Echinocactus texensis is known as the horse crippler since its rigid, flattened stems with their strong spines often lie partly hidden in the prairies of Texas and New Mexico, a danger to any animal that stands on it. It can be found from the far southeast of New Mexico, across two thirds of Texas towards the Oklahoma stateline and the Gulf Coast. Also known as Devil's head and Devil's claw. It's red, globular fruit is sweet and edible.
