Indian Tobacco.Lobelia inflata.
Found in damp places, and along roadside ditches, in August.
The leafy, sometimes branching stalk grows from 12 to 18 inches, and is not large, though less slender than the Spiked Lobelia, its texture being also coarser; it is very slightly rough to the touch, and light green in color.
The leaves near the foot are about an inch long, and a blunt oval shape; near the top they become smaller and narrower; with coarsely toothed margins, a thin texture, and dull green color. They clasp the stalk alternately.
The flowers are smaller than the other Lobelias mentioned; the corolla is lilac, with a white spot on the lower lip; the calyx, whose 5 divisions are thread-like, is purplish-green. The flowers, on their little foot-stems, are placed in a scattering fashion upon the stalk to form a long terminal spike; each flower is supported by a little leaf or bract.
As the blossoms fall the seed-pods swell into a round and inflated shape, which, together with the scantiness of its bloom, gives the spike an untidy look, unusual in this class of delicate forms and elegant proportions.
