Notes

Confirmed as monophyletic by Butterworth & al. (2002) and Vázquez-Sánchez & al. (2013). The generic status and limits of Echinomastus need further evaluation because it was found polyphyletic by Vázquez-Sánchez & al. (2013). Revisions/monographs by Heil & Porter (1994) and Hochstätter (2005).
