型態特徵

Trees, shrubs or sometimes herbs. Leaves simple, alternate, often distichous or arranged on the branchlet in one plane, chartaceous to coriaceous, entire; short-petioled; stipules thick, sometimes hooked at apex, mostly persistent. Flowers in axillary clusters or umbellate, cymules mostly bisexual, usually with distinctly pedicellate staminate flowers and subsessile or shorter pedicellate pistillate flowers, calyx-lobes mostly 5–6, without disc. Staminate flowers: sepals biseriate, often green or yellowish, spreading; stamens 2–8, united into a ellipsoid or oblong column, shorter than the sepals, the connectives exserted at tip, anthers longitudinally dehiscent; pistillode usually none or very minute between the anthers. Pistillate flowers: sepals sometimes erect, tubular and unequal; styles often connate into a short thick cylindrical column, lobed or toothed at summit, rarely free; ovary cells 3–15. Fruit a depressed-globose capsule of 3 or more 2-valved crustaceous cocci, each 2-seeded, suppressed or intruded at tip. Seeds hemispherical or laterally compressed.

Species about 300, chiefly in tropical Asia, the Pacific Islands, and Malaysia, few in America and Africa. Five species and two varieties in Taiwan.
