This exemplar of monstrous cactus presents anomalies such as asymmetries, deformations or even lack of thorns that make it unique in its kind as you will never find two monstrous plants identical in their appearance. In the normal form M. cv. Ginsa Maru has a green globose stem with lanate tubercles. At the tips of the tubercles thin white spines and also more robust spines of reddish-brown colour emerge. Its flowers are intense pink.
