Here's a plant which I don't know the ID of. It definitely has alata in there, you can really see it when it's viewed from the front. I originally thought it could have oreophila in there as well as it is SOOO vigorous. It pitchers non stop all season, but doesn't grow oreo style phyllodia.
It's flowers are pale yellow - not alata pale, but not as yellow as flava/oreophila.
