Viola pedatifida
Viola pedunculata
Viola pedatifida was reported historically from, and recently rediscovered in, the Appalachian shale barrens of Virginia (T. Wieboldt, pers. comm.).
Viola pedatifida reportedly hybridizes with V. sororia (= V. ×bernardii Greene).

The stems of Viola pedunculata arise from an enlarged, subterranean, spongy or fibrous rhizome. Often, these rhizome structures are deep seated; it is unknown how they get so deeply buried. The anther appendages of V. pedunculata are hairy distally, a characteristic not known to occur in other members of the V. purpurea complex.
Larvae of the federally listed Callippe silverspot butterfly [Speyeria callippe (Boisduval) callippe] feed only on Viola pedunculata.
Plants with leaves reported to be smaller, thinner, deltate, mostly longer than wide, with yellow petals (versus orange for Viola pedunculata var. pedunculata), style 2.1 mm (versus 2.9 mm for var. pedunculata), from the Pinnacles region in San Benito County, California, have been called subsp. tenuifolia.
