Kobresia fissiglumis C. B. Clarke

in Hook. f., Fl. Brit. India 6: 696. 1894.

Lectotypus (designated here): Western Nepal, Nampa Gadh , 3700-4000 m, 25.VII.1886, J. F. Duthie 6092 ( K [ K000794669 ]!, arrow, photo;iso-: DD!)( Fig. 3 ).

The protologue of K. fissiglumis cited the collection of J. F. Duthie 6092 from Western Nepal. We have examined image of the relevant collection at K [K000794669] and the specimens at CAL and DD. The sheet at K has two plant specimens with the same field data in two different labels and both of them are from female plant with a determinative slip of C. B. Clarke in his own handwriting. There are four herbarium sheets of Duthie 6092 at DD, one of them is a male plant and three others of female plants but the label data of all these specimens are written by pen and it has now became invisible due to the ageing. There is a herbarium specimen of a male plant at CAL collected from Kumaun, Palang Gadh Byans,Western Nepal. Duthie’s collection at BM with the same field number i.e. Duthie 6092 collected from Kumaun, Palang Gadh, Byans, 11000-12000 ft. has been annotated as “ Hemicarex trinervis Benth. & Hook. f. forma? Spicisnigrescentibus”. According to RAJBHANDARI & OHBA (1991), it is Kobresia trinervis Boeck. Kobresia fissiglumis has been described on the base of the female plant deposited at K also the male plant of Duthie’s specimen is cited bearing the same collection number at K. The characters of the female spikelet are most important in identifying the different species of Kobresia and hence a female specimen at K is being designated here as the lectotype.
