CLUB, DWARF, CLUSTER, OR HEDGEHOG WHEAT 319 



Ear beardless ; glumes red, pubescent ; grain white. 



T. compactum, var. crassiceps, Korn. Handb. d. Getr. i. 53 (1885). 



Kornicke's type was of hybrid origin. 



I obtained an exceptionally early form of it in a sample of Walla Walla wheat 

 from the United States. Its ears appear about the end of May at Reading and 

 ripen about the last week in July. 



Young shoots, erect. 



Straw, tall, 130-142 cm. (51-56 inches) high, somewhat slender, hollow. 

 In the early stages of growth the leaves, straw, and ears are of a yellowish grass- 

 green tint. 



Ear, 4-5-5 cm. long, square, 12-15 mm. across the face and side ; spikelets 

 18-20 ; 0=42-45 (Ear type I, Fig. 200). 



Empty glume, 7 mm. long, apical tooth blunt, i mm. long (9, Fig. 191) 



Grain, flinty, 5-6-5-9 mm. long, 3-2-3-6 mm. broad, 3 mm. thick. 



Ear beardless ; glumes red, pubescent ; grain red. 



T. compactum, var. rubrum, Korn. Handb. d. Getr. i. 53 (1885). 



A glaucous-eared form received in a sample of Walla Walla wheat from the 

 United States. 



Young shoots, prostrate. 



Straw, tall, 130 cm. (51 inches) high, stout, hollow, pink when unripe. 



Ear, 5-6 cm. long, 12 mm. across the face, 12-15 mm. across the side > 

 spikelets 20-22 ; D =40-42 (Ear type 2, Fig. 200). 



Empty glume, 7 mm. long, narrow at apex ; apical tooth blunt, i mm. long 

 (9, Fig. 191). 



Grain, flinty, 6-2-6-4 mm. long, 3-2-3-6 mm. broad, 3-15 mm. thick. 



A short, dense-eared form of this variety with grass-green leaves and ears 

 4-4-5 cm. long (D =48-50) was obtained among the progeny of a " clubbed " ear 

 of T. vulgare (var. milturum) from Chungking, China (2, Fig. 200). 



Ear beardless ; glumes bluish-red, pubescent ; grain red. 



T. compactum, var. clavatum, Korn. Handb. d. Getr. i. 53 (1885). 



Kornicke states that the type of this variety received by him from Hohenheim 

 has somewhat elongated narrow ears, slightly awned at the tip, with blue-black 

 glumes on a reddish ground like those of T. turgidum, var. dinurum (p. 257). 



Ear beardless ; glumes blue-black, pubescent ; grain red. 



T. compactum, var. atrum, Korn. Archiv f. Biontologie, ii. 398 (1908). 



Kornicke's type with more or less quadrangular ears was derived from 

 specimens shown in 1883 in an Agricultural Exhibition by Bestehorn, who 

 crossed various wheats ; this variety was apparently the result of crossing some 

 form of T. compactum with T. turgidum, var. iodurum. 



A glaucous form received in a sample of Walla Walla wheat from the United 

 States. 



Young shoots, prostrate.
