Echinopsis Zucc. in Abh. Math.-Phys. Cl. Königl. Bayer. Akad. Wiss. 2: 675. 1837 sec. Schlumpberger & Renner 2012



Molecular phylogenetic studies indicate that previous taxonomic concepts for the Echinopsis alliance fail to reflect natural relationships (e.g. Schlumpberger & Renner 2012). For a natural classification the following segregate genera are accepted here: Acanthocalycium, Chamaecereus, Echinopsis, Leucostele, Lobivia, Reicheocactus, Setiechinopsis, Soehrensia and Trichocereus. The new generic concept for the Echinopsis alliance, with all the segregate genera accepted, was also already used in the 3rd edition of the CITES Cactaceae Checklist (Hunt 2016).A
