Herbs, perennial, 15-30 cm tall, glabrous; stems and petioles of radical leaves attenuate to filiform underground base. Storage roots narrowly oblong, gradually attenuate to short or long stalk, 3-10 cm × 2-3 mm. Stems 2 or 3, 15-30 cm, with 2-4 leaves in upper 1/2, simple or rarely with a branch from upper leaf. Radical leaves few, early withering; petiole 4-15 cm; blade 3-4 × 3-4 cm, biternate to bipinnate, lobes lanceolate to oblanceolate, rarely broadly elliptic, abaxially with distinct raised parallel veins. Cauline leaves: lower leaves with petiole to 1 cm, upper leaves sessile; blade triangular to ovate, ternate to imparipinnate, with 1-3 pairs of deeply ternatisect leaflets, lobes lanceolate; upper leaves triangular, less divided, grading into lower bracts, glabrous to papillose-scabrid on veins abaxially, very finely so along margins, especially on bracts. Racemes dense, elongating, 10-25-flowered; bracts cuneate at base, pectinately divided to coarsely pectinate-dentate, or uppermost lanceolate, entire, equaling or longer than pedicels of 5-10 mm. Sepals whitish, irregular, 0.5-1(-3) × ca. 1 mm, dentate. Corolla pale yellow; keel of outer petals and apex of inner petals orange-yellow; outer petals rhombic, acute, with 1-2 mm wide obtuse crest overtopping apex; spur of upper petal strongly incurved, almost in a semicircle, very rarely almost straight, cylindric, 14-16 mm; nectary 5-6 mm; lower petal with broad, straight to shallowly saccate claw; inner petals 8-10 mm. Ovules 10 or 11; stigma rounded, slightly emarginate; marginal papillae: 2 central narrow and distinct, lateral broad; geminate papillae sublateral and on basal lobes.
