Abstract

Cyrtomium yamamotoi Tagawa is an unrecorded species of perennial Pteridophyta that belongs to the genus Cyrtomium of Dryopteriaceae. It is known as native to Taiwan, China and Japan, but we found it in Jeju-si, Jeju-do and Haenam-gun, Jeollanam-do, Republic of Korea in 2018. This species is very similar to C. fortunei J.Sm. having characters such as 1 pinnate compound leaves, globular indusium, but distinguished from the latter by its lanceolate or lanceolate-ovate shaped lateral pinnates of less than 12 pairs, bicolor indusium with dark brown or blackish in center, and margin incised teeth. Here, we provide its description, photographs and a key of related taxa in Korea.

반들산쇠고비(Cyrtomium yamamotoi Tagawa)는 관중과 쇠고비속(Cyrtomium Presl)에 속하는 미기록 양치식물이다. 지금까지 타이완, 중국, 일본에 자생하는 것으로 알려져 왔으나, 2018년 제주도 제주시와 전라남도 해남군에서도 자생하고 있음이 확인되었다. 본 종은 근연분류군인 쇠고비(C. fortunei J.Sm.)와 1회 우상복엽이고, 구형의 포막을 가지는 특징 등으로 매우 유사하지만, 반들산쇠고비는 피침평 또는 피침상 난형의 우편이 12쌍 이하이고, 포막의 중앙부는 암갈색 또는 흑색을 띠며, 가장자리에 얕은 톱니가 있는 특징으로 구분된다. 본 연구에서는 반들산쇠고비의 상세한 형태학적 기재와 한국산 쇠고비속의 명확한 동정을 위한 주요 형태 형질 사진 및 검색표를 제시하였다.
