This and the preceding species are strictly annual, and 
from the results of this trial, their nutritive powers ap- 
pear to be very inconsiderable. The seed of this species, 
Mr. Schreber describes (in Beschreibung der Graser) as the 
manna grass. In Poland, Lithuania, &c. it is collected in 
great abundance, when, after being thoroughly separated 
from the husks, it is fit for use. When boiled with milk, 
or wine, it forms an extremely palatable food, and is most 
commonly made use of whole, in the manner of sago, to 
which it is in general preferred.
