Classification of orchids based on evolutionary history, determined by morphology and the latest DNA data. This third volume desribes the remaining 105 genera of subfamily Orchidoidae and all 15 genera of subfamily Vanilloidae. Comprehensive treatments are provided for each genus, which include complete nomenclature, description, distribution (with map), anatomy, physiology, cytogenics, phytochemistry, phylogenetics, pollination, ecology, and economic uses. Cultivation notes are included for those genera known to be in hobbyist collections. All genera are illustrated with line drawings and colour photographs.
1. Orchidoideae (Part 2)D: Chloraeeae
2. Vanilloideae Vanilleae
"Genera Orchidacearum is the first work to treat the whole of the orchids in a modern form based on molecular data from nearly all of the more than 800 genera. [...] As in the former volumes, layout is very clear [...] The photographs are without exception good and informative, in many cases excellent [...] The distribution maps are very clear, and easy to interpret. [...] excellent book [...] it is an absolute requirement for the professional orchidologist as a reference work. It fills a gap because no other up-to-date systematic treatment of Orchidaceae down to generic level is available in English, and I am quite sure that no comparable work will be published during the next few decades."
