I leave you a photo of my mammillaria haageana var. elegans

I hope it helps you
Hi dinfelu,
thanks for the photos. At first sight, my plant is quite different from your chionocephala. A little different from your haageana v. elegans but it could be due to the growth conditions...I cant decide.
thanks for the help, anyway!

All these species are quite variable, which is what makes this a difficult call.

I was totally surprised by this flower. No idea about the species....
It has 3 central spines, short and very robust, and 15 radials.
Any suggestions?
Thanks a lot!

Mammillaria dodsonii or M. deherdtiana? The spination varies and yours looks strongly spined?

Thank you Dave, yes, it can indeed be one of the two. Reading the description (by John Pilbean), the subsp. dodsonii has purple stigmas, while subsp. dehertiana has white stigmas, which is the case of my plant. Spines description of dodsonii is more similar to my plant, but as (I believe that) spines vary much more than stigmas color within a given species, I tend to identify my plant as M. dehertiana subsp dehertiana. Even if spines are different. Moreover, apart of M. dehertiana (and its subspecies), what could it be? With such a flower like that, there are not to many possibilities. Thank you.

More pictures of the plant #0232 (already posted here).

All in the plant says M. zeilmanniana. Except (as far as I noticed in the internet) the rounded petals.

Maybe someone has a different perception now.

Pictures of two big flowered Mammillarias.

The first one has been posted here already and it was suggested to be M. deherdtiana. The flowers match but spination definitely not, so I am not satisfied. Someone (out of the forum) suggested me M. melanocentra var. rubrograndis. Reading the Pillbeans' guide to Mammillarias I agree that it can be rubrograndis but pictures in the internet of this species looks very different. So I have no clue. Maybe someone that have a rubrograndis and/or a deherdtiana could tell me something. I imagine that with such a big flower it will not be difficult to identify.
deherdtiana or rubrograndis?

The other plant I would like to ask for help could be M. melanocentra subs melanocentra (below). Description matches but again, pictures in the internet do not..

A closet look into the spines of the putative deherdtiana/rubrograndis of the previous post:

I'd say this is rather M. rubrograndis. Mammillaria deherdtiana has numerous (33 - 36) fine, curved towards the body radial spines, centrals are not always present.
All in the plant says M. zeilmanniana. Except (as far as I noticed in the internet) the rounded petals.
Some plants may have more rounded petals then others. Even the seedlings from the same batch.

Thank you George. Thanks for the pictures of different M.zeilmannianas, very didactic.
I believe the thread is confusing with many different plants in the same ID request so I will post them in separated threads.

I'd say this is rather M. rubrograndis" M. dehertiana holds seeds inside the plant body so if you get fruit popping out its not dehertiana

That's the plant n. 403, in bloom today." Also maybe M. perbella ?

Thanks Lucy and Keith. I'll search for these names and read their description to see if it matches.
I'll stop this thread with multiple plants...it does not work fine because is dificult to refer to a given plant. I'll separate those that are yet to be identified in different threads. Sorry for that!
