Discussion | Varieties 2 (2 in the flora). V. B. Baird (1942) noted that Viola lobata was more closely related to V. tripartita than to any western Viola. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
N. H. Russell (1965) was the first to consider Viola egglestonii similar to V. septemloba. After analyzing leaf-blade lobing patterns, L. E. McKinney considered it a subspecies of V. septemloba. Although similarities exist between these taxa, we maintain them as distinct species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
