Abstract

A newly recorded species, Fimbristylis hookeriana Boeckeler, was found in Gyema-ri, Hongnongeup, Yeonggwang-gun, Jeollanam-do and Munyeo-do Is., Gunsan-si, Jeollabuk-do, Korea. Fimbristylis hookeriana is closely related to F. dichotoma, which has ovoid spikelets, deciduous scales, pubescent culms, and short style. However, this species is distinguished by very narrowly ovoid spikelets, persistent scales, glabrous culms, and long style. We propose a new Korean name, 'Ba-Wi-Ha-Neul-Ji-Gi', meaning that this inhabits on dried rocks near seashore. Redescription, illustrations, photographs, table, and a key to species of the Fimbristylis Vahl in Korea are provided.

한국 미기록 종인 바위하늘지기(Fimbristylis hookeriana Boeckeler)를 전라남도 영광군과 전라북도 군산시 무녀도에서 발견하였다. 바위하늘지기는 식물체에 털이 없고, 소수가 매우 좁은 난형이며, 암술대가 길고, 인편이 탈락하지 않고 늦가을까지 숙존하는 특징을 가지고 있는데 반하여, 하늘지기는 식물체에 털이 있고 소수가 난형이며 인편이 탈락하는 점에서 구별된다. 이 미기록종의 국명은 주로 바닷가 근처의 건조한 바위위에 자라기 때문에 '바위하늘지기'로 하였고, 바위하늘지기에 대한 기재, 도해, 사진 및 근연종 사이의 차이점을 검색표와 표로 제시하였다.
