Abstract
Two naturalized species, Euphorbia dentata Michx. and Securigera varia (L.) Lassen were newly reported from Korea. Euphorbia dentata, "Top-Ni-Dae-Geuk", was found from Jungbu Highway, Daechang-ri, Daechang-myeon, Yeongcheon-si, Gyeongsangbuk-do. It is distinguished from E. pulcherrima by its life form, which is herbaceous, and its upper leaves, which are uniformly green. Securigera varia, "Wang-Gwan-Gal-Kwi-Na-Mul", was found from Hangang, Yeouido, Seoul. The genus Securigera is unrecorded in Korea and distinguished from genus Hedysarum by rose-colored flowers, a peduncle 5-10 cm and by having dense umbels at the tips of the peduncles.
