Evergreen or deciduous shrubs or small trees, rarely perennial herbs. Leaves alternate or rarely opposite or basal, entire to pinnate or ternate; stipules small or absent. Inflorescence a panicle or raceme, or flowers solitary. Flowers bisexual. Perianth in 2–6 whorls, each of 3 segments; outer whorl smaller, sepaloid, inner with nectaries and sometimes regarded as petaloid staminodes. Stamens (4–)6(–18), usually opening by 2 valves hinged at the apex. Ovary unilocular, ovules 1-numerous; stigma sessile or on a short style. Fruit a berry or occasionally dry and dehiscent or indehiscent.

A family of about 16 genera and 550 species found in Eurasia, Africa and the Americas. Several species of Berberis L., Mahonia Nutt. and Epimedium L. are cultivated as ornamentals. 3 genera and 5 species are naturalized in Australia. The Berberidaceae are placed in the Ranunculales and are related to the Ranunculaceae (cosmopolitan) and Menispermaceae (mostly pantropical) (see Stevens 2007 & references cited therein).

Mahonia +

+ Mahonia aquifolium (Pursh) Nutt. (native to North America) is naturalized in South Australia and New South Wales (including the A.C.T.), and sparingly naturalized in Victoria (see also Morley 2007). It has been collected along a road in the Tasmanian Central Highlands.


Berberis L., Sp. Pl. 1: 330 (1753).

Shrubs, evergreen or deciduous with yellow wood, usually with 3–5 partite axillary spines which are the modified basal leaves of long shoots. Leaves alternate, entire, margins often spiny. Inflorescence axillary, racemose, fasciculate or paniculate. Perianth segments in 4–5 whorls, the outer sepaloid, the inner petaloid with basal nectaries. Stamens 6. Fruit a few-seeded berry.

A genus of about 500 species in Europe, northern Africa, southern Asia and America. In Australia 2 or 3 species are occasionally naturalised.
