Herbs, perennial, 10-50 cm tall, glabrous or sparsely papillose at base of stem and sometimes abaxially on leaf; stems and petioles of radical leaves attenuate to filiform underground base. Storage roots few to several, spindle-shaped, 1-2 cm, narrowed into short or indistinct stalk (more distinct on young tubers). Stems 1-5, usually simple, rarely with 1 or 2 branches, with 2 or 3 leaves in upper 1/2. Radical leaves few; petiole to 14 cm; blade 2-4 × 2-5 cm, pinnate; leaflets cut to base into 2 or 3 linear to oblong lobes. Cauline leaves sessile; blade pinnate; pinnae 2-4 pairs, linear, 2-5 cm × 1-5 mm, entire. Raceme 6-20-flowered, dense, elongating in fruit; bracts lanceolate, entire or lower and middle bracts deeply pectinate-dentate to palmatifid, equaling pedicels. Pedicel 5-10 mm in flower, 10-15 mm and reflexed in fruit. Sepals whitish, 0.3-1 × 0.3-2 mm, finely and sharply dentate. Petals yellow, usually with distinct darker veins, apex usually orange, dorsal crest of inner petals often with small brown mark; upper petal 16-23 mm, subacute to subobtuse, abaxial crest 1-2 mm wide, from apex extended to spur, sometimes not reaching apex; spur straight or slightly downcurved at apex, cylindric, 8-15 mm; nectary ca. 1/2 as long as spur; lower petal obovate, 9-11 mm, abaxial crest smaller than that of upper petal; inner petals 7-9 mm. Stigma square; simple marginal papillae: median 2 distinct, lateral broad and indistinct; geminate papillae lateral (submarginal) and terminating well-developed basal lobes. Capsule narrowly oblong, 10-14 × 1.5-2 mm, smooth or sometimes with thin papillose lines, 3-8-seeded. Seeds 1-ranked, ca. 1.5 mm, smooth, with rather large elaiosomes. Fl. and fr. Jun-Sep.
