Oats, Rice , Rye, Wheat . — The aleurone-layer is single. The 
aleurone-grains contain globoids both in this layer and in the cells of 
the embryo. In the embryo of the oat the distribution of the globoids 
may be taken as typical, and is well marked. The globoids are most 
numerous in the scutellum and in the periblem of the root : they are 
less abundant in the plerome of the latter, and absent from its 
epidermis. Oil occurs throughout the whole of the embryo and in 
the aleurone-layer in all four types. 
In the rice-seed minute starch-grains are found in the same cells as 
those in which aleurone-grains are so abundant — a somewhat ex- 
ceptional circumstance. 
Barley . — The aleurone-layer is not single, but for the most part 
several cells in thickness. In it each aleurone-grain has an envelope 
of proteid surrounding a single central globoid. In the embryo the 
globoids are small but very numerous. Their distribution in the root 
is sharply defined. The outermost three layers contain no globoids; 
the four succeeding layers are rich in them ; whilst the whole centre 
of the root is devoid of them.
