EDIT: This is the fruit from a Leichhardt Tree, edible but very bitter. See below for the original question and subsequent discussion. Hi all, I found a couple of trees on the way home today that were dropping an unusual looking fruit on the ground. I picked up a couple but I'm having no luck trying to identify them online. Does anyone know what the name of the fruit/tree is, and whether they are edible? They smell quite a lot like gum nuts and one has started rotting and has a whiff of banana so I'm quite intrigued! Any ideas? The one in these photos is about the size of a large kiwi fruit.
