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). 4.
