Nonesuch.Medicago lupulina.Black Medick.
Found, from July to September, in dry soil and barren fields.
The little stalk, frequently about 6 inches high, is apt to lie upon the ground, and is zigzag or twisted in manner, or occasionally curving; it is slightly rough, and downy near the top. In color green, rusty, and pale near the top.
The parts of the 3-divided leaf are long-oval, broadest at the notched tip, which is further marked by the sharp little projection of the midrib beyond the slightly irregular margin; the surface is rough to the touch, downy when young; the color is a cool gray-green. The leaves, on slight stems, are arranged in groups alternately. A pair of sharp-pointed, notched wings clasp the stalk at the junction of the stem.
The small and delicate corolla is yellow; the minute calyx is green. The flower-head is small and round; on a slender terminal or side stem.
When the seeds ripen the pods swell large and bean-shaped; they turn dark, almost black, and are woolly to the touch; each contains one round seed.
