Abstract

Two newly naturalized species were recorded from Incheon (Youngjong-do) and Ulsan. Among them, Bidens polylepis S.F. Blake (Asteraceae) was widespread and was found in the following locations: Unbuk bridge, Unbuk-dong, Jung-gu in Incheon, and Chuiseosan, Banggi-ri, Samnam-myeon as well as a Saemmul mountain cabin on Jaeaksan, Sangbuk-myeon in Ulju-gun, Ulsan. Bidens polylepis can be distinguished from congeneric species by its larger ray-flowers. The Korean name of Bidens polylepis was newly formulated based on the characteristic of its yellow ray-flowers and on the Korean name of the genus Bidens (Asteraceae). The other species, numerous populations of Saponaria officinalis L. (Caryophyllaceae) were found in two areas in Jeotgae village, Unseo-dong, Jung-gu, Incheon. Saponaria officinalis can be distinguished from congeneric species in the family by two features, shallow calyx teeth and a petal with appendages at the base of the blade.

인천광역시(영종도)와 울산광역시에서 2종류의 미기록 귀화식물을 발견하였다. Bidens polylepis S. F. Blake는 노랑도깨비바늘(신칭)로 인천광역시 운북동 운북교 부근과 울산광역시 삼남면 취서산, 상북면 샘물산장 부근에 많은 개체가 넓은 지역에 분포하고 있는 것을 확인하였다. 동일한 속의 유사분류군들과는 설상화(ray-flower)의 크기가 큰 특징으로 구분되고, 노랑도깨비바늘속이며 설상화가 노란색인 특징에 따라 국명을 신칭 하였다. Saponaria officinalis L.는 비누풀로 인천광역시 운서동 젓개마을의 두 장소에서 귀화된 것을 확인하였다. 비누풀의 암술대는 2개, 꽃받침은 깊게 갈라지지 않으며, 잎 기부에는 부속체가 있는 특징으로 석죽과의 다른 분류군들과 구분된다.
