Annual, or Biennial. June. 



A very distinct species from the preceding, more slender in habit, 

 and much less downy, not at all soft to the touch. The panicle 

 is generally simple, its branches longer, and less divided, rough 

 with minute bristles, not downy. Spikelets larger, more turgid, 

 rough to the touch, but naked and shining. Outer valve of the 

 corolla marked with 2 green ribs at each side, which are scarcely 

 at all prominent, nor are there furrows between them as in 

 B. mollis. No one who has seen the plants together can mistake 

 them. The. florets vary in number from 5 to 10. Authentic spe- 

 cimens, and Professor Schrader's accurate inquiries, have ena- 

 bled me to correct the synonyms of this species, and of B. ar- 

 vensis hereafter described. Much of the mass of error, which had 

 always enveloped this genus, was by similar means cleared away 

 in the 4th vol. of the Linnsan Society's Transactions ; but the 

 confusion among German authors, who had in vain undertaken 

 its particular illustration, could be set right by a consummate 

 botanist of that country only.
