Abstract

Herein is described a new species of Rorippa (R. apetala, Brassicaceae) discovered on the River Seom-gang in Wonju-si, Gangwon-do, Korea. The new species is distinct from the closely-related species, R. palustris and R. globosa, by having adventitious buds on the surface of rhizome-type roots during the fruiting season, usually absent or rarely 1-4, if present then atrophy petals, obpandurate fruits, and seeds usually empty or rarely 1-2 per locule. The key to these species is provided.

개갓냉이속(배추과)의 신종인 섬강개갓냉이가 한국의 강원도 원주시 섬강에서 발견되어 기재하였다. 신종은 결실기 때 근경에 생기는 부정아, 일반적으로 무판화이거나 드물게 1-4개의 축소된 화판, 도제금형의 열매, 종자가 대부분 결실하지 않거나 드물게 실당 1-2개를 가짐으로써, 근연종인 속속이풀(R. palustris) 및 구슬갓냉이(R. globosa)와 뚜렷하게 구별되었다. 본 연구에서 이 종들의 검색표를 제시하였다.
