Figure 1.

A combined phylogeny of the tribe Astereae based on the Bayesian inference (BI) and maximum-likelihood (ML) analysis of chloroplast protein-coding genes. The BI and ML analyses recovered the identical topology. The support values next to the nodes were Bayesian posterior probabilities according to the BI analysis (first value) and bootstrap percentages of 500 pseudoreplicates according to the ML analysis (second value). Four species within the tribe Anthemideae were included as the outgroup taxa.
