Hello. I have got really nice mammillarias and i wonder what species they could be. There were several plants in each of the pots and i don't know if they are all the same species or different varieties/subspecies. Could you help me with identification?

1.
3 mammillarias Ph7sEr5 3 mammillarias B5fkY39 3 mammillarias 0TeTusP 3 mammillarias F6LV2lL 3 mammillarias UCjoSP2
So maybe check first the number of central spines: the smallest head, nr. 1 has 5. Nr. 2 and nr. 4 has 2 centrals and nr. 3 has 4.
Radial spines: Nr. 1 has about 20 radials, nr. 2 - 15, nr. 3 - 18, nr. 4 has just 10
Colour of spines: numbers 1 and 2 have much brighter spines than 3 and 4. Maybe just becauce of age of the heads?

2. Some mamm. of polythele group?

Some heads are almost spineless but some have 0-1 centrals and 1-5 radial spines.


3. Mamm. backebergiana?
3 mammillarias QV4C1Fx  3 mammillarias QD1Hvll 3 mammillarias BRSGI0D 3 mammillarias IjkDo5K
Central spines: nr. 1 - 1-2, nr. 2 and nr. 3 - 2 central spines
Radial spines: every head has 10-12 radial but head nr. 2 has darker all spines

Hi Arash,
I believe no 1 plants are most likely m. spinosissima, possibly sub. pilcayensis.
No. 2 again most likely m. polythele f. nuda.
No.3 looks ok for m. backebergiana.

Thank you for your help. Smile Mammillaria polythele it's the same plant as Mammillaria polythele cv. Stachellos?

Have 3 more plants to ID.
1. The first one is also M. polythele f. nuda?

Yes to photo 1, polythele nuda also, its variable.
Secondly yes, M. elongata to both. Sometimes the form with the central spine is called echinaria, but really its nothing as significant as a different species, or even subspecies, imho. Though some people would give it such rankings. Depends on whether you focus on similarities or differences.
