Root of numerous downy fibres. Stem erect, smooth, round, sim- 

 ple, from two to three feet high. Leaves long, broad, striated, rough 

 and hairy above, beneath smoother. Sheaths short, close, smooth, 

 striated. Ligula very short, obtuse, torn. Inflorescence a large, erect, 

 or slightly drooping panicle : the lower brandies half whorled, and 

 subdivided; the upper mostly short and simple; all roughish and 

 angular. Spikelets ovate-lanceolate, nearly erect when in flower, but 

 drooping when in seed. Florets about ten, at first closely imbricated, 

 afterwards more remote, and nearly cylindrical, by the sides becoming 

 more inflexed. Glumes unequal, the margins pale and membranous ; 

 the outer smallest, keeled, and each side with two prominent ribs ; the 

 inner valve ovate lanceolate, keeled, and with several more or less dis- 

 tinct ribs. Glumelles equal : the outer ovate oblong, the margins and. 

 bifid extremity membranous, the sides inflexed, smooth, or the extre- 

 mity sometimes roughish, with minute points ; the three ribs on each 

 side, as well as the keel, obscurely marked ; awn frequently shorter 

 than the valve, rough and waved : inner valve membranous, with two 

 lateral green ribs, ciliated with white hairs. Stiymas feathery. Seed 

 oblong, channelled on one side, the apex downy. 



Habitat. Corn-fields, not uncommon. 



Annual ; flowering from July to August. 



In some countries as Hanover and Germany this species of grass 

 grows in such abundance amongst the Wheat and Rye, as to render 

 the crops of very inferior value. The flour produced from its seed is 

 small in quantity, and is said to impart a bitter taste to the bread, and 

 to produce effects similar to Lo'lium temulen' turn. It was an opinion 

 entertained by the ancients, that Wheat and other grain degenerated 

 into grasses, and that this and the following species have gradually 

 lost their claim amongst the grain-bearing grasses, and to have dege- 

 nerated from Rye ; hence they were called smooth and doivny .Rye- 

 grasses.

 spreading, scarcely subdivided ; spikelets of from ten to fifteen 

 crowded, elliptical, downy florets; awn us long as the glumes ; 

 leaves slightly hairy." Smith.
