Cyperus rotundus ?;
Grass for ID : Oman : 221012 : AK-2: A grass with reddish brown flowers seen growing wild at a farm in Muscat on 27/1/2012.
This is a very common grass.
This is not a grass, but a sedge – Cyperaceae, probably Cyperus rotundus
how can alay person tell the difference…
secondly… may be a tall order, but… do you have a easy to understand key for te common grasses… masy be by the regions in india? I too am unable to know the difference between grass & sedge. For me, they all seem similar.
If this grass is a cyperus… its called Mustaka in ayurvedic medicine
and yet some silly professors are using the “roundup ” weed killer herbicide to kill it off… http://www.jtropag.in/index.php/ojs/article/viewFile/127/121 I wonder what the motivation is for these professors…?? The link you have pasted shows Cyperus rotundus L., MUSTAKA in Sanskrit and MUTHA in Bengali, very common, about 2 feet or more, roots smell like DHUNA.

I do not have clear conception over C. rotundus. According to “Bengal Plants” it is a slender glabrous sedge, stolons thickening into black, woody, ovoid tubes.
Kindly help in identification. Is it Cyperus rotundus?

I do not have clear idea on C. rotundus. The key in “Bengal Palnts” informs : “Rhizome stoloniferous; stem at base nodosely thickened, and suddenly contracted into a wiry rhizome.”

Taking cue from … i searched “Pycreus species in West Bengal”.
A document, available at – http://kuedu.academia.edu/ProfSobhanKrMukherjee/Papers/921505/DIVERSITY_OF_AQUATIC_AND_WET_LAND_PLANTS_OF_WEST_DINAJPUR_DISTRICT_WEST_BENGAL_INDIA, informs me that two Pycreus species in West Bengal are P.pumilas and P.sanguinolentus.
This sage is not Pycreus pumilas, because –
This description of Pycreus sanguinolentus –
However, at least two more Pycreus species available in West Bengal –
Attaching one more pic that might be same species as my previous uploads in this thread. Could it be P. sanguinolentus?
Seems to be a variant of Cyperus rotundus, may be subsp. tuberosus or Cyperus bifax?
