Matucana madisoniorum f. monstrous

The monstrous shape of this cactus presents anomalies such as asymmetries or lack of thorns, abnormalities that will never present the same in plants, making each of them very special, unique and for this reason very appreciated by collectors around the world. In its normal form it is a globose and solitary cactus that with time can tuft at the base. It has a green stem that can vary and fade towards gray and bluish. Its thorns may be few or even non-existent while in some cases they may be numerous. Its intense red flowers bloom at the top of the stem, giving the plant a particular appearance. The name of this cactus is chosen in honor of Marshall P. Madison.
