Weeds. 420 COMPOSITAE (.COMPOSITE FAMILY). Fig. 292. — False Boneset (Kuhnia eu- patorioides). X J. pappus of numerous long and very plumy hairs, yellowish to nearly white. (Fig". 292.) A near relative of the preceding plant, the Pkairie False Boneset (Kuhnia gluti- ndsa, Ell.) ranges from Illinois to the Dakotas and southward to Alabama and Texas. It is similar in habit and in season of bloom and fruitage, but is taller and stouter, more hairy, and has foliage somewhat viscid or sticky as well as resinous. Its pappus plumes are tawny brown. Means of control Prevent seed formation by cutting when in first bloom. Cultivation of the soil will kill the perennial roots, but, where that is not desirable, frequent hoe-cutting and salt- ing will starve them. Or the plants may be hand-pulled when the ground is soft, the single taproot making the process easy. BROAD-LEAVED GUM PLANT GrindMia squarrdsa, Dunal Other English names: Gumweed, Scaly Grindelia. Native. Perennial. Prop'agates by seeds. Time of bloom: June to September. Seed-time: July to October.

This weed was formerly common only on the western prairies, but unrestricted exchange of commercial seeds has carried it into many of the Eastern States as an impurity of grass seeds and grain. It is very persistent when established in meadow lands and is a serious injury to the crop. The leaves and flowering tops of the weed are official in the United States Pharmacopoeia, and, if collected when the flowers are just coming into full bloom and.
