VII. 2. B. Subtribe Menthinae (Dumort.) Endl. (1838).
Perennial, rarely annual herbs, subshrubs or shrubs, usually gynodioecious, strongly aromatic; stems often rhizomatous; inflorescence of few- to many-flowered axillary cymes, pedunculate or not, often forming either dense verticillasters along stem, in axils of leaf-like bracts, or congested into terminal spiciform thyrses in axils of reduced bracts; bracts leaf-like or reduced; bracteoles inconspicuous, rarely broader or digitately lobed; calyx ± actinomorphic, 5-(rarely 4-)lobed, lobes subequal, triangular to subulate or acicular, or slightly 2-lipped, (3/2), anterior lobes often longer, tube cylindrical to infundibuliform, 10-15-nerved, throat hairy or glabrous; corolla ± actinomorphic, 4-lobed, lilac, pink or white, lobes spreading, subequal, or posterior lobe slightly broader, often emarginate, corolla-tube ± cylindrical or rarely gibbous on anterior side, usually included within calyx-tube; stamens 4, subequal, exserted, divergent (included in male-sterile plants), anthers ellipsoidal, thecae parallel, distinct; stigma-lobes subequal, shortly spreading; disc ± symmetrical; nutlets ovoid, smooth to rugose, pale to dark brown, not mucilaginous; 2n = 18, 20, 24, 36, 40, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 108, 120, 132. About 20 species in damp, open habitats, often by water, especially Mediterranean and Australasian (one species in New Zealand), but extending through Europe, Asia and Africa to the Cape, and with one species in North America. Some species cultivated since antiquity as potherbs and now introduced worldwide. Hybrids are of frequent occurrence in sect. Mentha (Harley and Brighton 1977). These can persist and spread widely by vegetative means. Mentha spicata L. and its hybrids, including M. x piperita L., and, in the subtropics, M. canadensis L. are of commercial importance. No modern infra-generic classification has yet been published, while previous systems such as those by Briquet (1897) are unsatisfactory.
