Description: Mammillaria microcarpaSN|9210]]SN|9210]] has long been a favorite in living collections. It is sensitive to any excess of moisture and does not do well in cultivation, but will reward the skilled growers with ring of fine rose-purple flowers circling the crown of the plant. This plant is generally known under the name of Mammillaria grahamiiSN|9189]]SN|9189]]. This species is quite common in habitat, but variable throughout the region.
Habit: Simple or budding either at base or near middle, often cespitose, but in small clusters, sometimes 20 cm high.
Stem: Globose, conical to short cylindric, light green, up to 20 cm tall (but usually only 7-8 cm), 2,5-8(-11) cm in diameter.
Tubercles: Small, ovoid to cylindrical, often bases four-angled or flattened from side to side when old, corky when old. Without latex.
Areoles: Dimorphic. The spinous portion, at the tip of the tubercle, is small round or oval, with some white wool at first, but later bare. The floral or vegetative part in the axil is without wool, so the axils are naked.
Radial spines: 15 to 35, radiating evenly from the areole, lying flat upon the surface of the plant, interlocking with those of neighboring areoles and nearly hiding flesh of plant, straight, needle-like, white, sometimes with dark brown to reddish tips, slender, rigid, glabrous, 6 to 12 mm long, lateral ones longest. The upper centrals stand up-right just in front of the upper radials, forming a V if there are two of them, but there may be only one.
Central spines: 1 to 3, yellowish-brown, dark-brown to purplish black, when more than one the lower stouter, 12-25 mm long, the longest one usually hooked and standing out perpendicular to the plant surface.
Flowers: Forming a ring around the new growth near top of plant, 2 to 4,5 cm long, broadly funnel-shaped, opening widely, pink, lavender-pink or reddish purple, sometimes white. Outer perianth segments ovate, obtuse, or conical with brownish midlines and short-ciliate margins; inner perianth-segments longer purplish, slender, sometimes with whitish margins, obovate, acuminate. Filaments pink; anthers pale orange. Style longer than stamens, up to 6 mm long above the stamens, purplish; stigma-lobes 6 or 10, linear, light green.
Fruit: Subglobose to clavate, 12 to 25 mm broad, scarlet, with the dried flower parts remaining upon them. These fruits develop rather slowly, there is a long blooming season, and those started late in the summer remain as small, green, oval structures under the spines until during the winter they dry up without ripening properly at all. For this reason fruits have sometimes been called dimorphic.
Seeds: Black, shining, pitted, almost globose, 0,8 to 1 mm in diameter.
Notes: The degree of difference between Mammillaria grahamiiSN|9189]]SN|9189]] and Mammillaria microcarpaSN|9210]]SN|9210]] is still a matter for debate.

- Mammillaria microcarpa Engelm. in Emory: (Mammillaria grahamii) has 15-35 pale radial spines and 1-3, yellowish-brown to purplish black centrals, the longest hooked. Fruits scarlet. Distribution: USA (Texas, New Mexico, Utah, California and Arizona) and Mexico.
- Mammillaria microcarpa var. auricarpa W.T.Marshall: (Mammillaria grahamii) has pale, radial spines and a yellowish brown hooked central spine. Flowers are 4 cm in diameter, pink, and are followed by golden yellow berries. Distribution: U.S.A. (Arizona).
- Mammillaria microcarpa f. cristata hort.: crested form.
- Mammillaria oliviae Orcutt: (Mammillaria grahamii)
- Mammillaria pseudoalamensis Backeb.: (Mammillaria grahamii subs. sheldonii) variant recognisable from M. alamensis for the absence of central spines, and larger flowers with a characteristic distinctive orange pistil. Distribution: West of Alamos, Sonora, Mexico.
- Mammillaria swinglei (Britton & Rose) Boed.: (Mammillaria grahamii subs. sheldonii) has wide funnelform purplish pink flowers up to 3. Stile style pink, twice as long as the pink filaments; stigma-lobes 8, linear, pointed, green.

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. Don't add limestone to the potting mix, which must be moderately acidic. It can be sensitive to frost (but some population are resistant to -10° 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.
Propagation: Seeds or offsets.
- Apache, Pima, Chiricahua & Mescaleros: They used the fresh and dried fruit primarily for children, as a snack food..
- Pima: They used the boiled plant placed warm in the ear for earaches and suppurating ears.
- Seri And Pima also used it in special ceremonies by shamans. Fruits are also said to produce hallucinatory effects.
