Trees or shrubs, deciduous or evergreen, usually hairy or rarely glabrous. Leaves simple, alternate, clustered or subverticillate, entire or rarely lobed, penninerved; stipules present, at first enclosing and protecting the buds, early caducous and leaving an annular scar around the node, sometimes absent. Flowers terminal, axillary or rarely in a cyme of 2-3-flowered, usually bisexual, rarely hermophrodite or dioecious; perianth usually petaloid, lobes 6-9-(45) in 2-many whorls, 3 (6) on each whorl; stamens many; ovary superior, carpels numberous, distinct or rarely connate, insect-pollinated; ovules inserted on sutures; embryo small; endosperms abundant.
