I was looking at the tendrils on N. bicalcarata and found something that seems rather unique to the plant itself. The tendrils seem to have a small swelling near the bottom half or third towards the pitcher. While most species do have a swelling near the base of the pitcher, it is usually more gradual and lower on the tendril. N. bicalcarata seems to have a more sudden change in girth of the tendril much higher than other Neps. I couldn't find an official description of the plant itself so I am wondering if this trait could be used as a describing factor or if this trait is present in other Neps not in my collection. Not that with the 2 gigantic fangs the plant has it's difficult to ID, but the more the merrier. I'm curious to see what others are seeing on their plants...
