The second

Another mamm.
I don't know if is better to post in the same place different Mammillaria, to avoid mistakes I write here.This could be Mammillaria miegiana?

It is very well spined, I suspect it likes the sunnier climate where you are compared to our duller northern skies. But yes, I think you are right and it is miegeana, Lucio.

Yes, it is always easier to have a new thread for each plant requiring identification, it makes it easier to search for later.

Hi Lucio,

I would have to agreed with Chris and for comparison I give you M.miegeana Lau 1545, not has nicely spined has yours.
