Discussion | Much of the foliage of Viola villosa remains green throughout the winter (V. B. Baird 1942). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
