Discussion
Stenocereus thurberi is a common columnar cactus of the Sonoran Desert, throughout Baja California and the islands of the Gulf of California and in the west-coastal vegetation from Sonora to Sinaloa. In Mexico, where S. thurberi is arborescent, it has a very short trunk to 0.5 m, exceeds 12 m, branches more than in northern populations, and can have as few as 12 ribs. Tall specimens of S. thurberi occur where the plants grow in taller vegetation, hence competing with small trees for sunlight (A. C. Gibson and P. S. Nobel 1986).
Stenocereus thurberi belongs to the largest clade of Stenocereus wherein all species possess dark red or brown, glandular areolar trichomes (A. C. Gibson 1988). The group of species most closely related to S. thurberi have the interareolar transverse fold, a distinctive mark that persists after the ribs become fully expanded.
