For the untrained observer, it can be quite a challenge to sort out the many trees that make up a stand of older forest in, say, New England or the Ozarks. This well-illustrated guidebook, covering 364 species, comes to the rescue with photographs organized in several ways: by, for example, the shape of the leaf or needle, by the fruit, by the flower or cone, and by autumn coloration. Following one visible characteristic or another, the reader can narrow the range of possibilities, then turn to an informative text that describes a tree's physical characteristics, habitat, and range. Many of the species covered are relatively rare, such as the "stinking cedar" of the Georgia-Florida border; others are locally abundant, such as the paper birch of the boreal forest, used to make ice-cream sticks; still others, such as the smooth sumac, are widespread. The guidebook also covers ornamentals introduced from other continents, such as the Chinese privet and Mahaleb cherry. --Gregory McNamee
