Please help me to identify this Cyperaceae member. Its found in wetland plains. The height varies from proximity to water (taller on shores and shorter away from shore).

Habitat: wetland (marshy ground near a pond)

Height: 15-25 cm

Inflorescence: 2.5 cm long

Location: Kancheepuram dist., TN

Alt.: 15 m asl

Date: 09 May 2015

Time: 10:00 AM

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.

Prasad sir is correct Cyperaceae members require the dissection after that we can identify them..

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

It will help you...
