Acaulescent, glabrous perennial from a thick, fleshy rhizome. Leaves 5-9, deeply 5-9-lobed, homophyllous (early and mid-season leaves similarly lobed); middle lobes of leaf blades lanceolate or spatulate to narrowly obovate. Sepals lanceolate to ovate, auricles 2-3 mm; petals pale to soft reddish violet, lower three white basally, dark violet-veined; lateral petals bearded, lowest petal 1-2.5 cm and sometimes bearded; capsule ellipsoid, 1-1.5 cm, glabrous; seeds beige, mottled to bronze, 1.5-2.5 mm.

Notes

Wetland indicator: FAC

These plants were photographed in southern NJ growing in nearly pure sand. Has in the past been considered a variety or subspecies of V. pedatifida. Viola pectinata Bickn. is a closely related species with sharply toothed leaves that is sometimes considered by some to be merely a form of V. brittoniana.
