Leaves basal and cauline; basal: 1–5; stipules lanceolate, margins laciniate, apex acute; petiole 1–9.6 cm, glabrous; blade sometimes purple-spotted abaxially and/or adaxially, reniform to ovate, 1–4.5 × 1–4 cm, base broadly cordate to cordate, margins crenate to serrate, mostly eciliate, apex obtuse to acute, surfaces usually pubescent, mostly adaxially toward base, sometimes glabrous; cauline similar to basal except: petiole 0.4–4 cm; distal cauline blades ovate to deltate, 1–4.5 × 1–4 cm, base cordate, apex acuminate to acute. Peduncles 5–9 cm, usually glabrous. Flowers: sepals lanceolate, margins eciliate, auricles 1–2 mm; petals pale lavender-violet on both surfaces, all white basally, lower 3 purple-black-veined, all beardless, lowest 8–20 mm, spur white, purple, or lavender-tinged, elongated, 10–20 mm; style head beardless; cleistogamous flowers axillary.
