Herbs, perennial, 5-10 cm above soil surface; stems and petioles of radical leaves attenuate to filiform underground base. Storage roots few, fascicled, 12-30 × 2-4 mm, tapering distally. Bulb (resting bud) broadly ovoid, 5-8 × 5-10 mm, of several pale fleshy scales. Stems erect, thin, simple, with 1 leaf in upper 1/3, or leaf lacking. Radical leaves few; petiole 2-6 cm, thin; blade 6-15 × 8-15 mm, bi-(tri-)ternate, primary leaflets petiolulate, ultimate leaflets sessile, deeply divided into obovate to elliptic lobes. Cauline leaf sessile; blade 0.8-2.5 cm, deeply bi-to triternatisect into narrowly linear lobes 0.5-1(-1.5) mm wide. Raceme umbellate, 1-3 cm, 2-6-flowered, not elongating in fruit; bracts 8-13 mm, deeply cut into 3-13 linear lobes. Pedicel 8-25 mm, thin, erect in fruit. Sepals minute. Petals clear blue, inner petals pale but darker at tip; upper petal narrowly navicular, 13-19 mm, subacute, crest narrow or absent; spur straight or downcurved apically, cylindric, 6-11 mm; nectary ca. 2/3 as long as spur; lower petal 10-13 mm, claw distinct, 4-5 mm, limb orbicular, much surpassing upper petal, 7-10 mm wide, apex truncate; inner petals 7-9 mm.
