Description: Mammillaria nuneziiSN|13783]]SN|20620]] is a solitary or occasionally clustering cactus with showy flowers in June. It is somewhat variable in habit and has a dense spination. Two subspecies are recognized, the nominate subspecies and subspecies bella (Backeb.) D.R.Hunt.
Stem: Robust, globose to cylindrical, pale-green to grey-green , sunken apically, 6-9 cm in diameter and up to 15 cm tall. Without latex.
Tubercles: Conical to bluntly four-angled, about 7-9 mm long and 5-7 mm in diameter, closely set, terete in section.
Parastichy number: 13-21.
Axil: With silky bristles and some wool.
Areoles: Large, white and woolly.
Radial spines: 10-30, stiff, slender, the uppermost being the shortest white, widely spreading, (3-)5-7 mm long.
Central spines: 2-4(-9), unequal usually straight, but one may be hooked, reddish-brown or brown with blackish tips, (7-)10-15 mm long.
Roots: Fibrous.
Flowers: Funnelform, deep pink to magenta 12-15 mm in diameter, narrowly opening. Stigma-lobes green.
Blooming season: It flowers with the freedom of Mammillaria spinosissimaSN|20620]]SN|13783]], in early summer.
Fruits: Club shaped, greenish white tinged with pink, to 25 mm long and 6-8 mm wide, ripens 12-14 months after flowering.
Seeds: Small brown, round to club-shaped, 0,9 mm long and 0,8 mm in diameter.

Cultivation and Propagation: It is a slow growing species of easy culture, recommended for any collection, it doesn't require any special treatment. Water regularly in summer, but do not overwater (Rot prone) Use pot with good drainage and a very porous potting media, keep dry in winter. Feed with a high potassium fertilizer in summer. It is quite frost resistant if kept dry, hardy as low as -5° C (some reports give it hardy to -5°C) Sun Exposure: High levels of light are needed to flower and for good spine development. Can be 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 purple flowers.
Clustering in cultivation after several years and easily flowered. For best results, use a shallow pot, and only use the smallest diameter pot that will accommodate the plant. Sensitive to red spider mite. Overhead watering is helpful in controlling mites.
Propagation: Direct sow after last frost (usually) or division, wait until the offsets that appear at the base of old clustered specimens are 1/3 the size of the parent and then detach and plant.
