|discussion=<p>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.</p><!--
--><p>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.</p>
