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.
