Mentha suaveolens
PINEAPPLE MINT


Higher Taxonomy
Family: Lamiaceae (Labiatae)View DescriptionDichotomous Key
Common Name: MINT FAMILY
Habit: Annual to shrub [tree, vine], glabrous to hairy, generally aromatic. Stem: generally erect, generally 4-angled. Leaf: generally simple to deeply lobed, generally opposite, generally gland-dotted. Inflorescence: generally cymes, generally many in dense axillary clusters surrounding stem, generally separated by evident internodes or collectively crowded, spike- or panicle-like, occasionally head-like or raceme, subtended by leaves or bracts; flowers sessile or pedicelled. Flower: generally bisexual; calyx generally 5-lobed, radial to bilateral; corolla generally bilateral, 1--2-lipped, upper lip entire or 2-lobed, +- flat to hood-like, occasionally 0, lower lip generally 3-lobed; stamens generally 4, epipetalous, generally exserted, paired, pairs generally unequal, occasionally 2, staminodes 2 or 0; ovary superior, generally 4-lobed to base chambers 2, ovules 2 per chamber, style 1, generally arising from center at junction of lobes, stigmas generally 2. Fruit: generally 4 nutlets, generally ovoid to oblong, smooth.
Genera In Family: +- 230 genera, 7200 species: worldwide. Many cultivated for herbs, oils (Lavandula, lavender; Mentha, mint; Rosmarinus, rosemary; Thymus, thyme), some cultivated as ornamental (in California Cedronella, Leonotis, Monarda, Phlomis). Note: Moluccella laevis L., shell flower, historical waif in California. Satureja calamintha (L.) Scheele subsp. ascendens (Jordan) Briq. reported as alien but not naturalized. Salazaria moved to Scutellaria; California Hyptis moved to Condea, California Satureja moved to Clinopodium.

Genus: MenthaView DescriptionDichotomous Key


Common Name: MINT
Habit: Perennial herb from rhizomes, glabrous to hairy. Stem: generally ascending to erect, generally branched. Leaf: petioled to sessile; blade elliptic to ovate or lanceolate, toothed to lobed. Inflorescence: head-like in leaf axils or collectively spike- or panicle-like and subtended by bracts. Flower: calyx +- radial, generally 10-veined, lobes 4--5, equal or not; corolla +- 2-lipped, lips generally equal, upper lip notched, lower lip 3-lobed; stamens 4, +- equal, generally exserted, filaments glabrous, anthers segments parallel, distinct. Fruit: nutlets +- ellipsoid, tip rounded.
Species In Genus: 18 species: temperate. North America, Eurasia. Etymology: (Latin: ancient name for mint) Note: Cult for oils, flavoring, herbs. Hybrids in California generally sterile, spreading from rhizomes.
Unabridged Note: Many cultivated and naturalized populations derived from hybridization, generally polyploid, some sterile, reproducing vegetatively.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
