Phylogenetic tree and chronology of divergence times based on ITS as estimated using Bayesian methods implemented in BEAST.

<p>Assignments into clades A (light red; A1, A2, A3 and A4 represent <i>M</i>. <i>celtidifolia</i>, <i>M</i>. <i>nigra</i>, <i>M</i>. <i>rubra</i> and <i>M</i>. <i>serrata</i>, respectively), B (light pink; B represents <i>M</i>. <i>alba</i>), C (light sky blue; C represents <i>M</i>. <i>notabilis</i>), D (light blue, D1 and D2 represent <i>M</i>. <i>mesozygia</i> and <i>M</i>. <i>insignis</i>, respectively) and an outgroup (light green) are shown. Values represent the divergence times with the 95% highest posterior density intervals shown in parentheses.
