Acanthocereus (Engelm. ex A.Berger) Britton & Rose in Contr. U.S. Natl. Herb. 12: 432. 1909 sec. Korotkova & al. 2017


Revised by Salvador Arias, Carlos Gómez-Hinostrosa & Héctor M. Hernández


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).A
