Carex species

 

ID please:
Please identify the plant
Collected from Kotagiri, Ooty
Date of Collection. 20.06.2011
I found this plant growing in Darjeeling. It is almost like a weed on the borders of tea gardens. Few of the estate managers told me that they use this plant along with other herbs to make a concoction and
spray on tea bushes to control some pests.
The plant is almost a meter height
Herb
Dark pink stem
No flowers in this season

The vegetative stage indicate it as Eupatorium sp.?
It may be a Scleria species of Cyperaceae.
Any picture at flowering stage?
I think it represents Carex sp.
Yes it is a species of genus Carex (Cyperaceae).
But am not able to identify due to the lack of literature.
