Phylogenetic tree estimated from 3 combined mt genes indicates at least 11 origins of parasitism in angiosperm phylogeny. Single best tree estimated from ML analysis of combined atp1 + coxI + matR mtDNA sequence data (-lnL = 43115.38). ML bootstrap support/Bayesian posterior probability values (BP/PP) are shown above all nodes with values >50/0.8. Green branches are non-parasitic, orange branches are mostly hemiparasitic, and red branches are holoparasitic lineages. A star next to a taxon represents the presence of the coxI intron in the sampled species. A filled circle next to an order or family represents the presence of the mitochondrial coxI intron based on literature reports [28].
