Plants perennial, caulescent, not stoloniferous, 5–46 cm. Stems 1–3, erect, leafless proximally, leafy distally, glabrous or puberulent, from subligneous rhizome. Leaves basal and cauline; basal: 0–2, unlobed or palmately 3–11-lobed; stipules ovate to lanceolate, margins ± entire or serrate, apex acute; petiole 5–27 cm, glabrous or puberulent; blade sometimes glaucous, deltate to reniform, 3.5–8.5 × 4.5–13.5 cm, base cordate, truncate, or attenuate, margins on unlobed leaves coarsely dentate-serrate, margins on lobed leaves usually entire, sometimes few-toothed, ciliate (sometimes only proximal 1/2) or eciliate, apex acute to obtuse, mucronulate, surfaces glabrous or puberulent; cauline similar to basal except: distal on naked stems, unlobed and divided leaves can occur on same plant, if divided, palmately 3–12-lobed; stipules sometimes large and ± leaflike, margins entire, lacerate, or laciniate, sometimes with gland-tipped projections, apex acute to acuminate; petiole 0.2–8.8 cm; blade reniform to reniform-cordate, ± ovate, deltate, or rhombic, 1.5–5.5 × 1.4–10 cm, base cordate, subcordate, truncate, or attenuate, margins entire, crenate-serrate, or dentate, or coarsely lacerate to deeply serrate, often entire distally, ciliate or rarely eciliate, apex acute to obtuse, often long-tapered, mucronulate. Peduncles 2–13 cm, glabrous or pubescent. Flowers: sepals lanceolate, margins ciliate or eciliate, auricles 0.1–1 mm; petals deep lemon-yellow adaxially, usually upper 2 and sometimes lateral 2 brownish purple abaxially, lower 3 and sometimes upper 2 brownish purple-veined basally, lateral 2 bearded, lowest 8–19 mm, spur yellow to greenish, gibbous, 0.5–2 mm; style head bearded; cleistogamous flowers axillary. Capsules ellipsoid-ovoid, 6–16 mm, glabrous. Seeds light brown, blotched or streaked with brown, shiny, 2.1–2.7 mm. 2n = 12.
