Mayur Nandikar suggested me that it could be Spathodia campanulata or
Kigellia pinnata both Belongs to Bignoniaceae Famous one for Showy,
large flowers and these two are planted as avenue tree for its
beautiful flowers.
It quite looks like Spathodia campanulata or African Tulip Tree.
Searched on the net and found an interesting image -

In the given link a parrot is eating the winged seeds from the open
pod of the African Tulip Tree. The open pod looks very much like the
pods in the picture DSCN0470c.
Thanks Mayur ji.
