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.

The rapid disappearance of tropical forests is widely recognized as a crucial problem for the world's environment, yet little is known about these complex ecosytems. In this book, experts on the four most thoroughly studied rainforests in Central and South America--Manaus, Brazil; Manu Park, Peru; Barro Colorado Island, Panama; and La Selva, Costa Rica--compare the flora, fauna, and ecological characteristics of these forests. This assemblage of reliable data, available for the first time, will be an invaluable resource for researchers and students.
