Bayesian inference majority-rule consensus tree of 86 Orobanche populations inferred from three concatenated cpDNA regions (matK, rps2 and trnL-trnF). Tip labels consist of the taxon name (if not included in a sidebar), the collection number and the herbarium accession numbers if available. Posterior probabilities >0·9 are shown in bold for nodes with >70 % maximum likelihood bootstrap (BS) support and in italics if BS support is < 70 %. Some host associations are indicated in blue (Asteraceae) or green (other) to the genus or higher taxonomic level; for others, see Fig. 1. Informally named groups are given in purple. Outgroups are not shown.
