Abstract
Corydalis xideensis (Corydalieae, Papaveraceae), a new species from the Xiaoxiangling Mountains, Xide County, southern Sichuan, China, is described and illustrated. C. xideensis is similar to C. schusteriana, but differs from the latter by having 3–12 cm long stolons, bluish green leaves adaxially, pale yellow corolla with yellow apex, outer petals without crest, shorter corolla, shorter spur, larger sepals and very obvious on young flowers, no bulbil in axils of upper cauline leaves.
