Pseudechinolaena polystachya (Kunth) Stapf ??

Thank you very much for the ID suggestion.

It is close to Pseudechinolaena polystachya, a very common common grass grows in low altitude, my plant also Pseudechinolaena, but rarely grows only in high altitude shady hill area and its leaves are wavy (closeup images will be provided soon) and too little.

I guess this is the only sp. having distribution in India and the elevation range is 900-2100m.

Yes, it is grows in high altitude and very close to Pseudechinolaena polystachya, thank you very much for ID my plant,

only a slight difference that is outer sides of both sepals are hairy,

Pseudechinolaena polystachya (Kunth) Stapf !

Yes, …, recently reported from Andhra Pradesh also; plenty population under the shade of moist places.

Nice to see this record from Kathmandu. Was it reported earlier in Nepal?

1 image.

Interesting. It is a grass of dense shady and moist localities. I wonder how it would be found on Tibetan plateau.

This is not Tibetan Plateau rather it is a valley and it was on moist shady area.

Concur with … it is seen in many places in karnataka also.

Id is Ok. Its presence in the Kathmandu valley is understandable. But, in the reference you posted, there is mention of ‘Tibetan Plateau’ also, which is surprising. May be they are talking about moister Eastern part of Tibet (adjoining Yunan)
What is the reference book?

OK …! By the way POWO, WCSP, CoL and GBIF have their distribution for Tibet.
