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
Glume 2.0 mm long with glabrous keel……………..…………..…var. stellulata

Please wait for experts view.

I have had an earlier post of Kyllinga … explained two species in that thread – efi thread.

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

As per key provided by Manudev Ji, i think, it is Kyllinga brevifolia Rottb. (Cyperus brevifolius (Rottb.) Hassk.).

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.

Reply from another thread: “Once again I convey my heartiest thanks to … I think my earlier post is same species as this one (Kyllinga brevifolia).

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!

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.

Cyperaceae
Kyllinga ¿ species ?

Place, Altitude: Prabalgad near Panvel … about 1000 ft asl
Date, Time: 11 JUL 10 … 08:36am
Habitat: along mountain trail
Habit: small erect herb; standing about 1 ft high (guess)
Apologies: Only one photo; the closeup is cropped version … these two views may not be sufficient for ID.

Any chance of Kyllinga bulbosa P. Beauv. ?

Dinesh Sir, the links below may help (may not as well!)-

Thank you

Can be Kyllinga bulbosa P. Beauv., need a specimen to confirm the identity.

Taking it as Cyperus tenuifolius (Steud.) Dandy as per Prasad ji’s publication:
On the identity and occurrence of Cyperus pseudoalatus and Cyperus richardii (Cyperaceae) in India– Prasad V.P.- Rheedea Vol. 31(2): 85–88 (2021) (Abstract: Cyperus pseudoalatus (Wad.Khan & R.D. Taur) Kottaim. (Kyllinga pseudoalata Wad.Khan & R.D.Taur) is reduced to a synonym of Cyperus tenuifolius (Steud.) Dandy, with critical discussion. Based on a careful scrutiny of the protologues and type images of Kyllinga bulbosa P.Beauv., K. tenuifolia Steud. and Cyperus richardii Steud., it is confirmed that the plants reported earlier from India and Sri Lanka as Kyllinga bulbosa (Cyperus richardii) are likely misidentified and represent Cyperus tenuifolius.)

This can be Cyperus brevifolius (Rottb.) Endl. ex Hassk. (Kyllinga brevifolia Rottb.) in flowering stage. But need to examine the specimen to confirm the identity.
