Spermacoceae? Pl. check the spelling.

Guess so  but could not close in to the correct ID.

It could even be a species of Borreria. But I am not able to arrive at any ID

Yes, Both same but could not close in into the correct ID!

Richardia scabra L.

A little white flower from Myanmar : 6 posts by 3 authors. 2 images.
I try to determine this plant without success!
I am intrigued by the bell flower with 6 petals welded.
Pictures taken on 24-10-2016, altitude 900met., in Loikaw, State of Kayah, Myanmar

Seems Spermacoce articularis

Thank you for the answer!
The Spermacoce are part of the Rubiaceae which have flowers with 4 or 5 petals, to my knowledge never 6 petals.

I return to your proposal of Spermacoce articularis.
Many points recall this plant: shapes and arrangement of leaves, flowers in evasive tubes … But why a corole with 6 lobes?
Do you have an idea?

Pl. also check threads at Spermacoce articularis if any similar observation is found there also.

… this plant must be Richardia scabra, rough Mexican clover OR Florida pusley
