Plants perennial, acaulescent, stoloniferous, 5–30 cm; stolons pale, often rooting and leafy at nodes; rhizome slender, fleshy. Leaves basal, 2–6(–9), ascending to erect; stipules linear-lanceolate, margins entire or irregularly lacerate (at least distally), apex acute; petiole 2–12 cm, glabrous or pubescent; blade unlobed, lanceolate or narrowly elliptic to nearly linear, 2.5–12 × 0.7–2.5 cm, longer than wide, base attenuate, margins serrate, mostly eciliate, apex acute, mucronulate, surfaces glabrous. Peduncles 2–17 cm, usually pubescent. Flowers: sepals ovate to lanceolate, margins mostly eciliate, auricles 1–2 mm; petals white on both surfaces, lowest and sometimes lateral 2 purple-veined, lateral 2 sparsely bearded or beardless, lowest 7–12 mm, spur white, gibbous, 1–2 mm; style head beardless; cleistogamous flowers on prostrate to ascending peduncles. Capsules ellipsoid, 5–8 mm, glabrous. Seeds beige to bronze, 1.5–2.5 mm. 2n = 24.
"Acaulescent, glabrous or somewhat hairy, with slender creeping rhizomes, and in summer producing many creeping stolons with cleistogamous fls; lvs narrow, mostly more than 3 times as long as wide, tapering to the base, crenulate to serrate; pet white, the 2 upper linear- oblong or broadly oblong to obovate, the 3 lower with brown-purple veins near the base, all beardless; cleistogamous fls on erect peduncles; frs green, ellipsoid, 5–8 mm; seeds brown; 2n=24. Wet, open places, often along streams and ponds, especially in sandy soil; Me. and N.B. to Fla., w. to w. Ont., Minn., e. Okla., and e. Tex. Apr.–June. Two vars.: Var. lanceolata, with lanceolate lvs mostly 3.5–6 times as long as wide, is chiefly northern, and widespread in our range. Var. vittata (Greene) Weath. & Griscom, with narrower lvs mostly 6–16 times as long as wide, is more southern, occurring chiefly on the coastal plain from Va. to Fla. and Tex., with a disjunct area at the s. end of Lake Michigan.
