American vetch (Vicia americana)

Abstract

American vetch grows throughout North America. In the United States, it grows in all but the southeastern states, and it is widely distributed west of the Mississippi River (Hickman 1993; Allen and Tilley 2014). It is widespread in the Intermountain Region but becomes less common toward the arid southwestern edge (Barneby 1989). Variety americana occupies the range described for the species (Allen and Tilley 2014; Hitchcock and Cronquist 2018). Variety minor is most common in short-grass prairies and dry woodlands east of the Rocky Mountains, but also occurs in western Montana and eastern Idaho (Allen and Tilley 2014; Hitchcock and Cronquist 2018).
