Clumping barrel cactus from the Valley of Tehuacán with reddish flowers. May grow to form low mounds several feet wide in old age in habitat, though probably not in cultivation in your lifetime. 13 acute ribs, 4-6 central spines (variable length to 3"), 12-20 radial spines (sometimes more like bristles).

Found in Puebla and Oaxaca. Shares territory with the similar Ferocactus robustus (yellow flowers) which has greener, narrower stems; fewer ribs; and less extensive spines. Recently renamed from Ferocactus to Parrycactus, presumably based on DNA evidence.
