48. Stink-grass (Eragrostis cilianensis; fig. 52). 



A slender, tufted, often decumbent annual ; leaves rolled in the bud ; collar 

 narrow, hairy; auricles none; lignle a fringe of hairs; sheaths glabrous,

dull, and sparsely hairy above, glossy 



slightly compressed ; blades flat, 



beneath, one-eighth inch wide. 



Stink-grass is very similar to slender meadow grass 

 except that the plants of stink-grass are about twice as 

 large as those of slender meadow grass. In most botan- 

 ical works this grass is called Eragrostis major. 



IDENTIFICATION OF SMALL-GRAIN 

 SEEDLINGS. 



The seedlings of small grains are, under 

 all conditions, very difficult to identify. 

 Men who are constantly growing these 

 grains usually learn to distinguish the 

 different species. Even certain varieties 

 in a species are sometimes recognizable. 

 But there is great variation even in the 

 different varieties, and the varietal differ- 

 ences in each species make it difficult to find 

 a combination of characters that will always 

 hold true for the species. 

 All of the small grains so far as studied have their leaves rolled 

 in the bud. The most dependable characters are found in the collar.
