Which one is the correct ID ?? 
Dictyospermum scaberrimum (Blume) H. Hara
Rhopalephora scaberrima (Blume) Faden
Dictyospermum scaberrimum (Blume) C.V.Morton ex Panigrahi
Dictyospermum scaberrimum (Blume) J.K. Morton

Rhopalephora scaberrima (Blume) Faden is the correct one. Between, if you have access to the plants, please see the seeds, is it brown or white? 

The location being at the same area could it also be Aneilema sessile ??

Please help me to identify this grass.

Why do you feel this is a Poaceae member? I think it is a Commelinaceae member…

Thus is not Poaceae, Poaceae never have flowers like this
The floral anatomy of Poaceae is completely different from other plant members just like an Asteraceae.

I am reattaching the pics. Please help me to identify this commelinaceae sp.

This is Rhopalephora, perhaps not scaberrima. Please keep eyes on fruits, it must be sessile. We have proposed a species in Rhopalephora (=Aneilema) as A. sessile.
It is in press, I strongly believe this belongs to A. sessile.

Enclosing fruiting and seed images as you have suggested.
8 very high res. images.

Yes, it is Aneilema sessile!
