Loxanthocereus/Echinopsis

[D^L]

Hi all,
Perhaps I am going mad but I am interested in a name.:-)
I recall that there was a mixed collection of plants by Ostolaza, perhaps #94941. This was declared as Loxanthocereus sextonianus. But, in addition to this, there was, in the collection, some Echinopsis - largely indistinguishable from the Loxanthocereus out of flower. So can anyone confirm that I have this story right? And can anyone put a species name to the Echinopsis?
Many thanks

I've not heard the story, but it seems a little improbable as Loxanthocereus sextonianus grows like a string of sausages, so to speak, and Echinopsis don't.

Thanks Ralph, I have been confused.
Some Loxanthocereus sextonianus forms are quite long, it's very variable. But I checked the flower which drove me to Haageocereus and thence evidence suggests H. decumbens.

Yes, other than Lobivia tegeleriana, I can't think of anything echinopsis-ish that comes from the same part of Peru.

Sausages or not? These two came from the same packet of Succseed seed

Thanks chaps for pointing out some of these are sausaged than others!

I had a Rebutia grow in a similar 'sausaged' way and I really liked the branching pattern.
Anyway, I think it came with mites deep in the growth tip that
you could not see and were somewhat protected from contact mitocides!
The pests would damage or kill the original growth point each year in the later summer.
The plant would branch out a shoot or recover the tip in spring.
So you end up with the pattern you've seen in one of these plants. Sausaging is recovery
from partial damage and branching happens when a new tip takes over from a dead one.

I hope it is not that, but it might be worth checking!
