Opuntia blakeana Rose, Contributions from the U. S. National Herbarium 12: 402, 1909
Opuntia blakeana is a small, spreading Sonoran Desert Plant; the cladodes are typically dark green but may have brown or purple tints. The spines are short and light or dark brown, (0)2 or 3 per areole; the pad color and brown spines create a handsome plant. Pads may stack up 2- or 3-foot-tall from prostrate branches. The plants have limited similarity with O. camanchica and the flowers and fruits are similar to those of O. phaeacantha. The species occurs in the greater Tucson, AZ area. See the original citation.
