Phylogenetic relationships of Rubieae inferred from Bayesian analysis with a relaxed clock of molecular data from the reduced data set.

<p>Shown is the 50% majority rule consensus tree (for details of the Galium Clade see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0207615#pone.0207615.g002" target="_blank">Fig 2</a>); values above branches are posterior probabilities of at least 0.5 from a Bayesian analysis with molecular data only and values below branches are posterior probabilities of at least 0.5 from a Bayesian analysis with combined data (molecular data, trait data, biogeographical data). Roman numerals indicate clade designations used by Ehrendorfer and Barfuss [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0207615#pone.0207615.ref012" target="_blank">12</a>]. Abbreviations of major clades: <b>A</b>, Asperula Clade; <b>AC</b>, Asperula-Cruciata Clade; <b>AS</b>, Asperula-Sherardia Clade; <b>C</b>, Cymogalia Clade; <b>G</b>, Galiinae Clade; <b>Ga</b>, Galium Clade; <b>K</b>, Kelloggiinae Clade; <b>R</b>, Rubiinae Clade.</p>
