The stalk is leafy and branching, large and tough-fibred, smooth, but grooved from the joints. The color is light yellow-green. The long leaf is narrow, and tapering to a slender point; it is somewhat fulled upon the taut midrib, and the margin is irregularly notched, while the surface is smooth. The color is a strong yellow-green, lighter on the wide midrib. The leaves are opposite each other, and partly grown together about the stalk. The small, tubular disc flower is dull tawny in color; the rays, usually 8 in number, are broad, and of a bright golden-yellow color. The large flower-heads are encircled by two rows of green, or greenish, bracts, the outer row being slightly twisted; they are somewhat nodding on short stems of equal length, and spring from the angles of the leaves. The seed, armed with 4 stout prongs, and plentifully set with backward-pointing bristles, is familiarly known as “beggars’ tick” or “stick-tight,”--it never loses a chance to catch a ride on the clothes of the unwary passer-by. Its smooth grooved stem, swelling at the joint, is an interesting feature of this otherwise rather coarse plant. [Illustration: BUR MARIGOLD: Bidens cernua.] *Rayless Marigold.* _Bidens frondosa._ Found in August and September, lying in wait for travellers along roadside ditches and in wet fields. The stalk, which grows any height from 2 to 6 feet, bears branches in pairs; is very leafy, and stout, round, coarse-fibred, and slightly shining. In color, purplish green. The leaf is divided into 3 or 5 lance-shaped parts; the margin is toothed, and the texture is coarse; it is set on short, ribbed-stems, and springs from a noticeable joint, in pairs, at regular intervals along the stalk, and branches. It is dull green in color. The flowers are very small, and ragged, of a dull tawny orange; they are crumpled tightly into a flat head, and sometimes partly surrounded by 1 to 3 inconspicuous, little, dull yellow, rays. The head is encircled by small, narrow, green, leaf-like parts of irregular lengths; it is set on a short green stem. Two or three heads are gathered in a terminal group. The cup-like joint of the leaf-stems is worth careful consideration, it is so neatly finished. The seed is dark and shining, and oppressively civil in its attentions to heedless wayfarers. [Illustration: RAYLESS MARIGOLD: B. frondosa.] *Wild Sunflower.* _Helianthus tuberosus._ *Jerusalem Artichoke.* Found through September and October, in cultivated fields, and along thicket borders. The stalk branches for flowers near the top; it is leafy, large, from 3 to 7 or 8 feet, very stout, and rough with short hairs. Its color is light green.
