Hi Ralf,
The plant you show is definitely one of the Polyacanthae series, of which the hooked spines species include nunezii, duoformis and rekoi.
I find it quite difficult to be certain about an identification as the hooked spine is quite a variable feature of this Series. It looks quite like a couple of plants that I have which have been named as nunezii, basically because of the lower number of radial spines, compared with rekoi and duoformis. There's not too much to choose about flower colour or shape between them.
However, we know that number of spines, especially when comparing plants in cultivation with those in habitat (from which species were properly described), is also not the most robust of characters.
Maybe some others here might be able to do better!

Thank you very much for your information, Chris. My guess was krasuckae but rekoi is also possible. Now I'll do a more precise look in the Reppenhagen books and hope to identify these species.
I know sometimes is a identify nearly impossible and very difficult. But sometimes the name is more unimportant than the blooms or a pretty grown plant. I do try only to collect named plants but this is not always possible.

Yes, krasuckae is possible as it is, often lumped into rekoi. I have a couple of plants of krasuckae, though their flowers are a bit duller red-brown than on your plant. Here a photo of one of them, ML370 from La Reforma,Tehuantepec, Oaxaca to compare with.

What is it? Rekoi-10

Ha, I've the same plant in my collection. Look here:
Mammillaria krasuckae ML370

Zitat:
their flowers are a bit duller red-brown than on your plant

This fact and the less radial spines confuse me. On my plant are less than 15 radial spines.

description of M. kras(s)uckae in Repenhagen "The Genus Mammillaria"
Zitat:
26-32 radial spines, 2-4 mm long, the upper are shortest, white

I've compare the descriptions of the nunezii-group and found hubertmulleri.

I think this is maybe possible but not 100% alike.

Hi Ralf,

I think you may be on the right line with M.hubertmulleri. This is my plant of Rep 1460 to compare with.

What is it? 455_2810

Thank you for show, Tam. Now I do think hubertmulleri is definitiv be right. The one difference are the stronger spines on my plant. Therefor there is one cause it is an import plant from a nursery of the canary islands and there is more UV-light than in Europe.

Many thanks for your help.

Greetings
Ralf
