so every time i feel ive learnt enough about cactuses to ID successfully , the next cactus i find seems to be more ambiguous than ever, this is the case again ;

I found this being thrown out and asked if it was for the taking, it was, so i took some cuttings and i'm geurilla farming them.

Its not the common cactus in my area, that always gets me, and its not bridgesii, the one good species ive found in my earea. bbut it does look a bit like torch to me. and it has the little seagull-wings V above the areole . So i thought it was an active species , but: it has no bitter taste to it at all, and a high spine count per areole , so im not sure

Please help,

Thanx so much
