The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 4 contains accounts of 82 families, mostly rather small, but including the Primulaceae (with Primula as its largest genus) and Ericaceae (with Rhododendron, the largest genus in the Flora).
The flora of China is astonishing in its diversity. With 32,500 species of vascular plants, over fifty per cent of which are endemic, it has more botanical variety than anywhere else in the world and provides unbroken connections to all its landscapes - from tropical to subtropical, temperate and boreal forests. This book tells the story of the plants of China: from the evolution of the flora through time to the survey of the bioclimatic zones, soundly based on chapters with information on climate, physical geography and soils. The history of botany and its study are also examined, with chapters dedicated to forestry, medicinal plants and ornamentals, with the changing flora, aliens, extinction and conservation also discussed. An essential read for years to come, The Plants of China shows that an understanding of the flora of China is crucial to interpreting plant evolution and fossil history elsewhere in the world.
Ranging from miniature epiphytic orchids to towering trees, and from mangrove forests lining coastal waterways to high-elevation cloud forests, Costa Rica's rich and varied flora dazzles visitors and botanists alike. Tropical Plants of Costa Rica, the first popular treatment to include plants from all regions of the country, is an indispensable guide to native and exotic species found in the neotropics.This book is beautifully illustrated with more than 540 full-color photographs taken in the field, each depicting an entire plant or a closer view of flowers, fruits, or seeds. Instructive pen-and-ink drawings of botanical details also accompany many of the accounts. The text clearly explains each plant's identifying characteristics and reveals fascinating facts about its natural history, chemical properties, economic importance, and medicinal and other uses. Sidebar features throughout the book highlight conservation, ethnobotany, and ecology; their topics include unusual applications for plants, distinct attributes of certain plant families, and plants of particular microhabitats. Tropical Plants of Costa Rica is a wonderful resource for naturalists, students, and researchers, as well as both experienced and first-time visitors to Costa Rica and the American tropics.
Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing natural organic matter. The expansion of agriculture to ever new and more fragile lands, particularly in tropical and developing regions, causes environmental degradation with local effects on soil quality, regional effects on landscape integrity and water quality, and global effects on carbon cycles and the atmosphere. This book summarizes current knowledge of the properties and dynamics of soil organic matter in the tropics, its role in determining soil quality, its stability and turnover, and the options for management in the context of tropical landuse systems, for a readership of resource scientists, economists and advanced students. Maintenance of organic matter is critical for preventing land degradation. Case studies and practical applications are therefore an important part of the book, as are the exploration of future directions in research and management.
An extraordinary compendium of information on herbal medicine, Medicinal Plants of the World, Volume 3 comprehensively documents the medicinal value of 16 major plant species widely used around the world in medical formulations. The book's exhaustive summary of available scientific data for the plants provides detailed information on how each plant is used in different countries, describing both traditional therapeutic applications and what is known from its use in clinical trials. A comprehensive bibliography of over 3000 references cites the literature available from a wide range of disciplines. This book offers an unprecedented collection of vital scientific information for pharmacologists, herbal medicine practitioners, drug developers, medicinal chemists, phytochemists, toxicologists, and researchers who want to explore the use of plant materials for medicinal and related purposes.
