Mammillaria spec. Cuencamè- Durango

That's a nicely spined plant, Sonje.
Both gasseriana and stella-de-tacubaya are reported from Cuencame, and there has been much confusion over the name. Whatever the correct name for this plant, it's lovely. It hasn't developed any central spines yet, maybe as it ages it might - but then these are quite variable.

Were the hell did you find this Sonja? I heard from Chris that he have bought a big guerreronis, that was the second one that I haven't seen. I must be overlooked a lot of plants. Next year more time in the sales area instead of the bar ( I do promisse this every year).

I agree with Chris, much confusion but I think this is a central spineless stella-de tacubaya.

I bought this one from Wiebe Bosma, it was a bargain. He sold Stella-de-Tacubaya too, but they were already gone when I went there.
What is so special about guerreronis? I sowed these, but don't know if I have any left.

I got two Mammillaria schwarzii from Wiebe. Do you have his email adress? He promised to join our forum.
The specialty of guerreronis is that it is difficult to get and more difficult to get it in flower.
