PRIMROSE FAMILY. PRIMULACEÆ. *Star-flower.* _Trientalis Americana._ *Star Anemone.* *Star-of-Bethlehem.* *Chickweed Wintergreen.* Found in moist shade during May. This very slender and smooth little stalk grows from 3 to 5 inches in height, bears one or two sheath-like leaves near the root, and terminates in a whorl of leaves at the top. It is green, slightly reddish at the foot. The long leaf is sharp-pointed at both ends, with an entire margin, a thin and delicate texture which shows plainly the pattern-like tracery of the ribs and veins, and a shining surface; the color is a full green. 6, or more, leaves, of unequal size, spread in a whorl upon the summit of the stalk. The flower has 7 nearly diamond-shaped parts, of a thin texture, and pure white color; they spread flat, their edges just overlapping in a 7-pointed star, the 7 long, and narrow, greenish divisions of the calyx alternating with them; the 10 thread-like stamens are white, with orange tips. A single flower, borne on a slender stem, rises from the whorl of leaves. The number of the corolla-divisions sometimes varies, but 7 is the usual measure. It is noticeable that the flower-stem is set a trifle underneath the lap of the leaves, causing an inclination of the star to one side. A tiny leaf is found sitting on the stalk just under the leafy canopy. [Illustration: STAR FLOWER: Trientalis Americana.] *Loosestrife.* _Lysimachia quadrifolia._ Found in moist grounds, and woods, in June and July. The single stalk, from 12 to 18 inches in height, is hairy and faintly ridgy, and light green in color. The leaf is oval and pointed at both ends; from 2 to 3 inches long, with a strong midrib; the upper surface smooth to the touch, the lower hairy, and the color yellow-green. The leaves are set close on the stalk in whorls of fours and fives, with a single pair occurring near the foot of the stalk. The divisions of the flower are 5, long-pointed, fine in texture, and light yellow, with a few tiny red streaks, and a bright red marking at their base; the 5 erect, pale yellow stamens, tipped with tawny, are united at the foot in a collar; the calyx-parts are 5, narrow, pointed, and light green. The flowers, set on thread-like stems spring from the angles of the leaves,--a flower for each leaf. As many as six or seven whorls of leaves, four often accompanied by flowers, are found on a single stalk.

The stalk, from 12 to 18 inches in height, is branching near the top, leafy, and smooth, but grooved beneath the branches; it is hollow, and has a stiff fibre; pale yellow-green.
