Herbs, perennial, 14-30 cm tall, glabrous; stems and petioles of radical leaves attenuate to filiform underground base. Storage roots 3-5 cm × ca. 1 mm, tapering to both ends. Bulb prominent, white, rounded, ca. 0.5 × 0.5 cm, of several fleshy ovate scales, apparently becoming hard. Stems 1 or 2, erect, thin, simple or with 1 branch from upper leaf axil, with 2 leaves near middle. Radical leaves few; petiole 5-12 cm, very thin; blade 1-1.5 × ca. 2 cm, ternate; leaflets shortly petiolulate, deeply 2-4-divided; lobes oblanceolate. Cauline leaves subsessile or rarely lower ones with petiole to 1.5 cm; blade 2-3 cm, deeply biternatisect into narrowly lanceolate to linear lobes. Raceme 2-5 cm, 8-19-flowered, dense at first, elongating in fruit; lower bracts 10-17 mm, deeply 3-7-fid into linear lobes; upper bracts linear-lanceolate, 8-12 mm, entire. Pedicel 13-30 mm, very thin, presumably erect in fruit. Sepals minute. Corolla sky blue, inner petals pale, apparently dark blue at apex; upper petal broadly rhombic, 14-15 mm, subacute to subacuminate, crest ca. 1 mm wide, tapering to both ends, not decurrent on spur; spur straight, cylindric, ca. 7 mm, rather narrow; nectary 1/2-2/3 as long as spur, thin; lower petal ca. 10 mm, acute, with very prominent rounded lateral flaps, broadly crested; inner petals 8-9 mm. Stigma with 4-6 marginal papillae; geminate papillae on basal lobes. Fruit and seed unknown. Fl. Jul-Aug.
