The karyotypes of Trillium tschonoskii (2n=20, K2K2TT) collected from four localities of Japan Islands have been studied by means of differential reactivity of H-segments of the chromosomes to low temperature.<br>In all 14 plants examined, 10 pairs of chromosomes were found to be homozygous. But the karyotype of plants from Mt. Aso (Kyushu) was different with regard to chromosome D from that of the plants from the other three localities, Hayakita and Ashoro in Hokkaido and Mt. Tsurugi in Shikoku.<br>The above findings suggested that one of the parental, now extinct, diploid species (2n=10, K2K2) might be differentiated into homozygous local populations. The other extinct homozygous diploid species (2n=10, TT) had hybridized with K2K2 at different localities to give rise to the present T. tschonoskii.
