Two newly recorded alien plants Geranium dissectum L. (Geraniaceae) and Dianthus armeria L. (Caryophyllaceae) have been found in Seogwipo-si, Jeju-do and in Hapcheon-gun, Gyeongsangnam-do, of South Korea, respectively. Geranium dissectum can be easily distinguished from other related Korean taxa by fruit with glandular hairs and distinctly reticulated seeds. Dianthus armeria can also be distinguished from other related Korean taxa by its cyme and pubescent calyx. We provide descriptions of the morphological characters, illustrations, photographs and a key to allied taxa.
