Phylogenetics: Phylogenetic analyses using cpDNA (Sánchez & al. 2014) showed the monophyly of Echinocereus but excluding E. pensilis J.A.Purpus. Echinocereus pensilis was segregated as the monotypic genus Morangaya G.D.Rowley as sister to Stenocereus (A.Berger) Riccob., Myrtillocactus Console, Escontria Rose, and Polaskia Backeb. The monophyly of Echinocereus has been corroborated by the analysis of morphological characters (Sánchez & al. 2015, 2018). Echinocereus is one of the most diverse lineages of the family and species delimitation is often challenging due to extreme morphological variation in some species complexes.A

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.
