A large shoot and a taproot are formed. The six to ten ribs are broad and flat at their base and notched above each areole. Central spines are usually not present, but sometimes one is formed. The usually five bent-back, light brown marginal spines have a darker tip and turn gray with age. They are up to 3 centimeters long.
The funnel-shaped, creamy white flowers are up to 3 centimeters long and reach a diameter of 4 centimeters. The gray-green, bluish-tinged fruits are elongated. [3]
