Discussion | 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.
