The Phylogenetic tree representing evolutionary relationships of four geographically based groups of <i>Dracaena cambodiana</i> populations.

<p>The coalescent times of the most recent common ancestor (<i>T</i>_TMRCA) for overall populations and each group (A, B, C, D) based on IMa2 (★)and BEAST (♦) analyses. The divergence times among the four geographic groups are T0 T1 and T2. Dashed lines corresponds to <i>T</i>_TMRCA. The 95% highest posterior density intervals (95%HPD) are given in parentheses. The unit time is in million years ago (Ma).
