Chromosome numbers of eight Carex taxa in Korea (Cyperaceae)

In the flora of Korea, Carex L. is one most species-rich genera. Among nearly 157 taxa, less than 30 have had their chromosome numbers reported. We report meiotic eight taxa from Korean populations, which include first count for C. accrescens Ohwi (n = 37II) and investigations populations three taxa: bostrychostigma Maxim. 22II), lanceolata Boott 36II), paxii Kük. 38II). species, counts observed in study are included within variation ranges previous numbers. However, 22II) planiculmis Kom. 29II) assigned new known to holocentric chromosomes, lacking visible primary constrictions exhibiting great variance its number. Further diversity chromosomes will provide basic information with understand high species genus.
