Poaceae, Cyperaceae and Juncaceae Week ::Cyperaceae » Kyllinga brevifolia?? at Navi Mumbai :: PKA4:: 12 posts by 4 authors. Attachments (2)

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.)  –

  2. important – Ispot
  3. most important – http://plants.jstor.org/flora/flos004255 (see the right pane of this page for citation of F. I. and Fl. Br. Ind.)

Thank you,

C. leucocephalus Retz. (of FBI) is BSI’s eflora–  which probably Kyllinga like.

C. leucocephalus non Retz. is BSI’s eflora.
This species probably the non Retz.
Certain Flickr ac has images –
Thank you
BSI species list of Kyllinga can be viewed at link. 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. Biodiversity Library and page 11 of Archive)
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.
