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.

V. B. Baird (1942) commented that Viola hastata is more closely related to V. glabella than to any eastern species.
