Orchidaceae: Illustrations and Studies of the Family Orchidaceae, Issuing from the Ames Botanical Laboratory North Easton, Massachusetts (Classic Reprint) by Oakes Ames (Paperback / softback, 2015)
Excerpt from Orchidaceae Illustrations and Studies of the Family Orchidaceae, Issuing From the Ames Botanical Laboratory North Easton, Massachusetts The division of the genus Dendrochilum into five subgenera by Pfitzer and Kranzlin* is based primarily on peculiarities of the vegetative structure and secondarily on characters of the gystemium and labellum. The spirit of this treatment is in full accord with the views clearly expressed by Pfitzer in his Entwurf einer naturlichen Ardnung der Orchideen (1887), where he says that the vegetative parts of the Orchidaceae are the most reliable for a natural classification of the genera, and that the floral parts, being of a less stable nature, are t to be relied on to any great extent, if we except the larger divisions of the family. A profound kwledge of the morphology of the Orchidaceae is, of course, indispensable in all critical work tending toward a rational classification. Without it, serious blunders must of necessity creep in and vitiate results. The vegetative parts of orchids, however, are frequently the most puzzling to interpret correctly in a system of classification based in the main upon them, and have led to unfortunate errors in judgment where the genus Dendrochilum is concerned.
