Mammillaria bocasana f. crestata

The crested form of this cactus has the typical fan arrangement, while keeping its soft and candid appearance. It is not uncommon to find the plant grafted, as this helps the development and growth of the cactus otherwise very slow. In its normal form Mammillaria bocasana is known by the name "Powder Puff Cactus" for its silky white hairs that cover it entirely like a cotton ball. Generally, its spherical stems grow in clusters and brownish hooked thorns sprout at the ends of the tubercles.
