Its greenish color readily distinguishes it from the seed of the culti- vated true clovers. Individual seeds vary consider- ably in form, since several are produced in each spiral pod. They are angular, oval-oblong or kidney- shaped and usually have a light stripe on each side. Yellow trefoil (Medicago lupulina). Fig. 216. This seed is largely used as an adulterant of red clover and alfalfa, and to some extent in alsike and crimson clovers. Individual seeds

This seed is largely used as an adulterant of red clover and alfalfa, and to some extent in alsike and crimson clovers. Individual seeds are practically the same size as those of red clover and alfalfa, but larger than alsike seed and smaller than average crimson clover seeds. The admixture of 35 to 45 per cent of this seed in red clover seed gives the latter in bulk a greenish tinge. It lightens the general color of alsike seed, but does not materially change that of alfalfa or crimson clover seed. Its detection is readily accomplished by examining in- dividual seeds with a lens. The seeds are produced singly in the pod and so are fairly constant in Fig. 216. Yellow trefoU, an adulterant. Fig. 217.
