Sclerocactus blainei S. L. Welsh & K. H. Thorne

Comments

provided by eFloras
Sclerocactus blainei is an unusual species of Sclerocactus, sometimes possessing long ribbonlike spines reminiscent of S. papyracanthus. Sclerocactus blainei differs from other sclerocacti in its range (e.g., S. pubispinus and S. spinosior) in that the flowers are slightly larger and the adaxial central spine is longer than either S. pubispinus or S. spinosior. The central spine number varies, and the number of hooked spines may be as many as six, which is characteristic of S. polyancistrus.
