The habitat of this plant is moist meadows. The habit is erect, with round, hollow, stout, furrowed stems. The leaves are triangular, biternate, with 3 broad segments, divided into 3 lobes, 3 in. long. The leaflets are coarsely toothed, egg-shaped. The flowers are white, in large umbels with many rays. The fruit is oblong, with broad wings. There is no general involucre or whorl of leaflike organs, and no calyx teeth. The plant is 2-3 ft. high, flowering in July and August, being a herbaceous perennial.
The habitat of this plant is chalky fields, near limekilns, and it is introduced in ballast and cornfield weeds. The habit is erect, the stem being grooved, with angles, solid, and roughly hairy at the nodes. The leaves are twice pinnate, with lobes each side of a common stalk, the leaflets deeply divided, linear, with small segments. The flowers are pinkish-white, in terminal umbels, with 2-5 rays, and linear bracteoles or minute leaflike organs. The oblong fruit is 3-seeded, with long, smooth, hooked prickles in one row, borne on the secondary ridges. The plant is 6 in. to 1 1/2 ft. in height, flowering in July, and is a herbaceous annual.

Flower-stalks longer than leaf-stalks. Pods i-seeded, veined, kidney-shaped, black, flattened. Plant 6 in. to i ft. May August. Herbaceous annual or biennial. Fields and waste places; much cultivated as a fodder crop.

Differs from F. ovina as follows: - Taller, loosely tufted, stolo-niferous. Cauline leaves bristle-like or inrolled, blunt. Lower sheaths hairy. Panicle broad below, more or less 1-sided. Spikelets pale-red, 4-10-flowered. Awn short. 1-3 ft. June.
