Abstract

Here we report a previously unrecorded species of Korean Myriophyllum L. (Haloragaceae). This taxon, M. oguraense Miki has been regarded as a Japanese endemic for some 60 years. Myriophyllum oguraense and its closely related M. verticillatum L. share the characteristic of having pectinate emergent leaves that are similar in shape to, but much smaller than, the submerged leaves. However, the primary characteristic that differentiates these taxa is the turion shape (club shaped in M. verticillatum and linear in M. oguraense). The common name, 'Gin-dong-a-mul-su-sae-mi' was also newly given considering its characteristic turion shape. Photographs and a key to Korean Myriophyllum species are provided in addition to complete descriptions including information on nomenclatural types, distributions and specimens examined.

물수세미속(개미탑과) 1분류군을 국내 미기록종으로 보고한다. 이 분류군은 지금까지 일본에만 분포하는 것으로 알려졌던 Myriophyllum oguraense Miki로서, 근연종인 물수세미(M. verticillatum L.)와 같이 공기중에서 발달된 잎이 빗살모양으로 갈라져 있으나 물 속에 잠겨있는 잎의 크기가 훨씬 작다. 무엇보다 동아가 곤봉 모양으로 발달하는 물수세미에 비해 얇고 가느다란 선모양의 동아를 지님으로서 뚜렷이 구분된다. 새로운 국명 역시 이러한 동아의 특징을 고려해 '긴동아물수세미'로 신칭하였다. 한국산 물수세미속 분류군의 검색키와 더불어 긴동아물수세미에 대한 생육지사진, 형태적 특징, 기준표본 정보, 국내 분포현황 및 관찰표본 목록을 제시하였다.
