Cylindropuntia echinocarpa is a species of cactus known by the common names silver cholla, golden cholla, and Wiggins' cholla. It was formerly named Opuntia echinocarpa. [1]

Distribution

C. echinocarpa is native to the Southwestern United States and Northwestern Mexico, where it can be found the Sonoran Desert, the Mojave Desert, and Colorado Desert in California and other states. [1]

It commonly occurs in desert dry wash, creosote bush scrub, Joshua tree woodland, and Pinyon-juniper woodland communities.[2] It ranges from Mono County to Baja California.[2]

Description

Silver cholla is a large, tree-like cactus known to exceed 2 m (6.6 ft) in height. Its stem and branches are made up of cylindrical segments, the surface arranged in green tubercles (segments) up to 1.5 cm wide and just under 1.0 cm tall. The fleshy tubercles each bear up to 20 long, straight, grayish or yellowish spines which may be nearly 4 cm long. The tubercles are less than twice the length, which helps distinguish it from Buckhorn Cholla (Cylindropuntia acanthocarpa]]).[2]

The flower is usually greenish yellow, sometimes pinkish or brownish in color.

There is a bumpy, spiny tan fruit is up to two centimeters long and has a foul scent[2] reminiscent of rancid butter. Very few fruits reach maturity, and many immature fruits can often be seen lying on the ground below.[2]

The fruits have white seeds.[2]
