Mammillaria crucigera

A small, clustering Mammillaria from south-central Mexico with tiny white spines, often in a cross-like pattern, and small purple-pink flowers. It is known from steep, sunny rock in seasonally dry country and is slow and rot-prone in cultivation, so a mineral mix and a dry winter are essential.
