Mammillaria baumii

A small clustering cactus from northeastern Mexico, densely covered in fine white radial spines and bearing scented yellow flowers. It comes from warm limestone scrub with a summer rainy season and a dry, mild winter, and is grown like other soft-spined Mammillaria: bright light, a gritty mineral mix and a dry winter rest.
