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.

For years this heterophyllous species was either ignored or included in Viola palmata. C. L. Pollard (1898) and E. Brainerd (1910, 1921) treated it as V. insignis Pollard, a later homonym. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
