Discussion

Much of the foliage of Viola villosa remains green throughout the winter (V. B. Baird 1942).

Viola hallii was discovered on the grounds of Willamette University in Salem, Oregon, by Elihu Hall, a professor at that institution (V. B. Baird 1942). Leaves of V. hallii are similar to V. beckwithii.
