Book Description
Research in recent years has increasingly shifted away from purely academic research, and into applied aspects of the discipline, including climate change research, conservation, and sustainable development. It has by now widely been recognized that “traditional” knowledge is always in flux and adapting to a quickly changing environment. Trends of globalization, especially the globalization of plant markets, have greatly influenced how plant resources are managed nowadays. While ethnobotanical studies are now available from many regions of the world, no comprehensive encyclopedic series focusing on the worlds mountain regions is available in the market. Scholars in plant sciences worldwide will be interested in this website and its dynamic content. The field (and thus the market) of ethnobotany and ethnopharmacology has grown considerably in recent years. Student interest is on the rise, attendance at professional conferences has grown steadily, and the number of professionals calling themselves ethnobotanists has increased significantly (the various societies, like the Society for Economic Botany, the International Society of Ethnopharmacology, the Society of Ethnobiology, and the International Society for Ethnobiology currently have thousands of members). Growth has been most robust in BRIC countries. This new MRW on Ethnobotany of the Himalayas takes advantage of the increasing international interest and scholarship in the field of mountain research. It includes the best and latest research on a full range of descriptive, methodological, theoretical, and applied research on the most important plants in the Himalayas. Each contribution is scientifically rigorous and contributes to the overall field of study.

Book Description
Nearly every life form found among North American flowering plants is represented in Arizona. This amazing diversity is partly explained by the fact that the altitudinal range extends from a few feet above sea level to approximately 12,000 feet at the summit of the San Francisco Peaks. The life zone range from Arctic-Alpine on these peaks to Lower Sonoran in the southwest and Subtropical in the extreme south. The main objective of this book is to provide means for identifying the approximately 3438 species of flowering plants, ferns, and fern-allies growing without cultivation in Arizona. Keys for identification of the families, genera, and species are provided. Under each species the authors give the geographical distribution within and outside Arizona, and usually the altitudinal range and time of flowering. They describe economic uses, toxic or other properties, and ornamental value of many plants, giving particular attention to the utilization of native plants by the large Indian population of the state. Introductory chapters describe the topography, geology, soils, and climate of Arizona, the several types of vegetation in relation to the physical conditions, and the proportional representation of the larger plant families. There is also a brief account of botanical explorations in Arizona since 1832. This is the only available work on the flora of Arizona that includes the results of intensive, botanical research in the state during the past twenty years. It is based on an earlier publication, Flowering Plants and Ferns of Arizona, issued by the U.S. Department of Agriculture in 1942 and now out of print. For the present revision, a supplementary section of more than fifty pages has been prepared under the direction of John Thomas Howell and Elizabeth McClintock of the California Academy of Sciences. This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1960.

Book Description
From the Pinacate lava fields and expansive dunes to the shores of the Gulf of California, the Gran Desierto is one of the hottest and driest places in the Western Hemisphere. Yet this region in the state of Sonora in northwestern Mexico embraces a remarkable number of habitats with a fascinating and surprisingly rich flora. This is the heart of the Sonoran Desert, still in a largely primordial state, in juxtaposition with the ravished wetlands of the once great Río Colorado. Flora of the Gran Desierto is the culmination of more than twenty-five years of research in this magnificent desert and delta by botanist Richard Felger. This comprehensive floristic study of more than 565 species of vascular plants features original diagnostic descriptions and innovative identification keys to the families, genera, and species. Particular attention has been devoted to taxa that are poorly known. Even weeds and their histories are treated in detail. Hundreds of illustrations by such eminent botanical artists as Lucretia Brezeale Hamilton, Matt Johnson, and Bobbi Angell will aid in the identification of plants. Common names of plants are given in English, Spanish, and O'odham. 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 provides botanists, naturalists, ecologists, conservationists, and anyone else celebrating the desert with readable, interesting, and important information. With two of Mexico's newest biosphere reserves—the Pinacate and the Upper Gulf of California—this region is a keystone for desert conservation efforts. Its location linking vast preserves to the north makes this book especially useful for anyone interested in borderland studies and the Sonoran Desert. Flora of the Gran Desierto represents a most creative, definitive, and enthusiastic treatment of Sonoran Desert plant life and is highly relevant to ecological restoration in deserts and wetlands in arid places worldwide.

Book Description
Arizona ranks very high among the States in the richness and diversity of its flora. Approximately 3,200 species of flowering plants and ferns, growing without cultivation, are known to occur within its limits. Many other species have been collected so near the borders of Arizona that they are almost certain to be found in the State. It therefore seems appropriate that the United States Department of Agriculture should undertake publication of a flora of Arizona.
