Millettia peguensis/ovalifolia or Moulmein Rosewood as it is called is native to Lower Burma and Siam. This is a relatively rare tree as compared to Pongam that is very similar looking, but more common in India. Pongam has white flowers while the Milletia flowers are bright pink. Pongam has more elongated tip to leaves, while this is more oval. Will try and upload complete tree and leaf images to make it easier to distinguish. This was shot in Cubbon Park.
