Blind Prickly Pear
Common in lower elevations of western/southwestern Texas and much of Mexico's Chihuahuan Desert, this is the only native prickly pear in the region without long spines. Instead, brown hair-like glochids grow in the areoles, which if touched, can be quite painful and difficult to remove. This one was photographed just north and below the Chisos Mountains in Big Bend National Park in Brewster County, Texas.
