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.

Carex kamagariensis K. Okamoto was found in throughout the nation. This species is distinguished from other related taxa in Carex sect. Mitratae by pistillate scales with a long arista and achenes constricted above in the middle. A new Korean name, 'Jom-mok-po-sa-cho', is based on its small size and floral character similarity to C. genkaiensis. In this study, a description, illustrations and habitat photos of the species are provided. The key of its related species is also provided.

An unrecorded species, Carex rugata Ohwi, was found in Jeollabuk-do and Jeollanam-do. This species is distinguished from Carex breviculmis R. Br., C. mitrata Franch., C. polyschoena H. Lev. & Vaniot, C. genkaiensis Ohwi, C. formosensis H. Lev. & Vaniot and C. kamagariensis K. Okamoto by having achenes with excavated faces. Carex rugata Ohwi was named 'Ju-reum-cheong-sa-cho' in Korean based on its specific epithet. In this study, a description, illustrations and photographs of the species are provided.

A new species, Carex brevispicula G. H. Nam & G. Y. Chung (Cyperaceae), was found in Korea. Carex brevispicula is similar to the related species C. chungii Z. P. Wang and C. genkaiensis Ohwi in that its achenes are constricted in the middle part. However, C. brevispicula is distinguished from C. chungii as the plants, staminate, and pistillate spikes are shorter and its pistillate scales are pale green; C. brevispicula is distinguished from C. genkaiensis by its awned staminate and pistillate scales. The scientific name of this new species was based on the fact that its inflorescence is shorter than that of C. chungii. The corresponding Korean name, "Jom-mok-po-sa-cho," means that the plants of this species are smaller than the "Mok-po-sa-cho" types (C. genkaiensis). We hereby provide a description of C. brevispicula, with corresponding illustrations and photographs, a distribution map, and a key of related taxa.
