Spotting

Description:

This flower has pink stigmas (I think they are the stigmas, but they could be the anther) that fall to the ground and go everywhere. The tree they were growing on was only about 5 meters tall. I saw a bee flying around the flower for a while which is a sign that the bee pollinates the unknown flower. Please help me ID this amazing flower!

Habitat:

Growing in a secondary rain forest at Singapore American School.
