     65. MELIACEAE 楝科
    CHANG, CHING-EN

    Trees or shrubs. Leaves alternate, estipulate, mostly pinnate, usually not glandular punctate; leaflets opposite or alternate, usually quite entire and more or less oblique at base. Flowers usually unisexual (plant dioecious), rarely hermaphroditic, usually in axillary cymose panicles; calyx 3-6-lobed, or with free sepals, usually imbricate in bud; corolla contorted or imbricate, the petals 4-5 (rare 3 or 6 or more), distinct or connate, or adnate to the staminal tube and then valvate; stamens 5-10, hypogynous, mostly monadelphous by the connate filaments (distinct in Cedrela and Toona), the anthers erect, usually sessile on the tube, included or exserted, 2-celled, longitudinally dehiscing; hypogynous disc tubular, annular or obsolate, free or connate with the ovary, ovary usually free, 2-5 celled, the style single, the stigma disciform or capitate; ovules 1-2 in each cell or more, collateral or superposed. Fruit a berry, capsule, or rarely a drupe. Seeds often winged, endosperm fleshy or none.
    About 50 genera and 800 species, mostly tropical, widely spread over both hemispheres.
