SIKKIM ; alt. 12-13,000 ft., Lachen Valley, at Moraay, J. D H. 



Rhizome very short, woody ; roots long, thick, tough. Stems csespitose. Vernal 

 leaves 2 by T L in., summer 5-8 in., tip long-caudate, filiform, scabrous; sheath 

 testaceous, becoming brown, not fimbriated. Spikes T ^ in. broad; bracteoles (cor- 

 responding to "glumes" of carex) rhomboid-ovate, brown, yellow on back, lower 

 often more or less aristate, upper obtuse. Q-lwne (i.e. utricle), subspathiform, at 

 top obliquely truncate, with 2 green ribs ; a minute rudiment of rhachilla is some- 

 times within it. Nut linear-oblong, brown, as long as glume; beak -f length of 

 nut, exsert. Boeckeler united with K. seticulmis, filicina, and his description of 

 seticulmis is mainly drawn from filicina (he had only a scrap of K. seticulmis.) 



2. XL. Hookeri, BoecJc. in Linnsea, xxxix. 4; stems rabher slender 

 4-12 in., vernal leaves flat linear-lanceolate tipped, spikes (all fern, at base 

 male at top but see var. /3) H-lf in. linear, narrower interrupted at base, 

 fern, glume deeply split, style 3-tid, nut (including exserted beak) | in.

SIKKIM, alt. 11-13,000 ft.; Lachen, J. D. H. ; Singale-lah, C. B. Clarke. 



Closely allied to K. seticulmis, but larger in all its parts. Leaves % in. broad ; 

 summer leaves 1 foot long caudate-tipped. In this group, the stems in flower are 

 short, surrounded by lanceolate-tipped leaves ; in fruit the stems are greatly 

 elongated, with long-caudate summer leaves. 



Var. ? (3 dioica ; spikes (very many seen) unisexual.- SIKKIM ; Namdee, alt. 

 12,000 ft., Pantling. Male spikes 2 by | in. Fe-m. spikes 2-2 in., in two examples 

 branched. These are spring examples, and may be K. Hookeri, or a new species 

 allied thereto. 



3. XL. ang'usta, G. B. Clarke ; stems slender 1-5 in., all leaves very 

 narrow, spikes dioecious males short (on short stems) sublanceolate fern, (on 

 elongating stems) linear-filiform interrupted at base, style 3-fid, nut nearly 

 as in K. seticulmis, but beak shorter. 



SIKKIM ; Sundukphoo, alt. 12,000 ft., C. 3. Clarice. 



Vernal leaves 2 by J T in ; summer leaves 4-5 in. Male stems 1-2 in.; male 

 spikes -f by |-| in. ; male bracteoles elliptic-lanceolate, brown, back green, edges 

 scarious. Fern, stems ultimately 4-5 in. ; fern, spikes (young) 1J by -^ in. 



4. XL. vag inosa, G. B. Clarke ; culms 4-8 in. clothed some way up 

 by withered sheaths, leaves all filiform, spikes (mostly dioecious) male 

 linear-oblong fern, linear with distant bracteoles, style 3-fid, nut linear- 

 oblong, beak length of nut. 



SIKKIM; Lachen Valley, at Momay, alt. 15,000 ft., J. D. H. 



Stems covered up to -f their length by scarious flaccid sheaths. Leaves 2-6 

 in., at base scarcely - in. broad. Male stems about as long as female. Male 

 spikes f by -^ in. "Fern, splices (sometimes having male spikelets at top) 1 in., 

 most of the bracteoles (except a few at top) not imbricated. 



5. K. trinervis, BoecJc. in Linnsea, xxxix. 548, in note; stems 2-8 

 in. rather slender, summer leaves very long not long-caudate, spikes 

 (usually dioecious) fern. 2i in. linear, male bracteoles elliptic-oblong obtuse
