CULTIVATED BARLEYS 



sides of the furrow line and very closely resemble the grains of 

 the two-rowed races. 



(ii) The broad erect-eared barleys, such as Goldthorpe, Im- 

 perial, AVcbb's Beardless, and Jewel, are easily recognised by the 

 presence of a small deep transverse furrow across the base of the 

 grain, below which is also a distinct rounded lump (4, Fig. 162). 



The rachilla lying in the longitudinal furrow at the back of the 

 grain is short and usually bears a number of long thin straight 

 hairs (3, Fig. 163): in some varieties of this class, however, the 

 rachilla is woolly, like i, Fig. 163.

(iii) The narrow bent-eared barleys have neither transverse 

 furrow nor lump at the base of the grain, but slope off as at 2, 

 Fig. 162. Those belonging to the Chevalier stock have a rachilla 

 which is covered with short \\a\\ wool-like hairs (i. Fig. 163). 



The rachilla of the Old Common, Nottingham long-ear, and 

 so-called ' Prolific ' but inferior malting barleys is longer and the 

 straight hairs shorter than on the rachilla of the erect-eared 

 barleys (2, Fig. 163).
