“…In Korean Eleocharis, Oh (2007) and Park et al (2016) recognized 13 or 15 taxa, respectively. Oh and Lee (1997) and Oh (2000) classified Korean taxa into two sections (Limnochloa (P. Beauv. & T.…”

Eleocharis R. Br. (Cyperaceae) is characterized by unbranched culms, one terminal spikelet, bisexual flowers, and bristly perianths, occurring mainly in circumboreal marshes and wetlands. There are about 250 species worldwide, and 15 taxa in Korea have been recognized. Chromosomes in Cyperaceae are known to be holocentric, missing constricted centromeres during cell division. For the first time, we report the chromosome counts of Eleocharis from Korean populations of E. attenuata f. laeviseta (Nakai) H. Hara (2n = 20); E. parvula (Roem. & Schult.) Link ex Bluff, Nees & Schauer (2n = 10); E. ussuriensis Zinserl. (2n = 16); and E. valleculosa var. setosa Ohwi (2n = 16). The populations exhibit variations in their chromosome sizes from ca.1.7 μm to ca. 6 μm, categorized as gradient and bimodal karyotypes. The karyotypes observed are congruent with previous phylogenetic groups proposed. To clarify the traditional and phylogenetic classification of Korean Eleocharis, further taxonomic and chromosomal investigations with additional taxon sampling efforts are required.

“…Thirteen taxa of Eleocharis R. Br. are distributed in Korea (Oh and Lee, 1997;Oh, 2006;Kang et al, 2015 (González-Elizondo and Peterson, 1997;Smith et al, 2002). This species is distinguished from taxa of Eleocharis by having small fusiform tubers and style base confluent with apex of achene (Svenson, 1929;González-Elizondo and Peterson, 1997;Smith et al, 2002).…”

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.
