3 o6 THE WHEAT PLANT 



long, and short incurved awns; spikelets 14-20; = 20-25; empty glume 

 inflated, yellow or yellow-blackish with dark brownish-black margins and 

 reddish grain, and (2) a winter form, var. triste, and with lax tapering ears (in 

 Bull. App. Bot. viii. 194, he states the grains of var. triste are white). 



Ear beardless ; glumes bluish-black ; grain red. 



T. vulgare, var. cyanothrix, Korn. Handb. d. Getr. i. 46 (1885). 

 A very rare variety represented only by one or two forms. 



1 . Blue Velvet Chaff. A winter late form received from Germany (Haage 

 and Schmidt). The bluish colour of the empty glumes is absent in some 

 seasons, the ear being then a foxy-red tint. 



Young shoots, prostrate. 



Straw, stout, tall, 127-140 cm. (50-55 inches) high ; glaucous. 



Ear, tapering, 10-13 cm. long, spikelets 26-28; D = 22-24 (Ear type 2, 

 Fig. 187). 



Empty glume, 9-10 mm. long, apex narrow ; apical tooth blunt (14, Fig. 166) ; 

 flowering glumes of the upper spikelets with awns 10-12 mm. long. 



Grain, flinty, apex somewhat truncate ; 6-8 mm. long, 3-85 mm. broad, 3 mm. 

 thick. 



2. A somewhat similar but earlier form received from Persia. 

 Young shoots, semi-erect. 



Straw, stout, tall, very glaucous. 



Ear, 8-10 cm. long, square, 10 mm. across the sides or 12 mm. across the 

 face, and 10 mm. across the 2-rowed side ; spikelets 18-20 ; D = 20 (Ear type 2, 

 Fig. 187). 



Empty glume, 9-10 mm. long, apex truncate ; apical tooth blunt (10, n, Fig. 

 1 66) ; upper half bluish-black, lower half yellow, in some seasons all yellowish ; 

 flowering glumes of the upper spikelets with awns 10-12 mm. long. 



Grain, large, semi-flinty, 7-7-5 mm. long, 3-9 mm. broad, 3-5 mm. thick. 



Ear beardless ; glumes black, pubescent. 



T. vulgare, var. nigrum, Korn. Handb. d. Gert. i. 46 (1885). 



This variety was only known to Kornicke through Seringe, who refers to it 

 in his Cereales europeennes (p. 139) as "Variation N. Touzelle Lammas (noire 

 veloutee)."
