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 2 (2 in the flora). V. B. Baird (1942) noted that Viola lobata was more closely related to V. tripartita than to any western Viola. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
