General Information

Trees, shrubs, or sometimes subshrubs, evergreen, pubescent or glabrous. Leavs alternate, appearing opposite or pseudoverticillate, usually clustered at branchlet apex; leaf blade leathery or sometimes membranous, margin entire, undulate-dentate, or rugose. Inflorescences terminal or axillary, umbellate, corymbose, paniculate, or a solitary flower. Flowers bisexual, rarely polygamous. Sepals 5, free, usually short and small. Petals 5, free or partly connate. Stamens 5; filament glabrous; anther dorsifixed, ± sagittate, longitudinally dehiscent. Ovary superior, usually stipitate, of 2 or 3(–5)carpels, 1-loculed or incompletely 2–5-loculed, pubescent or glabrous; ovules usually numerous, sometimes 1–4; placentas parietal and equal in number to carpels, or basilar owing to reduction of ovules. 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.
