Book Description
Grasses are the world’s most important plants. They are the dominant species over large parts of the earth’s land surface, a fact that is reflected in the many different words that exist for grasslands, words such as prairie, veldt, palouse, and pampas to mention just a few. As a group, grasses are of major ecological importance, as soil binders and providers of shelter and food for wild animals, both large and small. Some grasses, such as wheat, rice, corn, barley, rye, tef, and sugar cane are major sources of calories for humans and their livestock; others, primarily bamboos, are used for construction, tools, paper, and fabric. More recently, the seed catalogs that tantalize gardeners each winter have borne witness to an increasing appreciation of the aesthetic value of grasses. The Manual of Grasses for North America is designed as a successor to the classic volume by Hitchcock and Chase. It reflects current taxonomic thought and includes keys, illustrations, and distribution maps for the nearly 900 native and 400 introduced species that have been found in North America north of Mexico. In addition, it presents keys and illustrations for several species that are known only in cultivation or are of major agricultural significance, either as progenitors of bread wheat and corn or as a major threat to North American agriculture because of their ability to hybridize with crop species. The Manual of Grasses for North America is a major reference work for grasses that will retain its value for many years.

Book Description
Grasses are among the most ubiquitous plants on the planet. They inhabit a wide geographic range and are found in a variety of natural habitats. The small parts of the grass flower and specialized terminology, however, can make identifying grasses a challenging endeavor. Sarah Chamberlain’s Field Guide to Grasses of the Mid-Atlantic makes identification simpler for everyone—regardless of their previous botanical knowledge. Featuring an easy-to-use dichotomous key, this is a user-friendly guide to more than 300 types of grasses found from the Blue Ridge Mountains and southern plains to the Appalachians and the Allegheny Plateau. Each major entry contains detailed species diagrams as well as common names, habitats, and distribution. The book’s opening sections outline the parts of grass flowers and describe stem, leaf, and sheath characteristics. With a wealth of illustrations, instructions on how to use the key, and a glossary of terms, Field Guide to Grasses of the Mid-Atlantic is an indispensable reference for naturalists and conservationists, botanists, land management professionals, and students and scholars of mid-Atlantic flora.
