My latest addition

Could I please have an ID on this one, please? I have an idea but not sure...thanks!

I would go with Mammillaria brauneana.

Very nice addition indeed

Yes, Jonathan is correct. The plant is a syn. of m. klissingiana.

Aaah, that didn’t occur to me...are there spine colour variations? I have one but with white spines, not black.....

It's a gemstone, for sure...

I must admit that I am unhappy about M. brauneana should be a synonym of M.klissingiana. I know that this is probably heresy, but to me it looks closer to forms of M. formosa. Hunt condemned brauneana to synonomy because of geography, whilst saying that wild populations had not been found. That was in 1977, so somewhat outdated, and there are plants that have been found in Tamaulipas that look not unlike the plant shown above. If you look at klissingiana the typical form has both wool and axillary hairs, and all spines are white. Its tubercles are quite narrow too. M. brauneana just doesn't fit in my opinion.

So this is my doubt....I have this plant labelled as M.Klissingiana yet I fail to see any resemblance....?

I would be inclined to call that m. geminispina subsp. leucocentra.

This is my Mammillaria SP     ROG 326
affinis formosa . Cerritos - SLP

Mh……….. mumble, mumble

I’m awfully confused now....
