As yet, a comprehensive natural classification of the orchids is not available, due in part to their bewildering diversity and parallelism, and also to botanical neglect. Although much work is needed before a fully natural classification can be achieved, this book provides a valuable contribution to the on-going discussions. The author's clear manner of writing, and his acknowledged expertise in this subject, make the chapter on classification of special interest. His work delimits several major natural groups and emphasises areas needing further study, particularly among the more primitive groups. Information on orchid chromosome numbers is brought together and a new interpretation of this data provided. Novel information on pollination is also presented. A list of generic names and important synonyms is given, along with approximate numbers of species in each genus. Dr Dressler has been awarded the 1994 Henry Allan Gleason Award by the New York Botanical Garden for Phylogeny and Classification of the Orchid Family. The award is presented annually for an outstanding publication in the fields of taxonomy, plant ecology, and plant geography.

The first field guide to the orchids of Costa Rica and Panama, this book is lavishly illustrated with 240 stunning color photographs and 229 line drawings. It contains keys to all the orchid genera in the region and most of the orchid species. To make it possible for nonbotanists to identify at least the genus of the orchids, Robert L. Dressler emphasizes features that can be readily seen with the naked eye or a hand lens.Written in a friendly and accessible style, this guide begins with succinct descriptions of the geography, climate, and vegetation of Costa Rica and Panama, and includes appropriate comments on the peoples and cultures of the area. A discussion of orchid structure and ecology follows. The identification keys are preceded by instructions for use, and a general key directs the user to the appropriate chapter, where condensed descriptions and additional keys narrow the choices for the plant's identity. Dressler avoids complex terminology where possible and supplies a glossary of technical terms that will be helpful to those unfamiliar with botanical vocabulary. A short appendix describes how to prepare orchids for study and summarizes laws that affect plant collectors, and another lists the authors of species names used in the guide.Reflecting the author's deep and broad knowledge of the orchids of tropical Latin America, this field guide is certain to prove valuable to botanists, field biologists, orchid hobbyists and tourists interested in natural history.
