Karyotypes of six Korean taxa of the genus Cimicifuga were examined. Mitotic chromosome numbers of all taxa examined were diploid with 2n=16; our count of 2n=16 for C. heracleifolia var. bifida is the first report for the taxon. Cimicifuga dahurica, C. heracleifolia var. heracleifolia, C. heracleifolia var. bifida, and C. simplex, which belong to sect. Cimicifuga, have basically identical karyotypes consisting of five pairs of metacentric, two pairs of submetacentric, and one pair of acrocentric chromosomes. These taxa, however, show differences in the number and position of secondary constrictions (or satellites), and can be distinguished from one another at the species level. Two morph types of C. simplex in Korea differ in the position of secondary constriction on the short arm of the the first pair of submetacentric chromosomes; in these morph types, there appears to be association between karyotypes and morphological characters including plant height, leaflet pubescence, inflorescence shape, and pedicel length. Cimicifuga biternata and C. japonica of sect. Pityrosperma, which are morphologically closely related and sympatric in distribution, share an identical karyotype. However, karyotypes of these two species markedly differ from those of sect. Cimicifuga in having a pair of subtelocentric chromosomes instead of submetacentric ones.
