232 LEGUMINOSAE (PULSE FAMILY). 
Seed-time: June to October. en i 
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.

The Sweet-clovers are natives of Central Asia but came to us 
from Mediterranean Europe, where for centuries they have been
