T. durum, var. Valenciae, Korn. Handb. d. Getr. i. 72 (1885). 



Kornicke received this variety from Valencia, Spain, the Government of 

 Kharkov, Russia, and Chili. 



I have received it from Austria, Bulgaria, Asia Minor (Damascus), and the 

 Punjab, India ; also in samples of Goose wheat from Canada. 



Forms of this variety are rare and liable to be confused with examples of the 

 black-awned var. melanopus, in which the dark pigment does not develop in 

 some seasons. 



Flaksberger says that the forms from Russia should be placed under the 

 variety melanopus.
