The usually 2 to 5 central spines are 2 to 5 centimeters long, the 8 to 12 marginal spines are 2 to 12 millimeters long.
The horizontally protruding, purple-colored flowers are slightly curved downwards above the pericarpel. They are up to 7.5 centimeters long and have a diameter of 5 millimeters. The spherical, red fruits reach a diameter of up to 2 centimeters.[1]
