scopulorum or Viola canadensis var. scopulorum
is a small white-flowered violet found in shady places. Flowers are less than
1 cm wide, and leaves are 3 to 4 cm long. Stems and leaf bottoms are glabrous
Compare to Viola rydbergii, which
is very similar in appearance and habitat. V. rydbergii is slightly larger
and has hairs along the upper stem and on the veins on the undersides of leaves.
Some taxonomists consider V. scopulorum and V. rydbergii to
be varieties or subspecies of a single species, V. canadensis.
