I have several ripe berries of both Nephthytis afzelii and N. poissonii (which I think is the most beautiful species with its deeply sagittate leaves) which I would be happy to swap. They make fantastic house plants, really tough and happy in low light. Germination is slow but in my experience 100%. I also have a couple of small plants available of N. poissonii.
I am looking for fresh berries of Anthurium bakeri (impossible to get in the UK) or other small Anthuriums/aroids (I don't have room for the bird's nest species sadly) and especially if anyone has seeds/cuttings of the non-aroid Cyanastrum. Also (a very long shot...) Psychotria ankasensis, an amazing metallic-leaved species.
