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.

Of conservation concern. Viola frank-smithii is endemic to Logan Canyon, Cache County, Utah. N. H. Holmgren (2005d) wrote that it likely has its ancestral ties with V. adunca. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
