Notes

Phylogenetics: Stenocereus is a monophyletic genus if S. aragonii and S. eichlamii are excluded. The exclusion of S. dumortieri is still poorly supported, while retention of S. yunckeri is ambiguous; contains at least four clades (Alvarado-Sizzo et al. 2018; Alvarado-Sizzo et al. 2019; Arreola-Nava & Terrazas 2003). Stenocereus is one of the most diverse in Echinocereeae, in stem and flower morphology. Its greatest taxonomic diversity is found in south-central Mexico.A
