 | Tree Cholla, Coyonostyle, Walking-stick Cholla, Silverspine Cane Cholla Opuntia imbricata var. argentea Cactaceae Tree cholla prefers the deep sods and desert bottomlands at only 220 to 260 feet of elevation. It is a small, often thicket-forming shrub which may be distinguished from var. imbricata by its stouter glaucous joints, smaller tubercles and silvery spines with silvery sheaths. It is endemic to a very limited area in Brewster County in Big Bend National Park near Mariscal Mountain and perhaps also in adjacent Mexico. Consequently it is on the TOES V watch list, meaning that it has a restricted range in Texas, or that it has a low population, and needs attention to insure that it does not become threatened or endangered.
