Botanical name: Corydalis cornuta Family: Fumariaceae (Fumitory family)
Horned Corydalis is annual or biennial herb, 15-50 cm tall. Stems are erect or ascending, many branched from base. Stems and branches are ribbed, with many leaves. Leaves all stalked, lower leaves long stalked, upper ones shortly stalked. Leaves are glaucoud below, triangular-oblong, doube- or triple-compound. Leaflets are opposite - ultimate leaflets wedge-shaped-obovate or oblong. Flowers are borne in 10-15-flowered racmes. Bracts are 4-8 mm, divided into acute lobes, or upper ones entire. Flower-stalks are 2-5 mm, rigidly arcuately recurved in fruit. Sepals are about 0.5 mm, toothed. Petals are yellow, sometimes with distinct veins - inner petals tipped with blackish purple, outer petals pointed, abaxially with entire narrow crest. Upper petal is 1.4-1.6 cm, spur straight or slightly downcurved, 6-8 mm, slightly tapering toward the tip. Nectary is extended through about 3/5 of spur. Lower petal is 6-7 mm, broadly sac-like at base. Inner petals are 6-7 mm, claw shorter than limb. Stigma is square with 4 apical papillae, a pair of lateral geminate papillae and basal geminate papillae on distinct basal lobes. Capsule is obovoid, 8-10 × 2-3 mm, 8-16-seeded. Seeds occur in 2 rows, about 1 mm in diameter. Horned Corydalis is found in the Himalayas, from Pakistan to Sikkim, at altitudes of 2300-3600 m. Flowering: July-September.
