DNA sequence data of the rbcL gene, the matk gene, and the internal transcribed spacers of nuclear ribosomal DNA involving 14 species representing the Cercidiphyllaceae. Eupteleaceae. Platanaceae, Tetracentraceae. and all the subfamilies of the Hamamelidaceae have been investigated in the present study.
