Taxon standing

Category B. The genus is monophyletic based on phylogenetic studies that support the clade based on a sufficiently dense or even complete sampling, or support a monotypic genus as a distinct lineage, but do not provide a new taxonomic treatment at the species level. In many cases, older classical taxonomic synopses or a monographic treatment exist for these genera providing a reliable assessment of the species included.


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
