  • Ferocactus cylindraceus subsp. cylindraceus
  • Ferocactus cylindraceus subsp. lecontei ( Engelm. ) N.P.Taylor
  • Ferocactus cylindraceus subsp. tortulispinus ( H.E.Gates ) N.P.Taylor

In the Red List of Threatened Species IUCN, the type is known as " Least Concern ( LC) ," ie, than not led at risk.
