This herb was photographed at CBD Belapur hills in July'09.  
As per ..., this looks like some Kyllinga sp (most probably Kyllinga brevifolia) but needs further validation... 
Family: Cyperaceae
This plant looks different than any Kyllinga species. You can search and check Kyllinga heads in the net. I think it might be Cyperus obtusiflorus (incl. subsp.)  -

Thank you,
C. leucocephalus Retz. (of FBI) is BSI's - http://efloraindia.nic.in/efloraindia/speciesDesc_PCL.action?species_id=3438 which probably Kyllinga like.
This species probably the non Retz.
Certain Flickr ac has images -
Thank you

BSI species list of Kyllinga can be viewed at http://efloraindia.nic.in/efloraindia/speciesList_PCL.action?resultType=genusWise&parent_Id=3218&parent_Name=kyllinga. Google search of each species would provide photographs of each species from authentic source. In fact to my little knowledge no Kyllinga can have so many florets per spikelet.
Unfortunately macro of heads are not available at -
Thank you
This is Sorostachys pulchellus (R. Br.) Lye of BSI, the current accepted name is C. pulchellus R. Br. and I hope this is the species image - https://www.anbg.gov.au/cgi-bin/phtml?pc=dig&pn=28989&size=3
It is Cyperus leucocephalus Retz.
Attached here related FBI entry of Sorostachys leucocephalus  (Retz.) Lye (http://www.theplantlist.org/tpl1.1/record/kew-266001)
One difference I find -
  1. spikelets 10-20 flowered = pulchellus Non Retz.
  2. spikelets 8-12 flowered = leucocephalous Retz. (ref. http://biodiversitylibrary.org/page/4506832#page/296/mode/1up and page 11 of http://www.archive.org/stream/mobot31753003566566#page/11/mode/1up/search/cyperus)
Please check the specimen as per above key/description.

Cyperus leucocephalus and C. pulchellus are very similar, difficult to differentiate unless the specimens are studied. Both were treated under Sorostachys by earlier workers, but now under Cyperus. I think ... is correct, it is  C. pulchellus, usually found in Western India.
