Wild Mint.Mentha Canadensis.
Found on moist banks, beside running water, commonly in the shade, from July to September.
The branching, leafy stalk is square, coarse-fibred, hairy, and about 1 or 2 feet in height. In color it is pale green, sometimes bronzy.
The long leaves are pointed at both ends (except the upper leaves, which are wider at the base), with notched margins, midribs prominent underneath, and a coarse texture, the upper surface being rough, while the underside is hairy; green. They are set on short stems, and grow in pairs, at opposite angles to each other.
The corolla of the very small flower is shaped like a 4-divided tube, the upper division being notched at its tip: it is white, or faintly tinged with pink or lavender; the hairy calyx is pale green, or pinky. The flowers are arranged in close rings about the stalk, in the angles of the upper leaves.
The scent of this plant resembles Pennyroyal, though less strong.
