Leaves mostly alternate, sometimes oppostie or whorled, sessile or petiolate; margins entire, serrate or rarely deeply lobed.
Flowers pollinated by birds or insects, caducous, 1–8 per axil, sessile or petiolate, developing in succession. Sepals 5, occasionally 4. Corolla 2-lipped, tubular or campanulate, often curved. Stamen 4 (5) included or exserted. Ovary 2-locular becoming 4-locular by development of 2 placental septa.
Fruits mostly dry or drupaceous and fleshy, cylindrical, top-shaped to globular; exocarp papery often separating from endocarp.
