    Habit
    Perennial herbs to shrubs, rarely gynodioecious, or dioecious ( sect. parviflorae epling - see hart 1985); often aromatic
    Leaves
    Leaves entire to toothed, often rugose
    Inflorescences
    Inflorescence terminal and often axillary, a paniculate thyrse of lax, (1-) 3- to many-flowered cymes, or spiciform of ± congested, usually sessile, 6- to many-flowered verticillasters
    Bracts
    Bracts usually small
    Bracteoles
    Bracteoles inconspicuous
    Flowers
    Flowers large to very small
    Calyx
    Calyx ± actinomorphic to weakly 2-lipped, 5-lobed (3/2), lobes deltoid to subulate or aristate, tube campanulate, 10-15-nerved, often accrescent and inflated, lobes spreading to connivent, throat exannulate
    Corolla
    Corolla weakly 2-lipped, 5-lobed (2/3), white, yellowish, purplish to red or blue, lobes often subequal, or anterior lobe larger, tube cylindrical to campanulate, sometimes shorter than calyx, usually annulate within
    Stamens
    Stamens 4, didynamous, included to long-exserted, anterior pair usually longer, ascending, thecae 2, divergent to divaricate, elongate to oblong, sometimes confluent
    Stigma
    Stigma-lobes short, subequal
    Disc
    Disc 4-lobed, nutlets ovoid, smooth, brown or black, abscission scar minute, not mucilaginous.
    Note
    2n = 32, 66.  About 40 species. Epling (1948) recognized eight sections, based mainly on inflorescence structure and floral morphology.  Hart (1983) recognized two: sect. Lepechinia and sect. Parviflorae, considering the former to be polyphyletic.
    Ecology
    Often montane
    Distribution
    Andes from Argentina and Chile northwards to Mexico and U.S.A. (California), with outlying species in Brazil and Hawaii, the Chilean L. chamaedryoides (Balbis) Epling naturalized in Réunion.
