Following an overview of Vietnam's geology, climate zones, vegetation, and slipper orchid genera, international botanists present the first detailed description of the country's 22 lovely but highly endangered Paphiopedilum species and natural hybrids. Entries cover their morphology, ecology, history, in situ flowering period, habitat, and status. The final section treats conservation efforts. Includes color photographs, botanical drawings, distribution maps, and climatological data graphs. Annotation (c) Book News, Inc., Portland, OR (booknews.com)
