We report on polyploidy, karyotypes, and cytogeographical distribution of two species of native agamospermous Taraxacum in Japan. Taraxacum venustum had two polyploid numbers of 2n=3x=24 and 2n=4x=32. Four karyotypes were found in tetraploid plants. In T. shikotanense, there were seven chromosome numbers: 2n=47 (hypohexaploid), 48 (hexaploid), 56 (heptaploid), 64 (octoploid), 72 (nonaploid), 80 (decaploid), and 88 (undecaploid). Our study reveals that some races in both T. venustum and T. shikotanense can be differentiated according to their polyploidy and karyotypes.
