Fig. 4

BEAST-derived chronogram of Opisthopappus based on haplotypes. The red branches represent haplotypes of O. taihangensis and the blue branches represent haplotypes of O. longilobus. Blue bars at nodes represented the 95% highest probability density (HPD) for the age of that node. The estimated divergence time (indicated by a five-pointed star) referred to Time Tree (http://www.timetree.org/) of the most recent common ancestor (tMRCA) of Opisthopappus and the outgroup was employed for calibration. Divergence times with 95% HPD and posterior probabilities (> 0.5) were labeled above and under nodes, respectively
