Dry plains of INDIA ; from Kashmir to Upper Bengal, and southward to CEYLON. 

 BURMA, Wallich. DISTEIB. Warm regions generally. 



Steins erect in the first year, 4-8 in. high, leafy nearly to the spikes, then sending 

 from the base rooting and leafing flg. stolons all round. Leaves very variable, smooth 

 or scaberulous, ovate and in. long, or narrower and 1-1^ in. long, acuminate, 

 margins and mouth of sheath ciliate. Spikes 1-4 in., rachis and very short pedicels 

 pubescent. Spikelets |- in., crowded, in pairs face to face, simulating one spikelet 

 with 2 equal spinous glumes. Gl. II with broad hyaline margins towards the tip. 

 In all Indian specimens I find the spikelets in pairs, each with 2gl. I have not seen 

 the fascicled spikelets described in Gen. Plant. A small lower gl. is described as 

 sometimes present, and 5 spikelets as occurring on a single pedicel.

A perennial rather rigid grass. Leaves subulate, convolute. Spikelets 

 1-fld., in simple subspiciform racemes, biseriate (one usually imperfect) 

 persistent on the flattened truncate spreading articulate pedicels ; rachis 

 flexuous. Glumes 3, I and II empty, thickly coriaceous, I usually longest, 

 narrow, recurved, 3-nerved, subspinously pectinate, dorsally smooth ; II 

 lanceolate, spinously tubercled, embracing III (flg.), which is shorter, 

 hyaline, oblong, acute, ciliate; palea minute, linear-oblong, nerveless. 

 Lodicules 2, hyaline. Stamens 3, anthers oblong. Styles free. Grain free, 

 obliquely ovate-lanceolate.

Stems 3-10 in. wiry, creeping with many erect or spreading branches, leafy up to 

 the racemes. Leaves 1-3 in. ; lower sheaths short, mouth hairy j ligule 0. Racemes 

 26 in. ; rachis glabrous ; pedicels distant, narrowly cuneiform, margins winged 

 ciliate. Spikelets ^-i in., reddish-brown. The Indian specimens are small. The 

 pedicels are flattened and bear normally 2 spikelets, one well developed and fertile, 

 'the other imperfect with gl. I and II narrower of equal length and irregularly 

 spinously tubercled.
