Node numbers refer to Figure 2A. Mean ages and 95% HPD intervals of divergence times are in millions of years before the present. Age estimates were compared with earlier dating studies for the Annonaceae. Bayesian PP are also indicated. C1 and C2 represent the calibration nodes (see texts for details).
