Discussion | Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Nonflowering plants of Viola renifolia and V. epipsila appear similar. The abaxial leaf surfaces of V. renifolia usually have a few short, straight hairs on the main veins; leaves of V. epipsila are usually glabrous (C. Parker, pers. comm.). Viola renifolia can appear similar to V. macloskeyi. V. B. Baird (1942) wrote that V. renifolia sometimes produces ascending stems. H. A. Gleason and A. Cronquist (1991) noted that if stolons were present, they were short and racemelike with cleistogamous flowers. The ascending stems and stolons mentioned by these authors may or may not be different phases of the same structure. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
