Stem about 3 feet high, sending out fibrous roots from its lowest 

 joints, erect, simple, except now and then at the base, smooth, 

 leafy, with 4 or 5 hairy knots. Leaves spreading, many-ribbed, 

 hairy, rough-edged. Sheaths long, ribbed, either nearly smooth, 

 or thickly clothed with soft deflexed pubescence. Panicle very 

 large and conspicuous, with numerous half-whorled, partly com- 

 pound, harsh, spreading branches, the lowex'most bracteated, as 

 it were, by a notched scal^ various in size and shape. Spikelets 

 drooping and finally pendulous, ovate-lanceolate, variegated 

 with purple and green, smooth to the naked eye, but appearing 

 minutely downy when magnified. The outer valve of the corolla 

 has 2 lateral ribs at each side, close together, distinctly marked, 

 veiy different from the more numerous but fainter ribs of B. ra- 

 cemosus ; awn purple, as far as we have seen longer than the 

 glume, and quite straight, inserted below the divided point j 

 inner valve much narrower, very thin, the green ribs fringed 

 with spreading bristles. Nectary of 2 notched scales. Styles 

 distant, very short, Anthers purple.
