Echinocereus ID?

[Ava]

I sowed several species to a pot and relied on placement to remind me which was which, but now all the seedlings are bigger and have been repotted a few times (and some seeds clearly ended up in different areas of the pot than they were meant to initially) I have some of them mixed up :/ This should be either Echinocereus reichenbachii perbellus, E. fendleri rectispinus or E. palmeri - can anyone help? From a few pictures E. fendleri looks the most likely but still not quite right (the very long spines at the top in particular). It's around 5 years old.

Tip: if you insist on potting multiple species per pot, then make sure they can't be confused (at least, when older). E.g. put no more than one species of each genus in the mixed pot.

That's a good idea, I'll bear it in mind. This year I'm trying to find room for a pot of each species. Suppose I was just thinking they would like similar growing conditions.

Of the 3 species you list, it looks to be fendleri rectispinus.

At that age and size it is almost impossible to tell, wait two years and it will be obvious, now you know label everything, most ( not all ) cacti seedlings look the same for quite a while.

Thanks!

Well, they were labeled, just not adequately. Perhaps I'm lucky in that my seedlings all do look very different. Neither of the remaining 2 Echinocereus actually germinated/survived.

I agree with Mike.
Of the plants you name only E.fendleri v.rectispinus would have spines that long.
