Viola striata
Dead, long-persistent stems of Viola striata are often present the following season. In flower, the plants are often mistaken for V. canadensis because the petals are whitish (H. E. Ballard 1992).
Viola striata reportedly hybridizes with V. labradorica (= V. ×eclipes H. E. Ballard), V. rostrata (= V. ×brauniae Grover ex Cooperrider), V. walteri var. appalachiensis (= V. ×wujekii H. E. Ballard), and V. walteri var. walteri (= V. ×cooperrideri H. E. Ballard).
