Carex nakasimae Ohwi (Cyperaceae) is an endemic species on the Korean peninsula. This study reports a new locality of the species, updating the distribution map. A new population of the species was found during field surveys in 2014 in a small swamp in Haman-gun, Gyeongsangnam-do province, located in the southeastern part of the Korean peninsula. In the flowering and fruiting periods of the species, the population is associated with ca. 91 vascular plant taxa from 40 families. To conserve the endemic species, maintaining the habitat is critical. Furthermore, taxonomic and phylogenetic positions of the species should be clarified to establish biological conservation strategies for the rare, endemic C. nakasimae.

The district of Ganghwa-gun in the western coast (Seohae) of the Korea is consisted of several islands, Ganghwa-do, Seokmo-do, Gyodong-do, Jumun-do, Boreum-do, Seogeom-do and Donggeom-do. Since several islands of them were connected to mainland of Korea by bridges, the islands attract a lot of tourists from Seoul, Incheon and Gyeonggi-do areas. Construction of new roads, pensions, resort areas and restaurants provided economical benefits to local residents while natural vegetation of these islands has deteriorated continuously. Before biodiversity of vascular plants in these regions is damaged seriously by human impacts, it is needed to conserve original vegetation of the islands for restoration and monitoring in the future. Therefore, the primary purpose of the study is to clarify the flora of Donggeom-do, belonging to Ganghwa-gun. From the 15 times of field trips to the island, we have collected a number of vascular plants, 512 taxa in total, including 110 families, 329 genera, 449 species, six subspecies, 52 varieties, four forms and one hybrid. Of 512 taxa investigated, we have identified 12 taxa to be endemic to Korea. Six taxa were endangered or rare species which were designated by the Ministry of Environment and Korea Forest Service, respectively. 25 taxa were recognized as floristic regional indicator species designated specially by the Ministry of Environment. Seven species have shown their northern or southern distributional limit ranges, and 29 taxa were recognized as halophytes. The naturalized plants were identified as 55 taxa, and their naturalization ratio was 10.7%.

The vascular plant species in the areas of Gonamsan and Shiribong in the Baekdudaegan were summarized as 295 texa: 89 families, 193 genus, 245 species, 44 varieties and 6 forms.10 taxa were recorded in the surveyed areas as the Korean endemic plants: Hosta capitat (Liliacease), Polygonatum lasianthum var. corenum (Liliaceae), Chloranthus japonicus (Cloranthaceae), Salix hulteni (Salicaoeae), Clematis richotoma (Ranunculaceae), Spiraea prunifolia for. simpliciflora (Rosaceae), Vicia unijuga (Fabaceae), Viola albida (Violaceae), cornus walter(Cornaceae), Weigela subsessilis (Caprifoliaceae).According to the list of Korean rare and endangered plants complied in the studied areas:Iris ensata var. spoyanea(Iridaceae), Viola albida (Vioaceae) and Aristolochia contorta (aristolochiaceae) Due to the rapid destruction and increase of visitors and the studied areas are located close to the villages, the naturalized plant species in the areas were more frequently appeared than the rare and endangered plant species.

A holotype is an element to which the name of a taxon is permanently attached and is key material that facilitates taxonomic research. However, type citation or designation errors due to typographical errors or inadvertent mistakes often exist. When reviewing recently published literature for the type specimens of vascular plants in the herbarium of the National Institute of Biological Resources, we observed that three species, Isoetes laosiensis, Isoetes coreana, and Huperzia jejuensis, had errors, and the actual holotype information and the type descriptions of the protologues did not match. The name Isoetes laosiensis had a collecting number error, while Isoetes coreana and Huperzia jejuensis had collector errors. According to Article 9.2 of the International Code of Nomenclature for algae, fungi, and plants (Shenzhen code), if a holotype designation in the protologue of the name of a taxon is found to contain errors such as collector, collecting number, and illustration errors, the errors are to be corrected. We, therefore, corrected the errors in holotypes of three species, with no alterations made to the intents of the original authors.

Based on the list of rare and endangered plants from the Forest Research Institute and the Ministry of Environment, 22 species were recorded in the studied areas: Thuja koraiensis(Cupressaceae), Arisaema heterophyllum(Araceae), Disporum ovale(Liliaceae), Tricyrtis dialata(Liliaceae), Lilium distichum(Liliaceae), Anemone koraiensis(Ranunculaceae), Rodgersia podophylla(Saxifragaceae), Rosa marretii(Rosaceae), Viola diamantica(Violaceae), Viola albida(Violaceae), Echinopanax horridum(Araliaceae), Acanthopanax chiisannensis(Araliaceae), Lysimachia coreana(Prinmulaceae), Syringa velutina var. kamibayashii, Halenia corniculata(Gentianaceae), Partrinia saniculaefolia(Valerianaceae), Adenophora grandiflora(Campanulaceae), Cacalia pseudo-taimingasa(Compositae) Iris odaesanensis(Iridaceae), Leontice microrhyncha(Berberidaceae), Rpdgersia tabularis(Saxifragaceae), and Acanthopanax sentico년(Araliaceae), Among them the four species were recorded from the list of the Ministry of Environment. As most of the species were recorded from the mountain-trails, the long-term habitat monitoring for the species is required .

This study was carried out to investigate the flora of Mt. Byeollipsan (Ganghwa-gun). The vascular plants from 13 field surveys were revealed to total of 574 taxa; 116 families, 355 genera, 505 species, 8 subspecies, 52 varieties, 7 forms and 2 hybrids.
