Carex is a large and difficult genus.  I photographed 3 Carex in my own 
village in the UK this year and have only, so far, been able to name one of 
them.  There is a guide to Carex published by the BSBI which I had a copy 
of at one time but was damaged and discarded; I do not currently have the 
budget to buy an up-dated version.  Without it I will struggle (without 
help) to name the other two.

In the UK we are blessed with The Botanical Society of the British Isles 
(BSBI) which has a Panel of Referees and Specialists available to have 
material sent to them to identify.  There are a number of specialists 
available to accept specimens of *Carex* (either pressed and dried or in 
some cases fresh) with certain ones with particular expertise in particular 
groups or aggregates.  *In all cases mature fruits and underground parts 
should be sent.*  I doubt if many of them would be able or willing to 
attempt to name specimens on the basis of photos alone particular those not 
of greater close-ups or with more mature fruits than shown in these images.

Stewart commented that like the Carex alpina complex in the Himalaya, the 
Carex nivalis complex is a very difficult one and the authorities do not 
yet agree on the best way to handle it.  Some one should study the group 
cytologically to try and disentangle the threads.  There seem to be groups 
which Kukenthal in his Monograph called froms.  Some have called them 
varieties and still others consider some of them to be distinct species.

Having said that, Stewart enlisted the help of various Carex specialists to 
name the sedges of Pakistan & Kashmir incl. in the summer of 1964 Miss 
Sheila Hooper who went over the rich material at Kew with him and made the 
following key for the Carex gilesii-Carex griffithii-Carex mivalis complex:

*1. Terminal spike usually entirely male; utricle distinctly but shortly 
beaked  C.gilesii*
* Terminal spike female below, male above; beak from almost nil to 
distinct  .....2*

*2. Glumes and utricles black 
...............................................................................3*
*    Glumes and utricles cinnamon brown ........................ C.oliverii 
(C.nivalis forma cinnamomea)*

*3  Glumes and utricles golden 
................................................ C.luteo-brunnea*
*    Glumes and utricles not golden 
........................................................................4*

*4  Glumes with a conspicuous green arista which exceeds the utricle  ..... 
C.nivalis forma griffithii*
*    Glumes with a short mucro; beak of utricle short  
...................................C.nivalis  var. nivalis*

*Stewart records Carex nivalis as common from 3300-5100m*.

*Khelanmarg is closer in altitude than Gulmarg to this altitudinal 
range but the complex is not well known, assuming it.  These iamges look 
similar to the ones taken at Gulmarg.*
