Overview
Trees or shrubs, evergreen, glabrous or pubescent, occasionally spiny. Leaves alternate, occasionally opposite, estipulate; leaf blade mostly leathery, margin entire, rarely dentate or lobed. Inflorescences umbellate, corymbose, paniculate, or a solitary flower, bracteate and bracteolate. Flowers usually bisexual, sometimes polygamous, actinomorphic, rarely zygomorphic, usually 5-merous (except ovary) . Sepals usually free or slightly connate. Petals free or connate, white, yellow, blue, or red. Stamens opposite sepals; filament filiform; anther basifixed or dorsifixed, 2-loculed, dehiscing longitudinally or by pores. Ovary superior, of 2 or 3( 5) carpels, usually 1-loculed or incompletely 2 5-loculed; ovules numerous, anatropous; placentation parietal, axile, or basilar. Style short, simple or 2 5-lobed, persistent or deciduous. Fruit a capsule dehiscing by adaxial suture, or a berry. Seeds numerous; testa thin; endosperm well developed; embryo small.
Nine genera and ca. 250 species: tropical and subtropical regions of Africa, Asia, Australia, and Pacific Islands, especially Australia; one genus and 46 species (33 endemic) in China.[1]

Style short, simple or 2-5-lobed, usually persistent. Capsule ellipsoid or globose, sometimes compressed, dehiscing by 2-5 valves; pericarp woody or leathery, usually with horizontal striae adaxially. Seeds usually surrounded by glutinous or greasy material.[2] [more]
