  • Copiapoa cupreata (Poselg. ex Rümpler) Backeb.
  • Copiapoa dura F.Ritter: Solitary, or forming dense clumps. The stem is firm, dark tannish-green to very dark-purple and woolly apically. The spines are very strong maroon-reddish to pure black, straight or (usually) somewhat curved upward.
  • Copiapoa echinoides (Lem.) Britton ex Rose in Britton & Rose: small growing plant with dark purplish-brown stem and thick curved amber-maroon to black spines. This appears to be a very variable species.
