Corydalis stewartii

Credit: Shaukat

Annual or biennial herb, sometimes perennating with a very short underground rhizome, somewhat weak, branched, sparsely leafy, 10-30 (-50) cm long, glabrous, ± glaucous, sometimes slightly succulent. Leaves ternate, basal and lower long petioled, 10-15 cm long, 3-5 cm broad; pinnae or lobes suborbicular-ovate, cuneate, petiolulate, 5-10 (-15) mm long, and about as broad, 3-lobulate; lobules (ultimate segments) obovate-oblong. 5-10 mm long, cuneate below, ± rounded at apex, obscurely mucronate; petiole about as long as the lamina, much smaller in the upper leaves; petiolule much smaller, filiform. Racemes simple, terminating the branches, many, 5-10-flowered, lax, 3-5 cm long; bracts foliaceous, small, upper gradually becoming entire, linear and much smaller. Flowers pale yellow with darker tips, 6-10 mm long, including slender spur, about half as long; pedicels 2-4 (-5) mm long in fruit, deflexed. Sepals minute, inconspicuous. Upper petal acute to subacuminate at apex, narrow, sometimes with an obscure dorsal wing; lower petal not saccate at base, simple. Capsule linear-oblong, 12-15 mm long, 1.5-2 mm broad, subtorulose, 6-8-seeded, uni- or sub-biseriate, apex subrounded, base somewhat narrowed and seedless; style c. 2 mm long, curved at apex with broad stigma; seeds c. 1.5 mm in diam., black, very minutely tubercled.

Fl.Per. May-Aug.

Type: Kashmir, Sonmarg, 3000 m., 19.7.21, R.R. Stewart 6304 (RAW, K).

Very similar to Corydalis cornuta Royle but fruits narrow linear, rarely slightly oblong, 1.5-2 mm broad, leaf segments not so extended at the apex of leaves. Also resembles Corydalis felicina Prain but larger in size and leaf segments, flowers small with prominent inner petal apex. It seems to have slightly succulent habit and prefers wet habitats.
