Eleocharis congesta D.Don ???

Looks alike but the spikelet not matching...
Pl. check with Eriocaulon species

Thank you ...! Close to Eriocaulon cinereum R.Br.  
Eriocaulon species are very confusing.
What are the species reported from your area?
You have check with details at GBIF, Checklist of Nepal, Flora of China, FoC illustration, POWO etc.
Thank You …! I found it in a semi-aquatic habitat. The inflorescence heads are black and the leaf 4-6mm wide, has 3 distinct midribs. It might need further observation.
I just want you to eliminate other species found in your area.
Other possible species in Kathmandu valley are  
1) Eriocaulon nepalense J.D.Prescott ex Bong. 
2) Eriocaulon nepalense var. luzulifolium (Mart.) Praj. & J.Parn. 
3) Eriocaulon staintonii Satake

On checking in GBIF, I found two specimens of Eriocaulon nepalense J.D.Prescott ex Bong. (one of them having the earlier name of Eriocaulon staintonii Satake). Pl. see 
https://api.gbif.org/v1/image/unsafe/https%3A%2F%2Fpictures.bgbm.org%2Fdigilib%2FScaler%2FIIIF%2FB!10!00!86!99!B_10_0086999.jpg%2Ffull%2F2048%2C%2F0%2Fdefault.jpg
For Eriocaulon staintonii Satake, GBIF does not have any specimen.
Also GBIF does not show any specimen of Eriocaulon cinereum R.Br. However, there are many specimens from India. Two of them given below:
From the above, I am also leaning more towards Eriocaulon cinereum R.Br. as a layman.
Pl. have a look again.
