Abstract

Two newly recorded alien plants, Lepidium pinnatifidum Ledeb. (Brassicaceae) and Oxalis dillenii Jacq. (Oxalidaceae), were found on Wolmido Island, Incheon-si and in Gyeongseo-dong, Incheon-si, of South Korea, respectively. Lepidium pinnatifidum is distinguished from other related Korean taxa by leaves that are not amplexicaul and four stamens. Oxalis dillenii is distinguished from other related Korean taxa by having bristles which are dense on peduncles and pedicels and by having white ridges on the seed. We provide descriptions of the morphological characters, photographs and a key to allied taxa in Korea.

한국 미기록 외래식물인 털다닥냉이(십자화과)와 들괭이밥(괭이밥과) 2종을 인천시 월미도와 경서동에서 각각 발견하였다. 털다닥냉이는 경생엽이 줄기를 감싸지 않고, 수술이 4개라는 형태적 특징에 의해 근연종들과 구분된다. 들괭이밥은 화경과 소화경에 강모가 밀집하며, 종자에 흰색의 능선이 있다는 형태적 특징으로 근연종들과 구분된다. 본 연구는 미기록 외래식물 2종에 대한 기재와 화상자료를 제공하고, 검색표를 작성하였다.
