Throughout INDIA, alt. 0-4000 ft., from KASHMIR and ASSAM to CEYLON and 

 SINGAPORE. DISTRIB. Warm regions. 



Stems tufted, 2-10 in., bristle-like, striated. Leaves as long as ^ stem ; sheaths 

 usually with needle-like hairs at least in their throat. Capitulum -| f in. diam. ; 

 bracts shorter, or much longer, than head. Spikelets - in., oblong-lanceolate. 

 Glumes boat-shaped, ovate, scarcely acute, rusty brown with green keel, margins 

 minutely ciliate, sides puberulous or glabrate. Nut as long as i glume.

 there are intermediates which I cannot sort between the two; Wight regarded 

 all as one species. 



2. B. subspinescens, C. B. Clarke; stem hairy with abont 10 

 spikelets in an almost prickly head, style 3-fid, nut pale brown.

Whole plant pubescent. Stems 4 in., rigid, curved. Leaves as long as stem. 

 Spikelets nearly ^ in., hard, almost stellately spreading ; bracts about as long as 

 the head. Glumes scarcely keeled, densely pubescent. Otherwise as B. barbata, of 

 which it might be treated as a var. growing in sea sand. 



3. B. capillaris, Kunth Enum. ii. 212 (see p. 205) ; stem glabrous, 

 spikelets nearly all solitary in a simple or compound umbel, style 3-fid, 

 nut pale transversely undulate. Scirpus capillaris, Linn. Mant. 321.

Very common from the HIMALAYA, alt. 0-8500 ft., to CEYLON. DISTRIB. Warm 

 regions of Old World. 



Stems tufted, 4-10 in., slender, striate, glabrous under umbel. Leaves as long as 

 --! stem, bristle-like, nearly glabrous; sheaths with needle-like hairs at least in 

 their throat. Umbel very variable; in form densus (sp. Wall.) umbel very com- 

 pound dense with spikelets ; in trifida (sp. Kunth) umbel with 3 or not rarely 

 2-1 spikelets. Spikelets in the Indian plants solitary, in., ellipsoid or oblong, 

 6-15-fld. Glumes boat-shaped, ovate, obtuse, brown or blackish, puberulous, keel 

 green scarcely excurrent in a mucro. Nut as long as f glume. Some Indian 

 specimens have stems 16 in. with large compound umbels. I cannot separate this 

 specifically from the American type capillaris ; the shape of the outermost cells of 

 the nut is* identical in the two, the superficial difference in marking is often imperfectly 

 developed.
