초록

한국산 우드풀과 참빗고사리속(Diplazium)내 9 분류군간의 유연관계를 밝히기 위하여 동아시아산 20 분류군을 포함해 군내군 29 분류군과 군외군 개고사리속(Athyrium) 3 분류군 등 총 32 분류군을 대상으로 20개의 형태 형질을 바탕을 maximum parsimony tree와 neighbor-joining tree로 분석하였다. 그 결과 제주도 천지연과 남제주군 교래리에 분포하는 참빗고사리속의 큰잔고사리(Diplazium nipponicum)는 열편의 끝이 뾰족해지고, 땅속줄기에서 엽상체가 인접하는 형질에 의하여 암고사리(Diplazium chinense)와 가장 유사하였다. 큰잔고사리는 비늘조각과 열편의 가장자리가 톱니형이고, 소우편이 겹쳐지지 않는 특징이 암고사리와 달랐다. 큰잔고사리와 암고사리는 우편의 끝이 꼬리처럼 길게 뾰족해지는 형질에 의하여 큰개고사리(D. mesosorum) 및 섬잔고사리(D. hachizoense)와 유사하였다. 이들 군은 일본 특산인 D. subtripinnatum와 일본과 대만에 분포하는 D. kawakamii와 동일군을 형성하였다.

Cladistic analysis was performed to reveal the interspecific relationship of nine taxa of Korean Diplazium (Woodsiaceae). A total of 29 taxa with 20 taxa of eastern asiatic species as ingroup and three taxa of Athyrium as outgroup, were analyzed with 17 morphological characters. Diplazium nipponicum, recently found from Jeju Island, was most closely related to D. chinense by having the acuminate apex of pinnule segment and fascicled fronds. Diplazium nipponicum was distinguished from D. chinense by having scales and pinnule segments of serrated margin, and non-overlapped pinnules. Diplazium nipponicum and D. chinense were closely related to D. mesosorum and D. hajizoense in sequence, by having long acute apex in pinnae. These species formed same clade with D. subtripinnatum, which is endemic to Japan and D. kawakamii, which is distributed in Japan and Taiwan.
