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.
± 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). [Harley et al. 2004 Fam Generally Vasc Plant 7:167–275] 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. —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.
Key to Lamiaceae
Perennial herb [subshrub] glabrous to short-hairy. Stem: decumbent to erect, generally branched. Leaf: petioled to sessile; blade generally ovate, entire to toothed. Inflorescence: axillary, sessile or peduncled, collectively spike- or panicle-like; wide bract subtending flower, bracts generally overlapping. Flower: calyx radial, 5-lobed; corolla 2-lipped, upper lip ± entire, lower 3-lobed; stamens 4, enclosed by upper lip or exserted; style lobes ± unequal.Key to Origanum
45 species: Mediterranean, western Asia. (Greek: ancient common name, mountain delight) [Tucker & Rollins 1989 Baileya 23:14–27] Cult for tea, cooking herbs, essential oils (Origanum dictamnus L., dittany; Origanum majorana L., sweet marjoram).
Plant from rhizomes. Stem: 1–6 dm; short-hairy. Leaf: petiole 1–3 mm; blade 0.5–1.2 cm, entire, glabrous to puberulent, minutely gland-dotted; margin ciliate. Inflorescence: generally peduncled, collectively panicle-like; bracts 4–6 mm, pale green. Flower: calyx 2.5–3.5 mm, sparsely puberulent, gland-dotted; corolla 2-lipped for ± 1/3, 5–6 mm, white; stamens poorly developed or to 2.5 mm.
Disturbed areas; < 600 m. n Sierra Nevada Foothills, Sacramento Valley; native to Balearic Islands, Spain, Portugal. Hybrid between Origanum vulgare, Origanum majorana L.; plants sterile or fertile, cultivated, spreading from rhizomes or seeds. ± summer [Online Interchange]
