Provides a full account of all agricultural and horticultural plants, other than ornamentals, grown throughout the world presently or in the past. More than 6040 species are covered, including food crops, forage, oil, fibre, spice, medicinal, industrial and so-called auxiliary plants (shade trees, green manure or covered plants). Summaries are given on some hundreds of additional species which have been grown so far only under experimental conditions or in breeding programs. Reference is made not only to highly domesticated or economically important crops, but also to those hardly differing from their wild forms or grown only locally and regionally.
