Book Description
"While emphasizing scientific accuracy, the book is written in an accessible style. Felger's observations and knowledge of plant ecology, geographic distribution, evolution, ethnobotany, plant variation and special adaptations, and the history of the region provide botanists, naturalists, ecologists, conservationists, and anyone else celebrating the desert with readable, interesting, and important information."--BOOK JACKET.

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
The Baboquivari Mountains, long considered to be a sacred space by the Tohono OÕodham people who are native to the area, are the westernmost of the so-called Sky Islands. The mountains form the border between the floristic regions of Chihuahua and Sonora. This encyclopedic work describes the flora of this unique area in detail. It includes descriptions, identifications, ecology, and extensive etymologies of plant names in European and indigenous languages. Daniel Austin also describes pollination biology and seed dispersal and explains how plants in the area have been used by humans, beginning with Native Americans. The term Òsky islandÓ was first used by Weldon Heald in 1967 to describe mountain ranges that are separated from each other by valleys of grassland or desert. The valleys create barriers to the spread of plant species in a way that is similar to the separation of islands in an ocean. The 70,000-square-mile Sky Islands region of southeastern Arizona, southwestern New Mexico, and northwestern Mexico is of particular interest to botanists because of its striking diversity of plant species and habitats. With more than 3,000 species of plants, the region offers a surprising range of tropical and temperate zones. Although others have written about the region, this is the first book to focus exclusively on the plant life of the Baboquivari Mountains. The book offers an introduction to the history of the region, along with a discussion of human influences, and includes a useful appendix that lists all of the plants known to be growing in the Baboquivari Mountain chain.
