4This book is designed to serve as a reference work, classroom textbook, and field manual for botanists, naturalists, and students interested in learning to identify and learn about the distinguishing features of grasses of the northeastern United States. Included are more than 380 species of grasses that have been documented as occurring in the region. The volume contains 246 range maps and 269 line drawings that clarify descriptions used in the keys and illustrate characteristics of the various kinds of grasses. Dennis Magee also provides a description of each genus and species along with synonyms and habitats. For anyone interested in an up-to-date treatment of the grasses of greater New England, this volume will be an invaluable resource. It is the only comprehensive technical guide devoted exclusively to the grasses of this region and presents a wealth of information in a precise, clear format. The geographic scope of the work extends from the Canadian border south through Long Island and west to the Hudson River. But given the considerable overlap with the grass flora to the adjacent north, south, and west, the book will also be useful beyond New England and the bordering New York counties. The volume includes an illustrated glossary of essential terms and concepts and a "how to use this manual" section. A CD-ROM with a multiple-entry identification guide, and hundreds of accompanying photographic images of individual species, is provided in a sleeve inside the back cover of the book.
