Rain Tree - with a large, symmetrical umbrella-like canopy. You can see them all over South Bangalore lining avenues.
These are the flowers of the rain tree
Once the flowers dry up, they fall, and make a kind of carpet on the floor, like this. You can see them in bunches on the road everywhere right about now.
Those pods you see are the ones from which we used to make cork balls in our childhood. You can also frequently see them on tarred roads, absolutely flattened, with only the seeds protruding from the road.
