型態特徵

Herbs, shrubs, small trees, or climbers. Stems and leaves with included phloem, sometimes prickly or thorny; hairs simple, branched, or stellate, sometimes glandular. Leaves alternate, solitary or paired, simple or pinnately compound, entire, dentate, lobed, or divided; stipules wanting. Inflorescences terminal and overtopped by continuing axes, but usually appearing axillary, extra-axillary, or leaf opposed, often apparently umbellate, racemose, paniculate, clustered, or flowers solitary. Flowers mostly bisexual, mostly 5-merous; calyx mostly partly lobed; petals united; stamens inserted within corolla, alternating with the lobes, alike or 1 or more reduced, anthers dehiscing longitudinally or by apical pores; ovary 2–5-locular; placentation mostly axile, ovules numerous; style single, terminal. Fruit a berry or capsule; seeds with copious endosperm; embryo mostly curved; fruiting calyx mostly persistent, often becoming enlarged.

About 95 genera with 2,300 species; best represented in western tropical America, widespread in temperate and tropical regions; in Taiwan 10 genera (seven introduced) and 30 species. Some species are cultivated as ornamentals, medicinals or crop plants.
