*Hemp Nettle.* _Galeopsis Tetrahit._ Found in waste places, from July to September. The stalk grows to be 1 or 2 feet high; it is branching, and 4-angled, and swollen beneath the joints; coarse in fibre, and thickly covered by stout bristle-like hairs. In color dark green, or dull purplish-red at the joints. The long-pointed oval leaf is many ribbed, with a coarsely notched margin, thin but coarse texture, and roughened by hairs. Its color is dull green, lighter underneath. The leaves, on their hairy reddish stems, grow in pairs which spring at right angles to each other. The small tubular corolla spreads into 2 divisions, the upper being erect and arched, the lower 3-cleft with a slightly heart-shaped middle lobe; its color is pink or lavender. The 4 stamens stand erect under the upper lip. The hairy, green calyx is bell-shaped, with 5 bristling points. The flowers are set (supported by tiny hairy bracts) in whorls, in the angles of the upper leaves. A large variety, _G. grandiflora_, is often found in the same localities; the difference lies in the larger size of the corolla, which is clear white in color prettily marked with purple on its lower lip, and in the rounder shape of the calyx. Both plants are unpleasant to the touch because of their harsh bristle-like hairs.

The branching, leafy, and erect stalk grows from 6 to 12 inches high; it is strong and woody-fibred, not noticeably square as is usual among the Mints, minutely hairy, and soft to the touch. Its color is green, reddish near the root. The leaf is oval, with an entire margin, and is nearly smooth to the touch. It is green in color. The leaves, on short stems, grow in pairs. They are strong scented. The corolla is irregular in shape; 5-lobed, 4 of which are equal in size, slightly pointed, and erect or bent slightly forward, while the remaining lobe is long, narrow, and down-curving; in color a deep violet-blue. The 4 stamens and the pistil are long, pale, or reddish-violet; the green calyx is 5-parted. The flowers are set on short stems from the ends of the branches. The blossom opens in the early morning sunlight. At first the pistil and stamens extend beyond the flower in a long curve, but as the day advances their tips gradually draw inwards until they are brought into the throat of the corolla, and thus become the little blue curl which gives the plant its bye-name; by three o’clock of the afternoon the curl is completed and the flower falls. Its odor is strong, with a rank resemblance to the Pennyroyal. [Illustration: BLUE CURLS: Trichostema dichotomum.] POKEWEED FAMILY.
