Any ideas...?

I bought this plant at a supermarket and I would love to have a name to put to it. It's in a 7cm pot and, as far as I can tell, it hasn't attained its full girth yet. Radial count at about 25-30, centrals mostly 2, up to 4. Wooly axils and areoles and perhaps a few bristles on young axils, but not sure about this. As much as I love to browse through text books searching for a description that fits a given plant (an old habit I got from reading Borg's Cacti back to back), this one still eludes me. It has something of M. haageana and something of M. parkinsonii (minus the flower colour), and yet...

Any help welcome, thank you.

i think that could be m.albata
mammillaria albata is referred to m.geminispina ssp. leucocentra
look at the picture of m.albata from s.vincente....

It certainly looks like a good match. I looked at your pictures of M. albata, but I guess I didn't scroll that much down.

Thanks, Maurillio.

eu nau entendi o que quer dizer con "but I guess I didn't scroll that much down".
me diga, por favor, donde esta planta è diferente da sua.....
so entao poderemos enfrentar!

I only looked at the first two or three pictures and then moved back, I did not look at all the pictures.

The plant from San Vicente is a better match to my plant than these photos. My plant seems to have larger tubercles and the central spines are darker at "birth" and keep the tips dark for longer. These are unimportant differences, the plant feels right for the species, up to the position and tone of the flowers.

i completely agree with you.
i hope thet we can have other suggestions....

Hi all,
I was away yesterday and didn't see this until now. My first thought also was M. albata, but I also thought about M. hahniana ssp mendeliana, but decided that the radial spination was not right, so again came back to M. albata. This is, as Maurillio says, now considered to be a form of M. geminispina. This species is quite variable, and we know that spine strength can vary a lot anyway. So I think you have it right.

Thank you, both. I wouldn't normally bother you for an ID, but this is a plant I am particularly fond of.
