Synonym(s):

USDA Symbol: viam

USDA Native Status: L48 (N), AK (N), CAN (N)

A slender, climbing plant clinging to other vegetation or structures by slender, coiling tendrils at end of each leaf; loose racemes of 3-10 deep pinkish-purple to reddish-lavender pea flowers on stalks from leaf axils.

With showy flowers unusually large for the genus, this plant resembles many species of Lathyrus but is distinguished by the distribution of the hairs at the tip of the style. In Vicia the hairs usually surround the tip, resembling a shaving brush; in Lathyrus they are generally on the upperside, like a little hairbrush.
