bridgesii; cuzcoensis; fulvinanus; pachanoi; peruvianus; macrogonus; taquimbalensis; terscheckii; validus; werdermannianus??

 

only one way to find out... cut that mother fucker111

 

1 is the only one of those that looks remotely like t. Pachanoi and I can't tell for sure but I don't think it is.

 

Never studied or used san p. myself, but those don't look like it from the pictures I've casually come upon.

But the tall one that you fit all of in the picture frame looks badass, especially the tallest part.

 

2,3,and 4 are not alkaline bearing, although called "trichocereas cacti". Pic 1 is amiguously dark and distant, but not San Pedro...

 

spines are too big and the ribbing too deep.
