Book Description
Excerpt from Botanical Features of North American Deserts Botanical science in its technical and applied branches has reached a stage of development in which it has become plainly evident that adequate progress in research in physiology, in comprehensions of life histories, and in formulating the general principles governing the origin, environic relations and distributional movements of plants may be expected only by experimental methods in the field or in actual contact with the types of plants under consideration under normal environmental conditions. In no part of the subject is this so imperative as in the study of the xerophytic and highly specialized forms characteristic of the desert regions of the world, which comprise a total area equal to that of a large continent. The aridity, widely ranging temperatures of soil and air, physical and chemical properties of the soils, conditions of insolation and radio-activity, together with the special forces modifying distribution, furnish a set of conditions not easily duplicated by the regulation of the artificial climates of glass-houses and not adequately represented by preserved material in herbaria and other collections. A European botanist of ability scarcely lays down his work at the end of a life of zeal and industry devoted to the study of the cacti under cultivation in a climate entirely foreign to them, when an examination of these peculiar forms in their native habitats reveals the necessity for a complete repetition of the entire investigation. When the Carnegie Institution of Washington was established, Mr. Frederick V. Coville determined to present to it a plan for a Desert Botanical Laboratory. This long-cherishcd project was an outcome of his work in the Death Valley Expedition, in 1891. A plan was accordingly drawn up by him and presented to the Institution's Advisory Committee in Botany. This committee considered and approved it because it promised results concerning the fundamental processes of protoplasm as important as any in the whole realm of botany. The Board of Trustees of the Institution also gave their approval to it, and appropriated $8,000 for the establishment of such a laboratory and its maintenance for one year. Messrs. Coville and MacDougal were appointed by the Institution as an Advisory Board in relation to the matter. This Board decided to place the Laboratory under the immediate charge of a resident investigator, who should carry on researches under its guidance, and should be responsible to it in his relations to the Institution.

Book Description
Did you know that the smell of sassafras blowing offshore convinced Columbus he was near land? Or that the American sycamore, which has the largest tree trunk in the eastern forest, can live for 500 to 600 years? Or that in the period before the American Revolution, patriots designated a sycamore tree in each colony as a "Liberty Tree" -- a meeting place for plotting against the British? These facts are just a few of thousands you'll find inBotanica North America, an encyclopedia of the wonderfully diverse North American native plants by noted Canadian garden writer Marjorie Harris. This charming compendium is filled with more than 420 entries that provide essential information on each plant's physical attributes, natural history, common uses, and ethnobotany. There are also fascinating, often surprising anecdotes about plants you won't find anywhere else. From the Eastern forest to the desert, this beautifully written volume roves across the continent exploring how climate and plant life have affected, aided, and inspired us, from the first Native Americans to North Americans living in the twenty-first century: "The lonely majesty of a wind-swept jack pine has inspired generations of poets and painters," Harris writes. "These trees endure in spite of terrible weather . . . a jack pine forest has a dense, closed canopy with an understory of cherry, blueberry, hazels, bracken, and sweet fern along with trailing arbutus." Comprehensive and engaging, Botanica North America is also filled with lush photographs of plants in their natural habitat and insightful quotes from a variety of gardening experts and amateurs, from naturalist Rachel Carson to famed conservationist John Muir. Here is a reference no gardener or environmentalist should be without.

Book Description
Winner of the Society for Economic Botany’s Mary W. Klinger Book Award The seemingly inhospitable Sonoran Desert has provided sustenance to indigenous peoples for centuries. Although it is to all appearances a land bereft of useful plants, fully one-fifth of the desert's flora are edible. This volume presents information on nearly 540 edible plants used by people of more than fifty traditional cultures of the Sonoran Desert and peripheral areas. Drawing on thirty years of research, Wendy C. Hodgson has synthesized the widely scattered literature and added her own experiences to create an exhaustive catalog of desert plants and their many and varied uses. Food Plants of the Sonoran Desert includes not only plants such as gourds and legumes but also unexpected food sources such as palms, lilies, and cattails, all of which provided nutrition to desert peoples. Each species entry lists recorded names and describes indigenous uses, which often include nonfood therapeutic and commodity applications. The agave, for example, is cited for its use as food and for alcoholic and nonalcoholic beverages, syrup, fiber, cordage, clothing, sandals, nets, blankets, lances, fire hearths, musical instruments, hedgerows, soap, and medicine, and for ceremonial purposes. The agave entry includes information on harvesting, roasting, and consumption—and on distinguishing between edible and inedible varieties. No other source provides such a vast amount of information on traditional plant uses for this region. Accessible to general readers, this book is an invaluable compendium for anyone interested in the desert’s hidden bounty.
