Description: it is a small cactus, usually solitary, globular or cylindrical (clusters of stems can be seen in cultivation)
Stem: Somewhat cylindrical, slender, about 2 cm wide and 5-7 cm high, obscured by the spines. Stem and tubercles without latex. The axil is naked.
Spines: 60-80 radial spines (less than in M. herrerae which has 100 or more), white, fine and interlacing. No central spines.
Roots: Taproot
Flower: 3,5 cm long and wide, white (rarely with a pinkish flush when grown in full sun). Flowering period (in Europe): April-May
Fruit: Whitish, retained within the spines, but not within the plant body. (see: cryptocarpy).
Seeds: Black.

Cultivation and Propagation: This plant is not famous for being easy to cultivate, but in good conditions with excellent ventilation, it grows without difficulty. It is especially sensitive to over-watering. So careful watering and an open mineral potting soil are a must. Avoid the use of peat or other humus sources in the potting mixture, and eventually add some limestone. Can be sensitive to frost (but if dry they are resistant to -5° C). It requires maximum sun exposure to reach its full potential, and to achieve success in flowering. A winter rest that allows the plant to shrivel (perhaps losing up to 25% of its summer height) will encourage flowering and long time survival. Be careful to encourage slow growth. Provide very good ventilation.
Propagation: Direct sow after last frost. (it usually doesn't produces offsets)
