Cacti I.D. please!

[thoughts]

Hey folks, I have two queries one is a cactus growing in the ground down the road from where I live and I would love to know what species it is. 

 

The other is a cactus gifted to me by a friend who picked it up at the SAB nursery. It's an impressive looking thing and I'm wondering might it be a cuzcoensis? It is labelled "Echinopsis sp. SABO22"

 

Let me know if any more pictures are needed. Your thoughts are much appreciated :-)

Hi thoughts, welcome aboard.

First one in the ground is a cereus, not sure which one exactly, maybe jamacaru?

Second one has that Cuzco look about it. The central spines on Cuzco usually flare out in a conical shape where they emerge from the areole.

Thanks Glaukus. Yeah I'm a bit lost when it comes to finding a definitive way to I.D a cuz. Very tricky...

 

Anyone else have any ides re. the second cactus?

Based on spines and the wavy shape down the ribs, the second cactus is also a Cuzco, I reckon. When it grows bigger, the spines at the bottom should start to turn very white. If that doesn't happen, I would guess it's a cuzco/peruvianus hybrid.
