description

Pelecyphora strobiliformis grows with spherical or depressed spherical bodies that have a diameter of 4 to 6 centimeters. Your warts lying on the surface overlap each other. They are slightly keeled and triangular in shape. The warts are 8 to 12 millimeters long and 7 to 12 millimeters wide at their base. The 7 to 12 flexible, whitish, non-persistent thorns are arranged somewhat comb-shaped at the tip of the wart and are 5 millimeters long.

The magenta-colored flowers reach a diameter of 1.5 to 3 centimeters. The small fruits are hidden in the parting wool. When ripe they dry up and eventually disintegrate over time.
