Notes

Monotypic; sampled in several phylogenetic studies, first found as sister to Pachycereus (A.Berger) Britton & Rose (Arias & al. 2005), but without support. Later found nested in Pachycereus, as sister to P. pecten-aboriginum (Engelm. ex S.Watson) Britton & Rose with high support (Hernández-Hernández & al. 2011), yet the whole Pachycereus clade was only weakly supported in this study. Found as sister to Pachycereus in the study of Franco-Estrada & al. (2021), albeit without support. Due to these inconclusive results, Carnegiea is retained here as a separate genus.A,B,C,D
