One of the best crosses made in the last decade. The pitchers take on purple coloration with a unique orangeish fade to the peristome when they hit maturity. The teeth are very well developed and distinct.
This specific grex is made using Nepenthes robcantleyi as the female parent and the Tambusisi form of Nepenthes hamata as the male. This hamata is renown for having the most elongated teeth and darkest pitcher coloring when young so it's likely transfer into these offspring and that would make an already excellent cross even more outstanding.
