We report an unrecorded species of Viburnum, V. japonicum (Thunb.) Sprengel, found in Gageo-do Island, a subtropical zone in Jeollanam-do Province. We named a species Foo-reun-ga-mak-sal. It is easily distinguishable from other recorded species of Viburnum by the characteristics such as exposed winter buds and indeciduous leaves with lustrous and glabrous texture.

Two marine isopods, Elaphognathia sugashimaensis (Nunomura, 1981) and Metacirolana shijikiensis Nunomura, 2008, have been reported for the first time in South Korea. Specimens of E. sugashimaensis and M. shijikiensis were collected using light traps from Yeongdeok-gun and Gageo-do Island in South Korea, respectively. The genera Elaphognathia Monod, 1926 and Metacirolana Kussakin, 1979 are new to South Korea. In this paper, we provide descriptions of diagnostic characteristics and illustrations of their morphologies. Additionally, the partial sequences of mitochondrial cytochrome c oxidase subunit 1 (CO1) of two species are provided as molecular characteristics.

Three unrecorded species, Carex chungii Z. P. Wang, C. tsushimensis (Ohwi) Ohwi, C. multifolia Ohwi were found in Korea. C. chungii Z. P. Wang was found in Is. Wan and Is. Geogeum, Jeollanam-do and Namhae, Gyeongsangnam-do. This species is distinguished from C. leuchoclora Bunge by achenes constricted above in the middle. C. tsushimensis (Ohwi) Ohwi was found in Is. Gageo, Sinan, Jeollanam-do. This species is distinguished from C. conica Boott by pistillate scales with a long arista. C. multifolia Ohwi was found in Haenam, Jeollanam-do. This species is distinguished from C. sachalinensis var. sikokiana (Franch. & Sav.) Ohwi by caespitose and leaf of light gray. We provide here their description, illustration, photographs and the key of related species.

Five unrecorded species (Oedipodium griffithianum, Myurella tenerrima, Trachypus bicolor, Coscinodon humilis, Meteorium miquelianum subsp. atrovariegatum) with one unrecorded family and two unrecorded genera, were reported as new to the Korean moss flora. The monotypic family Oedipodiaceae consisting of a single genus and single species was distinguished from Splachnaceae by small plants that were 10 mm in length simple or sometimes branched, obovate-spathulate to ${\pm}$ orbicular, costa ending below the apex and entire margins except for the lower long-ciliate portion The species was first found at the top of the Mt. Seorak at an altitude of 1708 m. The two genera, Myurella and Coscinodon were found in the Korean Peninsula. Myurella tenerrima (Theliaceae) was found around the top of Jung-bong on Mt. Jiri. It was mixed with other mosses in the crevices of rocks in the alpine regions. The species is similar to M. sibirica, yet it can be distinguished by the position of papilla in the median laminal cells. Coscinodon humilis (Grimmiaceae) were found on the ridge of Mt. Gaya. C. humilis has a variety of hyaline apex according to leaf position and forms a capsule so it can be distinguished by family. Trachypus bicolor and Meteorium miquelianum subsp. atrovariegatum are unrecorded species. T. bicolor (Trachypodaceae) were found on the ridge of Mt. Gaya. T. bicolor is similar to T. humilis but distinguished by the costal lengths of the leaves. M. miquelianum subsp. atrovariegatum (Meteoriaceae) was found in Gageo-do. This species was distinguished by the plant form and morphology of stem leaves in the same genus.

Asplenium yoshinagae (Aspleniaceae), previously known only from Japan, southwest China to Himalaya, was found in Gageo-do, Heuksan-myeon, Sinan-gun, Jeollanam-do. This species is similar to A. trichomonas, A. tripteropus, A. boreale, A. normale and A. oligophlebium by having gemmae and auricle of pinna, and distinguished from the latters by distinct stipe length, stalk of pinna, acute apex of pinna, length of indusium and shape of sorus. The Local name, Ga-geo-kko-ri-go-sa-ri, was newly given considering the locality. To reveal the interspecific relationships within the genus Asplenium in Korea, cladistic analysis was performed for 22 taxa of Asplenium as ingroup and 2 taxa of Diplazium as outgroup from Korea based on 20 morphological characters. As the results, the genus Asplenium seperated strongly from outgroup, and divided into 4 clades. Asplenium yoshinagae belong to the third clade. A. hondoense N. Murtakami & S. I. Hatanaka, which contained in the second clade, had treated as Hymenasplenium, but this results supported that this taxon may be contained in Asplenium, and also, Asplenium ruprechtii, not in Comptosorus. The morphological characters and illustrations of the species are provided together with photographs of habitat.
