It looks like Fimbristylis littoralis Gaudich. But a specimen of the plant has to be checked to confirm the identity.
I have doubt about the identity of this plant. There is a closely related species Fimbristylis umbellaris (Lam.) Vahl
So it is better to confirm the identity at the Central National Herbarium, Howrah by matching the specimens.
Thanks to … again, As far as I can remember, and also can be guessed by the attached picture, the culm is four angled and since it was found beside fresh-water (pond) this is possibly either Fimbristylis quinquangularis (Vahl) Kunth or F miliacea (L.) Vahl or both!
But, I do not rule out F. littoralis as well.
here is the picture. Attachments (1).
This looks like F. miliacea (L.) Vahl, as in http://plants.minibird.jp/hydrophytes/plants/shissei/ha_gyou/hideriko/hideriko.html
