Hy Jurang!

Your plants are the tipe form Mammillaria deherdtiana ssp. deherdtiana

On the interenet are many pictures with these plans but more are incorect identified.

So on mammillarias.net this picture for exemple:

http://www.mammillarias.net/gallery/D/deherdtiana

It say is Mammillaria deherdtiana ssp. deherdtiana but is not is ssp. dodsonii

Why is ssp. dodsonii....?

Radial spine: 20 - 21, the lowest longest, to 20 mm long, needle-like white.

Central spine: 3 - 5 and 10 to 20 mm long with a reddish-brown colour and stronger than the radial, the form is straight or little curving.

The plant look like the plants Wolter photo on the field

And a surprie the same plant on the same site as dodsonii Smile...you see photo Luc and the description

http://www.mammillarias.net/gallery/D/deherdtiana_v_dodsonii

The tipe form is this:

http://www.mammillarias.net/gallery/D/Mammillaria_deherdtiana_DH_1114_91_Am1

Sure ar formes and formes here is a plant like yours:

http://www.mammillarias.net/gallery/D/Mammillaria_deherdtiana_1

More radials and centrals...ssp. Dodsonii haves 20-21 radial and the centrals are evident and little curving

Here is the real dodsonii:

and sure wolter,s photos are great to see dodsonii

All your plans are the same clone?or from seed?...the second photo is very tricky, not all the seed sourses are good, this plants are flowering in the same period and not all the nurserys have do the corect polinizatian...i have a friend who haves hybrids from a good soarce and y don; t give the name.

Regards

Punker
