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 'Wang-do-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.

부산광역시 금정구와 경상북도 경산시 진량읍 및 대구광역시 북구에서 채집된 한국산 국화과의 미기록 귀화식물인 Bidens subalternans DC. var. subalternans을 확인하여 보고한다. 본 분류군은 잎은 1회 우상복엽으로 깊게 갈라지며, 소엽은 너비가 좁은 피침형이고, 통상화는 4갈래, 수과는 장타원형으로 한국산 가막사리속 다른 분류군들과 구분이 된다. 국명은 식물체가 대형(특히, 잎 크기)임을 고려하여, '왕도깨비바늘'로 신칭하였다. 한국산 가막사리속 분류군에 대한 검색표를 제시하였다.
