A strict, somewhat woody erect perennial, 25-50 cm tall, branched from the base with somewhat angular, striated stem, glabrous, glaucous; rootstock thick, shortly branched above and covered with withered slightly sheathing half bases. Leaves bipinnatisect, usually with 2 opposite pairs of lateral pinnae and a terminal one close to the upper lateral pair, (3-) 5-10 cm long, 1.5-3 cm broad; petiole about half as long as the leaf; pinnae 10-25 mm long, 8-15 mm broad, subsessile, ovate to suborbicular, often with 4 deeply cut lobes, one near the base and 2-3 lobes above; lobes (ultimate segments) oblong-obovate, 3-8 (-10) mm long, 1.5-3 mm broad, obscurely to slightly mucronate, acute or obtuse. Racemes often with 1-2 branches, each 10-20-flowered, congested when young, conspicuously ciliate looking due to tailed long sepals, becoming somewhat lax later on and in fruit, 3-5 (-7) cm long; bracts narrow, linear lanceolate, conspicuously acuminate, subentire to sparsely denticulate, 5-7 mm long, 1.5-2 mm broad. Flowers yellow, 15-18 (-20) mm long, narrow cylindrical with spur about 1/3 as long and often shortly saccate and curved at base, apex subglobosely hooded. Sepals very conspicuous, 8-10 (-12) mm long, 1-1.5 mm broad, linear-lanceolate with tapering tail-like apical part, ovate, subcordate, denticulate-lacerate at base or with cristate margin, subfimbriate. Upper and lower petal semi-globose near apex with apex minutely acuminate or mucronate, margin narrowly winged, somewhat fimbriate-denticulate. Ovary narrowly lanceolate, oblong, with about equally long style with dilated stigma. Capsule (immature) deflexed, narrowly linear-oblong, similar to the young fruits of Corydalis flabellate Edgew.
Fl. Per.: May July.
Type: W. Pakistan. Chitral, S. M. Toppin 359 (K).
It resembles very closely in its flowers and fruits Corydalis flabellate Edgew., and no doubt is an ally of that group, but leaf segments and sepals are different.
