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.
Notes
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).
