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.

Colorado Grasses is an illustrated guide to 350 species of grasses growing in Colorado. Most of the species are also found in Wyoming and the southern Rocky Mountains. Colorado Grasses features illustrated keys to species, detailed descriptions, numerous illustrations, distribution maps, and an illustrated glossary. Grass morphology is explained and illustrated.

This systematic treatment of Colorado grasses will help students, naturalists, botanists, ecologists, agronomists, range scientists, and other interested readers identify and learn about this unique and economically important plant family. Grasses of Colorado describes all grasses known to occur in the state outside of cultivation: more than 300 native, introduced, naturalized, and adventive species. Colorado's elevation range of more than 11,000 feet creates a wide variety of habitats that supports a spectacular diversity of grasses. With 335 known species, Colorado has one of the most diverse and extensive grass floras in the United States. Comprehensive coverage, useful keys, and detailed species descriptions in Grasses of Colorado will make this volume the standard reference for years to come. Robert B. Shaw provides overviews of Colorado's physiography and ecoregions and introduces the grass plant in plain, enjoyable text. He includes a checklist of Colorado grasses, a bibliography, and a glossary of terms that may be unfamiliar to nonspecialists. Line drawings, state distribution maps, and habitat notes for each species enable accurate plant identification, familiarity with regional ecogeography, and increased understanding of plant ecology of the Rocky Mountains. A monumental accomplishment certain to become the standard work on the subject, Grasses of Colorado synthesizes existing literature and incorporates recent scientific findings to offer a complete, current reference.

"Beautiful and expansive…in Johnstun's Let the Wild Grasses Grow, Colorado has a successor to Kent Haruf." —SEAN PRENTISS, author of Finding Abbey Let the Wild Grasses Grow chronicles the lives of Della Chavez and John Cordova, childhood friends separated by a tragic accident, who find each other again during World War II after leading separate lives of struggle through the Great Depression, the Dust Bowl, and, for John, abuse at the hands of his grandfather. This sweeping American love story celebrates the power of home landscapes, family heritage, and first love.
