Cytotaxonomical studies were conducted on three species of the genus Ligustrum in the Ryukyus. This is the first report of the chromosome number of L. tamakii and L. liukiuense, which are endemic and semi-endemic to the Ryukyus, respectively, as 2n=46. Considering the most common basic chromosome number of the family Oleaceae, L. tamakii and L. liukiuense were regarded as diploid based on x = 23. As with these two species, all L. japonicum individuals had a chromosome number of 2n=46. This chromosome number is a new count for L. japonicum and is clearly inconsistent with previous studies in which L. japonicum has been reported to have a chromosome number of 2n=22 and n=22 (i.e., 2n=44) based on x = 11.
