Characteristics

Herbs, perennial, glaucous, 10-20 cm tall, glabrous; stems and petioles of radical leaves attenuate to filiform underground base. Storage roots several, 1.5-5 cm × 3-4 mm, gradually narrowed into equally long often branched stalk. Stems 2-6, with 2-4 leaves, nearly always with late branches. Radical leaves few, with very long thin petiole; blade ternate to biternate, 2-4 cm; leaf lobes linear to lanceolate. Cauline leaves sessile, 2-4 × 2-4 cm, like radical leaves. Racemes 1-2 cm, 2-7-flowered, dense, elongating in fruit; lower bracts deeply divided into linear acute lobes, 8-12 mm, uppermost often entire. Pedicel 4-10 mm, recurved in fruit. Sepals ca. 0.5 × 1 mm, dentate. Corolla dull yellow, masked with grayish ochre; upper petal 10-14 mm, subacute; crest narrow, attenuate to both ends, not reaching apex; spur slightly downcurved, 5-7 mm, attenuate; nectary ca. 1/2 as long as spur; lower petal navicular-oblanceolate, ca. 7 mm, margin dentate, crest usually lacking; inner petals 6-7 mm. Stigma square; 2 marginal median papillae distinct, lateral marginal papillae broad and indistinct; geminate papillae sublateral and in basal corners (basal lobes hardly developed). Fruit narrowly obovoid, ca. 1 cm, 6-seeded; style ca. 2.5 mm. Seeds ca. 1.6 mm, smooth. Fl. Jun-Sep.
