It is a tufted annual, bearing looser sheaths, narrower, 

 compressed spikes, and larger spikelets than does the 



Squirrel-tail Grass, but 

 its presence renders hay 

 fully as valueless since 

 the sharp awns, like 

 those of the more com- 

 mon species, penetrate 

 the flesh of sheep and 

 cattle, and occasionally cause 

 death. An English botanist 

 recorded his earlier achievements 

 science when he wrote of this 

 grass: " In our youth we put inverted 

 spikes of the Wall Barley up our sleeves 

 and found them travel to our shoulders, 

 is was caused by the parts of the spike- 

 3 being compressible, so that by a gentle 

 motion they progressed upward with a kind of 

 spring; but the barbs, on pulling the spike the 

 contrary way, stuck into the clothes and could 

 not easily be dislodged."
