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.
