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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
In some populations of Viola trinervata the lower three petals are white with a yellow area proximally (V. B. Baird 1942). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
