seldom more than one or two, possibly abortive spikelets, rough 

 with stiff hairs or teeth pointing downwards, which cling to the 

 hand or fingers as the spike is drawn downwards through them ; 

 hence the English name. 



Annual. Flowers in July, and thence often to the end of the 

 year. 



A common Grass in many parts of southern Europe, but 

 scarcely naturalized in England, owing its introduction thither to 

 accidental admixture of its seeds with those imported for agri- 

 cultural and gardening purposes. 



Setaria viridis. Green Bristle Grass. Plate LIII. 



Inflorescence spicate, continuous, cylindrical. Bristles of the 

 involucre rough with erect teeth. Lower, barren flower with a 

 single palea. Outer palea of the fruit nearly smooth. 



Setaria viridis, Beauvois. Most modern botanists. Panicum 

 viride, Linnceus. E.B. 875 ; ed. 2. 101. 



Found in similar habitats to the preceding species, which, indeed, 

 it often accompanies about London and Norwich ; but it is much 

 more distributed as to locality and station, though hitherto almost 

 exclusively confined to the south-eastern counties of England. 

 Stems one to two feet in height, smooth throughout, more gene- 

 rally erect than those of S. verticillata, the leaves being at the 

 same time broader and more succulent than in that species. Spike 

 two or three inches long, perfectly continuous, cylindrical, bluntly 

 attenuated at the apex, pale green or yellowish. Involucral bristles 

 many, rough, with minute teeth projecting at right angles or up- 

 wards, brown or reddish. 



Annual. Flowers in July, and until the end of autumn. 



This would be a valuable grass to sow in game preserves and 

 warrens, hares and rabbits feeding upon it with avidity. It will 

 flourish in the driest and poorest of light soils, indeed in almost 

 any medium, water and shifting sand excepted. The compara- 

 tively large seeds are easily collected ; and few plants are so prolific, 

 a single specimen in the garden having yielded 127 spikes during 

 the season. 



Setaria GLArcA. Glaucous Bristle Grass. Plate LIV. 



Inflorescence spicate, continuous, cylindrical. Bristles of the 

 involucre rough with ascending teeth. Lower, barren flower 

 triandrous with two palea;. Outer palea of the fruit transversely 

 wrinkled. 



Setaria glauca, Beauvois. Most modern botanists. Panicum 

 glaucum, Linnaus.
