    LIU, TANG-SHUI and LO, HANN-CHIANG

    Mucilaginous trees or shrubs, infrequently herbs, generally covered with stellate, sometimes simple hairs, or lepidote scales. Leaves alternate, rarely opposite, entire or more or less dentate or lobed, stipulate, petiolate; stipules paired, fugacious or absent. Inflorescence axillary or terminal, often opposite a leaf, sometimes borne on the stem, cymose, umbellate, paniculate or flowers generally bracteolate, small or large, hermaphroditic, sometimes imperfect, generally actinomorphic, sometimes calyculate; calyx usually valvate, seldom imbricate, gamo- or poly-sepalous; sepals (2-3-)4-5(-6-8), caduous, persistent or accrescent; petals 4-5(-6), sometimes sepaloid, rarely absent, contorted, imbricate or valvate, usually free, often glandular at base; stamens inserted on receptacle or gonophore, usually numerous, rarely less than 10, sometimes partially staminodial in hermaphroditic flowers, absent or staminodial in pistillate ones, free or shortly connate at base into a tube or into 5 or 10 phalanges; anthers usually 2-thecate, longitudinally dehiscent or apically porose; gynoecium with (1-)2-5(-10) syncarpous carpels, infrequently with 5-6 apocarpous carpels; ovary usually superior, rarely subinferior to inferior, sessile on receptacle or gonophore, sometimes borne on a gynophore, (1-)2 to many-celled; cells sometimes divided by false partitions, with (1-)2-many ovules in every cell and generally with axile placentation, infrequently parietal; style usually simple; stigma entire or more or less 2- to 10-lobed; ovules anatropous. Fruit baccate, drupaceous or capsular, smooth or spinose, sometimes winged, 2- to 10-locular, rarely 1-locular by abortion, variously dehiscent or indehiscent; seeds solitary to many in every loculus, sometimes pilose or arillate; with abundant or scanty albumen; embryo straight or slightly curved; cotyledons foliaceous, seldom carnose.
    About 36 genera with nearly 400 species, mostly in the tropics, few in temperate regions; five genera with 14 species in Taiwan.
