Phylogenetic relationship of Echinocactus inferred with cpDNA plus morphology. Bayesian 50% majority rule consensus tree. Values in nodes correspond (left to right) to bootstrap values from maximum parsimony (mpb) and posterior probabilities (pp). The black star indicates the HEA clade and its three subclades Astrophytum, Echinocactus and Homalocephala highlighted.
