litems 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 scabernlous, ovate and J 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 i-J in., crowded, in pairs face to face, simulating one spikelet 

 with 2 equal spinous glumes. 61. II with broad hyaline margins towards the tip. — 

 In all Indian specimens I find the spikelets in pairs, each with 2 gl. 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 subspioiform 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. Stamiens 3, anthers oblong. Styles free. Grain free, 

 obliquely ovate-lanceolate.
