Usually several stems ascending from an oblique, branched rootstock, 3 to 6 inches long at flowering time. Leaf blades orbicular, heart-shaped, crenate-serrate on the margins, blunt, one-half to 2 inches wide, the upper ones smaller and more pointed. Flowers numerous, usually pale violet or rarely white, raised above the leaves on axillary stalks, 2 to 3 inches long.
Common in low ground or moist, shaded woods, Quebec to Minnesota, south to Georgia. Flowering from early spring until late in May.

B. American Dog Violet - Viola conspersa
Closely related, but more dwarfed, with small, orbicular blades and deep violet flowers is the Alpine Dog Violet (Viola 1 abradorica Schrank) occurring in New York only on the higher mountains of the Adirondacks.
The Sand Violet (Violaadunca J. E. Smith; V. subvestita Greene) is finely puberulent, the stems only 2 to 6 inches long; leaf blades ovate, one-half to 1 inch long, crenulate, blunt, subcordate; flowers deep violet, with a straight, blunt spur about 3 lines long. Rather local in sandy or sterile soil or on dry stony ridges, Quebec to Maine and westward.
