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.
