultivation notes are included for those genera known to be in hobbyist collections. Genera are beautifully illustrated with line drawings and colour photographs. An Addendum updates a few generic accounts published in past volumes. A cumulative glossary, list of generic synonyms with their equivalents, and list of all series contributors round out this final volume in the series.
A valuable contribution to the on-going discussions on evolution within the Orchid family. Dressler's work delimits several major natural groups and emphasises areas needing further study.
This highly informative and nicely illustrated book is the first of its kind to cover all of the vandoid orchid genera in Asia. The content includes; what defines an orchid of monopodial/vandaceous growth; the tremendous variation in plant and flower habit including the considerable array of perfumes; notes and observations on recently proposed generic changes based on first generation molecular technology; the main chapter on 'Selected Genera and Species of the Asian Vandoid Orchids' covers 72 genera and more than 180 species with text descriptions defining each genus and the included reprasentative species with their plant and flower habit/s, countries of distribution and notes on habitat and altitudinal range enhanced with very nice colour photos. The following chapters include miscellaneous notes and other observations on the genus Renanthera accompanied by the proposal of 1 new section and 2 new species which are nicely described and illustrated accompanied further with notes and technical drawings on the little known entity Renanthera moluccana and other species, including the unique pollination syndrome of the sister genus Renantherella and its type species R. histrionica. Further, an overview of the genus Ornithochilus is provided with the proposal of 1 new section, the description of 1 new species and 2 new combinations enhanced with many technical drawings of all 9 species and 3 of those are also included in the main chapter with colour photographs. Another 23 new names, combinations and typification's are presented in the genera Arachnis, Cleisocentron, Cleisostoma, Gastrochilus, Grosourdya, Holcoglossum, Pennilabium and Robiquetia, closing with nomenclatural changes in Amesiella. The final chapter to conclude this nicely illustrated book is an annotated check list of all vandoid orchid genera known to occur in Asia including those tentatively accepted pending the outcome of a comprehensive reanalyses of the subtribe Aeridinae with 'Next Generation Sequencing' molecular technologies. Among the more than 240 quality colour photos are some of the rarest species of vandaceous orchids to occur in Asia. This quality book is a must have for all plant species enthusiasts and anyone with an interest or passion for the vandaceous orchids. ISBN 978-0-9876206-4-4 Soft Cover, Full Colour, 200 pages:
