Franco & al. (2017) found a well-supported Cereus clade, which however also included Praecereus and Cipocereus. Therefore, Cereus is polyphyletic as currently circumscribed, but the authors of that study did not suggest any taxonomic changes to reflect their results. See also notes under Praecereus and Cipocereus. A
