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.

국내산 가막사리속(Bidens L., 국화과)의 분류학적 연구를 수행하던 중, 함경남도 부전고원에서 채집된 두 장의 표본에서 한반도 식물지에 새로운 분류군인 Bidens radiata Thill. var. radiata가 발견되었다. 한국명은 '삼잎구와가막사리'로 신칭하였다. 삼잎구와가막사리는 근연분류군인 구와가막사리 [Bidens radiata Thill. var. pinnatifida (Turcz. ex DC.) Kitam.]와 비교하여 잎이 대부분 3갈래로 갈라지고, 열편은 피침형인 특징으로 구별된다. 이들 B. radiata의 변종들에 대한 검색표가 제시되었다.
