Viola pinetorum
Viola blanda
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.

Viola blanda occurs in small colonies; individual plants are interconnected by stolons.
Whether to recognize Viola incognita at any taxonomic level is currently unresolved. It is said to have pubescent
leaf blades, greenish peduncles, nontwisted lateral petals, and a preference for moister habitats. Most of these characters fall within the range of variation observed in V. blanda.
N. H. Russell (1965) noted that Viola incognita is principally found in glaciated areas whereas V. blanda is found in nonglaciated areas. Á. Löve and D. Löve (1982b) and J. M. Canne (1987) reported a chromosome count of 2n = 44; J. Clausen (1929) and A. Gershoy (1934) reported 2n = 48. V. B. Baird (1942) reported that V. blanda (and V. incognita) have fragrant flowers.
