Glabrous. Stems 4-16 in., at top triquetrous, rather slender; lowest persistent 

 as torn fibrils. Leaves often as long us stems, -^g in. broad, weak; sheath dilated, 

 ferruginous or reddish. Inflorescence -5 in. in diam. ; bracts 3-5, up to 4r-6 in. long, 

 leaf-like. Spikelets numerous, i- in. long, nearly terete ; nodes of rhachilla short 

 with elliptic wings. Nutbearing glume ovate, bluut, triangular, 14-19-nerved. 

 Stamens 32; anthers linear-oblong, muticous. Nut oblong or somewhat obovoid, 

 trigonous, ashy black, f-f length ot glume ; style shorter than nut ; branches linear, 

 somewhat long. Cyperus dubius, Eottb. Descr. et Ic. 20, t. 4, fig. 5, brought here , 

 by all authors, is a Kyllinga, probably K. brevifolia, Rottb. ; the general appearance 

 of the head will not do for M. Dregeanus ; also in Kytlinga the style is always 2-fid, 

 in Mariscus always 3-fid. 



2. M. bulbosus, C. B. Clarice (not of S tend.) ; stolons slender, umbel 

 simple with short rays or subcapitate, spikes cylindric dense pale, spikelets 

 broad-oblong, bearing 1 nut. M. pictus, Nees in Wight Contrib. 90 (partly).

Glabrous. Stems 3-8 in., thickish, trigonous, striate ; stolons elongate, -^ in. 

 in-diam., clothed by oblong striate pale-brown scales. Leaves as long as stem, i- 

 $ in. broad ; lower sheaths much inflated, striated, brown. Spikes about 7, on rays 

 0-4 in., up to | by i in. ; bracts 5-7, up to 4-7 in., leaf-like. Spikelets T y-| in., 

 spreading at right angles. Nut-bearing glume ovate, acute, 11-17-striate, straw- 

 colour. Nut ellipsoid, trigonous, black -chestnut, f length of glume. 



Subgen. II. EU-MARISCUS. Base of stems not oblong thickened by 

 much dilated leaf-sheaths (though often shortly nodose). Rhacheola of 

 spikelets only breaking up at one node, viz. that above the two lowest 

 empty glumes. 



Sect. 1. Umbellati. Leaves green. Spikelets green or becoming yellow, 

 bearing 1-2 (very rarely 3) nuts. Lowest glume of spikelet (bracteole of 

 some) very acute, aristate. [JN early all are considered by Bentiiam as 

 varieties of his Cyp. umbellatus.} (Sp. 3-7.) 



3. BX. paniceus, Vahl Enum; ii., partly \ stolons long slender, umbel 

 simple, bract's 4-5 long, rays unequal usually short, spikes solitary cylin- 

 dric dense ebracteate, spikeletl small 1-fld.. in fruit broad-lanceolata 

 trigonous curved more or less recurved. Nees in Wight Contrib. 89 ;
