254 THE WHEAT PLANT 



Young shoots, semi-erect ; young leaves pubescent. 



Straw, tall, 125-130 cm. (about 50 inches) high, hollow with thick walls. The 

 plants tiller very little, each usually sending up not more than two straws. 



Ears, 8-9 cm. long, varying in width according to the amount of branching. 



In a typical ear (i, Fig. 160), which is generally less compound than var. 

 mirabile (p. 256), the upper third is normal, bearing single spikelets at each 

 notch of the rachis. At each notch of the middle third of the ear two spikelets 

 arise, side by side, arranged at right angles to the spikelets above ; the notches 

 of the lower part of the ear bear short secondary ears, 2-2-5 cm - l n g> usually 

 composed of 3-7 spikelets. A well-grown ear possesses 60-70 spikelets, yielding 

 90-100 small grains. 



Empty glume, pale red, 6 mm. long ; apical tooth very short and blunt ; awns 

 of the flowering glume 2-5-7 cm. long (9, Fig. 152). 



Grain, small, semi-flinty, laterally compressed, with narrow apex ; 6-7 mm. 

 long, 3-5 mm. broad, 3-55 mm. thick. 



A form of pseudocervinum is recorded by Kornicke and Werner from Castile 

 Spain, under the name Trigo Rubio ; they state that it is sometimes cultivated 

 in Southern Europe and Northern Africa. 



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



T. turgidum, var. speciosum, Kdrn. Handb. d. Getr. i. 60 (1885). 



A fairly common variety cultivated in Italy and France. Flaksberger 

 records its occurrence from the Tiflis and Baku Provinces of Transcaucasia, 

 and notes that pure lines of the typical red-awned variety sometimes give black- 

 awned forms (var. Mertensii). 



1 . A winter form from Spain. 



Young shoots, prostrate or semi-erect ; young leaves pubescent ; hairs short. 



Straw, tall, 122 cm. (about 48 inches) high ; upper internode solid. 



Ear, lax, 9-10 cm. long, compressed, the face broader than the side as in 

 T. vulgare, 12-15 mm. across the face, 10-11 mm. across the 2-rowed side; 

 spikelets 21-23, broad, 3- to 4-grained ; = 23-25 ; awns 15 cm. long. 



Empty glume, 9 mm. long, narrow, apical tooth acute. 



Grain, flinty, narrow, dorsal ridge prominent ; 7-8-7-9 mm. long, 3-7-3-9 mm. 

 broad, 3-8-4 mm. thick. 



2. Mazzochio. A form grown extensively in Italy (Tuscany). 

 Young shoots, semi-erect ; young leaves pubescent. 



Straw, very tall, somewhat slender, 157 cm. (about 62 inches) high; upper 

 internode solid. 



Ear, 8-9 cm. long, square, 11-13 mm. across the sides, or slightly compressed, 

 10 mm. across the face and 12-14 mm. across the side ; spikelets 22-25, 2 " to 3" 

 grained ; D = about 30 ; awns stout, 12-15 cm. long, deciduous (Ear types i, 2, 



Fig- 157). 



Empty glume, 6-7 mm. long, apical tooth very short, blunt (3, 6, Fig. 152). 



Grain, mealy, large, yellowish-red, dorsal ridge prominent ; 8-2 mm. long, 

 4-5 mm. broad, 4 mm. thick.
