ant in N. America ; in Chili only in S. America. 

 The most valuable German, American, and 

 Hungarian kinds belong to this variety. It is 

 cultivated either as a summer or winter grain. 

 Tr. sat. compactum (Tr. compactum Host.), 

 " Dwarf Wheat," " Hedgehog Wheat." Spikes 

 3-4 times longer than broad, awned or awn- 

 less ; culms and spikes very rigidly upright. 

 A very old cultivated form (Lake dwellings of 

 Robenhausen ! ) at present mainly cultivated 

 in the Austrian Alps, Wiirtemberg, Alsace, 

 Switzerland, Chili, and Turkestan. The awned 

 kinds are call- 

 ed " Hedgehog 

 Wheat." The 

 Abyssinian 

 " Dwarf Wheat" 

 forms a special 

 group. On ac- 

 count of their 

 stiff culms the 

 dwarf wheats 

 are less liable to 

 lodge. Certain 

 kinds, like the 

 yellow winter 

 Hedgehog wheat, 

 are peculiarly 

 adapted to rough 

 and stormy re- 

 gions. The yel- 

 low summer 

 Hedgehog wheat 

 is also profitable 

 on poor soils.
