Discussion | Viola selkirkii occurs on the southwestern coast of Greenland, north to 63ºN (L. Brouillet, pers. comm.). Presence of V. selkirkii in the Northwest Territories and Nunavut is considered doubtful (L. Brouillet et al., http://canadensys.net/vascan). K. W. Allred (2008) said that V. selkirkii was considered by W. C. Martin and C. R. Hutchins (1980) to be expected in New Mexico.

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.) |
