I recently received seeds of a strange funky fruit from a friend in the Amazon. We have no idea what it is, and Jim West can't tell from the photos that my friend sent to him either. There was a delay in getting the seeds here, but I stuck them in some soil two days ago, and they are already starting to sprout, so they seem like survivors!
It's a medium-small tree that fruits in February/March at ~800m elevation in SE Ecuador. If anyone knows what it is, please don't hesitate to comment.
That's an interesting plant, so thanks for sharing. The descriptions and photos don't quite match though. I suspect that it's most likely a Leonia species, but I don't yet know which one.
