Abstract

<p>Four species of the genus Carex from Kuroshima Island were used for karyomorphological studies. Intraspecific aneuploidy, 2n = 38 = 19II, 39 = 19II + I, and 58, were found in C. atroviridis var. scabrocaudata and these chromosome numbers are reported for the first time in this study. Chromosome numbers of C. multiflora var. pallidisquama (2n = 72), C. tokarensis (2n = 26 = 13II), and C. tsushimensis (2n = 32 = 16II) were determined for the first time. Carex atroviridis var. scabrocaudata and C. tokarensis are endemic to the Kuroshima and Tokara Islands. Our results suggest a close relationship among C. atroviridis var. scabrocaudata, C. conica, and C. oshimensis. Carex tokarensis is also considered to be closely related to C. reinii, because these two species had the same chromosome number.</p>
