| Abstract |

We report a newly naturalized species of the genus Bidens L. (Asteraceae) in Korea, specifically Bidens subalternans DC, var. subalternans. This naturalized plant was discovered Geumjung-gu in Busan; Gyeongsan-si, Jillyang-eup in Gyeongbuk-do; and in Buk-gu in Daegu. Bidens subalternans var. subalternans is distinguishable from other Bidens in Korea by the following combination of characteristics: an odd-pinnate leaf, deeply lobed, narrow lanceolate, four lobes in the corolla, an oblong achene shape. This taxon is termed ``Wangdo-kka-bi-ba-neul`` as a common Korean name based on its large size (in particular, the size of leaf). The key for all taxa of the genus Bidens in Korea is also provided here. |
