 gin, at first longer, but at length shorter than the culm: nheatlhs smooth, n\tm. 

 bmnaceous, whitish. Spikelets 2 to t>, usually about 4, the lower onei s-juie\taat 

 distant, the Upper oneea little crowded ; the terminal one mnstly .stain inate below 

 the others generally androgynous with a few staminate glumei at each end : ocoa-'

 linear-lanceolate, tapering to a filiform point, greet, Ov ertopping the culm, scabrous 

 un the margin, striate and considerably pubescent ; sheaths villous, those at am! 

 near the base of the culm often dark purple. Spikelet* commonly 3, (occasionally 

 4, sometimes only 'J.) about three fourth/? of an inch long, all approximate; the 

 terminal one androgynous ; the others entirely pistillate, nearly sessile, with each
