The cylindrical, blue-green shoots are later light glaucous green and have a diameter of 6 to 9 centimeters. There are four to five deeply notched, high ribs . The areoles sitting in the notches are far apart. The usually three to four spreading, conical thorns emerging from them are thick to onion-shaped at their base. They are yellow with a black tip or black and up to 7 millimeters long.[3] The slightly pink flowers are 20 to 22 centimeters long. The egg-shaped fruits are up to 10 centimeters long and red.
