Mammillaria prolifera (Mill.) Haw.

국표에는 없다.

Origin and Habitat: The species occurs very widely from Mexico (Coahuila, Nuevo León, Querétaro, San Luis Potosí and Tamaulipas), the USA (Texas), Cuba, the Dominican Republic, and Haiti. The typical subspecies prolifera occurs throughout much of the Caribbean.
Altitude range: It is found at elevations of 400 to 2,250 metres above sea level.
Habitat and Ecology: The species grows in submontane scrub. In Texas, it occurs in grasslands at low elevations and in Cuba, the plant grows in low, dry thicket. Mammillaria prolifera is quite inconspicuous but has a very large extent of occurrence and is abundant. Although there are threats in places (habitat destruction through logging), they are not sufficient to warrant any concern.
