First, Tony, you’re right on with bical. *The hybrid we showed before is N. bicalcarata x rafflesiana. *
Tony wrote “Usually when N. bicalcarata is in a hybrid the peristome elongates and projects foward right where the 2 teeth would have been but they are more fused and it is a gradual progression outward. *Those appear fairly distinct.”
Not always. *We see variation from plant to plant within the same grex. *Here is a seedling of N. bical –red x (spectabilis x northiana). *The fangs are almost not visible. *
Where as the siblings of the same cross show differing degrees of “fangs” -these are also N. bical –red x (spectabilis x northiana). * *
Then, for a primary hybrid, the photo below is a close up of one of our N. bical-red x northiana with two “fangs” trying to appear. *
Sometimes the “fangs” on these hybrids do fuse and remind me of the upper neck part of the peristome on N. rafflesiana. *The mother plant or pod parent of the hybrids shown above is N. bicalcarata. *On Joachim’s plant, there is definitely something on the top of the peristome. *Could it be a mislabeled bical hybrid? *May be the N. bicalcarata is the father or pollen parent or even a grandparent - though the leaves look like very much like bical. *From our own trials, it is very easy to have labels mixed up. *We’ve never seen a maxima with any fangs.
