This is not a carnivorous plant.
This is slightly premature in a couple ways. I just got some seeds and I'm struck how odd they look when a bit of the skin is peeled off. Notice also the odd gelatinous material associated with the seed, after soaking in water. Interestingly, I have heard the young seedlings of this species compared in appearance with the most famous talking (and singing) carnivorous plant out there (Audrey 2).
I'll send a potted seed (either now, with a nascent root/radicle) or later, after the seedling actually emerges in a few days. I'll do this free, including postage, to the first person who correctly guesses what this is.
In 2-4 weeks, when the seedlings start to emerge, I should have 10+ additional seedlings, for postage or for trade. Details then, and no requests in advance.
These may be tricky/risky to send this time of year, as they are true lowland tropicals.
A couple people out there probably know what these are, based on conversations. I assume they will refrain from guessing.
The seed, with some of the skin peeled off, to expose the convoluted insides...
