|discussion=<p>North of Mexico, the hairlike radial spines of <i>Mammillaria prolifera</i> provide an instant means of identifying this species, even without reproductive material. The species is diploid and tetraploid in Mexico, tetraploid in Texas, and mostly hexaploid in the Greater Antilles with tetraploids persisting at least on Hispaniola (M. A. T. Johnson 1978). Spine color and strength of spines form the basis of taxonomic distinction in <i>M. prolifera</i> in the broad sense (D. R. Hunt 1987).</p>
