Notes

Phylogenetics: Some phylogenetic analyses and taxonomic studies confirm that Marshallocereus belongs to the Pachycereinae subtribe, but its relationship with Cephalocereus and Pachycereus is still uncertain (Arias & al. 2003; Arias & Terrazas 2006, 2009). Its distribution is one of the southernmost of Pachycereinae, in the Mesoamerican region (Mexico to Costa Rica). The recognition of more than one species is not resolved.A
