Few plants, or then- synonyms, have been less understood by the 

 older botanists than this. Linnaeus had a specimen with a wrong 

 synonym, but knew nothing of its history, nor has he any where 

 described the species. It differs from all the foregoing in having 

 a strong, perennial, blackish root, and the ribs of'^the inner valve 

 of the corolla are finely downy, rather than fringed. These cha- 

 racters belong to Festuca more than to Bromus ; and if the seed 

 should prove entirely unconnected with the corolla, as I suspect, 

 it would confirm the relationship of the present plant to the 

 former genus. The numerous radical leaves are remarkable for 

 being very narrow, and fringed unequally with long, white, up- 

 right hairs ; those on the stem are broader, and nearly naked j 

 all of a fine deep green. Sheaths ribbed, mostly smooth ■ now 

 and then bearing a few hairs, intermixed with deflexed pube- 

 scence. Stipula very short, finally torn. The stem is 2 or 3 feet 

 high. Panicle erect and close, purplish, with yellow or saffron-
