To understand almost any part of the tropical rain forest's fabulously complex web of life, one must first learn to identify a bewildering array of plants. Alwyn Gentry's landmark book, completed just before his tragic death in 1993, is the only field guide to the nearly 250 families of woody plants in the most species-rich region of South America. As a consummate field researcher, Gentry designed this guide to be not just comprehensive, but also easy to use in rigorous field conditions. Unlike many field guides, which rely for their identifications on flowers and fruits that are only present during certain seasons, Gentry's book focuses on characters such as bark, leaves, and odor that are present year-round. His guide is filled with clear illustrations, step-by-step keys to identification, and a wealth of previously unpublished data. All biologists, wildlife managers, conservationists, and government officials concerned with the tropical rain forests will need and use this field guide. Alwyn Gentry was one of the world's foremost experts on the biology of tropical plants. He was senior curator at the Missouri Botanical Garden, and was a member of Conservation International's interdisciplinary Rapid Assessment Program (RAP) team, which inventories the biodiversity of the most threatened tropical areas. From 1967 to 1993 he collected more than 80,000 plant specimens, many of them new to science.

A pocket guide to identifying native ferns that grow in the U.S. Midwest and Northeast, and eastern Canada. Like other plant guides in the "Finders" series, "Fern Finder" is a dichotomous key, which leads the user step-by-step through a series of choices to the species being identified. Heavily illustrated with line drawings.

This beautifully illustrated guide identifies nearly 300 common plants in Indiana's most prominent ecosystem—the Eastern Deciduous Forest. For ease of identification, the plants are arranged by flower color or growth form, providing a convenient way to distinguish a great majority of plants in any given woodland. Generous treatment is given to all major vascular plant groups of the forest, such as wildflowers, ferns, shrubs, trees, grasses, and sedges. Michael A. Homoya not only helps with identification, but also offers information on a plant's habitat, flowering period, familial relationships, biology, and connections to Indiana. For the garden enthusiast and habitat restorer, there is a section on landscaping and natural community restoration using native forest plants. A portion of the proceeds from each sale of this book go to the Indiana Department of Natural Resources for land protection and stewardship.
