Notes:- This pleasing species is, unfortunately, not common in
collections. It is of rather distinctive appearance, having some
resemblance, at first sight, to M.zacatecasensis. However, it is
easily distinguished from this latter by its pure white radial spines. It appears to present no cultural difficulties and appears to grow from seed readily. It belongs to the group of early flowering Mammillarias, the blooms usually appearing during the latter part of March.
