Abstract

Unrecorded fern species of Korean flora, Thelypteris interrupta (Willd.) K. Iwats. (Thelypteridaceae) and Dryopteris subexaltata (H. Christ) C. Chr. (Dryopteridaceae), were collected from Jeju island off the south coast of Korean peninsula and reported here. T. interrupta is most similar to T. acuminata (Houtt.) C. V. Morton in morphology, however, the two species are readily distinguishable by the plant color including rhizome, stipe base and spore, and the presence of glandular hair as well as the distribution pattern of sorus on lower leaf surface. D. subexaltata is also well distinguishable from its relatives, D. sparsa (D. Don) Kuntze, D. sabaei (Franch. & Sav.) C. Chr., and D. yakusilvicola Sa. Kurata by the presence of proliferation, shape of pinnae, distribution pattern of sori on lower leaf surface, and shape of indusium.

제주도의 수악계곡과 김녕리에 생육하는 검은별고사리[Thelypteris interrupta (Willd.) K. Iwats.] [처녀고사리과]와 계곡고사리[Dryopteris subexaltata (H. Christ) C. Chr.] [관중과]를 채집하여 국내 미기록종으로 보고하였다. 검은별고사리는 별고사리[T. acuminata (Houtt.) C. V. Morton]와 유사하지만 지하 줄기와 엽병 기부 및 포자의 색깔, 잎 이면의 선모의 유무, 포자낭군의 배열 형태 등에서 차이를 보였다. 계곡고사리는 국내에 분포하지 않는 D. sparsa (D. Don) Kuntze, D. sabaei (Franch. & Sav.) C. Chr., D. yakusilvicola Sa. Kurata와 유사하지만 엽병 기부의 무성아의 유무, 우편의 선단부 모양, 포자낭군의 분포, 포막의 형태에서 차이를 보였다.
