Fig. 4From: Plastome phylogenomics provide new perspective into the phylogeny and evolution of Betulaceae (Fagales)BEAST chronogram of divergence times for Betulaceae based on CDS data. Fossil calibrations are indicated by red boxes. Numbers above the tree branches represent median divergent ages and 95% HPD intervals. The blue bars represent the 95% highest posterior density of node agesBack to article page
