Leaves basal; stipules adnate to petioles only at base, free part lanceolate, margin fimbriate or erose; petioles slender, 1-15 cm, glabrous or sparsely puberulous; leaf blade abaxially greenish purple or glaucous, broadly triangular-cordate or cordate to orbicular, 1-4 × 1-4 cm, both surfaces glabrous or sparsely puberulous, sometimes puberulous along teeth, base deeply cordate, margin crenate, apex acute to rounded or obtuse. Flowers violet to white with darker veins, 1.5-2 cm in diam.; pedicels longer, sometimes to 15 cm, glabrous or puberulous, 2-bracteolate above middle; bracteoles subulate. Sepals narrowly lanceolate, 3-5 × 0.5-1.5 mm, apex acuminate, basal auricles shorter, 0.5-1 mm, glabrous. Upper petals subequaling lateral ones, ovate, ca. 1.2 cm, lateral ones glabrous, base cuneate, apex emarginate, anterior one larger, ca. 1.5 cm, apex deeply emarginate or shallowly 2-lobed; spur 5-7 mm, slightly curved. Styles nearly erect; stigmas narrowly margined on lateral sides and abaxially, shortly beaked in front. Capsule globose to ellipsoid, 4-6 mm, glabrous. Seeds ovoid, ca. 1 mm.
