Please identify this herb from Kannur District of Kerala. Leaf midrib underside is slightly spinous..

Any idea about the family or genus ?
orchid?

I do not think so. 

Cyperaceae family

Family is Cyperaceae.The genus may be Carex.

Now the same plant has grown further with large sized inflorescence. Hope the identification could be easier...
