Scirpus.'] CLXXII. CYPERACE^;. (C. B. Clarke.) 663 



"both ends ; outer cells subhexagonal, ultimately lax hyaline (so that a nut appears 

 microscopically hyaline-margined). Ripe examples of this species, with fallen glumes, 

 are easily seen to belong to Scirpus not Cyperus ; but young small examples are 

 difficult to distinguish from Cyperus pygmceus. 



Sect. 7. MICRANTHI. Small tufted annuals. Stems with few short 

 leaves near base. Spikelets 1-4, capitate, lateral dense-fld. Bristles 0. 

 Style very short, branches short, recurved. Anthers small, oblong. 



25. S. Isolepis, BoecJc. in Linnsea, xxxvi. 499 ; stem setaceous with 

 one spikelet, glumes obovate obtuse, style 2-fid, nut oblong-obovoid smooth 

 reticulate, black. Hemicarpha Isolepis, Nees in Edinb. N. Phil. Journ. 

 xvii. 263, and in Wight Contrib. 92.

Glabrous. Stems -4 in. Leaves 1-2, -1 in., linear. Spikelet T V~F ^ n -> 

 rectangularly divaricate, 20-40-fld.; bract -! in., erect, as though continuing 

 stem. Glumes rhomboid, deciduous, rarely minutely mucronate. A thin hyaline 

 obovate irregular scale as long as nut (very rarely 2 scales) is sometimes present, 

 oblique lateral between nut and glume. Stamen 1, lateral. Style less than nut, 

 deciduous, style-base not dilated. Nut a little shorter than glume, biconvex. 



26. S. squarrosus, Linn. Mant. 181; stem slender with few spike- 

 lets, glumes narrowly obovate long-caudate, style 3-fid, nut narrowly 

 obovoid smooth reticulate yellow-brown or finally black. Rottb. Descr. et

 CEYLON. DISTEIB. Trop. Africa, Madagasc., Java, China. 



Glabrous. Stems 2-16 in. Leaves short, in the Indian specimens commonly 

 1-2 in., linear. Spikelets 1-10 (usually 2-4) capitate, divaricate, - in., densely 

 softly echinulate from tails of glumes. Glumes very many, caducous, small, 

 narrowly obovate, suddenly narrowed into the ligulate curved subobtuse tail. 

 Stamen 1, sometimes 2 ; anthers not crested. Style scarcely nut, deciduous, style- 

 base scarcely dilated. Nut a little shorter than glume (without its tail), nearly 

 regularly trigonous.

S. QUADEANGULUS, Don Prodr. 40. Sc. Donianus, Spreng. Syst. Cur. Post. 28; 

 perennial ; stem 1 ft. strict, 4-gonal, base sheathed by 2-3 leaves ; leaves linear 

 erect often longer than the stem, channelled, keeled beneath, smooth below, scabridly 

 toothed on the margin towards the apex ; umbel compound, proliferous, not a little 

 like Juncus acutiflorus, shorter than the 5-leaved involucre ; spikelets small, ovate 

 brown ; few-fld. glumes ovate concave mucronulate ; style not jointed on the ovary.
