Notes

Monotypic genus, endemic to the caatinga of Bahia, SE Brazil. Hernández-Hernández & al. (2011) found E. dybowskii within an unsupported Trichocereeae clade, as sister to Rauhocereus (no support), while Schlumpberger & Renner (2012) found E. dybowskii as sister to Micranthocereus densiflorus with 78% MLBS support. Espostoopsis is therefore not closely related to the Andean genus Espostoa, a relationship that had been suggested earlier based on the strong morphological similarities of the two genera.A
