About plant names...

Buckthorn cholla (pronounced “koy-ya”) is a North American native.

Identification: These plants may appear shrub-like, or take a shape more like a tree. They are 3-13' (1-4 m) high. Stem segments, which can be green or purple, may be sparsely or densely branched. Each segment is 4-20" (10-50 cm) long and ¾-1" (2-3 cm) around. The areoles—little bumps with the spines—are elliptical to round, and have a fuzz that is light-colored at first and darkens with age. Spines are in groups of 6-20 or more, white to gray, tipped with yellow, about ⅝" (1.6 cm) long. Flowers may be yellow, bronze, or brick red, and are ¾-1" (2-3 cm) long. Fruits become tan, and are inconspicuous.

Buckthorn cholla is similar to staghorn cholla:
