Comparison of topologies of multiple gene trees. Twenty-five gene trees were reconstructed based on the 77 plastid coding genes, plastome data, and SNP datasets. a Matrix of Robinson-Foulds (RF) distance, which measures the overall topological discrepancy between two trees. The numbers in the x-axis and y-axis represented the gene trees, and the information was showed in Table 2. b PCoA of the RF distance matrix
