232 LEGUMINOSAE (PULSE FAMILY) 



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.

The Sweet-clovers are natives of Central Asia but came to us 

 from Mediterranean Europe, where for centuries they have been 

 grown for forage and as honey plants. Weeds only when they are 

 permitted to make highways and by-places unsightly with thickets 

 of dying stalks. Their good qualities are many. First, they are
