My turn to take a guess. :-). I agree with Wire Man: It's definitely a S. psittacina hybrid. The psitt hybrid with S. flava does look very different, but the hoods don't always open. I have two different clones of the same hybrid, and the pitchers vary on the same plant in the same season. See below:
I don't know the complex psittacina cultivars very well, so it could certainly be one of those. To me, however, it looks very much like an S. alata x psittacina hybrid I have:
And by way of comparison, below are hybrids of psittacina crossed with two different rubra subspecies. S. rubra wherryi:
and S. rubra gulfensis:
This last one (one of my favorites) is a recently-named cultivar: S. 'Gorey'.
Hope this helps!
