COMMON BREAD WHEAT 275 



times irregularly arranged on the rachis, 3-grained ; = 21-25 (Ear type i, 

 Fig. 176). 



Empty glume, 10 mm. long ; apical tooth 2-3 mm. long (9, 14, Fig. 165). 



Grain, short, mealy, or semi-flinty, 6-1-6-5 mm. long, 3-2-3-5 mm. broad,

Roermaker and Ecksteen, with softer glumes, and pale yellowish-green 

 leaves, obtained from the Transvaal, are allied forms, probably derived originally 

 from India. 



It is almost impossible to grow any of these wheats in England on account 

 of their susceptibility to attacks of Yellow Rust (Puccinia glumarum).

 with plump spikelets and short, stiff awns 3-6 cm. long ; spikelets 15-18, plump, 

 2- to 3-grained ; D = 16-19 (^ ar tv P e 2 Fig. 174).

Empty glume, 9 mm. long, keeled to the base ; apex broad, lateral nerve 

 prominent ; apical tooth acute, 3-5 mm. long (6, 20, Fig. 165).

 broad, 3-5 mm. thick), were obtained from Tabriz and also from Turkestan.
