Mammillaria pringley of celsiana?

A plant with 7 heads

Hello Sonja,

I was rather thinking on M. muehlenpfordtii. Celsiana is suppose to be the shorter spined version of muehlenpfordtii. I can see on your plant heads with long and short spines, so celsiana is a name you better forget.

Hello Sonja,
unequivocally a M. muehlenpfordtii. Actually, she still should bloom in the autumn, also like M. geminispina. My plants flowers always in the autumn and not in the spring.
Greetings
Holger
