Key to the species from efloraofindia thread:
  • Inflorescence of 1–3 sessile, white or greenish white globose spikes, the central spike larger than others; nut bearing glumes winged; glumes white, winged towards the distal end, wings ciliate ……......................K. nemoralis
  • Inflorescence a single globose spike, green to yellowish green; nut bearing glumes not winged; glumes green, acutely keeled, keel ciliate or glabrous……………..........K. brevifolia

There are two infraspecific taxa for Kyllinga brevifolia. A key to the subspecies is given below..

Key to the subspecies

  • Glume 2.5- 3mm long with ciliate keel……………….………...….var. brevifolia

Grass ID request - RK16 - 15-Oct-2012: This grass (?) seen in Karjat area with three leaves and flower in the central node.
Seems to be a Kyllinga sp., a member of Cyperaceae - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=117357.
Please wait for experts view.
I have had an earlier post of Kyllinga ... explained two species in that thread - https://groups.google.com/d/topic/indiantreepix/0IlSLdVmEyg/discussion.

Single green globose spike suggests this might be Kyllinga brevifolia Rottb. Descr.
Kyllinga brevifolia
Yes it is Kyllinga sp. of Cyperaceae

Cyperus bravifolius (Rottb.) Hassk. Photograph from Satpura Tiger Reserve Seoni M.P. please validate 
Two more similar looking species, with tufted culms -
i) Kyllinga cylindrica Nees should have more cylindric (three-fourth inch) spike
ii) Kyllinga squamulata Vahl is with leaves often longer than stems, and distributed in Western India, Kashmir.

This is a common sedge along water channels, this one shot from around wheat fields of my native place in Kaithal. I hope this should be Kyllinga brevifolia Rottb. Please correct me if I am wrong..
Nice photographs ...
I can see ... already confirmed the ID - efi thread:)

Another small, less than 6 inches cyperaceae, in front of my house, photographed today. (3.10.14)
It is Kyllinga brevifolia Rottb. 
Once again I convey my heartiest thanks to .... I think my earlier post is same species as this one.

It is hard to believe that this small plant can be Kyllinga brevifolia Rottb. But i have no other option, for if it would had been at least 6 inches high and with reddish/brownish spike i might have think of Rhynchospora wallichiana Kunth!
Recorded on 31/8/13, in front of my school.

Yes Sir, I am surprised that these are significantly smaller than K. nemoralis, and also much less spread.
Yes, it is Kyllinga brevifolia

This is my 3rd upload of this species, recorded yesterday. This is time it is rather stouter than the previous two.
Poor picture quality is due to cloudy day, low light in bamboo thicket, exhausted camera life!

Earlier at https://groups.google.com/d/msg/indiantreepix/HUoQO2C7JHQ/_X1xUFdcT18J, one of my uploads has got the ID of Kyllinga nemoralis.
The plant posted here looks a bit different in context of the inflorescence - please therefore validate the ID in this post.
In the northern Konkan and Western Ghats of Maharashtra, we have at least following species of Kyllinga reported:
  1. K. brevifolia
  2. K. bulbosa
  3. K. nemoralis
  4. K. melanosperma
  5. K. squamulata
Very eager to see uploads of various species of Kyllinga.
I was trying to understand various Kyllinga mentioned by ..., but....... :(
Descriptions can be read in Flora of British India -

In our group we have posts of other two species.
Many thanks ... I am hoping many of us share their sightings of various species of Kyllinga.
The pictures at the links are good; but familiarity with grasses and sedges is absolutely low - not yet able to grasp the differences.
"we are in the same boat brother..."
Good morning ...
According to Flora of British India, K. cylindrica Nees is scattered widely in India, not plentiful anywhere. I am thinking if your species https://groups.google.com/forum/#!msg/indiantreepix/HUoQO2C7JHQ/_X1xUFdcT18J can be the same.
I think same as in another thread:

Thanks ..., I have revised my notes accordingly.

Location: Nagarkot,  Kathmandu
Date: 12 September 2020
Elevation: 2044 m.
Habit : Wild

It may rather be from Cyperaceae.
Cyperaceae
Could be Cyperus sp 

No. of leaves at the base of inflorescence..???

It should be in the images, there are 5.
Close to Cyperus brevifolius (Rottb.) Hassk. or Cyperus mindorensis (Steud.) Huygh
Need to check spike and nuts.
This seems to be Kyllinga brevifolia, but need to be confirmed with specimens.
