Fimbristylis dichotoma photographed from banks of river Yamuna in Delhi.
Does not match with images at Fact sheet & other images (except yours) at Fimbristylis dichotoma
Appears close to your another post Poaceae, Cyperaceae and Juncaceae Week: Cyperaceae- Fimbristylis for ID from Delhi-GS75, identified as Fimbristylis bisumbellata
Not Fimbristylis dichotoma, need a specimen to confirm the identity.

ID Request 210411SP03: Clicked at Yeoor hill, SGNP 
may be species of Cyperus but not C. rotundus 
I found it too small for C. rotundus. It is hardly 6 to 8 cm long
Any possibility of SCIRPUS sp. 
Photos are not clear If Possible please send better photographs. but it looks like a Fimbristylis bissumbilata.
