Bayesian phylogeny of relationships among members of <i>B</i>. <i>asper</i> from different physiographic regions (names as in Fig 1).

<p>Two distinct B. asper lineages are depicted in red (clade A) and green (clade B) branches. Red bars indicate phylogroups supported by the bPTP analysis. Support for each node is shown as posterior probability (PP, Bayesian inference) or Bootstrap value (BS, Maximum likelihood).
