Characteristics

Acaulescent, with slender creeping rhizomes, and freely stoloniferous, glabrous or variously hairy; petioles and peduncles usually greenish; lvs evidently crenate, broadly cordate-ovate to reniform, commonly 1–3 cm wide at anthesis, later to 8 cm, rounded to blunt to acutish above, the basal sinus more open than in no. 13 [Viola blanda Willd.]; fls fragrant or inodorous, on erect peduncles equaling or rising above the lvs; pet white, the 3 lower with brown-purple veins near the base, the 2 upper narrowly obovate, only slightly (or not at all) recurved, not twisted, the 2 lateral ones beardless or scantily bearded, straighter and more spreading than in no. 13; cleistogamous fls on prostrate or erect peduncles, with green, ellipsoid or ovoid frs 4–6 mm; seeds brown or nearly black; 2n=24. Springy land, and along cold streams, often in shallow water; Lab. and Nf. to B.C., s. to Del., O., Ind., Io., and in the mts. to S.C., Tenn., n. Ga., and Calif. Apr.–July.
