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.

Flowers of Viola pinetorum have been observed to close up in late afternoon then fully reopen the following morning. Although E. O. Wooton and P. C. Standley (1915) reported Viola pinetorum from New Mexico, the plant was probably V. nuttallii. K. W. Allred (2008) noted that V. pinetorum occurs in California; he did not recognize it in New Mexico. Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
