Well, just about a year later and the ol' N. X Aeneas N. [(campotiana X maxima) X ('Ile de France')] is flowering again. I'm not particular of what females to use the pollen on. . . whatever is available in the flowering market currently is fine by me (50/50 seed split). I'd say the flower has about several weeks before it opens.
Here are some pictures of the intermediate pitchers from one year ago:
And the latest upper pitcher, as of yesterday:
Just a little FYI, due to my past experience with my pollination efforts of this hybrid I want to make clear that there doesn't have to be full pollination of all the pods on the stalk with this pollen. In other words, make sure you (the female nepenthes owner) have some left over pods to exploit other types of pollen on. The chromosome numbers could go either way for such a complex hybrid like this, but the results could be rewarding.
