Bungong Uteun (Wild flower)

Nature always gives the best for us but we do not know much about it. I found this flower in the grass. I have tried to search from some sources on the internet but I have not been able to find the scientific name of this flower. in everyday we call him with the local language of Aceh is "Bungong uteun".
