FIG. 1. — Majority rule consensus phylogenetic tree for the genus Cranfillia estimated by Bayesian inference on the combined plastid DNA dataset (rbcL, rps4, rps4-trnS, trnL/trnL-trnF), with support values from the Maximum likelihood method and Bayesian inference. Unless mentioned next to the nodes, support values are bootstraps (BS) = 100 and posterior probabilities (PP) = 1. Scale bar is for branch lengths of the phylogram (substitutions/site).
