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.
I just planted the seeds in nursery soil a few days ago. It will be years before I taste the fruit.
Oh then good luck and I'm looking forward to see them in a couple of years :-)
