Sclerocactus brevihamatus

A small globular hooked-spine cactus (formerly Ancistrocactus brevihamatus) from the Edwards Plateau edge and Rio Grande country of Texas into Coahuila and Nuevo León. It grows in limestone grassland and scrub, takes summer heat well and needs a dry, cool winter and a very mineral mix to avoid rot.
