Herbs, perennial, or shrubs, rarely small trees, evergreen or deciduous, sometimes rhizomatous or tuberous. Stems with or without spines. Leaves alternate, opposite, or basal, simple, or 1-3 × pinnately or 2-3 × ternately compound; stipules present or absent; venation pinnate or palmate. Inflorescences terminal or axillary, racemes, spikes, umbels, cymes, or panicles, or flowers fascicled or solitary. Flowers pedicellate or sessile, bisexual, radially symmetric; bracteoles or bracts present or absent. Perianth usually 2- or 3-merous, rarely absent. Sepals 6-9, often petaloid, distinct, in 2 or 3 whorls. Petals 6, distinct, flat, hooded, pouched, or spurred; nectary present or absent. Stamens 6, opposite petals; anthers 2-celled, dehiscing by valves or longitudinal silts. Ovary superior, apparently 1-carpellate; ovules numerous, rarely solitary; placentation marginal or appearing basal; style present or absent, sometimes persistent in fruit as a beak. Fruit a berry, capsule, follicle, or utricle. Seeds 1 to numerous, sometimes arillate; endosperm abundant.

Seventeen genera and ca. 650 species: mainly in the north temperate zone and on subtropical mountains; 11 genera and 303 species (272 endemic, one introduced) in China; 17 additional species (15 endemic) are insufficiently known.

Editors’ note. The Berberidaceae were to be published in Flora of China Volume 7 (2008). However, a problem with the treatment of Berberis necessitated postponing publication of the family until the present volume. See the comments under Berberis, below.
