This is from a bunch of cuttings that I got last summer. I thought that I had them right and that this pot was a couple of ventricosas until the ventratas started pitchering. Just as I was convincing myself that it is a ventrata, I see this auction Nepenthes ventricosa...everybody needs one! (Winner Jm82792 $15)
and these pitchers look just like the ones on my plant.
So which is it, and why?
