Discussion
Although exhibiting variation in leaf-blade shape, var. sagittata is usually easily distinguished. There have been misconceptions regarding the identity of Viola emarginata, a species thought for a time to be different from V. sagittata. The type specimen of V. emarginata is conspecific with that of V. sagittata; E. L. Greene (1898b), apparently not having seen the type, portrayed V. emarginata with a somewhat deltate leaf form. N. H. Russell and A. C. Risser (1960) suggested that most collections representing V. emarginata were hybrids.
Variety sagittata reportedly hybridizes with V. cucullata (= V. ×porteriana Pollard), V. hirsutula (= V. ×redacta House), V. pedatifida var. brittoniana (= V. ×mulfordiae Pollard), V. sagittata var. ovata (= V. ×abundans House), and V. sororia var. sororia (= V. ×conjugens Greene).
