 node solid or hollow with thick walls. 



Ear, slightly tapering towards the apex, 8-9 cm. long, almost square, 11-13 

 mm. across the sides ; spikelets 19-20 ; = 30-34 ; awns 18 cm. long, slightly 

 divergent (Ear type i, Fig. 143). 



Empty glume, black, with a bluish-white surface, 9 mm. long ; apical tooth

Grain, flinty, compressed, with high dorsal ridge, apex truncate, 8-2 mm. 

 long, 3-65 mm. broad, 3-9 mm. thick. 



A closely similar form to this from Bulgaria has ears 7-9 cm. long, almost 

 square, 10-12 mm. across the sides, or compressed, 10 mm. across the face, and 

 13 mm. across the sides.

T. durum, var. australe, mihi. 



Huguenot or Bald Medeah (2, Fig. 146). Received from Australia, where 

 it is grown as a hay crop and for green feed in the coastal regions. 



At Reading it is very early, coming into ear before the end of May. 



Guthrie states that it originated from a single plant with two beardless heads 

 in a crop of Medeah (var. erythromelan, p. 224). The selection was made in 

 1897 by J. Correll, Arthur River, Western Australia. G. L. Sutton notes that 

 the original plant is supposed to have been a natural cross between Medeah and 

 Purple straw ( T. vulgare, var. lutescens). 



Young shoots, erect. 



Straw, stiff, erect, tall, 127 cm. (about 50 inches) high ; upper internode solid 

 and often wavy below the ear. 



Ear, dense, 6-5-7 cm. long, tapering towards apex and bases, 9-10 mm. 

 across the face, 15 mm. across the side ; spikelets 22-24, 3~grained ; D = 38. 



Empty glume, 9-10 mm. long; apical tooth small, very short, -5 mm. long; 

 secondary tooth of empty glume distinct (14, Fig. 138). 



Grain, flinty, with high dorsal ridge and bluntish apex ; 7-8 mm. long, 3-5 

 mm. broad, 3-5 mm. thick. 



Ear beardless ; glumes red, glabrous ; grain white. 

 T. durum, var. sub-australe, mihi. 



Received from Australia in a sample of Bald Medeah (the previous variety), 

 with which form it agrees in all respects except in the colour of the glumes.
