Discussion
Sclerocactus polyancistrus is the only member of the genus that truly lacks papillae on the style, and its style possesses grooves, somewhat reminiscent of Ferocactus. It is easily recognized by its massive stem size (relative to other species of Sclerocactus), large flowers, and numerous hooked central spines (five to nine).
