There are eleven to 16 sharp-edged ribs that are notched. The white areoles on it are 2.5 to 3 centimeters apart. The strong, awl thorns that arise from them are gray and have a darker tip. The single central spine is 3 to 6 inches long. The eight to twelve radial spines have a length of 1 to 3 centimeters.

The funnel-shaped to tubular, white flowers appear on the side of the shoots and open at night. They become up to 14 centimeters long.
