  • Two unrecorded species (Sceptridium atrovirens and S. microphyllum), previously known only in Japan, were found in a forest in Dosun-dong, Seogwipo-si, Jeju-do for the first time in Korea. S. atrovirens was distinguished from other related species of the genus Sceptridium in Korea by having the thickest rhizome and root, irregularly crenulate or roughly serrate, and a shorter sporophore blade. The local name was newly given as 'Sup-go-sa-ri-sam' for the species, denoting the habitat. S. microphyllum was distinguished by having the smallest plant height, compact sterile blades, and partly lateritious tropophyll in winter. The local name was newly given as 'Aegi-go-sa-ri-sam' for species, meaning of a small size. To reveal the interspecific relationships within the genus Sceptridium in Korea, cladistic analysis was performed for 27 morphological characteristics. The morphological characteristics and illustrations of the two taxa, as well as photographs at the habitat, are provided with a taxonomic key to the species of Sceptridium in Korea.

  • To understand the status of ferns' distribution of Gwangneung forest, flora survey was done during the period of April 2003 to November 2005. The results obtained from this study were as follows: Ferns identified and surveyed were 46 taxa including 9 families 17 genera 43 species 3 varieties were recorded in Gwangneung Forest. Hemicryrtophyte (H) was the most common dormancy from recorded in surveyed area. Epiphyte (E) and Hydatophyte (HH) were calculated as 4.3%, 2.2%, respectively and they were the lower value compared to those of other dormancy form. Consequently, $H-R_{3}-D_{1}-t$ was recorded as the most common life-form of ferns in Gwangneung Forest. Pteridophyta-Quotient (Ptph.-Q.) was calculated as 1.28 and it was the higher value compared to those of other neighboring mountains.
