This species is pretty generally cultivated in many parts 
of this kingdom ; and it appears from the above details to 
be a valuable grass, though inferior to many others.

The nutritive powers of the straws and leaves are, there- 
fore, more than twice as great as those of the flowers. This 
species, being strictly annual, is of comparatively little 
value. The above particulars show that it has very consider- 
able nutritive powers, more than its name would imply, if 
taken at the time of flowering ; but if left till the seed be 
ripe, it is like all other annuals, comparatively of no value.
