Synonym(s):

USDA Symbol: VIDA2

USDA Native Status: L48 (N)

"In their vernal stage these plants resemble Viola Brittoniana, but the leaves are less deeply cut. The long-auricled calyx of the cleistogamous flowers shows also the relationship to this species. On the other hand the purple-mottled and puberulent capsules are unmistakable evidence of the relationship to V. affliis. (Reslit: 2852 as V. affinis x brittoniana.).

Hybrid progeny of Viola affinis and V. brittoniana. (Webref: 27).
