Herbs, perennial, 20-30 cm tall, glabrous; stems and petioles of radical leaves attenuate to filiform underground base. Storage roots numerous, densely fascicled, spindle-shaped, 15-20 × 2-3 mm, sessile or indistinctly stalked. Stems slender, simple, with (1 or)2(or 3) leaves in upper 1/3. Radical leaves long stalked, bi-(tri-)ternate with long slender petiolules; ultimate lobes oblanceolate to linear, 10-15 × 1-3 mm, obtuse. Cauline leaves sessile or petiole to 1.5 cm; blade glaucous abaxially, green adaxially, ovate in outline, with 2 pairs of shortly stalked primary pinnae ternately to binately deeply cut into linear to oblanceolate obtuse to acute lobes 10-25 × 1-3 mm. Raceme 4-10 cm, 8-20(-25)-flowered; lower bracts broadly ovate-acute to narrowly lanceolate, 10-15 × 1-6 mm, usually with a short petiole; upper bracts smaller, ca. 5 mm. Pedicel 10-15(-20) mm, arcuate in fruit. Sepals ca. 0.2 × 1 mm, deeply dentate. Corolla yellow (or greenish?); outer petals with broad (1-2.5 mm) obtuse crest overtopping apex; upper petal 14-16 mm, broad at base, subacute; spur straight (rarely slightly downcurved), cylindric, 5-6 mm, broad; nectary 1/3-2/5 as long as spur, very thin; lower petal 8-11 mm, distal 1/2 reflexed, central part contracted, lower part broadly saccate; inner petals 8-9 mm, claw narrow at base, but broad toward junction with limb. Ovules 14-18, in 2 rows; style 3.5-4 mm; stigma square, median 2 apical papillae narrow, lateral marginal papillae broad, indistinct; geminate papillae lateral and on well-developed basal lobes.
