Stems: Solitary flattened globose, blue-green, up to 5 cm high and in diameter.
Spines: About 12-16, thin, bristle-like radial spines, slightly pubescent with darker tips, up to 6 mm long. Central spine: not present or 1, straight, needle-like, darker, up to 6 mm long.
Flowers: White with pinkish midveins, very early in the season, February/March.

Origin and Habitat
Coahuila, Mexico.
Altitude: 1000 to 1230 metres above sea level.
Habitat: This plant is a mud crack dweller, growing almost sunken in cracks in the dry lake at the Laguna de Viesca.
Cultivation and Propagation
This species has few special demands. Whatever view one adopts, it is worth a place in every Mammillaria collection. The only problem is that it is very slow growing, a plant for patient growers.
Like all thick-rooted species, it requires careful watering (rot sensitive), and patience to match its slow growth. During the winter rest, the plant may pull near the surface of the potting mix.
Propagation: Direct sow after last frost. (it usually doesn’t produces offsets).
