Corydalis (from Greek korydalís "crested lark") is a genus of about 540 species of annual and perennial herbaceous plants in the family Papaveraceae, native to the temperate Northern Hemisphere and the high mountains of tropical eastern Africa. They are most diverse in China and the Himalayas, with at least 357 species in China. Corydalis spp. are the only dicots having only a single cotyledon (seed leaf).[1]

Ecology

Corydalis species are used as food plants by the larvae of some Lepidoptera species (butterflies), especially the clouded Apollo.

Toxicity

Corydalis cava and some other tuberous species contain the alkaloid bulbocapnine, which is occasionally used in medicine but scientific evidence is lacking in the correct dosages and side effects.[2]

Many of the species in Corydalis contain other toxins and alkaloids like canadine, which blocks calcium. The species C. caseana is poisonous to livestock.[3]
