220 THE WHEAT PLANT 



Empty glume, 10-11 mm. long ; apical tooth acute, 1-5-2 mm. long (Form 9, 

 Fig. 138). 



Grain, flinty, long, narrow, 8-7-9 mm - l n > 4' mm - broad, 4-0 mm. thick. 

 Goose from Canada resembles this, but has smaller, narrower ears. 



4. Similar forms from Spain are Trigo Macolo, T. negro, with glabrous 

 leaves, and T. Enano de Larco, Trigo Eecio de Granada, T. Granadino and 



others with slightly scabrid young leaves. 



Forms with shorter and denser ears (7 cm. long, 15 mm. across the sides, 

 D = 33-36), and shorter grain, are also met with in Spain under various names. 



Ear bearded ; glumes -white, pubescent ; awns black ; grain red. 



T. durum, var. africanum, Korn. Handb. d. Getr. i. 73 (1885). 



Kornicke obtained this variety from Portugal, Egypt, and Asia Minor. 



A somewhat rare variety received from Spain, Portugal, Russia, and India. 



The Russian and Indian forms have long, somewhat narrow, square ears 

 (0 = 27-32), those from Spain and Portugal large, coarse, denser ears, showing 

 affinity with T. turgidum.
