    Habit
    Perennial, aromatic herbs, subshrubs or shrubs
    Leaves
    Leaves opposite, ± leathery, usually small, margin thickened, entire or almost so
    Inflorescences
    Inflorescence thyrsoid or with the cymes reduced to single flowers; bracts ± similar to the ordinary leaves but mostly gradually smaller upwards in the inflorescence; cymes 1–many-flowered; bracteoles present, small
    Calyx
    Calyx 5-lobed, scarcely accrescent, slightly zygomorphic to 2-lipped; tube (11–)13(–15)-veined, ± hairy inside near the mouth; posterior lip 3-lobed; anterior lip 2-lobed, divided to the base, with the lobes mostly longer and narrower
    Corolla
    Corolla 2-lipped; posterior lip emarginate; anterior lip almost flat, 3-lobed
    Stamens
    Stamens 4, ascending under the posterior corolla lip; thecae divaricate, separated by a short connective
    Ovary
    Ovary deeply 4-lobed, style gynobasic, branches usually equal or subequal
    Fruits
    Nutlets matt, glabrous, with a ± distinct areole at the scar, producing mucilage when wet.
    Note
