Yellow Clover.Trifolium agrarium.Hop Clover.
Found, during June and July, in dry fields and waysides.
The stalk branches slightly, and is leafy; it is slender, round, and smooth, and grows from 6 to 12 inches high. The color is light green.
The 3 leaflets of the compound leaf are long and narrow, with an exceedingly fine texture and smooth surface. The leaves, on very short stems, are placed in groups, or singly and alternately, upon the stalk; at the base of the stem, and uniting with it for half its length, occur a pair of enfolding wings.
The flowers are very small, and gathered into a close head, that is set on a little stem growing from the angle of a leaf; the corollas are yellow, the minute calices being green.
The flowers open from the bottom of the head upward, the mature blossoms becoming dry and husky, and turning down after the manner of the hop, as the bloom continues towards the summit; the heads thus show a harmonious gradation of color from brownish-yellow at the base, through yellow, to the yellow-green of the buds at the top of the head. The plant often grows in clumps of a considerable size.
