Leaves persistent or deciduous, alternate [spiral or distichous], simple; stipules absent; petiole present; blade coriaceous or chartaceous, margins toothed [entire], teeth deciduously gland-tipped. Inflorescences axillary, flowers solitary [2-3], bracteate. Flowers bisexual; perianth and androecium hypogynous; sepals [4-]5[-14], distinct or connate proximally, concave, relatively thick; petals 5(-8)[-14], distinct or connate proximally; nectary disc absent; stamens (50-)75-125(-150), in 1-5 bundles or not bundled, connate proximally or distinct, usually adnate to petals or corolla; anthers versatile [basifixed], 4-locular, dehiscent by longitudinal slits; pistils 1, [3-](4-)5(-6)[-10]-carpellate; ovary superior, [3-]5[-10]-locular; placentation primarily (falsely; H. Keng 1952) axile; ovules anatropous (campylotropous), bitegmic, tenuinucellate; styles 1 or 5[-6], simple [branched]; stigmas 1-5[-7], usually lobed. Fruits capsular, woody, dehiscence loculicidal and septicidal, [rarely irregular or fruits drupaceous]. Seeds 2-20, reddish brown to dark brown, compressed or lenticular [angular], sometimes winged, (testa vascularized, ± lignified); embryo straight, rarely curved; endosperm nuclear, usually slight.

    Shrubs or trees, evergreen or rarely deciduous, usually bisexual, rarely dioecious (Eurya) or androdioecious (Ternstroemia). Stipules absent. Leaves simple, alternate, petiolate or rarely sessile; leaf blade secondary veins pinnate, margin usually serrate or rarely entire. Flowers axillary or subterminal, solitary or sometimes to 3(-10 or more) in a cluster or raceme, pedicellate or subsessile. Bracteoles 2-8 or rarely more, persistent or caducous, sometimes undifferentiated from sepals. Sepals 5(or 6) or rarely more, persistent. Corolla white, red, or yellow; petals 5 or rarely more, basally connate or rarely distinct, adnate to androecium. Stamens numerous, in 1-6 whorls; outer filaments basally ± connate; anthers dorsifixed or basifixed, 2-loculed, laterally and longitudinally dehiscent. Gynoecium 3-5-carpellate. Carpels connate or rarely incompletely connate to nearly distinct. Ovary superior, rarely half inferior, 3-5-loculed, placentation axile or rarely nearly basal; ovules 2-5(to ca. 100) or more per locule; styles distinct to basally connate, rarely completely united. Fruit a loculicidal capsule or indehiscent and drupaceous or baccate, with 1 to many seeds per locule; pericarp woody, leathery, or fleshy; columella persistent or ± degenerating. Seeds globose, semiglobose, compressed oblong, ovoid, or reniform, winged or wingless; testa bony, leathery, or sometimes with a fleshy red outer layer or sarcotesta (in Anneslea and Ternstroemia), smooth or honeycombed; hilum umbilicate or linear; endosperm present or absent; embryo large or small; cotyledons fleshy or thin.
