Description: Usually solitary
Stems: Flattened-globose, apex depressed, 1,5 to 8 cm tall and 4-10 cm in diameter. The juice is watery (latex absent).
Tubercles: Conical, soft, flaccid and pliable, rounded apically, dull blue-green, 1-2,5 cm tall, basal diameter 0,7-1,2 cm, axils naked.
Areoles: 1,5-2 mm in diameter circular to elongated
Central spines: Almost always one, (0-)1(-4) up to 1,7 cm long, yellowish to reddish, spreading, 1 hooked, while the second central spine(s) – if present - are straight.
Radial spines: 10-18(-24) slender white 0,8-1,6 cm long straight silky and slightly pubescent.
Flowers: Unlike most mammillarias, this cactus bears large funnel-shaped flowers up to 4 cm in diameter, white with pink mid-veins. Pericarpel green 3-5 mm long, tepals lanceolate, filaments whitish to pinkish-green, style pinkish-green up to 2 cm long, stigma lobes 6-10 greenish.
Blooming season: March to May
Fruits: up to 2,2 mm long, club-shaped red. The fruits are juicy.
Seeds: 1.2-1,4 mm large, black.

Cultivation and Propagation: Very easy to grow. Watering Needs: It needs regular water, but do not water again until dry. Also, it is a species that is dormant in the winter and requires very little water (maybe even none) during the cold months. Frost Tolerance: Light frost protection required. Minimum of 5º C for safe growing (but hardy down to -8°C or less.). Sun Exposure: In spite of its preference for shade in the wild, in culture, good exposure to sunshine will favour good spine development. It can get sunburned if moved from shade/greenhouse into full sun too quickly. During the spring it may be able to take full sun until the heat arrives at the end of spring. In an area that has hot afternoon sun, it may be able to take full morning sun, but requires afternoon shade or afternoon light shade. If grown correctly, it will reward the grower with generous displays of yellow flowers. Clumps will be formed quite readily over a few years. Spider mites are especially attracted to this species, but often are controlled with overhead watering. Care with repotting is needed, as the thick taproot is easily damaged.
Propagation: Seeds or offsets that appear at the base; leave them attached to form a cluster, or wait until they are 1/3 the size of the parent and then detach and plant.
