A pretty and very interesting yellow-flowered annual Clover, coming to us originally from Europe. The smooth, or slightly hairy erect or ascending stalk is very slender and leafy, and grows from six to eighteen inches in height. It is generally found along roadsides and in sandy fields, but my personal experience has found them in infrequent, isolated patches, along sparse thickets separating open woodland and fields, where the land was sloping and a little rocky. The three little leaflets of the compound leaf are shaped like the blades of miniature canoe paddles, with the rounding outer end indented or nicked. They are almost stemless, and as they ascend the lengthening stalk, they become a little larger and longer. They are thin textured, and the smooth surface is finely marked with feather veinings. Their margins are minutely scalloped by the tips of the veins, which extend to the edges and form tiny teeth. The slender thread of a stem upon which they are set, is guarded at its base with a pair of narrow pointed, clasping wings that are united with the stem centrally for half their length. The pleasing golden yellow flowering head is oval or oblong, and is densely crowded with very small florets, arranged alternately like scales. They are set on little stems held in the axil of the leaf. The florets are delicately fluted with the finest imaginable feather veins, and they open circularly from the lower tier, upward. As they mature, they turn downward like those of the Hop Vine, and become dry and husky, and retain a light golden brown colour. Several stalks spring from each root part, and they often form large, loose, widely spreading, brilliant green groups. Hop Clover is found from Nova Scotia to Virginia, west to western New York, Ontario, and Iowa, from May to September. The leaves of the Clovers have a family trait of drooping or closing together at night, as if to "sleep." The two lateral leaflets are drawn toward each other, and the third closes against their edges.
