Herbs perennial. Rhizome obliquely ascending, short, stout, densely covered with scales, with numerous dark brown roots. Stems to 22 cm tall, slender, glabrous or pubescent, usually simple, leafless in lower part. Basal leaves usually 1 or 2, sometimes absent, long petiolate; leaf blade deep green on both sides, deeply cordate, 5-9 × 3-7 cm at base, glabrous or pubescent, margin large serrate, apex long acuminate. Cauline leaves: lower stipules nearly ovate, 7-9 mm, much shorter than petiole, margin remotely and large toothed, upper ones rhombic-ovate or broadly lanceolate, 1.5-2.5 cm, subequaling or longer than petiole, margin remotely and large toothed or shallowly 3-lobed; petiole 1.5-4 cm; leaf blade slightly glaucous abaxially, usually triangular-ovate or broadly cordate, 3-5 × 3-6 cm, sometimes sparsely puberulous along veins and margin, base truncate or broadly cordate. Flowers in axils of cauline leaves, yellow; pedicels 3-4 cm, slightly shorter than leaves, 2-bracteolate below flower; bracteoles undeveloped, linear. Sepals linear, ca. 4 mm, apex acute, basal auricles short, 3-veined, apex truncate. Upper petals obovate, ca. 1.1 cm, lateral ones spatulate, ca. 1 cm, anterior one broadly obovate, ca. 8 mm, base purple striate; spur short, 0.5-0.9 mm, apex obtuse. Stigmas 2-lobed, lobes spreading, straight, apex obtuse. Capsule ovoid-globose, small.
