. A manual of weeds : with descriptions of all the most pernicious and troublesome plants in the United States and Canada, their habits of growth and distribution, with methods of control . Weeds. 398 RVBIACEAE {MADDER FAMILY) Stems many-branched, ridged, and square, two to five feet long, very slender and too weak to support themselves, so that they clamber over other plants, clinging by means of backward-turning prickles on the stem angles. Leaves in whorls of sixes or eights, one to two inches long, narrowly spatulate, bristle-pointed, the margins and midribs rough with short, stiff hairs.

Weeds. 398 RVBIACEAE {MADDER FAMILY) Stems many-branched, ridged, and square, two to five feet long, very slender and too weak to support themselves, so that they clamber over other plants, clinging by means of backward-turning prickles on the stem angles. Leaves in whorls of sixes or eights, one to two inches long, narrowly spatulate, bristle-pointed, the margins and midribs rough with short, stiff hairs. Flowers very small, usually in groups of two to four in the upper axils. Corollas four-lobed, white, with four stamens inserted on the tube and two styles. Fruits small, twinned globular burs about an eighth of an inch broad, covered with short, hooked bristles. (Fig. 277.) Means of control Since the plant is an annual, if Galium thick- ets are cleaned out in the spring before the first burs form, the ground must soon be rid of their presence. ROUGH BEDSTRAW Galium asprellum, Michx. Native. Perennial. Propagates by seeds. Time of bloom: June to August. Seed-time: July to September, Range: Newfoundland to Ontario, Minnesota, and Nebraska, southward to Missouri and the Carolinas. Habitat: Alluvial ground; fence rows, thickets along Fig. 277.— Goose-grass or Cleavers (Galium Aparine). A vexation to the wool-grower in the autumn, when the vines have matured and become brittle; broken bits of the square, hooked stems work into and cling to the fleeces of the sheep, often transporting whole clusters of the seeds to new ground, from which the plants are difficult to dislodge because of their perermial roots. Stems two to six feet long, branching from the base, weak and reclining on bushes and other plants, clinging by means of down- ward-curving bristles on the stem angles. Leaves usually about an inch long, whorled in fives or sixes or occasionally in fours, oblong-. Plea
