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.

Viola tomentosa occurs in El Dorado, Nevada, Placer, Plumas, and Sierra counties. M. S. Baker (1949) reported that nearly every leaf axil of V. tomentosa produces a flower bud and that these buds produce chasmogamous flowers late in season instead of cleistogamous flowers, as do other members of the V. nuttallii complex. Viola tomentosa hybridizes with V. purpurea; the hybrids appeared sterile (M. S. Baker 1949). J. Clausen (1964) reported a putative hybrid between V. tomentosa and V. sheltonii from one location in Sierra County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
