THE SMALL GRAINS 



lemma, glabrous, rough toward the apex, thin mem- 

 branous 2-keeled, the keels bearing many short cilia; 



stamens 3, anthers 

 4 mm. long, some- 

 what narrow, yellow, 

 emarginate at base 

 and apex, attached 

 to filament in the 

 middle ; reproduc- 

 tive organs similar to 

 those of wheat (35) 

 (Fig. 29). 



84. Kernels. 

 Except in the hull- 

 ess group, the kernel 

 at the time of ripen- 

 ing is tightly inclosed 

 by the lemma and 

 palea, the first form- 

 ing what is com- 

 monly called the 

 hull, but which is 

 very different from 

 the thin hull or 

 bran of the wheat 

 The kernel 

 is usually 

 cylindrical, 

 but varies in length 

 and shape; and is very hairy ; light yellow, in the hulless 

 group yellowish brown; bran thin and tender. 



The proportion of caryopsis or kernel proper to hull, 

 and the hardness and length of the latter are of corn- 



kernel.

 showing both kernels, and twisted awns, almost 

 and the absence of basal bristles.
