Mammillaria schwarzii fma. roseiflora?

Hello everyone,

I wanted to show of two of my Mam. schwarzii's I bought last year, they a flowering currently. Surprisingly one of them turned out to have pinkish flowers.. Are these plants maybe hybrids?

Regards Jonathan

I would think that all the plants shown in this thread are hybrids. If you don't prevent pollinating insects from entering into your collection, you will get hybridization, especially in a collection of many mammillarias.
I once had one M. zublerae (gift from a friend in England) and found fruits on it about 10 years ago. M. zublerae is not self-fertile and the plants which came from this seed were a real mix. I posted the photos in the past and recently I took photos of the plants from the next generation. I will post them in my old 'zublerae hybrids' subject, so you can see how variable these hybrids are (probably hybrids with carmenae and laui which stood nearby that single zublerae).
Nowadays, pollinating insects cannot enter my greenhouses anymore and this zublerae has never produced fruits since then.

Thank you for your opinion Wolter, I knew you would know and thank aswell for the pictures. My plants came from an italian seller. Since this year I have an insect net against cross-pollination. But I think not only the italians but many sellers that dont take care of this sell hybrids and sometimes you cant even tell..

The plant of Vladimir is not hybrid in my opinion, I think the label says Mam. erytrosperma what it certainly is.

Kind regards Jonathan
