*Upland White Aster.* _Aster ptarmicoides._ Found among rocks, in dry soil, in August. The stalk, erect in bearing, from 1 to 2 feet in height, is single, and very slender; smooth at the foot, though rough above. Of a gray-green color. The leaf is like a grass blade, long, and narrow, with an entire margin, and noticeable midrib; the upper surface is rough, the edge being harsh to the touch, the under surface is shining. Color, gray-green. Arranged alternately, and clasping the stalk with an upward curve. The disc flowers are small; of a pale yellow-green. The ray flowers, 15 or 20 in number, are short, pointed; pure white. The heads are arranged in a flat-topped loose cluster. When the disc flowers mature they turn to a light brown color; at one period of development the pale pistils are prominent. There is an individual excellence about this Aster, existing especially in the curve of its leaf. [Illustration: UPLAND WHITE ASTER: Aster ptarmicoides.] *White Wood Aster.* _Aster corymbosus._ Found in moist woods during July and August. The stalk, 12 or 15 inches high, branches near the top, and is sometimes zigzag in growth; slender, and smooth. In color a strong rich purple, or green, streaked with red or purple. The lower leaves are heart-shaped, the upper long-oval, with tapering points; the margin notched, and the texture thin. Color green, lighter underneath. Set on short stems, and arranged alternately. The disc flowers are few, and yellow; the 4 to 8 ray flowers are about a half inch long, narrow, delicate in texture, arranged in a scattering row, and pure white in color. The cups are small; the heads grouped in loose, leafy terminal clusters. Perhaps the most daintily finished of the white Asters, it is also the most shy, loving shady nooks and lonely places amongst trees. [Illustration: WHITE WOOD ASTER: A. corymbosus.] *New England Aster.* _Aster Novæ-Angliæ._ Found in September in moist fields and waysides. The strong stalk varies much in height (from 3 to 7 or 8 feet); it branches somewhat at the summit and bears many leaves, and is hairy to the touch. In color green, or purplish. The leaf is lance-shaped, with a pointed tip, and a heart-shaped base, an entire margin, and hairy surface. The color is a fine, cool green. The leaves clasp the stalk closely, and are arranged alternately, and near together. The disc flowers are yellow, inclining to purplish, gathered in a large, noticeable tuft; the ray flowers are large and long (15 to 20 in number), of fine texture, and of a rich deep violet or almost royal purple color. The cup is large, sticky, and its many tips turn abruptly outward; green in color. The heads are set on short, sometimes leafy, stems in small terminal groups. A singularly handsome Aster, with a fine, free gesture, and admirable color harmony. [Illustration: NEW ENGLAND ASTER: A. Novæ-Angliæ.]
