Phylogenetics: Bergerocactus is a monotypic genus within the Pachycereinae clade, and may be sister to Nyctocereus (Arias & al. 2005). Bergerocactus emoryi represents a unique tetraploid taxon, with the possibility of hybridizing with Myrtillocactus and Pachycereus in the floristic province of Baja California, where it is endemic.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.
