Sir,

I attach two pictures which i recorded at the same place and on the same day and same time. I thought this pictures belong to some grasses. But as i was searching the net i think these two pictures may also come from the same cyperaceae species i posted in this thread.

Any chance of Eriophorum comosum?

Regards,

surajit

Good evening Sir,

I realize that i have mixed up things. The added photographs are of Typha, certainly.

But, i failed to find any Fimbristylis species in FoC and in FoP that conform to this originally intended post of cyperaceae member.

The only Fimbristylis with trigonal culm that comes closer to the height of this species is Fimbristylis umbellaris.

I paste below the culm sizes of all Fimbristylis species available in Flora of China and Flora of Pakistan websites.

• Fimbristylis ovata = Culms tufted, 15-35 cm tall

Usha Di,

I can only compare culm lengths, do not understand features.

Thank you & Regards,

Dear Surajit Ji,

I don't think your plant is Fimbristylis.....rather it looks a Scirpus sp. to me.

Experts pl validate.

Regards,

Ritesh. 

[manoj chandran]

It may not be Fimbristylis as well. Check under Rhyncospora and Scirpus too. Rhyncospora scirpoides also has similar structure.

[surajit koley]

Good evening Ritesh Ji,

I will search for Scirpus species.

Thank you very much,

Regards,

surajit

Good evening Sir,

I will search both Rhyncospora and Scirpus.

Thank you very much.

Sir,

This should be Scirpus grossus L. f. (Actinoscirpus grossus (L. f.) Goetgh. & D. A. Simpson var. grossus), i think.

Thank you.

surajit
