Thanks, Pardesi ji.

As per description of Merremia umbellata as per Convolvulaceae Unlimited: 
Inflorescence umbelliform cymes, few to many flowered ....

It further says:
Merremia umbellata can be recognized by its whitish puberulent axial parts, especially the pedicels; the crowded, umbelliform inflorescences (the secondary and tertiary branches short or none); the unequal sepals, with the outer two shorter, obovate, tapering to narrow bases between which the inner sepals are visible. Generally, the flowers of M. umbellata are smaller and there are more of them per inflorescence than in M. bambusetorum and M. kingii, though precise delimitation for these 3 species remains elusive.

It may be Operculina turpethum (L.) Silva Manso, with flowers solitary or cymose as per Flora of Pakistan (also see Flora of China).

Pl. confirm.

I think, you have a wrong notion of Operculina turpethum (L.) Silva Manso, Mr. Garg.

Sir, sorry ! I don't have other image. Stems of Operculina turpethum are often purplish, prominently 2-to4- angled, and narrowly winged.

By now it should be clear that this species can't be Operculina turpethum - NO, NOT FOR THE STEM (though winged stem is an identifying character, but I will leave that part). The CAPSULE/ fruit in Operculina turpethum is "CIRCUMSCISSILE DEHISCENT".

So, what this species can be is the million dollar question!

Is it Merremia umbellata (L.) Hallier f. (of eFI), which is based on  Ipomoea cymosa (Desr.) Roem. & Schult of "Flora of British India"?

There is no easy answer to this very question, because -

1. Merremia umbellata (L.) Hallier f.  is now Camonea umbellata (L.) A.R.Simões & Staples
   
2. Ipomoea cymosa (Desr.) Roem. & Schult  is now Camonea pilosa (Houtt.) A.R.Simões & Staples
   

...... more ???
