Notes

Phylogenetics: Tapia et al. (2017) have reconstructed the phylogeny of the Cephalocereus group using molecular data from seven plastid DNA regions (petL-psbE, psbA-trnH, rpl16, rpl32-trnL, trnL-F, trnQ-rps16, and ycf1), as well as morphological characters. The Cephalocereus group was recovered as monophyletic with high support values, whereas Neobuxbaumia appeared as paraphyletic. The Cephalocereus group was recovered as monophyletic with high support values, whereas Neobuxbaumia Backeb. appeared as paraphyletic. The authors have therefore proposed to unite all species of Neobuxbaumia, Cephalocereus, and Pseudomitrocereus Bravo & Buxb. in one single genus, for which Cephalocereus is the oldest name.A
