    Habit
    Perennial woody herbs, subshrubs or suffrutices with annual stems arising from a woody rootstock, aromatic or not
    Stem
    Stems erect, woody at base
    Leaves
    Leaves opposite or in whorls of 3 or 4, petiolate or sessile
    Flowers
    Flowers hermaphrodite, arranged in 2–4flowered verticils, each flower being subtended by an inconspicuous bract
    Calyx
    Calyx persistent, bilabiate, shortly tubular; posterior lip large, ovate, entire, shortly decurrent on tube; anterior lip 4-lobed, lateral lobes deltate, cuspidate, median lobes lanceolate, long-acuminate; fruiting calyx with throat open, glabrous; posterior lip accrescent, lateral lobes of anterior lip often with posterior margin extended towards the posterior lip and with a small lanceolate or subulate tooth, median lobes acicular or subulate, curving upwards, usually longer than the lateral lobes
    Corolla
    Corolla bilabiate; tube parallel-sided exserted from the calyx, straight; posterior lip 4-lobed, median lobes narrower than and exceeding the lateral, anterior lip entire, cucullate, enclosing stamens or slightly deflexed
