These are plants having somewhat the appearance and habit of growth of black medic, but have larger flowers, and produce straight, oblong, many-seeded pods. The basal leaflets have often been mistaken for stipules, which are rudimentary. They are characterized by growing in the driest situations and upon the lightest and most sterile soils. 247.

There are two to six yellow flowers in each cluster, the standard being tinged with red and green. The pods are 1 to 1.5 inches long. The seeds, about the size of red clover seeds, are oval, flattened on the sides, brown with a wide, round spot at the hilum.

Commercial seed is usually of the slender or Bird's-foot trefoil has become naturalized in this country, especially in the south.1 It is cultivated somewhat widely. although perhaps not extensively in Europe.

It is suitable either for cutting, or depasturing. It thrives almost on any soil, and is perennial. These properties render bird's-foot trefoil a very valuable plant for permanent pastures and meadows. It is also appropriate for shorter leys, where red clover does not thrive. The great obstacle to its cultivation is the ve...
