Wiggins'cholla (Cylindropuntia echinocarpa)
Description
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.Silver cholla is a large, tree-like cactus which may exceed 2 m (6.6 ft) in height. Its stems and branches are made up of cylindrical 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 width of the tubercles is less than twice the length, which helps to distinguish it from buckhorn cholla (Cylindropuntia acanthocarpa), which occurs in a similar geographical distribution
