Abstract

Two new and one unrecorded hybrids of the genus Asplenium were newly found in Korea. They were proved to be hybrid based on intermediate morphology between putative parents. The first hybrid is $A.{\times}uiryeongse$ C.S. Lee & K. Lee (Aspleniaceae), nom. nov. (vernacular name: geo-mi-sa-cheol-go-sa-ri). This new hydrid is a cross between the Asian walking fern, A. ruprechtii and A. pekinens in Uiryeong-gil, Mt. Bukansan, Seoul, Korea. The other new one occurs in Mt. Seongsan in Yeoncheon-gun, Gyeonggi-do, Korea, $A.{\times}montanus$ C.S. Lee & K. Lee, nom. nov. (vernacular name: san-kko-ri-go-sa-ri) which might have experienced multiple hybridization events between A. ruprechtii ${\times}$ A. trichomanes and A. incisum following the hybrid between A. ruprechtii and A. trichomanes. In addition, one unrecorded hybrid, $A.{\times}kitazawae$ Kurata & Hutoh (vernacular name: geo-mi-dol-dam-go-sa-ri), reported first from Japan, is found in natural habitats in Do-dong, Daegu-si, and is a hybrid, between the Asian walking fern and A. sarelli. These hybrid taxa grow in sympatric regions with both putative parental species. The diagnostic characters for each taxon and evidence for their hybridization have been suggested. Descriptions, illustrations, and photographs of these hybrid taxa in their habitats are provided from Korea.

꼬리고사리속의 두 개의 신교잡종과 한 개의 미기록교잡종이 발견되었다. 이들 종들의 형태적 형질에 있어 부모종들의 중간형태를 보였다. 거미사철고사리($A.{\times}uiryeongse$)는 서울 북한산 우이령길에서 발견되었고 거미고사리와 사철고사리의 교잡에 의해 분화되었다. 다른 교잡종, 산꼬리고사리($A.{\times}montanus$)는 경기도 연천군, 성산에서 발견되었고, 거미고사리와 차꼬리고사리가 교잡에 의해 만들어지고 다시 꼬리고사리와의 중복교잡에 의해 형성되었다. 아울러 미기록 교잡종인 거미돌담고사리($A.{\times}kitazawae$)는 대구 도동에서 발견되었고, 거미고사리와 돌담고사리의 교잡에 의해 형성되었다. 이들 교잡종들은 부모종들과 같은 장소에서 자란다. 각 분류군의 형질을 분석해 교잡종임을 입증해 보였으며, 이들에 대한 기재, 도해 및 자생지의 서식 사진을 수록하였다.
