Rooted Maximum Likelihood phylogenetic tree constructed using plastid trnL–trnF spacer sequences. As an outgroup, Lindenbergia sinaica was used. Numbers near branches show ultrafast bootstrap values (values ≥ 75 are shown). The bar represents the amount of genetic change (nucleotide substitutions per site) A summary of backbone (generic) relationships B Phelipanche clade C Orobanche clade. Species names, the country of origin, host species (if available) and GenBank number are included on the phylogeny tip labels.
