Fig. 2From: The impacts of polyploidy, geographic and ecological isolations on the diversification of Panax (Araliaceae)Divergence times and topologies of Bayesian trees based on whole chloroplast genome (a) and four selected chloroplast genes (b). The values on the left and right of each node are the divergence time (one million years ago) and poster prior support, respectively. Length of each branch is not shown in the two phylogenetic treesBack to article page
