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 paucifldra, S. Wats. 



Other English names: Few-flowered Wild Bean. 

 Native. Annual. Propagates by seeds. 

 Time of bloom : July to September.
