    Loganiaceae, A. J. M. Leeuwenberg. Flora Zambesiaca 7:1. 1983

    Habit
    Shrubs, undershrubs, or sometimes lianas, with simple hairs or nearly glabrous.
    Stem
    Stems much branched; twigs usually thin.
    Leaves
    Leaves opposite, those of a pair equal or subequal, shortly petiolate; lamina mostly papyraceous when dry, ovate to very narrowly elliptic, variable in shape and size, on lateral branches often smaller, entire or obscurely sinuate–dentate, pinnately veined; veins conspicuous.
    Stipules
    Stipules membranaceous, usually triangular, entire, those of a pair united, or all fused into a short ocrea.
    Inflorescences
    Inflorescence axillary or terminal, usually on short lateral branches, mostly obliquely and incompletely dichasial, i–many–flowered.
    Bracts
    Bracts mostly small and sepal–like.
    Flowers
    Flowers 5–merous, dimorphic.
    Calyx
    Sepals green, connate at the base up to half their length, equal or unequal, ovate to very narrowly elliptic, obtuse to subulate at the apex, entire or sometimes obscurely sinuate–dentate.
    Corolla
    Corolla white, sometimes pale yellow, orange, or red, yellow at the base or not, infundibuliform, 2·5–9 x as long as the calyx; tube about 3–5 x as long as the lobes; lobes imbricate in the bud, spreading, orbicular or nearly so, rounded, entire or sometimes obscurely sinuate–dentate.
    Stamens
    Stamens included or in long–staminate flowers often exserted, equal or unequal; filaments pubescent or sometimes glabrous (M. microphylla, M. brunonis), inserted at one–quarter to one–third from the base of the corolla tube; anthers orbicular or oblong; cells 2, discrete, divergent at the base, dehiscent throughout by a longitudinal slit.
    Pistil
    Ovary superior, ovoid, usually with 2 impressed lines, 2–celled, with 2 ovules in each cell; style simple, shorter or longer than the stamens, when longer slightly exserted, deciduous, minutely pubescent with glandular hairs; stigma twice dichotomously branched, lobes narrow, pubescent (hairs glandular).
    Ovules
    Ovules attached to the base of the septum.
    Fruits
    Fruit capsular, obcordate, bilobed, or occasionally ellipsoid, flattened, with an impressed line in the middle, loculicidal, 4–valved; valves hinging on the septum; cells with 1–2 seeds.
    Seeds
    Seeds plano–convex (not so if fruit ellipsoid), obliquely ovate to orbicular, pale brown, dull and densely appressed–pilose (African species).

    Habit
    Small much-branched shrubs
    Leaves
    Leaves opposite, ± elliptic, entire
    Inflorescences
    Inflorescences of few-flowered usually axillary cymes
    Flowers
    Flowers heterostylous
    Calyx
    Calyx regularly 5-lobed; lobes longer than the tube
    Corolla
    Corolla funnel-shaped, white, with or without yellow patches; lobes 5, shorter than the tube
    Stamens
    Stamens 5, alternate with the corolla lobes, inserted low in the corolla-tube
    Pistil
    Ovary superior, 2-locular with 2 large erect basal ovules in each loculus; styles 4 or fewer and then variously divided to support 4 stigmas
    Fruits
    Capsule flattened at right-angles to the septum, forming an almost plane fruit broader than long with an emarginate apex, dehiscing loculicidally; seeds 1–2 in each loculus.
