Fig. 11.—Mixture of seeds of awnless brome-grass (a), meadow fescue (b), Eng- lish rye-grass (c), and chess, or cheat (il). The brome-grass seeds are dis- tinguished by their greater length and flattened form. The seeds of chess (d) are somewhat cylindrical, due to being folded lengthwise. They are thus thicker than the awnless brome-grass seed and sometimes are awned. (En- larged.) varieties of a kind as a rule can not be distinguished in this way. For example, red clover

Fig. 11.—Mixture of seeds of awnless brome-grass (a), meadow fescue (b), Eng- lish rye-grass (c), and chess, or cheat (il). The brome-grass seeds are dis- tinguished by their greater length and flattened form. The seeds of chess (d) are somewhat cylindrical, due to being folded lengthwise. They are thus thicker than the awnless brome-grass seed and sometimes are awned. (En- larged.) varieties of a kind as a rule can not be distinguished in this way. For example, red clover seed can be distinguished from other seeds, but the medium and mammoth varieties of red clover can not be distinguished by their seeds. Seeds of varieties of individual kinds of plants usually must be grown to insure vari- etal determination. This is not a part of the usual seed test. The first object of the test, excepting with respect to va- rieties, is to find out if the seed is true to name. « The seed of certain farm crops is rarely free from all impurities. Miscellaneous im- purities may appear or some one kind of foreign seed may be present as an adulterant. Old seed of the same kind as the crop seed may constitute an adulterant, a fact which becomes apparent in the germination ^ -^.^^^J a Fig. 12.—Seeds of flax dodder (b double, c single) and of flax (a), showing relative sizes.
