Mammillaria spinosissima f. monstrous crested (Monstrous)

In its normal form Mammillaria spinosissima is a columnar cactus that can reach 40 cm in height, characterized by a bright green stem completely covered by multiple spines ranging from white to brown. The crested shape of this wonderful cactus presents the typical compact fan arrangement that will never be the same from one plant to another, with the addition of geometric anomalies such as protuberances or absence of thorns, typical of the monstrosity of the cactus, which together contribute to making this piece absolutely unique, a real jewel coveted by the most experienced collectors!
