Fig. 3From: Plastome phylogenomics, biogeography, and clade diversification of Paris (Melanthiaceae)Divergence time estimation based on plastome DNA sequences. Numbers above/under the tree branches represented mean divergent ages and 95% confidence interval of each node. Red arrows indicate the calibration points for the molecular dating. Divergence time and the timeline are indicated in million years (Mya)Back to article page
