Strict consensus trees from parsimony ratchet analyses of the PRK (number of MP trees, 3856; MP tree length, 1460; CI, 0·45; RI, 0·78; RC, 0·35) and RPB2 (number of MP trees, 3742; MP tree length, 1562; CI, 0·52; RI, 0·79; RC, 0·41) data sets. Values above the branches are MP/ML bootstrap percentages. Groups recognized in the classification of Dransfield et al. (2005, 2008) and major clades mentioned in the text are indicated. The asterisk indicates that the core arecoid clade in this tree also includes tribe Iriarteeae. Labels with a dotted line indicate that the group is only resolved in part.
