T. durum, var. leucomelan, Korn. Handb. d. Getr. i. 70 (1885). 



A common Mediterranean variety, especially frequent in Spain and Italy, 

 rare in Russia. Most forms have slightly rough young leaves ; they are probably 

 of hybrid origin and related to T. turgidum or T. vulgare. 



The majority possess somewhat short, solid straw ; stout, dense, short ears, 

 almost square in section, 7-8 cm. long, 12-15 mm. across the face and side.
