Mammillaria picta

A small clustering Mammillaria from the Sierra Madre Oriental of northeastern Mexico. It has fine white radial spines and dark-tipped centrals. It usually grows sheltered under shrubs in oak and scrub country around 1,300 to 2,000 m, so it likes bright light that isn't brutal, summer rain and a cool, dry winter.
