This large woody vine was found flowering at the Bukit Timah Hill area. The flower reminded me of a red sunflower and I was quite awed by its size too...about 6 cm in diameter. It has a rather wide occurence from south China to most of SE Asian rain forest. Throughout its range, it is used medicinally, as in many members of this family which has many unusual alkaloids which are known to be psycho-active.
