Discussion

Viola flettii is endemic to the Olympic Mountains of northwestern Washington. C. S. McCreary (2005) noted that although morphologically and ecologically distinct, V. cuneata, V. flettii, and V. ocellata are closely related.

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.

Viola canina was possibly introduced in Greenland (T. Marcussen and T. Karlsson et al. 2010).

Hybrids of Viola canina are known with the European species V. mirabilis Linnaeus, V. pumila Chaix, V. reichenbachiana Jordan ex Boreau, V. riviniana Reichenbach, V. rupestris F. W. Schmidt (both subspecies), V. stagnina Kitaibel, and V. uliginosa Besser.
