wheat produces the flour from which macaroni is made, 

 its higher gluten content and greater density making it 

 superior for this purpose. It is a tall-growing sort, with 

 broad, smooth leaves and heavily bearded heads resem- 

 bling barley, with which it is often confused. The grains 

 are large with pointed ends, semi-transparent, and of 

 lower starch content than common wheat. Lyon states 

 that "the qualities that give value to durum wheat are its 

 ability to withstand drought and its resistance to rust."
