Discussion

In some populations of Viola beckwithii, the three lower petals are white with a yellow area proximally (V. B. Baird 1942). Leaves have been described as palmately biternate or triternate (L. Abrams and R. S. Ferris 1923–1960, vol. 3), ternately decompound into linear segments (C. L. Hitchcock et al. 1955–1969, vol. 3), palmately three-parted then bipinnately parted into ultimate linear or spatulate segments (P. A. Munz 1959), and palmately about three times three-parted into linear or spatulate-linear segments (W. L. Jepson 1951). Some populations in northern California are nearly or completely glabrous, which M. S. Baker recognized as var. glabrata.

Viola beckwithii is reported to hybridize with V. utahensis (G. Davidse 1976). Observed pollinators of V. beckwithii in Utah include Apis mellifera Linnaeus and Anthophora ursina Cresson (Davidse).

When Cottam described Viola bonnevillensis, he suggested that it could be a hybrid between V. beckwithii and V. utahensis, and G. Davidse (1976) concurred. The type specimen of V. bonnevillensis (Cottam 7067, UT) was examined by R. J. Little. Because no similar forms are known to have been collected since 1939, it is presumed that this taxon is a hybrid.

Viola pedatifida was reported historically from, and recently rediscovered in, the Appalachian shale barrens of Virginia (T. Wieboldt, pers. comm.).

Viola pedatifida reportedly hybridizes with V. sororia (= V. ×bernardii Greene).
