Viola pedatifida
Viola affinis
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).

L. E. McKinney (1992) considered Viola affinis, and much of what botanists had called V. nephrophylla, to be essentially the same taxon. After studying additional specimens, reviewing literature (H. E. Ballard 1994; A. Haines 2001b), and discussions with others (J. Cayouette, H. E. Ballard, A. Haines, pers. comm.), he chose to maintain these as separate taxa. Reports of V. affinis in the Gulf coastal states based on specimens or photographs are usually attributable to V. missouriensis.
Viola affinis reportedly hybridizes with V. hirsutula (= V. ×consobrina House), V. cucullata (= V. ×consocia House), V. brittoniana (= V. ×davisii House), V. sororia (= V. ×filicetorum Greene [as species]), V. sagittata var. sagittata (= V. ×hollickii House), and V. nephrophylla (= V. ×subaffinis House).
