Look it up.
Echinopsis is in the trichocereae tribe, cereus is in the cereae tribe. No hybrids exist..
Grafting does not make hybrids...
Echinopsis does a lot of hybrids with relatives(or plants that are now under echinopsis), among the lines of echinopsis x trichocereus, x lobivia, x cleistocactus, x matucana, x oreocereus etc...

The other parent looks like a Cereus and as far as I'm concerned that's what it is.

The seed which resulted from the cross had two which germinated, one was not viable in the long run, the other is what I have posted.

Think you may find this link of interest, https://www.bbc.co.uk/programm... and in particular the Multiple Genes episode, interesting.

The whole series is particularly interesting as far as I am concerned.

Cheers
