The single yellow-orange flower looks like a Goetzea elegans flower, but the whole buds seems to be belong to Tabenaemontana.
No leaves or other part of Goetzea seen in the picture. Is it possible that a single flower of goetzea fell over and get stuck on Tabernaemontana bud's clump?

Good eye, I thought those leaves were part of a vine with that flower. But this was shot after a thunderstorm so that flower could have come from above. I was confused why the buds were white and the flower orange.

Post thunderstorm scenery.
That would explains why the petals seems firm and fresh along with water droplets.
