There are nine ribs , which are clear on the upper parts of the shoot, but further down are flat and blunt. The elliptical areoles on it are cream-colored to gray and are up to 2.5 centimeters apart. From them arise 14 to 18 gray to whitish, awlish thorns that are darkly tipped. Some of the uneven thorns are spreading and others protruding. The thorns are 1.5 to 7 centimeters long.
