1500 orchid species are profiled in this authoritative, detailed, and carefully researched encyclopedia. Infinitely varied and hugely interesting, these strikingly beautiful plants are sumptuously illustrated with over 1000 photographs in a reference that no orchid lover can afford to be without. Isobyl la Croix is a scientist, plant hunter, and horticulturalist; her deep passion for orchids informs the plant selection and adds depth to the plant descriptions. The cultivation advice includes information about the orchid's native habitat—including elevation, geography, and climate. Recent developments in DNA analysis have led to some surprising findings with regard to the relationships between orchids, and the author has undertaken an extensive effort to bring all orchid names up-to-date to reflect the latest scientific thinking and taxonomy. From Acampe to Zygostates, no other serious reference approaches the depth and authority of this remarkable book.
