“…1A): The species is distinguished by pistillate scales with aristate apexes and densely pilose perigynia with long beaks and has been recognized as an endemic to Japan (Hoshino et al 2011). Im et al (2008) argued that the species was misrecognized as C. glabrescens (Kük.) Ohwi in Korea, and reported that the species occurs naturally throughout Korea.…”

The meiotic chromosome numbers of six Carex species in three sections are counted; C. miyabei Franch. (n=42 II ) in sect. Carex, C. breviculmis R. Br. (n=31 II , 32 II , 33 II ), C. polyschoena H. Lév. & Vaniot (n=36 II , 37 II ), C. sabynensis Less. ex Kunth (n=27 II , 28 II ) in sect. Mitratae Kük., and C. heterolepis Bunge (n=37 II , 38 II , 40 II ) and C. forficula Franch. & Sav. (n=25 II , 27 II ) in sect. Phacocystis Dumort. The chromosome counts for C. miyabei, C. heterolepis, and C. forficula from Korean populations are verified for the first time.Considered with previous reports, all the species exhibit variations in chromosome number from n=4 to n=36. Contiguous variation in chromosome numbers and non-constricted meiotic chromosomes with holocentromeric nature suggest that aneuploidy and/or agmatoploidy and/or symploidy should have played an important role in the sections.

“…The counts are incongruent with previous reports from Korean populations, 2n = 66, 72 , 2n = 84 ; and a Japanese population, 2n = 90 (Tanaka, 1948). The species has been considered as a Japanese endemic, but recently distributions of the species in Japan and Korea have been known (Im et al, 2008;Hoshino et al, 2011;Park et al, 2016). Although C. miyabei is distinctly characterized pubescent perigynia with long beaks, and pistillate scales with aristate apexes, the species has been often confused with C. glabrescens (Kük) Ohwi for similarity on female spike numbers (more than two), and sharing ecological habitats (Im et al, 2008).…”

“…These species occur throughout South Korea, but the latter grows mainly middle parts of South Korea (Park et al, 2016). Because both favor sunny, sandy places along rivers, it is not hard to find populations of the two taxa close each other (Im et al, 2008;Park et al, 2016). Variations in morphological characters such as perigynium shapes and surface features have made it hard to distinguish them from each other.…”

We report the meiotic chromosome numbers of four Carex taxa from Korean populations. Three are the first reports made on taxa from Korean populations: Carex appendiculata (Trautv. & C. A. Mey.) Kük. (n = 27 I I). Carex L. (Cyperaceae) consists of more than 2,000 species worldwide and is the most species-rich genus in Korea. The species diversity in the genus has been hypothesized to be associated with the chromosome variation, but chromosome information pertaining to Korean Carex taxa is not well known. This report updates the chromosome number inventory on Korean Carex to 24 out of 180 taxa.

“…The species has been considered endemic to Japan until the very recently (Hoshino et al, 2011). However, the species occurs throughout Korea and has been often misidentified as C. glabrescens (Kük) Ohwi (Im et al, 2008;Park et al, 2016). Variations in morphological characters such as perigynium shapes and surface features have made it hard to distinguish the two taxa from each other.…”

Meiotic chromosome numbers of five Carex taxa in Korea (Cyperaceae)

Carex L. (Cyperaceae) is the largest angiosperm genus in the temperate zones with more than 2,000 species worldwide. Unusual chromosome structures, called holocentric chromosomes, have been postulated to contribute to species diversity in the genus. In Korea, this genus has the greatest number of species, but chromosome information as it pertains to the taxa is mostly unknown. Here, we report meiotic chromosome numbers of five Carex taxa in Korea. The following observations are made: Carex jaluensis Kom. (n = 27 I I). Except for C. planiculmis, all of the species exhibit variations in chromosome numbers within individuals and/or taxa. The findings with regard to chromosome number diversity in Carex suggest that chromosome number variation (aneuploidy, agmatoploidy and/or symploidy) plays an important role in the richness of the species in the genus. Further cytological investigations are needed for a better understanding of sedge diversity in Korean flora.
