Indian tree (Polyalthia longifolia) seeds are often found, dropped by birds (and bats, maybe) all over the city. I've always wondered what the fruit is like-- obviously, flying creatures love it.
I found a half-eaten fruit recently. It actually tastes like a very paltry date. Not to sweet, pretty delicious. (Note: I didn't eat a lot of it, so I don't know if there are adverse reactions involved.)
