 the prominent nerve on the outer half ends in a distinct second- 

 ary tooth some distince from the apical tooth. 



Palet, divided longitudinally to the base when the ear is 

 ripe.

 spikelet, large and frequently fertile; rachis very fragile, 

 usually fringed along the margin with long straight hairs. 



Empty glume, long narrow, keeled to the base; apical 

 tooth blunt or acute ; the strong nerve on the outer half con- 

 verging towards the base of the apical tooth and ending in a

Grain, very long (9-12 mm.), narrow and flinty, somewhat 

 triangular in section, with a conspicuous tuft of white hairs 

 at the apex. 



Race IT. — Triticum dicoccum , Schiibl. Emmor. Coleop-

 European Emmers 2-nerved.
