Stems several, from radical leaf axils, simple or few branched, with 1 or 2 leaves. Radical leaves many, 5-15 cm; petiole broadly vaginate; blade oblong, 3-6 × 1.5-2.5 cm, bipinnate; pinnae 2 or 3 pairs, sessile or lower ones shortly stalked; pinnules deeply divided into small crowded imbricate obovate-lanceolate mucronate lobes. Cauline leaves like radical leaves; petiole and leaf midvein broad. Raceme 7-10-flowered, dense at first, at fruiting elongating to 9 cm; lower bract 2-2.5 cm, leaflike or pinnately lobate, upper one 1-1.5 cm. Pedicel 12-15 mm in flower, at fruiting 25-30 mm, arcuately recurved. Sepals early falling, whitish, semicircular, small, fimbriate, incised. Corolla yellow; outer petals narrowly crested, attenuate to both ends; limb elliptic, acute, crest and margins usually crispate-dentate; upper petal 20-22 mm; spur cylindric, 10-12 mm; nectary extended through ca. 1/2 of spur; lower petal ca. 1 cm, shallowly crested; inner petals ca. 8 mm, apex purple-brown, at least adaxially ("internally"); claw shorter than limb. Stigma square, with 4 apical papillae, laterally and on basal lobes with geminate papillae. Capsule nutant, obovoid, 8-12 × 3-4 mm. Seeds in 1 or 2 rows, nearly orbicular, 2-2.5 mm, smooth, ± with beak; caruncle strip-form, ca. 1.5 mm, thick, not appressed, lower 1/2 black, upper 1/2 yellow-brown.
