The first, is a description of the physical and biological setting, and the second, a section with keys to families and species accounts arranged by major groups and thenalphabetically listed by family. Using these criteria, theauthors describe some 285 species of trees found in the state of Sonora, Mexico. Webster,Herbarium, University of California, Davis., "What is a tree? According to Felger, Johnson and Wilson, it is a plant that if climbed by medium- sized primates will not collapse, a plant with a single trunk of about 10 cm in diameter that extends for over one metre above the ground and is at least 5 m tall. The Trees of Sonora is a beautifully produced volume in terms oftypography, reproduction of illustrations, and editing. Although we have seen a lot of books on palms in recent years, thisone gives an intimate perspective on the Sonoran palm flora, with usefulfeatures such as a diagram comparing leaf structure in Brahea, Sabal, andWashingtonia.

The descriptive species accounts include common names, indigenous names, and synonyms, detailed botanical descriptions, ecological and geographic data, geographic ranges, natural history, economicuses, and, in many cases, other information such as horticultural uses and conservation status. Two hundred eighty-five species of native and naturalized trees are covered,featuring extensive identification keys and illustrations, most of them newly produced for this book. The introductory chapter contains biotic and climatic information and an analysis of the geographical distributions of the trees of a state that is poorly known biologically. Felger is the recognized expert in the area, and the book contains an enormousbody of information nowhere else obtainable. ![]() Thus, this book will be important to biologists in regions well outside of the area covered. The majority ofthe trees in this semi-arid region are at their northern limits in the Americas in this state and many range to South America. The definitive treatment of the trees and tree-like plants of Sonora, a remarkably diverse and biologically important region, ranging from some of the driest and hottest areas in North America to cool, temperate woodlands and the northernmost tropical regions in the New World. ![]()
