Discussion

Variety bellidifolia is found in the Rocky Mountains. Although forms transitional with var. adunca occur, the diminutive var. bellidifolia is quite distinct. V. B. Baird (1942) reported that Viola bellidifolia occurs in the Siskiyou Mountains of California; we have seen no supporting specimens.
