Cereals. The cereal grains, all of which rank botanically as 

 grasses, are wheat, oats, barley, rye, rice, maize or Indian corn, 

 millet, and the less known sorghum, durra, or negro Guinea

 as a caryopsis. Its endocarpium, or inner membrane of the

 the most important part of the seed. 



The cereal grains contain the following proximate prin-
