The opposite, petioled leaves, broadly oval at the base, taper-pointed, coarsely toothed, three-nerved, and veiny, are thin and easily skeletonized by the insects that enjoy the leaves of all this clan of plants. From one to four feet high, the White Snakeroot grows in the United States and Canada as far west as Nebraska. Closely allied to the eupatoriums, and with similar inflorescence, is the CLIMBING BONESET or HEMPWEED (Willughbaeaa scandens; Mikania scandens of Gray.) Straggling over bushes in swamps, by the brookside thicket, or in moist, shady roadsides, the vine reveals its kinship to the boneset instantly it comes into bloom in midsummer, although its flower clusters are occasionally pinkish. The opposite, petioled leaves are quite different from the boneset's, however, being heart-shaped at the base, and taper-pointed, somewhat triangular, two to four inches long, and one or two inches wide. From Massachusetts and the Middle States even to South America and the West Indies is its range. WHITE ASTERS or STARWORTS (Aster = a star) Thistle family In dry, open woodlands, thickets, and roadsides, from August to October, we find the dainty WHITE WOOD ASTER (A. divaricatus; A. corymbosus of Gray) its brittle zig-zag stem two feet high or less, branching at the top, and repeatedly forked where loose clusters of flower-heads spread in a broad, rather flat corymb. Only a few white rays - usually from six to nine - surround the yellow disk, whose forets soon turn brown. Range from Canada southward to Tennessee. First to bloom among the white species, beginning in July, is the UPLAND WHITE ASTER (A. ptarmicoides), which elects to grow in the rocky or dry soil of high ground in the northern United States westward to Colorado. The leaves, which resemble grayish-green shining grass-blades, arranged alternately up the rigid stem, and diminishing in size near the top until they become mere bracts among the flowers, enable us to name the plant. The heads, in a branching cluster, are not numerous; each measures barely an inch across its ten to twenty snow-white rays; the center is of a pale yellow-green, turning a light brown in maturity.
