I could make out the genus name definitely started with E and the species name looked like it started with V (or maybe W). It looked like it said villosa.
My thought is E villosa var. laniceps, which has curly spines like this
Not an Eriosyce, it looks like a Mammillaria? A bit like a long spined M. crinita? The flowers will prove it is not an Eriosyce since it is large enough to flower.

That's a 66mm pot (2.5"?). Are you sure that's big enough to flower?

This looks very similar to my Stenocactus lloydii seedlings, so maybe the E stands for Echinofossulocactus?
So possibly labelled as Echinofossulocactus vaupelianus i.e. Stenocactus vaupelianus.
It does have the fine white spines I can see in the pictures. I don't see any photos with wavy central spines however.
I assume in Stenocereus seedlings, they start out tubercle-like and then develop ridges? A but like a smaller version of Ferocactus seedlings?

Yeah the spines seem too long for S. vaupelianus, I just thought the resemblance to my seedlings was uncanny. I have attached a photo so you see what I mean. S. lloydii is also supposed to have almost straight and flat spines when they mature, and my seedlings don't really look like that at all (yet?).

And yes, that seems to be the case for a lot of cacti with ribs, however yours looks like it should be big enough to start to form the ridges, so I really don't know what's going on here. I might also be completely off.
Growing mostly under LED lights, in northern latitudes. Especially interested in stem succulents and caudiciforms. Dreaming of my first greenhouse.

I guess I will be waiting until it gets bigger then.
I do hope it's S lloydii. It's a very cool looking cactus.
Not grown many Stenocactus from seed and that was decades ago, therefore cannot remember if they were tuberculate initially before forming narrow ribs. Anyway a bit more age on the plant will sort the matter out one way or another.
