Perennial, attaining lO^decim. in height, flaccid, quite glabrous, 

 standing in water ; roots fibrous. Rhizome horizontally repent, slender, 

 white, soft; nodes remote, with a sheathing membranaceous scale at each 

 node. Leaves few, erect, sheathing towards the base (the sheath not 

 connate and thinly membranaceous), elongate, slender, triquetrous with 

 smooth edges, acute at apex, smooth, green, IA-,5 mm across, shorter than 

 the stem. Stem solitary, erect, slender, very acutely triquetrous with 

 smooth edges, smooth, green, aphyllous, the base enclosing by the lower 

 portion of leaves. Inflorescence pseudo-lateral, sessile, much shorter than 

 the bract, loosely and divaricately few-branched, 3-8-spiculose, simply raceme- 

 like or compound ; racing short, geniculate, triquetrous, not scabrous, branches 

 often binate (the inferior one longer) to a joint of the rachis, unequal in 

 length, compresso-triquetrous, attaining 4cm. long, the superior ones shorter; 

 bracteoles subulate, carinate dorsally, mostly thin-membranaceous, the inner 

 one thick and gibbose at the base, the longest one attaining 22mm. in 

 length ; bract continued to the stem, erect, slender, acute, triquetrous, 

 not scabrous, green, about 10-19 cm. long. Spicule ovato-cylindrical or 

 cvlindrico-fusiform, acutish on both ends, 10-16 mm. long, many-flowered, 

 bay-ferruginous, pedicellate and mixed with sessile ones ; rachilla glabrous. 

 Glumes imbricated, ovato-lanceolate, acute or obtuse or emarginate and 

 with a minute mucronate tip which is the apical end of the midrib, 

 ciliolate on margin, membranaceous, fulvo-ferruginous, but green in the 

 midrib, nerveless on sides of the midrib, concave, ecarinate, 5-1-6 mm. long. 

 Sette 4, twice or a little more as long as the caryopsis, somewhat unequal 

 in length, erect, setaceous, tapering, rigid, spreadingly spinuloso-pubescent, 

 fulvous. Stamens 2 ; filament filiform, exceeding the glume, glabrous ; 

 anther lato-linear, mucronate at apex, 2 mm. long. Style long, filiform, 

 exserted, deeply bifid; arms slightly shorter than the main portion, filiform, 

 obscurely puberulent. Caryopsis stramineous, lato-obovoid, shortly attenuat- 

 ed at the base, compressed with obtuse edges, smooth, 2 mm. long, cuspidate-
