Abstract

<p>Five species of the genus Carex collected from the Yakushima Island were subjected to karyomorphological analysis. Chromosome numbers of C. atroviridis (2n = 70), C. morrowii var. laxa (2n = 38) and C. odontostoma (2n = 30) were determined for the first time. Two taxa endemic to the Yakushima Island, C. atroviridis and C. morrowii var. laxa, had the same chromosome numbers as their allies, respectively. Carex warburgiana had a chromosome number of 2n = 28, which was new for this species. A chromosome number of 2n = 22 for C. grallatoria var. heteroclita corroborates previous reports. A dwarf type of C. odontostoma with a chromosome number of 2n = 30 was also found on the Yakushima Island. There were no karyomorphological differences between the dwarf and common types of C. odontostoma.</p>
