*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.

The slender, branching stalk varies from 4 to 10 inches in height, and is smooth, or slightly rough, and light green. The leaf has 3 long, narrow, and blunt-pointed leaflets,--their midribs conspicuous to the very tips; the margin is entire, the texture fine and downy to the touch, and the color is a rather light green. The leaves, on short stems, are arranged alternately and near together. The small, greenish-white corolla is shorter than the calyx, which is long, and green, with 5 feathery tips that are rose colored and give to the head its peculiar gray-pink hue. The flower-heads are oblong; 2 or more are found on a branch. A faint perfume belongs to the newly opened flowers. Doubtless the children’s name, “Pussy Plant,” points to the resemblance the silky, green-rose head bears to the pussy-willow catkins. [Illustration: STONE CLOVER: T. arvense.] *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.
