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.

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.
