CLUB, DWARF, CLUSTER, OR HEDGEHOG WHEAT 311 



The grains, which are white, yellowish, or red, are small, oval, narrow 

 towards the apex and plump, the cheeks right and 

 left of the shallow furrow usually well filled 

 (Fig. 192). In some forms they possess a prominent 

 dorsal hump similar to that found in T. turgidum. 



The endosperm in the majority of forms is opaque 

 and starchy, but in some it is flinty. 



In well-developed grains the breadth is usually 

 greater than the thickness.
