Discussion | 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.

Viola selkirkii occurs on the southwestern coast of Greenland, north to 63ºN (L. Brouillet, pers. comm.). Presence of V. selkirkii in the Northwest Territories and Nunavut is considered doubtful (L. Brouillet et al., http://canadensys.net/vascan). K. W. Allred (2008) said that V. selkirkii was considered by W. C. Martin and C. R. Hutchins (1980) to be expected in New Mexico.
