Wild Flowers wait for answers.

It's easy to find these wildflowers again for those of us who live in the countryside or around the humid forests, especially in Sumatra and Southeast Asia. This wildflower I found around my village. I have searched from several sources on the internet I have not found the real name of this wildflower, maybe I am less thorough in searching but I do not want to guess it because I am not a researcher. Hopefully there is someone who can help give the scientific name of this flower.
