Pachycereus schottii f. monstrosus
Synonym: Lophocereus schottii f. monstrosus
Common Name: totem pole cactus
Origin: Pachycereus schottii f. monstrosus inhabits alluvial plains and desert riparian environments, in gravelly soils. While the straight species is native to the deserts of mainland Mexico, Baja California, and the extreme south of Arizona, the monstrosus form is only found northeast of El Arco, the midpoint of Baja California.
Description: P. schottii f. monstrosus is a slow growing cactus with a columnar stem - usually trunkless - which basally branches in a candelabra formation. The dark-green and waxy stems reach up to 15 feet in height, possessing 5-9 irregularly-shaped ribs, and unusual, knobby, tubercle-like swellings along the trunk. Unlike the straight species, areoles are few and insignificant, very rarely developing pink flowers.
