}}
Phylogenetic studies have shown the genus to be monophyletic, and most closely related to the genus Rhytidocaulon. Marginally more distantly related is a sister branch comprising the genus Pseudolithos and the widespread Caralluma stapeliads of North Africa.[5] {{commons category|Echidnopsis}}External links
