A new distribution record of Corydalis edulis (Papaveraceae) in Korea

A new distribution of Corydalis edulis Maxim. is discovered in Korea. This species was collected from the edge of a forest in Hwaseong-si, Gyeonggi-do, Korea. Corydalis edulis is well distinguished from other species of the genus by its annual habit, stigma transversely fusiform, with a papilla at each end and a longitudinal groove on the upper surface. Here, we provide a detailed morphological description, photographs, illustrations, distribution maps of the species, and a taxonomic key to related taxa in Korea. In addition, it is likely that a new habitat will be discovered during plant biodiversity investigations on the Korean Peninsula.
