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
This work is actually the definitive encyclopedia of United States grass life. Compiled from the U.S. National Herbarium collection, the largest of its kind in the world, it is the only complete manual of U.S. grasses available and one of the basic reference works on U.S. plant life. It catalogs and describes in detail all 1,398 numbered species in 169 numbered genera found in this country, plus 120 species in 16 genera of the so-called “waifs.” Professor Hitchcock is the former Chief Botanist in charge of systematic agrostology for the U.S. Department of Agriculture, by whom the work was originally published, and an internationally known authority. The heart of the book is its detailed descriptions of the family of grasses, the two main subfamilies, the tribes, genera, and species. Quick finding keys are provided for the identification of tribes and genera. Each of the species is given thorough botanical description, including various aspects of its morphology — size, shape, form of culms, blades, panicles, spikes, and flowers — and height, proper planting season, and range of distribution are noted. The Manual also outlines the common uses to which grasses are put and discusses in general terms their distribution, classification, nomenclature, and common names. The 1,199 drawings make identification of any grass species found in the United States a virtual certainty. The appended synonymy of alternate names for each species provides an authoritative taxonomy, eliminating confusion. The nature lover with no more technical equipment than a keen eye can use this manual with profit, for a glossary of botanical terms is included. Naturalists, botanists, agriculturists, and horticulturists will find it valuable as a field and research guide to virtually all the grasses that grow in this country.
