This grass, as has already been remarked, produces a 
fine early foliage in the spring. The produce is very 
great, and its nutritive powers are considerable. It appears, 
from the above particulars, to be best adapted for hay. A 
very singular disease attacks, and sometimes nearly de- 
stroys the seed of this grass : the cause of this disease 
seems to be unknown ; it is denominated Clavus by some ; 
it appears by the seed swelling to three times its usual size 
in length and thickness, and the want of the carcle. Dr. 
Willdenow describes two distinct species of it : 1st, the 
simple clavus, which is mealy and of a dark colour, with- 
out any smell or taste ; 2dly, the malignant clavus, which 
is violet blue, or blackish, and internally too has a blueish 
colour, a foetid smell, and a sharp pungent taste. Bread 
made from grain affected with this last species, is of a 
blueish colour ; when eaten, produces cramps and giddiness.

The proportional value which the grass, at the time of 
flowering, bears to that at the time the seed is ripe, is as 
6 to 14 . 
This species greatly resembles the preceding in habit 
and manner of growth, but is inferior to it in value, 
or lbs. per acre.
