It can be Schoenoplectus juncoides, but I need a specimen to confirm the identity.


I think Scirpus lateriflorus..


… may be correct. But I need a specimen to confirm the identity. In Cyperaceae, often image of the plant is not enough for correct identification.

here are the close images of S. lateriflorus and S. juncoides spikelet..
