Discussion | Varieties 7 (2 in the flora). D. Zohary and U. Plitmann (1979) provided a detailed description of the morphological and genetic variation found within the Vicia sativa complex. Of the seven infraspecific taxa they described, two (vars. angustifolia and sativa) are cultivated as forage crops and widely introduced in the flora area. Variety angustifolia is an aggressive colonizer of cultivated and disturbed habitats. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Vicia leucophaea is found in eastern and southern Arizona and in southwestern New Mexico. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
