CLASSIFICATION OF WHEAT 



Following the classifications of Carleton, 1 of Haeckel, 2 and 

 of Kornicke and Werner, and perfecting them by adding new 

 data, by extending to smaller subdivisions, by giving world dis- 

 tribution, and, for the sake of unity and completeness, by giv- 

 ing the essential characteristics of each division, there is given 

 below a descriptive and distributive outline of the division 

 Hordeae given on Page 2. 



1. 1 Hordeae (Sub-tribe) . 



2 . 1 Lolieae (Rye Grass) . 



3 I Leptureae. 



4-1 Elymeae (Barley Wild Rye). 



5.1 Triticeae 



1.2 Agropyrum (Genus) (Quack. G 

 2.2 Haynaldia. 

 3.2 Secale (Rye). 

 4.2 Triticum. 



1.3 Aegilops (section). Species ovafn taken as type. Pound in southern 



Europe to Turkestan in Asia. Twelve species in all are recognized. 

 2.3 Sitopyrus. 



1.4 Triticum monococcum. 



1.5 Name: None in English. German Einkorn preferred. French 



Engrain. 



2.5 Characteristics: Spikelets three flowered but one grained; hardy; 

 non-shattering : short , thin narrow-leaved plant , seldom over 3 feet 

 high. Very constant in fertility; does not give fertile cross with 

 common wheat; only species in which paleae fall in two parts at 

 maturity; spikelets awned; spike compact. 



3.5 Distribution: Found from Achaia in Greece to Mesopotamia. Present 

 in Swiss Lake dwellings of stone age. Cultivated to a limited extent 

 in Spain, France, Germany ; Switzerland and Italy. Unknown in 

 America except to experimenters. 



4.5 Varieties: Einkorn; Engrain double (two grains). 

 5.5 Use: Rarely for bread; usually for mush and "cracked wheat," and 



for fodder. 

 2.4 Triticum Polqnicum. 



1.5 Name: Polish wheat a misnomer; Giant or Jerusalem rye. Perhaps 



native in Mediterranean region. 



2.5 Characteristics: Only species in which lowest flower has palea as long 

 as its glume; outer glumes at least as long as flowering glumes; two 

 to three seeded; tall; stems pithy within; heads and kernels extremely 

 large; macaroni gluten; drought and. rust resistant; resembles rye.
