Download or read book Diterpenes of Flowering Plants written by Fred Seaman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 643 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 1200 diterpenes have been identified from approximately 550 Compo sitae taxa (Figure 1 [pp. 219-384], Tables 1-3 [pp. 7-218]). The annual output of such reports rose sharply during the past several years, a trend that was also reflected by other major lipophilic constituents of the Compositae: acetylenes (63, 465), sesquiterpene lactones (266, 458), and benzofurans and chromenes (429). Unlike these other natural products, no review of the diterpene chemistry of the Compositae has been published. Given the bulk of data currently on hand, a review of this topic is clearly overdue. Several major goals influenced the preparation of this review. The first was to provide a useful reference to guide terpenoid chemists to the literature of known compounds. The published reports for 1200 structures provide a sizable body of spectroscopic data applicable to the investigation of new compounds. The study of diterpenes has been hampered by the absence of an all-inclusive nomenclature and classification system for the various skeletal types. Conse quently, a second goal was to organize structural data into a classification scheme designed to group compounds by biogenetic homology, and to standardize such features as diterpene nomenclature and numbering. Pursuant to this goal, the published names (Table 1) and numbering systems (Table 2) for all compounds are included.

Download or read book Arizona Flora written by Thomas H. Kearney and published by Univ of California Press. This book was released on 2023-11-10 with total page 1126 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Flowering Plants and Ferns of Arizona written by Thomas Henry Kearney and published by . This book was released on 1942 with total page 1150 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: “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

Download or read book Gentry s Rio Mayo Plants written by Paul S. Martin and published by University of Arizona Press. This book was released on 2021-11-30 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Río Mayo region of northwestern Mexico is a major geographic area whose natural history remains poorly known to outsiders. Lying in a region where desert and tropical, northern and southern, and continental and coastal species converge, it boasts an abundance of flora first documented by Howard Scott Gentry in 1942 in a book now widely regarded as a classic of botanical literature. This new book updates and amends Gentry's Río Mayo Plants. Undertaken with Gentry's support and participation before his death in 1993, it reproduces the original text, which appears here with annotations, and contains information on over 2,800 taxa—more than twice the 1,200 species first described by Gentry. The annotated list of plants includes information on distribution, habitat, appearance, common names, and indigenous uses. A new introduction provides historical background and a review of geography and vegetation. It also describes changes to the land and river wrought by agricultural development, expanded grazing, and lumbering. Throughout the text, the authors have endeavored to provide information on Río Mayo vegetation while emphasizing local knowledge and use of plants, to preserve Gentry's field-oriented focus, and to present botanical information with Gentry's exuberance and style. Río Mayo Plants has long stood as a book that displays a scientist's love of the English language, his fondness for native peoples, and his eye for beauty in nature. This updating of that work fills a gap in the botanical literature of this portion of North America and will be useful not only for botanists but also for biogeographers, taxonomists, land managers, and conservationists.
