This is the true Squirrel-tail Grass of the Isle of Thanet, and not H. muri- 
num. In its short and stunted growth, from its maritime situation., the 
awns are rigid and strongly barbed, so as to be extremely troublesome 
to the mouths of horses when mixed Avith hay. Colonel Velley, who sent 
me the specimen, says it is very common all along the Kentish coast, 
from Sheppey Isle to the Isle of Thanet. If. murinum on the sea coast 
sometimes assumes the stunted habit of the true Squirrel-tail, but it 
wants the rigidity of that, and is not so strongly barbed.
