Mammillaria matudae 'compacticaulis '

The plant in picture I have started from seed about 10 years back, and it developed in modest looking but neat and freely flowering specimen. It is not M. matudae you usually see in cultivation, but a different form, close to what Reppenhagen called M.compacticaulis. This form is somewhat intermediate between M. matudae and M. backenbergiana, both growing in the same general area - southern part of Mexican state Mexico.
