indistinct features of the inflorescence preclude any what you can and already have done, i imagine..
better sharp and side-view pictures could help clinch the dx

Thanks, ... Can you show the clear picture of the inflorescence ?

I have identified it as Platostoma hispidum (L.) A.J.Paton syn. Acroecphalus hispidus (L.) Nicholson et Sivadesen (Acrocephalus indicus
Burm. f.)Kuntze) and it is new addition for eflora group.
