@Vijayasankarji I was merely responding to the description that it was globose fruits "What surprised me was that the tree had spherical fruits (dried ones) hanging like grapes. Kindly have a look at enclosed photographs. Could this be due to some disease??" by Prasanth If you refer to [efloraofindia:27751] Pongamia pinnata the conversion of reproductive parts into galls is a little more clearer though not as clear as for Id. here we can see half the flower cluster has set pods. In the present case unless I can feel it it could be dried flower buds too for which Prasanth may have a better idea. Leaf galls by the eriophid mite are very distinct and are more prevalent than the woody galls.
