The grains are a fine white tint, generally mealy, laterally compressed, 

 narrowed at the apex, with a prominent dorsal ridge or hump ; they are 

 7*5-8-5 mm. long, 3-3 mm. broad, and 3'5-3'6 mm. thick (Fig. 162).

T. pyramidale, var. recognitum, mihi. 



White Saidi (i, Fig. 163). An early wheat received 

 from Upper Egypt. 



This is a very distinct form, referred by Seringe 

 to T. durum complanatum and described by Delisle 

 (Descr. de I'Egypte, ii. 177) as T. sativum pyramidale. 

 Kornicke's T. compactum, var. recognitum, is probably 

 this form. 



In its habit and the morphological characters of its 

 leaves, it is quite unlike T. durum, T. sativum, or T. 

 compactum. 



Young shoots, erect ; young leaves pubescent, the 

 hairs slightly shorter in this than in most varieties of 

 T. dicoccum. 



Straw, short, 80-85 cm - (about 33 inches) high ; 

 upper internode hollow with thick pithy walls. 



Ear, short and very dense, 4-5-5 cm. long, 10-11 

 mm. across the face, 15-18 mm. across the side ; 

 spikelets 20-21, densely crowded on the rachis, many 

 with three grains in each; 0=45-50. Awns about 

 ii cm. long, scabrid to the base. The ear is flattish on one side and convex on 

 the other. It tapers from the base towards the apex, which in the larger ears is 

 often curved to one side. 



Empty glume, 8 mm. long ; apical tooth broad and blunt, i mm. long 

 (3, Fig. 161). 



Grain, mealy, dorsal hump very prominent ; 7-5 mm. long, 3-3 mm. broad, 

 3-65 mm. thick.
