Viola selkirkii
Viola prionantha
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.

In 1952, plants of Viola initially identified as V. patrinii were collected and reported by C. T. Rogerson to be established in lawns on the campus of Kansas State University, Manhattan, Kansas, where they are still found. S. B. Rolfsmeier recently determined that these plants are V. prionantha. R. B. Kaul reported that V. prionantha occurs along roadsides in Kansas and is also established in the floodplain of the North Platte River in Nebraska, where it was first collected by him in 1992.
