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.

Varieties 7 (7 in the flora). Varieties of Viola purpurea are variable and intergrade. All are found in California; six occur in other western states, one in Mexico, and one in British Columbia. Mature plants are needed for determination. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
