Mentha arvensis var. piperascens, Malinvaud. Japanese Mint. Perennial by running rootstocks, puberulent or finely pubescent throughout: sts. erect; with numerous branches, 2-3 ft. high: lvs. lanceolate and acute to broadly oblong and obtuse, narrowed at the base, l½-3½ in. long, sharply serrate, with low teeth: fls. in rather loose, axillary whorls, in distinctly pedicellate umbels, usually shorter than the slender petioles; calyx pubescent, its subulate teeth about half as long as the tube; corolla puberulent. This cult, variety is larger than M. arvensis itself, with larger lvs., and yields more oil. The species, M. arvensis, Linn., is naturalized widely from Eu.

Mentha canadensis, Linn. American Wild Mint. Perennial by runners and rootstocks: st. usually pubescent, with spreading hairs, erect or ascending, simple or branched, 6-30 in. high: lvs. ovate-oblong or lanceolate, glabrous or nearly so, 2-3 in. long, slender- petioled, the petioles often exceeding the nearly sessile whorls of light purple fls.: calyx pubescent. In wet soil or in water at the margins of streams. New Bruns. to Brit. Col. and southward to Va. and New Mex.—Often called peppermint, for which it is frequently mistaken and for which it is sometimes used as a substitute. It is variable in habit and also in the character of its oil.
