Orquídeas de Costa Rica / Orchids of Costa Rica. Vol. 3

168 pp., illustrations, bibliography, index. In English and Spanish. "The orchid family, whose scientific name is Orchidaceae, is the most numerous of all the world's plants, with nearly 20,000 species. Costa Rica is no exception, since orchids are the largest plant family in the country with between 1,300 and 1,400 known species. This is the volume 3 of a 5-volume series of field guides on Costa Rica's orchids. This volume covers the genera Epidendrum and Oerstedella. The series provides a tool for the visual identification of most species. Each species is illustrated with one or several photographs of the flowers and other important details, such as their growth habit and color variations. The main purpose of this series of guides is to promote the conservation of native orchid populations, which are in danger of becoming extinct due to large-scale extraction.".
