Discussion | 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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 7 (7 in the flora). Varieties of Viola purpurea are variable and intergrade. All are found in California; six occur in other western states, one in Mexico, and one in British Columbia. Mature plants are needed for determination. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
