Radical leaves: blade triangular, 2-4 × 1-3 cm, bi-to tripinnate; secondary leaflets deeply divided into oblanceolate fleshy crowded lobes. Cauline leaves like radical ones, but narrower and shortly stalked.

Pedicel suberect, straight, 15-25 mm, at fruiting hooked at apex. Sepals 0.5-1 × 0.5-1 mm, dentate. Corolla pale blue or white with darker apex, white part with distinct pinkish venation, apex of inner petals tipped with blackish purple, dorsal crests slightly paler; outer petals with triangular subobtuse limb, usually crested; upper petal 14-16 mm, crest not reaching spur, and not overtopping apex; spur slightly downcurved, 3-5(-6) mm; nectary 1/2-2/3 as long as spur, thin; inner petals 9-10 mm. Stigma with broad confluent marginal papillae; submarginal geminate papillae present; basal lobes well developed, with geminate papillae. Capsule obovoid, ca. 6 × 2-3 mm, 5-10-seeded; style 3-3.5 mm.
