Peduncles 2–9 cm, usually glabrous. Flowers: sepals with or without purple stripe on both sides of midvein, narrowly lanceolate to oblong, margins ciliate or eciliate, auricles 0.5–1 mm; petals deep lemon-yellow on both surfaces, lower 3 and often upper 2 brownish purple-veined, lateral 2 beardless, lowest 6–15 mm, spur yellow to yellowish green, gibbous, 2–2.5 mm; style head beardless; cleistogamous flowers axillary. Capsules oblong-ovoid, 3–6 mm, glabrous or sparsely pubescent. Seeds purple, sometimes streaked with light and dark brown, 1.5–2.5 mm.
Perennial; rhizome horizontal or oblique, more or less stout, roots on lower surface, leaves and stems at apex. Stems up to 8 cm, slender, ascending to erect, with leaves along their length and flowers distally. Leaves ¾-1¼ by 1-2½ cm, 1¼-2times as broad as long, reniform to broadly ovate, more or less deeply cordate, rounded to broadly obtuse, subcrenate to repand-dentate, especially on lobes, subcoriaceous, glabrous beneath, sparsely hirsute towards margins and on veins above, dark green; petiole ½-5 cm, slender. Stipules 2-4 by 2-3 mm, ovate, acute, entire to sparsely denticulate, glabrous, fuscous, free. Flowers 8-12 mm, yellow with brownish-purple veins; peduncle 1.4-8 cm, much exceeding leaves, slender. Sepals 3-4 by c. 1 mm, linear to linear-oblong, acute, glabrous or shortly ciliate on margin, fuscous, with margin scarious; appendage up to ½ mm, rounded, glabrous. Petals 2-3 times as long as broad, obovate to almost oblong, basal exceeding the others, laterals not bearded; spur 1-1½ mm, cylindrical, obtuse.
