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.
