Phylogenetics: Vázquez-Sánchez & al. (2013) found Ferocactus in its current circumscription to be vastly polyphyletic, and the same is true for sect. Bisnaga. The Ferocactus clade found by Vázquez-Sánchez & al. (2013) also includes the genera Leuchtenbergia, Glandulicactus, Stenocactus and Thelocactus, corroborating the results of a much less dense sampling by Hernández-Hernández & al. (2011). The Ferocactus clade is morphologically characterized by pericarpels with scales and ribbed stems, and Vázquez-Sánchez & al. (2013) suggested expanding Ferocactus to embrace the genera just mentioned is the best taxonomic solution to make Ferocactus monophyletic, yet Leuchtenbergia is the oldest name of this assemblage and would have priority, unless the name Ferocactus is conserved.A
