Rio and macro traits imo. I have lots of different looking plants to the point I give away based on looks.. and this look is my favorite that I always keep. I have rio, macro, cordo, that all share similar spine and areole traits. The lumpy/bumpy ribs, a big reason people identify pc sawtooth as a rio characteristic.. the thin short spines out of such pretty white areoles.. looks like multiple macro I have ( including Chavin op seed grown) and if it had a more scop rib profile, the spines and areoles would also look very similar to a special cordo clone of mine. Again just my opinion obviously.. but seriously I would trade you named clone if you want to be sure. I suggest you hang into it and care for it though. But also get some pc anyways… it’s not fun making mistakes and learning on plants more sensitive and expensive than pc.

And also as people have said, if it’s seed grown as this looks to be, it cannot be pc anyways. I have multiple pc hybrids, but like any other clone, nobody has seeds for it ( except something like gf, which can be gfxgf cause it’s a seed group not a single clone)
