  • Many plants take up soluble silica from the soil, and they deposit in plant tissues. Silica bodies are most commonly found in the leaf epidermis. Silica body is important factor in growth and development of plant. It help to maintain rigidity in stem and linear leaves, and its content may be correlated with resistance to fungal disease. In this study, several morphologically distinctive forms of silica bodies on Cyperaceae in Korea are recognized, which are eventually classified into two groups. Silica body type of first group (Rhynchospora, Fuirena, Scleria, Carex, Eriophorum) is A-type, which is conical in shape. Silica body type of second group (Cyperus, Scirpus, Eleocharis, Fimbristylis, Kyllinga, Bulbostylis, Lipocarpha) is B-type, which is conical in shape with numerous satellite body. These types are consistent enough to use as characters in taxonomic studies within genus. Silica body type may be associated with habitat: the species in dry region have A-type, whereas the species in wet region have B-type. These results suggested that shapes and presence or absence of silica body might be valuable to systematic analysis.

  • 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.

  • A newly naturalized plant, Carex scoparia Schkuhr ex Willd. var. scoparia, was found in Mt. Hanseok, Injegun, Gangwon-do, Korea. It belongs to sect. Ovales Kunth and had been known from North America, and was introduced into Europe and New Zealand. This species distinguished from related taxa in Asia, Carex maackii Maxim. and Carex leporina L., by pistillate scales lanceolate and having large perigynia. We propose the new Korean name, 'Han-seok-sa-cho', based on its first collecting place. We also provide descriptions for morphological characters, illustrations, photographs and keys to allied taxa.

  • We report S. caricina (R. Br) Benth. (Cyperaceae) as an unrecorded species from Sinan-gun, Jeollanam Province on the Korean peninsula. This taxon was known to be distributed mainly in southeast Asia, China, Japan, and the northern part of Australia. S. caricina is distinguished from other species of the genus Scleria in Korea by having congested inflorescences, 3-toothed pistillate scales at the apex, and enclosed achenes in 2 scales. The new Korean common name, 'Ae-gi-gae-ol-mi', is given considering the small-size of the plants. A description based on the morphological characters and the illustrations of this species are provided with a taxonomic key to the species of Scleria in Korea.

  • A newly recorded species, Fimbristylis hookeriana Boeckeler, was found in Gyema-ri, Hongnongeup, Yeonggwang-gun, Jeollanam-do and Munyeo-do Is., Gunsan-si, Jeollabuk-do, Korea. Fimbristylis hookeriana is closely related to F. dichotoma, which has ovoid spikelets, deciduous scales, pubescent culms, and short style. However, this species is distinguished by very narrowly ovoid spikelets, persistent scales, glabrous culms, and long style. We propose a new Korean name, 'Ba-Wi-Ha-Neul-Ji-Gi', meaning that this inhabits on dried rocks near seashore. Redescription, illustrations, photographs, table, and a key to species of the Fimbristylis Vahl in Korea are provided.

  • 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.

  • 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.

  • Eleocharis parvula (Roem. & Schult.) Bluff, Nees & Schauer (Cyperaceae), was found in Ganghwa-gun, Incheon Metropolitan City in Korea. This species is distinguished from related taxa in Korea by its small fusiform tubers, culms without septa when dry, 3-fid stigmas and style base confluent with the apex of achene. This taxon was named 'Gaet-ba-neul-gol' in Korean based on its habitat. We provide its description, illustrations, photographs and a key to the related taxa in Korea.

  • Author has studied and reported on taxonomy of Korean sedges, using gross morphology, anatomy and epidermal patterns of the leaf blades(1969, 1971, 1973, 1974). This paper is the 6th report of epidermal patterns of leaf blade on sedges and includes 5 genera, Eriophorum, Fuirena, Kobresia, Rhynchospora and Scirpus. The author proposed to find epidermal patterns of leaf blades as an important taxonomic characteristic of sedges classification. The result of this study, the elements of leaf epidermis, subsidal cells, silica body, cell wall of long cell, prickles, and arrangement of the elements are considered to be significant characteristics for the identification and classification of sedge.
