Tried possible options but could not conclude. Hope ... can help.

I think it may be from Cyperaceae
I checked but could not come to conclusion. Not C. rotundus, is it ? 

... did quite a number of grasses
may be he would know
1: what this is
2: what to look for
3: what is the proper way to photograph unknown grasses

It is a sedge. Family Cyperaceae, probably genus Kobresia

Thank you ... for the lead but it is so difficult to nail the correct ID.

Anyway, I have guessed as Kobresia simpliciuscula (Wahlenb.) Mack..
