초록

경북 영천시와 서울 여의도에서 미기록 귀화식물 2종을 발견하였다. 톱니대극으로 이름 붙인 Euphorbia dentata Michx.(대극과)는 경북 영천시 대창면 대창리 중부고속도로에서 확인되었으며, 동속식물인 포인세티아 (E. pulcherrima)와 비교하여 초본이면서 정상엽들이 한결같이 녹색인 특징으로 구별된다. 또한 왕관갈퀴나물로 이름 붙인 Securigera varia (L.) Lassen(콩과)는 서울 여의도 한강둔치에서 확인되었으며, Securigera속은 국내 미기록속이다. 형태적 유사종으로 묏황기속(Hedysarum L.) 식물에 비해 꽃이 담홍색이고 길이 5-10 cm의 꽃자루 끝에 20개 내외의 꽃이 산형으로 붙는 특징으로 구별된다.

Two naturalized species, Euphorbia dentata Michx. and Securigera varia (L.) Lassen were newly reported from Korea. Euphorbia dentata, "Top-Ni-Dae-Geuk", was found from Jungbu Highway, Daechang-ri, Daechang-myeon, Yeongcheon-si, Gyeongsangbuk-do. It is distinguished from E. pulcherrima by its life form, which is herbaceous, and its upper leaves, which are uniformly green. Securigera varia, "Wang-Gwan-Gal-Kwi-Na-Mul", was found from Hangang, Yeouido, Seoul. The genus Securigera is unrecorded in Korea and distinguished from genus Hedysarum by rose-colored flowers, a peduncle 5-10 cm and by having dense umbels at the tips of the peduncles.
