LEGUMINOSAE (PULSE FAMILY) 251 Seed-time: August to October. Range: Locally established in Vermont and Ontario. Habitat: Fields, meadows, and waste places. This plant bears numerous flowers of charming color and fra- grance, and these pleasant traits may blind many eyes to other quali- ties that fit it to become a very noxious weed. The tough, slender rootstoeks bear many small tubers from which new plants are produced, and the plant also fruits abundantly above ground. It grows in dense mats, smothering all other plants that grow with it. Ordinary cul- tivation only serves to spread it by breaking the rootstoeks and scattering the tubers. Stems smooth, very slender, one to three feet long, with thin leaves and stipules; each pinnate leaf has but two oblong leaflets a little more than an inch long; petioles, slim and wiry, the tendrils hair-like and usually not branched. Racemes on very slender axillary pedun- cles, three- to six-flowered. Blossoms fragrant, not quite an inch long, with erect standard and obliquely spread rosy pink or reddish purple wings. Pods smooth, with globular, dark seeds, which, as forage, are dangerously un- WM%eJ^hyZs "tubero- wholesome. (Fig. 178.) sus). xi. Means of control Prevent seeding and check the growth of rootstoeks by close and persistent cutting throughout the growing season; then plow late in the fall, and in the next spring put the ground to a well-tilled hoed-crop, permitting no leaf-growth to the weed. A second sea- son of such root-starvation may be required, but increased returns from the crops repay the expense of extra Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resem
