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.

Viola bicolor is the only pansy native to North America (V. B. Baird 1942; J. Clausen et al. 1964; A. E. Radford et al. 1968) and is the only annual Viola species that produces cleistogamous flowers (Baird; A. Gershoy 1934). Roots of V. bicolor have the odor of wintergreen when crushed (W. J. Hayden and J. Clough 1990). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
