Rhizome 1-3 cm, with several coarse roots, producing stolons 5-15 cm × ca. 1.5 mm, laxly branched, sparsely set with fleshy scales or petiolar bases, at intervals producing new dense growth with leaf rosette with dense fleshy scales and petiolar bases. Stems 1 or 2 per node, erect, with 2 or 3 leaves in upper 1/2, sometimes with a long-stalked leaf on lower part. Radical leaves since long withered at flowering nodes; petiole 3-7 cm; blade glaucous especially abaxially, 1-4 × 1-5 cm, ternate; leaflets shortly stalked, deeply ternatisect; lobes obovate, shallowly cut into obtuse to acute lobules. Cauline leaves shortly stalked to sessile, 1-5 × 2-6 cm, ternate; leaflets shallowly to deeply once to twice ternatisect into obovate to oblong, obtuse to acute lobes, progressively smaller and less divided upward. Racemes 7-21-flowered, 3-6 cm in flower, elongating to 5-10 cm in fruit; lower bracts like upper leaf, upper narrowly oblanceolate, 4-8 mm, entire. Pedicel erect, 8-20 mm. Sepals minute. Outer petals acuminate, without crest; upper petal 25-27 mm; spur almost straight or slightly downcurved, 13-14 mm, narrowly cylindric, 12-14 mm; lower petal with straight narrow claw and rhombic acuminate dentate limb; inner petals 10-11 mm.
