Mammillaria celsiana
There is so much doubt surrounding the correct application of this name, that has been dismissed by all authorities on this genus as a dubious and confused name.
Plants seen in cultivation so labelled are usually referable to M.muehlenpfordtii, or occasionally to M.dixanthocentron.
