This is widespread on mesic or riparian fertile soils in east-central states, including Ky., but it is curioualy uncommon to absent on lowlands of the lower Ohio Rv. and central Mississippi Rv. (K). Hybrids with other species of section Viola in this area are rarely reported from Ky., but H. Ballard (in prep.) stated: "those involving V. labradorica and rostrata are very common" across the range. Although all these species are diploids (2n = 20), their habitats are generally distinct. Without its distinctive creamy-white flowers (with ciliate calyx and prominant quadrate auricles) or fruits (Ballard et al. 2023; W), striata can be distinguished from close relatives (rostrata, conspersa, walteri, etc.) by its larger average leaf size (3-7 cm long versus 1-4.5 cm on primary shoots), with long-acuminate apices (versus rounded to short-acumiinate), and rounded-crenate teeth (versus remotely crenate-serrate wuth more flattened teeth to subentire); also, stipules are larger, on average (ca. 1-2.5 cm long versus 0.5-1.5 cm), with teeth up to 3-5 mm (versus 0.1-3 mm).
