- Taxonomy
Phylogenetic studies have shown the genus to be monophyletic, and most closely related to the Echidnopsis genus which inhabits the same region. Marginally more distantly related is a sister branch comprising the Pseudolithos genus and the widespread Caralluma stapeliads of North Africa.[4]
