I think it is a good idea of Andreas, to try to organize a 'partner
treff' for Nepenthes ;-) ; I think there are a lot of Nepenthes-
flowers unused, because a male or female plant is lacking at this
time.
Maybe it is possible, to conservate pollen by freezing; e.g. I have
the possibility to freeze-dry flowers and Andreas can store it
in liquid nitrogen.
I would be interested, which female plants of Nepenthes are in
cultivation.
At my plants, I know, that the following are females:
N. bongso
N. ventricosa spotted
N. maxima green (Celebes)
N. dubia x gymnamphora
N. spathulata (label, never flowered at me)
Cheers
