Spikelets unisexual ; staminate spiUelets 2-flo\vered, in twos or threes on the continuous 

 rachis, the normal sroup consisting' of a pair of sessile spikelets with a single pedicellate spikelet 

 between them, this sometimes reduced to a pedicel i>r wanting; glumes membranaceous, 

 obscurely nerved : lemma hyaline, nearly as long as the glumes, awnless, 5-nerved ; palea 

 liyaline. a little shorter than the lemma ; stamens 3 ; pistillate spikelets 3 together, i fertile and 

 2 sterile at the base of the inflorescence: fertile spikelet consisting of 2 ghmies. t sterile lemma. 

 a fertile lemma, and a palea: glumes several-nerved, hvaline below, chartaceous in the ni")])er 

 narrow pointed part, the first very broad, infolding the spikelet, the margins infolded beyond 

 the 2 lateral stronger pair of nerves, the second glume narrower than the first, keeled : sterile 

 lemma about as long as the second glume, similar in shape, but a little narrower, hyaline below, 

 somewhat chartaceous above : fertile lemma hyaline, narrow, somewhat shorter than the sterile 

 lemma ; palea hyaline, narrciw. shorter than the lemma : sterile sjsikelets consisting of a single 

 narrow tubular glume as long as the fertile spikelet. somewhat chartaceous. Tall branched 

 grasses with broad flat blades, the monoecious inflorescences numerous on long, stout ])e(luncles 

 clustered in the axils of the leaves, each inflorescence consisting of an ovate or oval, pearly 

 white or drab, beadlike, very hard, tardily deciduous involucre (much modified sheathing bract) 

 containing the pistillate lower portion of the inflorescence, the points of the pistillate spikelets 

 and the slender axis <if the staminate porti<in of the inflorescence pnitruding through the orifice 

 at the apex, the staminate upper portion of the inflorescence 2 to 4 cm. l<Mig. soon deciduous,
