Abstract

Two naturalized species, Chaerophyllum tainturieri Hook. (Umbelliferae) and Barbarea verna (Mill.) Asch. (Cruciferae) were newly reported from South Korea. C. tainturieri., 'Jeon-Ho-A-Jae-Bi', was found at World Cup park in Sangam-dong, Mapo-gu, in Seoul, and the genus Chaerophyllum is reported for the first time from South Korea in the present paper. It is distinguished from the genus Sphallerocarpus by having cylindrical fruit, and each furrow with one vitta. B. verna, 'Bom-Na-Do-Naeng-I', was found on a riverside area of Suyeong River, Geumsa-dong, in Busan. It can be distinguished from B. orthoceras by silique 4-8 mm long , seeds 1-2 mm long, and basal rosette leaves with a 4-11 large pairs of lateral lobes.

한반도 미기록식물인 Chaerophyllum tainturieri Hook. (산형과)와 Barbarea verna (Mill.) Asch. (십자화과) 2종을 서울과 부산에서 각각 발견하였다. 전호아재비로 이름붙인 C. tainturieri는 서울 상암동의 월드컵공원에서 확인되었다. Chaerophyllum속은 국내에서는 처음으로 본 연구에서 보고되는 미기록속이다. 형태적 유사종인 무산상자속(Sphallerocarpus Besser ex DC.) 식물과 비교하여 열매가 통모양이고, 분과의 갈라지는 틈에 1개의 유관이 있다는 특징으로 구별된다. 봄나도냉이로 이름붙인 Barbarea verna는 부산 금사동의 수영강 둔치에서 확인되었으며, 동속 식물인 나도냉이(B. orthoceras)와는 근생엽의 길이가 4-8 cm이고, 근생엽이 4-11쌍으로 갈라지며, 종자의 길이는 1-2 mm라는 특징으로 구별된다.
