Help with ID of those plants

[lockheed]

I have some plants to identify. Some harder than others:

1. I have never seen anything like that. It has a tag name, but I think it is either incomplete or wrong, because when I search I find nothing like it.



2. Here, there are two plants, I think. I am asking about the one on the left. It is some monstrous variation, but of what?


3. This one I am drawing a blank on:


4. And the last one:


I'd appreciate some help with those. Thanks!

1: echinopsis lageniformis f monstruosa (clone b/short clone)
2: cereus peruvianus f monstruosa (not a 100% sure)
3: stenocactus?
4: sulcorebutia rauschii

As Snarfie says the first is one of those monstrose "pornographic" Trichocereus. Which species you assign it to is a matter of opinion unless you get a reversion to normal growth:-

Thanks, guys. That would cover all but no 3. What could that be specifically?

Seedlings like 3 can be hard to id as their appearance and spination change a lot as they mature.
I think it's more like an Echinocactus, Ferocactus or Thelocactus - it's got too few ribs to be a Stenocactus.

the number 3 it look like a yung Echinocactus platyacanthus …or not

I hope you have better luck than me rooting the rauschii. I had about 6 offset that size that refused to send out roots they took the best part of 2 years but all eventually dried up.
