A single stalk grows to the height of 6 or 7 inches; it is smooth, round, and juicy; light green. The compound leaf is very deeply 3 times cut into long, narrow parts, with sharply notched edges; the texture is common (not to say coarse), and the color a full juicy green. Two or three leaves, on short foot-stems, grow in a whorl-like cluster about the stalk, a little below the flower-cluster. The flower has 4 rounded petals spreading at the top; in texture rather thick, in color white, faintly tinged with violet; the 4-parted calyx is pale green, and the 6 stamens, 2 noticeably shorter than the others, are a dull greenish-yellow. With the true vigor of its family this plant grows in small communities. It stays in bud a long time before the blossoms finally open. A number of small tubers are strung together on the roots, like beads on a necklace; pungent and peppery to the taste.

The single stalk, from 12 to 16 inches in height, is branching only for the flowers; it is large, fibrous, and strong, grooved, but very smooth, and of a shining, pure, green color. The lower leaves are 3 or 4 inches long, lyre-shaped, and cut nearly to the midrib into 5 or 7 irregular lobes, the middle lobe being very round; the upper leaves are cut less deeply, and are small; the margins are entire, the texture strong, and the lower surface rough, the upper being smooth and shining; in color, dark full green. The lowest leaves are on clasping stems, all the rest clasp the stalk with a pair of wings, alternately. The 4 petals of the small flower are rounding, and arranged in pairs within the small 4-parted green calyx; they are of a charming light yellow color, and so are the 6 stamens. These stamens group themselves oddly about the central pistil,--two pairs stand in front of the pairs of petals, and the single shorter stamens fill the more open spaces left in the opposite angles. The flowers form loose terminal groups. The stalk springs from a foot-rosette of the rich green leaves, and is one of the earliest risers of the spring, in its chosen home--a marshy meadow.

Va.).* Found in grain fields, and along cultivated lands, from July to September. The large and branching stalk is zigzag or curved in habit of growth, about 2 or 3 feet high, and ribbed; with occasional hairs; it is bright green in color.
