Weeds. 432 COMPOSITAE {COMPOSITE FAMILY). Fig. 300. — Smooth Aster (Aster laeris).

Heads numerous, in slender open panicles, each about an inch broad, the rays deep violet-blue, sometimes purple; involucre .bell-shaped, its bracts imbricated in several rows, smooth, acute, rigid, green-tipped. Achenes smooth, with a tawny pappus. (Fig. 300.) Means of control Enrich ,the ground and enable it to sup- port plants of more worth. A cultivated crop, heavily fertilized and well tilled, fol- lowed by a clean seeding of clover or grass, will drive out this and many other weeds. WHITE HEATH ASTER Aster ericoldes, L.
