N. jacquelineae x izumiae
Pat.. that is just one of many. *There is a fair amount of variation in coloring both on the pitcher and on the peristome. *With a few having some stripes on the peristome also. *Pitcher on the dark red one is about 4" tall. *The peristome details seem to be getting more pronounced still as they get larger.
Here is my other favorite clone. *Color is a tad off.. it's a bit more orange than it looks. *This pitcher is about 5" on a 10" diameter plant.
