Abstract

Two naturalized plants (Euphorbiaceae) were recorded from Busan Metropolitan City and from the Jeju Special Self-Governing Province. Euphorbia heterophylla L. (A-me-ri-ka-dae-geuk) was found in a park near Suyeong-gang, Allak-dong, Dongnae-gu, in Busan Metropolitan City. This species is distinguished from E. dentata by its alternating leaves of main stem and glands of involucres with a circular opening. Euphorbia hirta L. (Teol-ttang-bin-dae) was found in Yerae village, Yerae-dong, Seogwipo-si, in Jeju Special Self-Governing Province. It is distinguished from E. hypericifolia as it has capsules with hairs.

부산광역시와 제주도에서 대극과의 미기록 귀화식물 2종을 발견하였다. Euphorbia heterophylla L. (아메리카대극)은 부산광역시 동래구 안락동 수영강변 공원에서 확인되었으며, E. dentata Michx. (톱니대극)과 비교하여 원줄기 잎은 호생하며, 소총포의 선체 입구는 원형인 특징으로 구별된다. 또한 Euphorbia hirta L. (털땅빈대)은 제주특별자치도 서귀포시 예래동 예래마을에서 확인되었으며, E. hypericifolia L. (큰땅빈대)와 비교하여 삭과에 털이 있는 특징으로 구별된다.
