5. Mammillaria spinosissima?


6. Mammillaria Sempervivi?



thank you again for your support

Good morning Nuxtofulakas.
Number 4 looks like Mammillaria bocasana ssp. bocasana .
Long ago, I bought the same plant as the Mammillaria bocasana ssp. bocasana "multilanata", but I'm not sure of the "multilanata". good research.

No 1. Yes
No 2. Could be M.karwinskiana.
No 3. Hard to say from an above shot.
No 4. Yes
No 5. Probaby

i thik that
1 could be a cultivar called marnier-lapostollei or delapostolle
2 m. karwinskiana
4 m.bocasana
5 m.spinosissima
6 m.sempervivi

these are two extra photos for number 3 - to help identify it.
Hope this angle is ok...

any news regarding number 3?
thank you!
