Abstract
During the systematic study of the genus Bidens L. (Asteraceae) in Korea, we found two specimens collected from Bujeon Plateau, Hamgyungnam-do, which are recognized as a new taxon (B. radiata Thill. var. radiata) for the flora of Korea. The Korean name for this taxon is newly designated as 'Sam-ip-gu-wa-ga-mak-sa-ri'. The close relative of this taxon is B. radiata Thill. var. pinnatifida (Turcz. ex DC.) Kitam., but B. radiata var. radiata can be distinguished from B. radiata var. pinnatifida by having mostly 3-parted and lanceolate lobe of leaf. The key for varieties of B. radiata is given.
