MACARONI WHEAT 225 



Empty glume, oval, very broad, 9 mm. long, 4 mm. wide (9, 12, Fig. 138). 

 Grain, flinty, 7-7-5 mm. long, 3 mm. broad, 3 mm. thick. 



Ear bearded ; glumes red, glabrous ; awns black ; grain red. 



T. durum, var. alexandrinum, Korn. Handb. d. Getr. i. 71 (1885). 



Kornicke's type was obtained from Lower Egypt through L. Wittmack. A 

 comparatively rare variety which I have received only from Spain and the 

 Canary Isles. 



1. Trigo bascunano from Spain. 



Young shoots, erect ; young leaves glabrous or slightly rough. 



Straw, tall, 127 cm. (50 inches) high ; upper internode solid. 



Ear, dense, 7-8 cm. long, 10-12 mm. across the face, 13-16 mm. across the 

 side ; spikelets 22-23, 2 ~ to 3~K n ^ nc ^ \ D = 33-35 ; awns 15-17 cm. long (Ear 

 type i. Fig. 144). 



Empty glume, 9-10 mm. long ; apical tooth slightly curved, acute, i mm. 

 long (9, Fig. 138). 



Grain, semi-flinty, 8-25 mm. long, 3-65 mm. broad, 3-8 mm. thick. 



Allied to this arc short-eared forms from the Canary Isles and a long-cared 

 form (ears 9-10 cm. long and D = 28-30). 



2. Spanish Form. 



Young shoots, erect ; young leaves glabrous or slightly rough. 



Straw, of medium height, 90 cm. (about 35 inches) high ; upper internode 

 hollow. 



Ear, short, dense, 6-8 cm. long, square, 10-12 mm. across the sides or slightly 

 compressed; spikelets 20-24, 3* l " 4 -grained ; I) 30; awns divergent, 12- 

 13 cm. long (Ear type i, Fig. 144). 



Empty glume , 9-10 mm. long, keel and outer edge often black ; apical tooth 

 acute, 1-5-2 mm. long (9, Fig. 138). 



Grain, flinty, 8 mm. long, 3-3-5 mm. broad, 3-3-5 mm. thick. 



Ear bearded ; glumes red, pubescent ; atcns red ; grain tchitr. 



T. durum, var. italicum, Korn. ILtndb. d. Getr. i. 73 (1885). 



Kornicke obtained this variety from Italy, Spain (Murcia and Valencia), 

 Greece, and Egypt. 



Forms of var. upulicum in some seasons do not develop the black colour in 

 the awns and may often be placed under this variety. All the forms I have seen 

 of this variety exhibit characters which suggest affinity with T. tur^idum or T. 

 vulgare. 



Trigo Sicilian!. Received from Italy. 



This form is not typical of T. durum ; the characters of leaves, ears, straw, 

 and grain suggest an affinity with T. turgidum. 



Young shoots, semi-erect ; young leaves pubescent. 



Stnm\ of medium height, 90 cm. (about 36 inches) high; upper internode solid. 



Ear, large, 9-11 cm. long, square, 11-13 nun. across the sides; spikelets
