A comparatively rare variety, the type of which was obtained by Kornicke 

 from a sample of " Grano tenere bianco," sent by G. Salomone from Catania, 

 Sicily, to the Vienna Exhibition in 1873. 



A short dense-eared wheat from Baluchistan has been referred to this variety 

 by Howard. 



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



T. turgidum Dreischianum, Korn. Handb. d. Getr. i. 60 (1885). 



Kornicke's type was sent to him under the name " Frumento bianco " by 

 Dr. Dreisch from the Italian Exhibition held in Paris in 1878. This variety is 

 chiefly confined to the Balkan area, most examples being received from Greece, 

 Bulgaria, and Turkey. 



A winter form from Greece, Bulgaria, and Turkey. 



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



Straw, tall, 130 cm. (about 52 inches) high, hollow with thick walls. 



Ear, 9-11 cm. long, lax, narrow, square, 10-11 mm. across the sides ; spike- 

 lets 22-24, somewhat elongated, 2- to 3-grained ; = 22-24 '> awns about 13-14 

 cm. long, parallel to the sides of the ear (Ear type 2, Fig. 156). 



Empty glume, 9 mm. long, apex narrow, apical tooth very short and blunt (3, 

 6, Fig. 152).

T. turgidum, var. pseudocervinum, Korn. Handb. d. Getr. i. 63 (1885). 



This is one of the most frequently cultivated varieties with compound ears, 

 and may be considered as var. Dreischianum with a branched rachis. 



I have received examples from Turkey under the name Keupely, from 

 Idaho and other parts of the United States as Alaska, Seven-headed, and 

 Miracle wheat, and from Greece.
