Do you mean Caryocar brasiliense? It's definitely not that.

Yeah, it would help a lot to know if it's a tree or vine.

If you only got the seeds though, it would also help to know the size of the seeds

Medium-small tree. I thought that I had photos of the leaves as well, but I can't find them now.

I haven't eaten it, but my friend says that it tastes savoury and funky almost like durian.

That was my guess too, called jenipapo where I'm from. So perhaps something in a nearby clade.

Similar, but the fruit is green when ripe, and the pulp is always that bright orange colour, and Genipa americana wouldn't be growing wild where my friend lives, and even if it were, it would be a big tree.

Possible, but Garcinia fruits usually have distinct segments, which this doesn't. I'm not familiar with other Clusiaceae, but I doubt that they would have the funk. Someone in the other thread suggested that it could be a Leonia species, which seems likely. I'm not so sure which one though.

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.

Definitely not a Passiflora; this grows on a tree, and the seeds are too large, and the fruit in the photo is ripe.

I just planted the seeds in nursery soil a few days ago. It will be years before I taste the fruit.
