Sweet-scented Yernal Grass (Anthoxanthum odo-

This is one of the earliest spring grasses, as well as 

 one of the latest in the autumn, and is almost the only 

 grass that is fragrant. It possesses a property said to 

 be peculiar to this species, or possessed by only a few 

 others, known as benzoic acid ; and it is said to be this 

 which not only gives it its own aromatic odor, but 

 imparts it to other grasses with which it is cured. The 

 green leaves when bruised give out this perfume to the 

 fingers, and the plant may thus be known. It possesses 

 but little value of itself, its nutritive properties being 

 slight; nor is it much relished by stock of any kind; but 

 as a pasture grass, with a large mixture of other species, 

 it is valuable for its early growth.
