The specific characters of this species are much the same 
as those of the Poa fertilise differing in the compressed 
figure of the straws, and creeping root only. If the pro- 
duce was of magnitude, it would be one of the most valuable 
grasses ; for it produces foliage early in the spring, and 
possesses strong nutritive powers.
