Rye 



The grain of Secale cereale L., of the grass family, native 

 of southern Europe and central Asia, and cultivated in all 

 temperate regions. It is usually grown as a winter annual, 

 that is, planted in the late summer, allowed to rest during 

 the winter, and mature the next summer. Thus grown, 

 it is known as "winter rye." When planted in the spring 

 and harvested the same season it is called "spring rye." 

 There are a number of varieties specially adapted to each 

 of these modes of culture.

Wheat 



The ordinary wheat of commerce is the grain of Triticum 

 sativum L., of the grass family, native of the Mediterranean 

 region and cultivated in all temperate regions. It presents 

 a number of quite distinct forms or separate species, with 

 different useful properties and grown for different purposes. 

 Of each of these races there are many cultivated varieties, 

 produced by selection and breeding, and by hybridization. 



Besides the above, there are two distinct species, T. 

 monococcum L. and T. polonicum L., which are cultivated 

 to a very small extent. 



Ordinary wheat is mostly grown as a winter annual, 

 "winter wheat," but also largely as "spring wheat." 

 (See explanation under rye.) 



Wheat in its original form possesses long awns to its 

 glumes, commonly called the "beard," which are very
