Straw, very tall, slender, 130-140 cm. (about 52-56 inches) high. 



Ear, 10-12 cm. long, almost square in section, 10-11 mm. across the face 

 and side, with divergent awns 8-10 cm. long ; spikelets 22-25, 3-grained ;

T. vulgare, var. erythrospermum, Korn. Syst. Uebers. n (1873). 



This is one of the most widely distributed varieties of T. vulgare, forms of 

 it being found in almost all countries where wheat is cultivated. It is grown 

 more especially in regions having cold winters and hot summers. 



Of the 250 examples collected from various parts of the world the majority 

 came from Russia, Roumania, Hungary, Spain, India, and the United States, 

 but a few were received also from Asia Minor, Persia, China, Japan, Manchuria, 

 Morocco, South Africa, Argentina, Australia, Portugal, Austria, Germany, 

 Holland, France, and England. 



The greatest number are Spring and Winter wheats with lax, compressed ears. 

 With the exception of one or two prolific, bearded, Squarehead wheats they give 

 poor yields of grain, although the baking quality of their flour is generally 

 excellent.
