Description Trees, shrubs or woody climbers, very rarely subherbaceous. Leaves opposite, verticillate or more rarely alternate, usually petiolate, almost always entire, often conspicuously lepidote. Petioles sometimes persisting after leaf-fall, forming thorns. Flowers usually perfect, actinomorphic or rarely slightly zygomorphic, in elongated or subcapitate, axillary or extra-axillary spikes or racemes or in terminal or terminal and axillary, often leafy panicles. Receptacle usually clearly divided into a lower part (lower receptacle) surrounding and adnate to the ovary and an upper part (upper receptacle) varying from patelliform to elongate-infundibuli- form terminating in the calyx-lobes. Upper receptacle often further differentiated into a lower part containing the disk and a usually more expanded upper part. Calyx-lobes usually 4 or 5 (rarely more) deltoid to filiform or sometimes scarcely developed. Petals usually 4 or 5 (very rarely absent but never in Panama species except perhaps by abortion) small and inconspicuous or showy and exceeding the calyx-lobes, white, yellow, orange, red or purple, glabrous or hairy, occasionally scaly. Stamens usually twice as many as the petals, inserted inside the upper receptacle, often biseriate, usually exserted; anthers dorsifixed, versatile. Disk intrastaminal, glabrous or hairy, sometimes very small or absent. Ovary com- pletely inferior, probably of 1 carpel, unilocular with usually 2 (occasionally up to 6) pendulous ovules of which only 1 develops. Style simple, free, usually ex- serted, rarely very short. Fruit (pseudocarp) 4- to 5-winged, -ridged or -angled, sessile or stipitate, usually indehiscent, 1-seeded; pericarp usually thin and papery, sometimes leathery, more rarely fleshy.

Distribution About 250 species throughout the tropics (except Australia); extending in the New World from Mexico to Argentina.
