Figure 4 in A TIME-CALIBRATED PHYLOGENY OF VERBESINA (HELIANTHEAE - ASTERACEAE) BASED ON NUCLEAR RIBOSOMAL ITS AND ETS SEQUENCES

Figure 4. Time-calibrated Bayesian inference tree generated using concatenated internal and external transcribed spacer data. The values at the nodes indicate mean divergence dates, and the horizontal bars indicate 95% highest posterior density ranges for the age at each node. The green bar indicates the consensus age of the closure of the Panama Isthmus (age based on Leigh et al., 2013; O'Dea et al., 2016).
