Orchids are found from England to Israel, not just in tropical areas. In this English update of the 2005, 2001, and 1994 editions published by Delachaux and Nestlé, Paris, botanist Delforge (adviser to the World Conservation Union) incorporates newly discovered species in the Mediterranean and adjacent regions, advances from genetics and biochemistry, and enough taxonomic changes to stress both amateur and professional botanists. He introduces orchid evolution, taxonomy, anatomy, lifestyle, nomenclature and conservation issues. The compact identification guide includes accounts of some 520 species and varieties keyed to a map and depicted in 1,270 color photographs and line drawings, plus further reading and a glossary. Some species, e.g., calypso, are also found in North America. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
