Dregea volubilis ?

Looks similar.  

Fruits look different from images at Dregea volubilis
Pl. check with images at Cosmostigma cordatum or any other similar species.

Also check comparative images at Apocynaceae

To me looks close to images at Cosmostigma cordatum (Poir.) M.R.Almeida 
However I found no distribution of it in Pakistan as per WCSP 
Catalogue of Life confuses the matter by listing it as a syn. of Hemidesmus indicus (L.) R. Br. (with distribution in Pakistan) although it is an altogether different plant as per images and details at Hemidesmus indicus

What was the size of fruit ?
