  • A morphological study of Korean Fimbristylis was conducted in order to clarify the taxonomical position and scientific names among species. It was determined that the anther size and style length are important characteristics for the species-level identification of Fimbristylis. It was confirmed that Fimbristylis ovata (Burm.f.) J. Kern, which is recorded in the literature but which has no sampling specimens in Korea, grows on the grassland on Marado Island. According to this study, the genus Fimbristylis in Korea is classified into a total of 21 taxa, including four sections, nineteen species, and two varieties.

  • We report Fimbristylis ovata (Burm.f.) J. Kern (Cyperaceae) from the sunny grasslands along the coastline on Jejudo Island, Korea, as a new distribution in Korea. This is thought to be the third confirmed record of this rare sedge in Korea; the first was from Gapari ('Is. Quelpaert') collected by Taquet in 1908, and the second was from Marado Island, collected by Kim and Kim in 2018. We found two new populations on Jejudo Island, the first with many individuals and the second with only a few plants. Following an examination of herbarium specimens, this species is considered to be rare and endangered in Korea, limited in distribution in Korea to Jejudo and Marado Islands.

  • Fimbristylis fimbristyloides (F. Muell.) Druce (Cyperaceae) belonging to Fimbristylis sect. Fuscae Ohwi, which has been ambiguous in terms of its distribution and taxonomic substance in Korea, was found on Amtae-do Island, Sinan-gun, Jeollanam-do in Korea. F. fimbristyloides is a small species that is approximately 5-15 cm tall and differs greatly from most taxa in that the spikelets are laterally compressed. In particular, F. fimbristyloides is similar to F. ovata but is distinguished by the height of the plants, falcated leaves, the number and size of spikelets per inflorescence, glabrous styles, the size of the achenes, and the presence of achene stalks. A description, differences from related species, a key to the taxa and photographs of Korean F. fimbristyloides are provided in this paper.

  • To provide fundamental information to areas that lack data on the plant resources and the ecosystem, this study conducted a survey on the vascular plants in Mt. Jigisan in Hongseonggun. The vascular plants identified during the six-round field surveys were a total of 443 taxa: 96 families, 286 genera, 391 species, 7 subspecies, 40 varieties, 3 forms, and 2 hybrids. On floristic regional of Korea, Mt. Jigisan is deciduous broad-leaved and conifer-mixed forest which is south province of Korean peninsula. 4 taxa of Korean endemic plants such as Populus ${\times}$ tomentiglandulosa, Forsytsythia koreana, Forsytsythia ovate, and Iris rossii var. latifolia were collected. The vascular plants on the red list according to IUCN evaluation basis were found to be 6 taxa: Vulnerable (VU) species of Forsytsythia ovata, Least Conern (LC) species of Chionanthus retusus, Pseudoraphis ukishiba, and Cymbidium goeringii, and Not Evaluate (NE) species of Panax ginseng, and Fimbristylis verrucifera. The floristic regional indicator plants were found 27 taxa: 2 taxa of grade V, 3 taxa of grade IV, 6 taxa of grade III, 4 taxa of grade II, and 12 taxa of grade I. The specific distribution plants were found 27 taxa: 4 taxa of northern part of plants, 12 taxa of southern part of plants, 10 taxa of isolation distribution of plants, and 1 taxon of recently reported Viola betonicifolia var. albescens. The invasive alien plants were identified as 67 taxa. The naturalized index (NI) was 15.12%, and urbanization index (UI) was 20.9%, respectively.
