“California’s extraordinary flora is described in contemporary detail in this handy volume, which should prove an inspiration to all of those interested in these plants, their habitats, and their importance to a state richer in botanical diversity than any other part of the United States. This is a thorough revision of an indispensable book.”—Peter H. Raven, Missouri Botanical Garden “This second edition of The Jepson Manual is a monumental achievement! Far more than a simple update, the book has gone through a thorough revision, making it a must-have book for California plant enthusiasts—professional and lay alike."—Lucinda McDade, Rancho Santa Ana Botanic Garden “Biogeographers, vegetation ecologists, and practitioners of conservation and restoration will all welcome the second edition of the Jepson Manual. Many improvements in this second edition include major taxonomic name changes, more information on habitat/range/phenology, better keys, and new illustrations. The second edition is more user-friendly, accurate, and scientifically rigorous. And these improvements are exactly the kind of recent, authoritative, and trusted flora needed.”—Michael G. Barbour, University of California, Davis
