I agree - Notocactus uebelmannianus (syn. Parodia werneri).

There is a yellow flowered form too = N. uebelmannianus v. flaviflorus, which is seldom grown since nurserymen no longer seem to propagate it because the purple flowered one sells better.

When first introduced from the Horst-Uebelmann Expedition there were three species of what were dubbed at the time the "Gymnocalycioide Notocacti" since their bodies looked rather like Gymnocalycium's out of flower. The yellow flowered form of N. uebelmannianus is seldom found now in collections as nurserymen only tend to propagate the more saleable purple flowered one. Also, the other similar species were all lumped under uebelmannianus when it was transferred to Parodia as P. werneri, the name change required because a Parodia uebelmannianus already existed so had priority of that name.

By chance I purchased a tiny seedling a few years ago, supposedly yellow flowering. I knew nothing about the purple/yellow issue. While it hasn't yet flowered, perhaps the size is now right (5 cm).

Yes, it's a pity when certain plants common at first in collections gradually die out in the trade.

Gymnocalycium horstii is a similar example where the pink form = originally ssp. buneckeri or G. buneckeri is now usually just sold as G. hostii and the original type form, the white flowered G. horstii, is hard to find. When supposedly new species get "lumped" they do tend to die out and only the most attractive form under that name commercially propagated.

See my post here for the difference.
