Lop-seed.Phryma Leptostachya.
Found in light woods in July.
The large stout stalk bears slender branches, grows from 3 to 4 feet in height, and is square, hollow, and woody-fibred; it is smooth, or covered sparsely with small hairs, and grooved at the joints. Green, dashed with bronze, the branches sometimes purplish.
The lower leaves are large, broadly oval, and tapering to a sharp point, and sit on long trough-like stems; the upper are small and narrow. They have irregularly toothed margins, are thin in texture, and hairy; green in color. They are set on the stalk in pairs with a noticeable joint, the pairs occurring at right angles, and at a considerable distance apart.
The very small corolla is 2-lipped; the lower lip is 3-parted, the upper and smaller being 2-parted, and their color is light crimson with a violet tint; the long, dull green calyx is 2-divided, the upper division being longer, with 3 curving crimson tips. The flowers are arranged in pairs, at right angles to each other, in slender spikes, whose long stems bear one or two pairs of little leaves midway their length.
The blackish seed-pod is the oddest feature of this plant; it is grooved, and sharply turns down upon the stem, its little curved hooks bristling with expectation of getting a clutch upon awayfarer.
