• Opuntia anacantha Speg., Bull. Mus. Hist. Nat. (Paris) 10: 391. 1904.

The name is not fully understood (Hunt 2004) and the view of Kiesling (1998) is followed here with its varietates (CACO, 2021). However, others treat this species as a synonym of either Opuntia elata var. elata or Opuntia stenarthra
