There are 13 to 18 sharp-edged ribs , which are divided into ax-shaped cusps. The gray areoles are located in the notches and are about 2 centimeters apart. From them arise slightly curved, white to brownish thorns . The one to three central spines, which can occasionally be missing, are curved at their tips and 2 to 5 centimeters long. The six to 13 radial spines, which are mostly arranged in a comb shape, are up to 1 centimeter long.

The funnel-shaped, parsley-scented, white to magenta flowers open at night. They become 10 to 20 centimeters long. Your flower tube is slightly curved. The outer bracts are spread out, the inner ones curved upwards. The spherical fruits are semi-dry.
