The consensus phylogenetic tree derived from Bayesian Inference (BI) analysis based on nrITS sequence data. Bootstrap support values from Maximum Likelihood (ML) analysis (ML > 60, left) and Bayesian posterior probabilities (PP > 0.70, right) are indicated above the branches. Strongly supported values (BS > 80, PP > 0.95) are shown in bold. Small boxes represent capitulum morphology: red indicates inner phyllaries ca. 5 and ligulate florets usually 5–6, blue indicates inner phyllaries ca. 8 and ligulate florets 8–12, and gray indicates uncertain characteristics.
