I don’t think it’s subinermis because the spines are very different. Even the guys with long spines don’t look like that. They look more like Myrtillocactus geometrizans spines, but the cactus resembles Stenocereus pruinosus. By the looks of the cactus it seems to be itty bitty so I think it’s just a guessing game for now, and too small to write the id tag in permanent marker.

- not the first. They are always stubby and thick. This ones are surprisingly sharp. Also, ive not seen one have a deeper red tint.

-not the latter either. I suspected that one as well, so I looked extensively at "stressed stenocereus seedlings". Some cut close, but were not like this one. Their spines are the upside down version of what im seeing here. Their ribs were still more plump. And, i have looked at seedlings their age, and size. There was even one from stenocereus queretaroensis on the tray.

I was going to ask if the spines were hard.

The way they are flattened out and stiff make me think of Echinopsis subdenudata, but not feeling that id either.

How big is the little pot it’s in?

its one of those 4,2 cm pots(or so im told thats how they are called). Basically the smallest for wholesale. So, yes, ive seen s.pruinosus in similar pots. Close, but not close enough.

The reason why i stated e.subinermis is that the regular form can have 5 ribs according to llifle.

There was another one of these , and in the same tray, and it had 7 ribs i think...

The other i mentioned looked a lot like this : https://www.naturalista.mx/observations/10615148

I think I may have figured it out, have zero clue why I didn’t think of this to start with. Anyways, I was looking at my Cereus repandus and the new growth’s spines look very similar.
