Four species of <i>Fagopyrum</i>, two species of <i>Persicaria</i> and one species of <i>Rumex</i> were analyzed for the DNA sequences of their <i>rbcL</i> genes. In addition to these seven species, we analyzed the published or available sequence data of ten related taxa in Polygonales, Plumbaginales and Caryophyllales. By estimating the base substitution rate between each pair of species, and by constructing phylogenetic trees we concluded that: 1) In <i>Fagopyrum, F. cymosum</i> and <i>F. tataricum</i> are much more closely related than expected previously; this confirms the conclusion of Kishima et al. (1995). 2) The new classification of <i>Fagopyrum</i> species proposed by Ohnishi and Matsuoka (1996) based on morphology, isozyme and cpDNA variability is consistent with the <i>rbcL</i> sequences. 3) The Polygonales and the Plumbaginales should be separated from the Caryophyllales as concluded by Giannasi et al. (1992). 4) The separation of <i>Fagopyrum</i> from other genera in the Polygoneae has a solid molecular basis.<br>
