or thickly clothed with soft deflexed pubescence. Panicle very 

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

 pound, harsh, spreading branches, the lowermost bracteated, as 

 it were, by a notched scale, 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, 

 very 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 ; 

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

 with spreading bristles. Nectary of 2 notched scales. Styles 

 distant, very short. Anthers purple. 



7. B. erectus. Upright Perennial Brome-grass. 



Panicle erect, slightly branched. Spikelets linear-lanceo- 

 late. Florets about eight, loosely imbricated, lanceolate, 

 compressed. Awn shorter than the glumes, straight. 

 Radical leaves very narrow, fringed with scattered hairs.
