Discussion | Varieties 3 (2 in the flora). Vicia americana consists of a polymorphic assemblage of populations among which leaflet size, shape, and vestiture is variable. Intergradation is widespread. C. R. Gunn (1968) described two relatively distinct entities which may represent the extremes of a continuum of variation in some regions. Variety sinensis C. R. Gunn occurs in eastern Asia. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Vicia ocalensis is known only from Lake and Marion counties; it is similar to V. acutifolia but differs in its more robust stature and larger leaflets, flowers, and fruits. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
