Twisted Rib Cactus (Thelocactus setispinus)
Also known as the miniature barrel cactus, this interesting little low-elevation cactus barely reaches 7 inches at its tallest and is usually found in the shady mesquite tree thickets of Central to South Texas. It is easy to identify by its 13 twisted ribs, 10-19 radial spines on each areole with one hooked central spine sticking outward. This golf ball-sized specimen was one of many hundreds found in a wilderness area just outside of Mission, Texas on a cool mid-October evening.
