Very near B. capillaris ; the spikelets are really solitary, but ofteiVelosely packed 

 in an umbel less than 1 in. diain. In Wight n. 1892 (type of Isolepis 

 graoilis, Nees) the stems are long, very slender; the umbel is lax, some pedicels 

 f in. long. 



10. SCIRPUS, Linn, (partly}. 



Herbs of very various habit, all glabrous (or the inflorescence slightly 

 hairy). Spikelets usually many -fid. (lower glumes spirally imbricated) 

 sometimes few-fld. (lower glumes subdistichous upper spirally imbricated). 

 Glumes 1-2 (rarely 3) lowest empty, several (rarely 1) succeeding with 

 perfect nut-bearing flowers, upper tabescent. Hypogynous bristles 7-1 

 setaceous, or 0, or (in S. littoralis and S. Isolepis) sometimes broad ovate. 

 Stamens 3-1, anterior ; anthers linear-oblong or oblong, crested or un- 

 appendaged. Style long or short, glabrous, 3-fid or 2-fid, base linear 

 or linear-conic, continuous with apex of nut. Nut trigonous or plano- 

 convex, sessile or nearly so. Species 125, all regions. 



This genus here includes (in several very dissimilar sections) all the scirpoid 

 species left after the neighbouring genera have been taken out. Eleocharis and 

 Fitnbristylis differ by the enlarged style-base (separated from the nut by a constric- 

 tion or a line) ; Fuirena and Bulbostylis have hairy leaves ; Eriophorum has bristles 

 ligulate, laciniate (to the base in the Indian species).

Boot fibrous. Stems 2-12 in. long, flaccid, in water or on mud. Leaves i-2 

 in. , very narrow. Peduncles 1-4 in. Spikelet -^-^ in., many- or few-fld. ; bract 

 usually shorter than the spikelet, or 0. Glumes ovate, obtuse, concave. Nut as 

 long as i-f glume ; outermost cells small quadrate-hexagonal obscure (i.e. nut 

 smooth or obsoletely reticulate).
