Castellanosia in Cact. Succ. J. (Los Angeles) 23: 90. 1951 sec. Hernández-Hernández & al. 2011
- Type: Castellanosia caineana
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.
Monotypic; sampled by Nyffeler 2002; Bárcenas & al. 2011 and Hernández-Hernández & al. 2011, resolved as sister to Leptocereus (A.Berger) Britton & Rose + Dendrocereus Britton & Rose by the latter, albeit with support <50%.A
