COMMON BREAD WHEAT 297

 Fig. 180 ; i, Fig. 181). 



Empty glume, thin, 9 mm. long, narrow at apex ; apical tooth acute, 1-2 mm. 

 long ; flowering glumes often have slender awns 5-10 mm. long (23, Fig. 166). 



Grain, flinty, apex truncate, 6-6 mm. long, 3-65 mm. broad, 3 mm. thick. 



A similar early form with somewhat denser semi-bearded ears (D = 2i,

 South Africa, under the name Wit Wol Koren. 



2. A spring form received from Persia under the name G-andum Kamisheh. 

 Young shoots, erect. 



Straw, slender ; leaves glaucous. 



Ear, lax, 9-10 cm. long; spikelets 17, inflated; = 19 (Ear type i, Fig. 



179)- 



Empty glumes, oval, 9 mm. long ; apical tooth curved, slender, 1-3 mm. 



long ; flowering glumes of upper spikelets with tortuose awns 1-2-5 cm - l n 

 (Form 3, Fig. 166). 



Grain, long, semi-opaque, with highly arched dorsal side ; 7-8 mm. long,

 Young shoots, prostrate. 



Straw, tall, 112-118 cm. (44-47 inches) high.

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

Grain, short, plump, semi-flinty; 5-8 mm. long, 3-65 mm. broad, 3-0 mm. 

 thick. 



Closely similar are Snowdrop and Velvet Chaff, also from New Zealand, 

 and Pudel wheat from Sweden. 



4. Blanc a duvet from France is a winter form similar to Pearl in the length 

 of its ear and straw and in the habit of its shoots, but possesses a somewhat 

 narrower empty glume 10 mm. long, the apical tooth 1-1-5 mm. long (15, Fig. 

 166), and a more elongated flinty grain 6-15 mm. long, 3-5 mm. broad, 3-0 mm.

The English Old Hoary, Essex Rough Chaff, and Velvet Chaff White, 

 which were formerly much grown in this country, closely resemble this form. 



5. Early spring forms with erect young shoots, narrow tapering ears 9-10 

 cm. long, 0=23-25, and grain 6-5 mm. long, 3-65 mm. broad, 3-55 mm. thick 

 have been obtained from Rhodesia, Australia, and New Zealand. They come'
