Taxon standing
Category A. The genus is monophyletic based on a complete or very comprehensive phylogenetic study, and a phylogeny-based taxonomic synopsis was published.A
Notes
The sister relationship of Peniocereus subg. Pseudoacanthocereus and Acanthocereus has been shown several times with high statistical support from plastid data (Nyffeler 2002; Arias & al. 2005; Korotkova & al. 2017). Based on these results, Acanthocereus is only monophyletic if it also includes Peniocereus subg. Pseudoacanthocereus. Therefore, a new circumscription of Acanthocereus now including the nine erstwhile Peniocereus subgen. Pseudoacanthocereus species was provided by Korotkova & al. (2017).B
