Fig. 164. - Yellow or Hop Clover (Trifolium agra-rium). X 1/3.

Seed-time: June to October.

Range: Throughout the United States and southern British America.

Habitat: Fields, roadsides, and waste places.

Still more weedy and valueless than the preceding species, mature plants in dry and exposed situations sometimes becoming tumble-weeds. Stems many from the same root, slender, finely ridged, hairy, weak and reclining, three to ten inches long. Leaves small with short petioles, and broadly ovate, pointed, cohering stipules; leaflets short, wedge-shaped at base, rounded truncate or notched at the apex, shorter than those of the preceding species, and differing also in having the lateral ones sessile but the terminal one on a distinct foot-stalk. Heads globose, scarcely more than a third of an inch in diameter, and lifted much above the leaves on slender, axillary peduncles; corolla bright yellow, the standard broader than long, spreading, and persistent, becoming reflexed, and turning brown, exceeding and covering the small, one-seeded pod.

Means Of Control

Graze off with sheep, so preventing seed development. Put the land under cultivation and reseed heavily with larger and better plants of the Clover Family.
