Plants annual, caulescent, not stoloniferous, 3-25 cm. Stems 1-5, prostrate, decumbent, or erect, branched, glabrous or hairy on stem angles only, clustered on taproot. Leaves cauline; stipules palmately lobed, middle lobe not leaflike, oblanceolate to spatulate, margins entire, ciliate or eciliate, apex acute to obtuse; petiole 0.5-2 cm, glabrous or sparsely pubescent; proximal blades ± orbiculate, distal blades spatulate to broadly oblanceolate, 0.5-3 × 0.3–1 cm, base attenuate, margins entire or crenate-serrate especially toward apex, eciliate, apex rounded to obtuse, surfaces glabrous or sparsely pubescent. Peduncles 1–4.5 cm, glabrous or pubescent. Flowers: sepals ovate to lanceolate, margins ciliate or eciliate, auricles 0.5–2 mm; petals white or cream to pale bluish violet on both surfaces, dark purple-veined, lateral 2 longer than sepals, bearded, lowest 8–10 mm, spur white to blue-violet, gibbous, 1–1.5 mm, shorter than or equaling sepal auricles; style head bearded; cleistogamous flowers axillary. Capsules ellipsoid to oblong, 4–7 mm, glabrous. Seeds beige to bronze, 0.3–1.5 mm. 2n = 34.

Discussion
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).
