Subspecies, varieties, forms and cultivars of plants belonging to the Ferocactus pilosus group

  • Ferocactus piliferus f. flavispinus (hort. ex Schelle) G.Unger: Yellow spined form.
  • Ferocactus pilosus (Galeotti ex Salm-Dyck) Werderm.: Plants solitary or forming massive clumps. Central spines bright red, yellow, or a mixture of both. Radial spines usually reduced to many whitish bristles or absent. The subsp. 'pilosus'' has additional wispy and hairy white spines. It appears also to have brighter red, bigger and thicker central spines compared to more common variety.
  • Ferocactus pringlei (J.M.Coult.) Britton & Rose: With only red acicular spines and none (or very few) hairy white spines. However it look very similar to subs. pilosus and are linked one to each others by populations of plants with intermediate characteristics. Nowadays both are thought to belong to a unique polymorphic species with some individual covered in fine white hairs, while others do not.
  • Ferocactus stainesii (Salm-Dyck) Britton & Rose: The Mexican fire barrel cactus is one of the most most spectacular species in this genus. After several (40/50) years plants it can reach about 2 meter high.
