Discussion

A dominant cholla of the Chihuahuan Desert, Cylindropuntia imbricata var. imbricata is wide- ranging and variable in several characters; it is generally shorter and more spiny northward (there often referred to as Opuntia arborescens). The species appears to be spreading northeastward in Oklahoma and Kansas as a result of cattle ranching activities. In Arizona, New Mexico, and Mexico, var. imbricata intergrades with C. spinosior. Northward, var. imbricata hybridizes with C. whipplei (= C. ×viridiflora).
