I remember that my grandma used the young pods Petai jawa to cook Asam soup when I was a kid, I missed the taste so much now. The pods are thin, flat, green and nearly transparent when young, ripening to brown, rattling with many small, flat seeds.
I found a lot of these large bush growing in our parks, on our sea shore... I am not sure if they are the one can be eaten as a vegetable.
Puff-ball shaped flowers made up of pale green petals and lots of creamy white stamens, it looks like a giant mimosa.
