Expansion and contraction of gene families are denoted as numbers with plus and minus signs, respectively. The green numbers in the brackets indicate the estimated divergence time of each node, and the green bars show the 95% confidence interval of divergence time, in millions of years. All the nodes are 100% bootstrap support. A Venn diagram at the side of the tree shows the sharing and specificity of gene families presented between four Ranunculales species.
