Viola tomentosa
Viola pedunculata
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.

The stems of Viola pedunculata arise from an enlarged, subterranean, spongy or fibrous rhizome. Often, these rhizome structures are deep seated; it is unknown how they get so deeply buried. The anther appendages of V. pedunculata are hairy distally, a characteristic not known to occur in other members of the V. purpurea complex.
Larvae of the federally listed Callippe silverspot butterfly [Speyeria callippe (Boisduval) callippe] feed only on Viola pedunculata.
Plants with leaves reported to be smaller, thinner, deltate, mostly longer than wide, with yellow petals (versus orange for Viola pedunculata var. pedunculata), style 2.1 mm (versus 2.9 mm for var. pedunculata), from the Pinnacles region in San Benito County, California, have been called subsp. tenuifolia.
