 glabrous. Leaves very fine, subulate, erect, chiefly at the base of the stem.. 

 Panicle loose, nearly simple or with few capillary branches bearing 2 or 4 

 pedicellate spikelets. Outer glumes usually about 3 lines long, very acute or 

 shortly pointed, prominently-nerved, glabrous. Flowering glumes glabrous on. 

 the back except at the base, the margins ciliate with long hairs, tapering into an
