Notes: There is a lot a confusion about this species, hunt and Anderson consider it a form of Mammillaria perbellaSN|20725]]SN|20707]] which forms dense clumps by dichotomous division, but it is clearly evident from the photos showed in the original description by Craig that they are not exactly the same. The M. cadereytensis is actually considered (Pilbeam) a short spined variant of Mammillaria parkinsoniiSN|20707]]SN|20725]].
