Please ID this small tree with white flowers. Photo was taken in Sri Lanka in Nov 2011.

cant really make out the details of the flowers

Appears to be some Jasminum species.
I could not find a match as per comparative images at Jasminum

The reproductive whorl is androgynophore. They form single unit, if so it may not be Jasminum. I think more characters are required to come to a conclusion.
I haven’t come across this plant yet.

Appears to be Gardenia sp.

Pl check for Gardenia taitensis.
