254 LEGUMINOSAE (PULSE FAMILY) 
Means of control 
Prevent seed production by hoe-cutting while small. Dormant 
seeds often germinate and bloom late, after horse cultivation of 
crops has ceased. Follow the cultivated crop with heavy seeding 
to clover or cowpeas. 
PINK WILD BEAN 
Strophostyles umbellata, Britton 
Native. Perennial. Propagates by seeds and by rootstocks. 
Time of bloom: July to September. 
Seed-time: August to October. 
Range: New York to Missouri, southward to Florida and Texas. 
Habitat: Moist, sandy soil; fields and waste places. 
More persistent and troublesome than the preceding species, 
because perennial. Stems often several from the same rootstock, 
two to five feet in length, very slender, branched, and trailing. 
Leaflets smaller and thinner in texture than the preceding species, 
sparsely hairy, long-ovate to oblong, usually somewhat obtuse at 
apex and rounded at base, entire, or rarely slightly lobed, the 
petioles generally shorter than the leaflets, with small, lance-shaped 
stipules. Flowers in umbellate heads on slender peduncles often 
three times as long as the leaves, with short pedicels, the corollas 
pink, fading yellowish, the standard about a half-inch broad. 
Pods one to two inches long, very slender, straight, slightly flat- 
tened, the seeds within closely packed, truncate at the ends, 
covered with a glandular mealiness. 
Means of control 
In cultivated fields, close and persistent hoe-cutting throughout 
the growing season, in order to prevent seed development and starve 
the rootstocks. Grazing off when in grasslands, particularly with 
sheep. 
SMALL WILD BEAN 
Strophostyles pauciflora, S. Wats. 
Other English names: Few-flowered Wild Bean. 
Native. Annual. Propagates by seeds. 
Time of bloom: July to September.
