This is the first report on chromosome number of the Aster ageratoides complex in Korea, which is one of the representatives of Sino-Japanese elements. Our cytogeographical research reveals that both diploids and tetraploids occur in Korea. Diploids are dominant and widely distributed through Korea including Cheju Island, while tetraploids are limited to the southeastern part of the Korean Peninsula. The leaf shape of diploids shows a clinal variation from lanceolate to ovate toward south. At the south end of this peninsula, lanceolate leaved diploids and ovate leaved diploids are sometimes sympatric in several populations. Tetraploids also have a leaf shape variation from lanceolate to ovate even within a population. The plants with elliptic-lanceolate or lanceolate leaves are identified as A. ageratoides var. ageratoides. Although a taxonomical treatment still waits for further consideration, the resemblance between the ovate leaved plants in Korea and A. ageratoides var. ovalifolius, known as endemic to Japan, is noted.
