Discussion | Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Viola cuneata often occurs on serpentine-derived soil and is closely related to V. flettii, V. hallii, and V. ocellata (V. B. Baird 1942). Originally described as beardless by Watson, the lateral petals of flowers in the same population can be prominently bearded or essentially beardless. The cauline blades of Viola cuneata are often vertical, especially early in season. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
