are formed so early in spring that this is usually 



the first grass to be noticed in flower, its only rival 



in this respect being 



Meadow Foxtail. The 



whole plant when cut 



smells strongly of cou- 



marin, theessential oil 



to which the smell of 



new mown hay is due. 



The hay like smell can 



usually be observed by 



chewing the grass, and
