Trichocereus identification

[prandz]

Hey guys,

 

Was just after some help identifying these two cacti. I believe them both to be pachanoi but am unsure whether they are the PC clone. Any general tips on identifying this clone would be much appreciated as I have a great deal of trouble discerning the difference.

There are definitely similarities to PC. Might very well be one, or offspring of it. The latter would be a lot more variable, which could explain the subtle differences to PC. That said, I would observe this clone over time and see how it develops. There are clones which appear to be PC at first, but eventually turn out normal Trichocereus pachanoi.

Thanks mate much appreciated  

Are the characteristics of a PC only that they have upward facing areoles without the ‘V notches’ above each areole?
