Perennial plant. Stemless 2 - 10 (20) cm high. Rhizome branched, at the top with 3 - 10 leaves, flowers and 10 - 20 cm long, 1.5 mm thick, raised, non-rooting aboveground shoots, with consecutive triangular heart-shaped leaves and flowers at the top in the first year. Leaves with petioles, green or dark green, often overwintering and violet below, broadly heart-shaped to triangular- heart-shaped or ovate- heart-shaped, with a deep and narrow cut at the base, finely on the edge, shallow dumb serrated, widest in the lower third , and narrowed upwards with an almost straight, rarely with a convex or concave edge at an acute point, 1.5 - 7.0 (9.0) cm long, 1.5 - 5.0 cm wide, up to 1.5 times longer than wide with 2 - 10 (15) cm long petioles, covered, especially on the petioles, with rough, turned back (up to 1.2 mm long) hairs, rarely almost naked. Stipules linear lance to linear, 1.2 - 2.0 cm long and about 2 mm wide, 6 - 10 times longer than wide, along the edge with lashes longer than half their width, bare or fibrous, pointed. Flower petioles 4 - 6 (8) cm long, naked or with backward bristles, with two bracts above the middle. Flowers 1 - 8, from the top of the rhizome, single in the axils of the rosette leaves or at the top of the shoots, broadly ovate, 1.5 - 2.0 (2.4) cm high and 1.2 - 1.8 cm wide, with an odor. Sepals oblong-ovate or oblong-elliptic, with appendages 4 - 7 mm long, 1.0 - 2.0 (2.5) mm wide, obtuse. Appendages rounded, 1 - (2) mm long. Petals white or purple, rarely red-purple or red; upper back ovate or broadly back ovate, 9 - 11 mm long, 6 - 7 mm wide, curved backwards and sideways; lateral back ovate, 9.0 - 10.5 mm long and 5 - 6 mm wide, at the base with few cilia directed forward and downward; lower petal oblong-ovate, spoon-shaped, incised, with spur 12 - 15 (17) mm long, 5 - 7 (8) mm wide, narrowed at the base into 3 - 4 mm long grooved, ciliate claw inside, passing into the spur; spur directed upwards, 4 - 5 mm long, straight, obtuse, pale purple or whitish, 3 - 4 times longer than the calyx appendages. The ovary is fibrous; the style thickened from the base to the top; the stigma entire, straight or slightly curved beak, equal to or longer than the width of the style. The box is spherical, 8 - 10 mm in diameter, lying on the ground, yellow-brown to brown-violet, white bristly fibrous. Seeds pale yellow, ovoid, 2.0 - 2.5 mm long and about 1.5 mm wide; appendage about 1 mm long.
1 Stolons are sometimes missing. Leaves most often broadly triangular-heart-shaped, 1 - 1.25 times longer than broad, narrowed from the lower third to the apex with a convex, rarely with a straight edge at an acute tip, scattered shortly fibrous. The flowers are purple or white, less often red-violet. Lateral petals with few lashes at the base. The box is short bristly fibrous .......... subsp. dehnhardtii (Ten.) Becker, Veilh. Bayer. Fl.
