The long-awaited English edition of the famous "Mansfeld" gives a full account of all agricultural and horticultural plants, other than ornamentals, grown throughout the world presently or in the past. Over 6000 species are covered, including food crops, forage, oil, fibre, and others. For the genera and species information is given on the synonyms, trivial names, occurance, usage, variability and phylogeny. Summaries are given on some hundreds of additional species which have been grown under experimental conditions or in breeding programs. Reference is also made to crops which hardly differ from their wild forms or grown only locally and regionally. This work is a unique documentation of the wide potential of cultivable plants.
