The genus Tilia is characterized by linear form bracts of which the lower part is attached to the peduncle of a cyme. This character is distinguished from the others genus of Malvaceae. The purpose of this study is verifying the phylogenetic relationship of genus Tilia. Phylogenetic analyses were conducted to evaluate relationships of 10 taxa of Tilia in Korea and Japan including one outgroup (Gossypium hirsutum). The molecular phylogenetic analyses were conducted with sequences based on ITS, trnL-F and rpl32-trnL region. The combined data result of ITS, trnL-F and rpl32-trnL was formed by 6 clades. T. kiusiana situated as the most basal clade. T. amurensis, T. taquetii and T. rufa are composed a clade. T. koreana, T. insularis and T. japonica was formed independent clade. T. insularis has the closest relationship with T. japonica. T. miqueliana, T. mandshurica, and T. megaphylla are composed a clade and showed a sister relationship than other species.
