  • Two newly recorded species, Cyrtomium laetevirens and Dryopteris simasakii var. paleacea (Dryopteridaceae) were collected from forests in Jeonnam, Geongnam and Jeju-do, with the latter also, found addedly in Gwanaksan, Seoul. C. laetevirens (vernacular name: 'Yun-soe-go-bi) was distinguished from other Korean congeners of the genus Cyrtomium by having glossy laminae, narrow lanceolate, yellow-green pinnae with minutely serrated margin and gradually narrowing shape from base to apex, along with entire, unicolor, and white grayish indusia. D. simasakii var. paleacea (vernacular name: Cheung-cheung-ji-ne-go-sa-ri'), was distinguished by shining leaves, opposite pinnae arrangement, no falcate pinnules, and densely adpressed scaly wholly along with irregular dark brown scales on stipe and rachis. Descriptions and illustrations of the two taxa and their photographs in the habitat are provided along with a key to the species of Cyrtomium and sect. Hirpedes of Dryopteris from Korea.
