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

 in an umbel less than 1 in. diam. In Wight n. 1892 (type of Isolepii 

 gracilis, Nees) the stems arc long, very slender; the umbel is lax, some pedicels 

 I in. long. 



10. SCZRPTTS, Linn, (partly). 



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

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

 sometimes few-fld. (lower glumes subdistiohous 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 8. Isolepis) sometimes broad ovate. 

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

 appendaged. Style long or short, glabrous, 3-fld or 2-fld, 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 

 Fimbristi/lis differ by the enlarged style-base (separated from the nut by a constric- 

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

 lignlate, laoiniate (to the base in the Indian species).
