Possibly Harrisia and Eulychnia?

Found both of these for sale while taking a long drive from where I live and normally shop. The first was this old timer's farm where he and his wife were selling loads of things. The second was at this little open-air cactus and succulent place about one town over.

Harrisia perhaps:







This looks like a Eulychnia to me. It has the lumps the seedlings have, and it also have the slightly upwards spines:

Stenocereus of some sort I believe. Thought Eruca at first but the spines are not flat enough.

The second plant looks like Cleistocactus pycnacanthus/morawetzianus.

The irony is I bought a cutting of that yesterday.

It matches both C morawetzianus and Eulychnia to me.

The last is Machaerocereus eruca.

The last is Machaerocereus eruca.

I've taken a look at photos of S eruca and the seedlings don't match.

I am not familiar with any of these, but I was curious about the last plant (neat spines and epidermis texture!) I browsed a bit and your plant looks similar to Echinopsis (Cleistocactus?) buchtienii.

Hopefully the flowers help?
