copiapoa...NOT!

[Jangaudi]

I bought this cactus a couple of years back, in a bulk sale from a local hobbyist, who wasn't sure what it was. My first reaction was....Copiapoa ! maybe a young dealbata. Later on it took some damage due to poor ventilation I think, but kept growing nicely. And now it's sending up floral tubes from the areoles ! So that's that, probably something else...maybe one of the Eriosyces ? But I couldn't find a match really. Even the plant id apps give Copiapoa as a result
Any wild guesses before the flowers open up ?
Thx

Acanthocalycium glaucum

Acanthocalycium glaucum

Hmm, considering the variations in the species I guess it could match, though a lot of features are different from the regular Acanthocalycium glaucum, with the blue-ish skin and the yellow flowers....Anyway, here's the first flower....still not convinced though...the petal count seems a bit low, and the bright green color inside the flower reminds of Echinocereus flowers. Also the stigma sticking out above the anthers..and it seems to be curled up, and rather long..let's see how it looks tomorrow
Thx so far !

Looks like a Neoporteria flower,
and since it's reddish, it could be Neoporteria carneoflora

after googling the name, it doesn't come up for some reason
I have 3 N. carneofloras, with flowers identical, but the spines are shorter

I think we can be confident it's a Neopotreria / Eriosyce, as I placed it beside the blooming crispa. It's indeed hard to find pictures of Neoporteria carneoflora, but it seems a subspecies of N. odieri which looks more different than some other species I came across, like N. curvispina or N. setosiflora or even a different variation of the N. crispa...anyway, this is gonna be a hard nut to crack. What I will do is let it grow a bit to its normal condition again, given the battered state it is in now, and then maybe later it might become clearer. Thx !

Here is photo of my N. carneoflora
Probably a green bodied form of N. napina
Much shorter spines than your plant

This page from Cactiguide has all kinds of pretty Neoporterias

As I recall Backleberg's invalidly published Neochilenia carneoflora has not been found in the wild again but was grown by Killian from a batch of collected seed of another species (glabrescens?), therefore basically a pink flowered selected clone. Kattermann reduces it to synonymy under Eriosyce odieri subsp, glabrescens. However as you can see Ferryman reduced glabrescens to a subspecies of napina.

Flower colour in the Thelocephala group of Eriosyce can be variable in habitat but when sent to Europe were often given different species names. Backeberg was also a "splitter" rather than a "lumper".
