These images were all taken at the same location in Tungareshwar WLS. The first image was taken in December, and all the others at the end of monsoon in 2018 and 2017.
I have identified it as Platostoma hispidum (L.) A.J.Paton, syn. Acrocephalus hispidus (L.)
Please validate.

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.
