La prima traccia che trovo di Mammillaria bachmannii è in un articolo di John Pilbeam:
Da "REVIEWING THE REVIEW" by John Pilbeam:
M. bachmannii Bod. Certainly all the plants I have seen under this name do not resemble the plant photograph or the description in Craig. The latter plant in my collection is flat, globular, solitary (for six years anyway), with about 16 thin, weak dirty-white radials about 4mm. long, 2 porrect centrals, pink with grey tips in youth, grey later, stouter, the lower about 7mm. long the upper 5mm. , flowers deep carmine, fruit carmine hardly protruding beyond the
tubercles, seed brown with end hilum.

bachmannii Presumably named for a Herr Bachmann, details of whom we have not been able to trace. In as much as this species seems to have been described from cultivated plants the name may first have appeared in a nurseryman's list.
