sk2015sept17/17 - Cyperus WHAT?

[surajit koley]

I simply give up. It's either C. paniceus (Rottb.) Boeckeler or C. cyperoides (L.) Kuntze.

Photographed today (26-Sept-2015) in Hooghly.

Dear Dr. Garg

      Cyperus cyperoides and allied species are often confusing, very difficult to identify. I think it can be treated as Cyperus cyperoides rather than var. roxburghianus (C.B. Clarke) Kuk. of C. paniceus

 

Best regards

V.P. Prasad

With full respect to Dr. Prasad Ji, I beg to differ. Though C. cyperoides (L.) Kuntze can have a single floret in a spikelet, the 3rd glume would have 3 conspicuous green veins (ref. FoC), the same can be seen in Clarke's illustration (no.6). Else there would be more than one floret and thereby nuts. In my species only middle nerve of the glume is green and conspicuous (as can be seen in the illustration no.2).

So, I would rather go with C. paniceus (Rottb.) Boeckeler.

Thank you

Regards
