Orchideenatlas

"The third edition of this definitive handbook of orchid cultivation includes major revisions in both text and illustrations. It adds 24 pages of color photographs--bringing the total number of species illustrated to 864--and 62 line drawings. The sections on taxonomy have been substantially expanded to include updated treatments of orchid biology, diversity, and classification, and descriptions of 140 genera and more than twice that number of species have been added."--Amazon.
