Purchased a N. Bicalcarata from Fauzi's stall today. I basically like the distinctive feature of the "twin fangs" like thorns just beneath the lid of the pitcher. Also known as "Fanged Pitcher Plant", it was first described by Sir Joseph Dalton Hooker. This species represented the largest foliages ever produced by a nepenthes. That is the least of my concern, as I am more worried about whether I would be able to maintain and grow it first!
