[dirtbiketina]

I recieved this plant from a grower in Hawaii and it came labeled as N. sibu x mixta, but it looks nothing like the sibu x mixta I've seen, EP has sent me pic of their plants. i did look it up in the data and it looks just like N. eymae x vent x sibu? let me know what you guys think? here are two pics of the pitchers.. Thanks guys:

EP's N. sibu x Mixta

N. eymae x vent x mixta from database:

I'm having a hard time seeing the N. sibuyanensis shape, I see more N. ventricosa. The colouration and wider peristome would suggest N. eymae x vent x mixta to me.
