Setaria, Beauvois. — The Bristle-Grass, having a compound almost cylin- 

 drical spike, derives its name from the Latin seta, a bristle. There are 

 three British species, yet perhaps better known under Linnaras's name of 

 Panicum. 



The "Rough Panick-Grass" of "Smith's English Botany." 

 Another doubtful British plant and interesting species, found 

 only in cultivated fields in the counties of Middlesex and 

 Norfolk, near London and Norwich. 



Native of France, Italy, Germany, Switzerland, Holland, 

 Belgium, North Africa, the United States of America, and Asia. 



Stem erect, bearing four or five flat, rough, lanceolate leaves, 

 with smooth striated sheaths, the upper one shorter than its 

 leaf. Ligule short and blunt. Joints four. Inflorescence simple- 

 panicled. Branches brief. Rachis rough. Spikelets dorsally
