Discussion
Sclerocactus pubispinus is very similar to S. spinosior, and the two taxa have historically been confused. In addition to the features noted in the key, S. pubispinus generally has one dark red, robust, hooked central spine and two less stout, hooked central spines that are initially dark red and quickly fade to white, and flowers that are usually yellow to bronze. By contrast, S. spinosior generally has three stout, dark red central spines, the abaxial spine hooked, and flowers that are usually purple to cream. However, in juvenile (pre-reproductive) stages, the species are nearly indistinguishable.
