Discussion

Viola flettii is endemic to the Olympic Mountains of northwestern Washington. C. S. McCreary (2005) noted that although morphologically and ecologically distinct, V. cuneata, V. flettii, and V. ocellata are closely related.

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).
