Sceptridium atrovirens and S. microphyllum (Ophioglossaceae): First report in Korea and its phylogenetic position based on morphology
Chang Shook Lee, Yoo Sung Kim
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.
