Given the frequent movement of commercial plants outside their native location, the consistent and standard use of plant names for proper identification and communication has become increasingly important. This second edition of World Economic Plants: A Standard Reference is a key tool in the maintenance of standards for the basic science underlyin

This book offers an up-to-date account of important crops grown worldwide. It provides detailed discussion on the history of plant exploration, migration, domestication and distribution, and crop improvement. The text starts with the origin and diversification of cultivated plants, followed by discussion on tropical, subtropical and temperate crops that are sources of food, beverages, spices and medicines, as well as plant insecticides, timber plants and essential oil-yielding plants. The genetic and evolutionary aspects of different plants and their health benefits are highlighted. The book covers topics dealing with biodiversity conservation, petro-crops, ethnobotanical studies, and important sub-tropical and temperate plants that have commercial importance. The significance of major plant species under each category is described in detail. Illustrated with numerous well-labelled line diagrams and pictures, this book will be useful for students of botany, food and nutrition, forestry, agriculture, horticulture, plant breeding and environmental science.

In 1971, Dr. Quentin Jones, now of the National Hawaii, where an international panel convened to Program Staff, SEA, USDA, suggested that the discuss and assemble information on underexploit Plant Taxonomy Laboratory devise a format for ed tropical legumes. Conversations at that meeting concise write-ups on 1,000 economic plants (Duke and subsequent correspondence with the partici and Terrell, 1974; Duke et al. , 1975). Dr. C. F. pants also yielded new information on some of the Reed was contracted to search the literature on tropical legumes. Finally in 1978, 100 copies of the writeups these economic plants, which included 146 species of legumes. From 1971 through 1974, Dr. Reed were delivered to the International Legume Con prepared rough drafts of write-ups on the 1,000 ference at Kew, July 24th-August 4, and all were species. It was my responsibility to establish the given to potential cooperators before my lecture on format and monitor the write-ups, to ensure that the manual (July 31st). New information presented they would answer many questions on legumes in lectures at that conference and personal com directed to the USDA by our taxpaying public. munications behind the scenes have also been used Since then, a computerized system alerts me to to update and embellish the write-ups so that they new publications on legumes. I have ordered for are more than a bibliographic echo. our files copies of the more promising documents.

This one-semester text is designed for an upper level botany course. Plants in our World emphasizes how people use plants; including fundamental information on morphology, anatomy, and taxonomy as a foundation of general botany. Now in full color, the fourth edition includes molecular data that has immensely altered the understanding of relationships among flowering plants and recently pinpointed the origin of numerous crops. Taxonomy of species has been updated to discuss the system of the Angiosperm Phylogeny Group.

The many spice and aromatic plants are arranged in alphabetical order of their botanical relevance. It includes all species which have been cultivated for the above purposes. It also covers species whose usage has long ceased or which are used only rarely or have become wild. In total over 1400 plants have been collated. The register of literature has been designed to facilitate the study of a specific plant or spice. Works both on botany and agriculture, and on chemistry, pharmacodynamics and usage have been considered.

Major tree crops contribute substantially to the economy of many developing countries on the Asian, African and Latin American continents. For example, coffee is the main revenue earner for Kenya. This book provides a comprehensive review of the agronomy, botany, taxonomy, genetics, chemistry, economics, and future global prospects of a range of crops that have great food, industrial and economic value such as cocoa, coffee, cashew, oil palm and natural rubber. - Discusses the major tree crops of great economic value to the developing world - The author is an eminent scientist who has won numerous awards for his work in this area

Written for the introductory-level course in Economic Botany, this edition offers more emphasis on key topics like biotechnology and ethnobotany.

Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.
