I want identification of this flower.
I can not even find the family!
Photos prises le 14-10-2016, altitude 350met; à Hpa-an, Etat Kayin, Myanmar

Looks close to Corydalis sp. (Papaveraceae). Not sure though!
I think it will be Polygala sp. (Polygalaceae)
Close up of flowers and fruits is not clear.
May be a species of Polygala or Salomonia 
It belongs to Polygalaceae, Polygala or Salomonia, details of stamens and a close-up image of fruits will help. 
Excuse me for the delay in answering you for an abscence.
Unfortunately I do not have more precise photos of the fruits and the stamens of this plant.
Thanks again for your cooperation
