SiKKiM ; alt. 12-13,000 ft., Lachen Valley, at Moraay, .7. O. H. 



Rhizome yery short, woody ; roots long, thick, tough. Stems casspitose. Vernal 

 leaves 2 by ^^ in., summer 5-8 in., tip long-caudate, filiform, scabrous j sheath 

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

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

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

 top obliquely truncate, with 2 green ribs ; a minute rudiment of rhaohilla Is some- 

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

 nut, exsert. — Boeckeler united with K. seticulmis, fiUeina, and bis description of 

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

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

SiKKiM, alt. 11-13,000 ft. ; Lachen, J. B. H. ; Singale-lah, 0. B. Olarhe. 



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. — SlEElM ; Namdee, alt. 

 12,000 ft., Pantling. — Male spikes 2 by ^ in. Pum. spikes 2-2^ in., in two examples 

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

 allied thereto. 



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

 narrow, spikes dicBoious males short (on short stems) sublanceolate fem. (on 

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

 as in Z. seticulmis, but beak shorter. 



SiKKiM ; Sundukphoo, alt. 12,000 ft., C. B. Clarhe. 



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

 spikes ^1 by ^-^ in. ; male bracteoles elliptic-lanceolate, brown, back green, edges 

 scarious. Fem. stems ultimately 4-5 in. ; fem. spikes (young) 1 J by ^V •°' 



4. K. vag'lnosa, C. B. Clarhe ; culms 4-8 in, clothed some way up 

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

 linear-oblong fem. linear with distant bracteoles, style 3fid, nut linear- 

 oblong, beak i length of nut. 



SiKKiM; Lachen Valley, at Momay, alt. 15,000 ft., J. D. S. 



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

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

 spikes f by ^ in. Fem. spikes (sometimes having male spikelets at top) 1 in., 

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



5. Ki trlnervls, BoecTc.in Linnsea, xxxix. 548, in note; stems 2-8 

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

 (usually dioecious) fem. 24 in. linear, male bracteoles elliptic-oblong obtuBe
