"This impressive, streamlined new field guide to plants of California deserts is based on The Jepson Manual but is truly a handbook to be carried in the field. It offers new introductory discussions, many new illustrations, revised user-friendly keys, updated distribution information, flowering times... and handsome color photos of many species. This marvelous book demonstrates that our deserts are not barren wastes but treasure houses filled with an abundance of floristic riches."-Robert Ornduff, author of Introduction to California Plant Life; "An invaluable companion to those who delight in the unusual and beautiful plants of these scenic areas."-Peter H. Raven, Director, Missouri Botanical Garden; "This much-needed volume incorporates new information about the status and range of many California desert plants. This book will facilitate access to information about our deserts, and will lead to increased respect and attention to them. We warmly welcome it."-Jake Sigg, President, California Native Plant Society
