The stems are globular to cylindrical, yellow-green to dark bluish green of flabby texture like Echinocereus, up to 15 cm tall, 10 cm in diameter; distinctly ribbed.
Both radials and centrals spines are white or yellowish and brown radials 10-30 mm long. Tubercles absent.
Environment
Mammillaria species like most cacti they're drought tolerant and need very little care and attention to grow well . Plenty of sunshine will keep this cacti more than happy. Provide bright, even light to encourage tight growth and flowering. Some shade during a hot summers day can be helpful to prevent sunburn.
Allow the soil mix to become nearly dry between watering, but then water thoroughly. Suspend watering in the winter, but mist occasionally. Not enough sunlight and over-watering are common mistakes.
Use pot with good drainage and a very porous potting media.
Feed every 4 weeks with a high potassium fertiliser during summer
