Synonyms: Baueraceae APNI*
Davidiaceae APNI*
Eucryphiaceae APNI*
Davidsoniaceae APNI*

Description: Trees or shrubs, rarely climbers.

Leaves opposite, rarely whorled or alternate, margins toothed [occasionally entire], simple or compound, often 3-foliolate, sometimes 1-foliolate, pinnate or palmate; stipules usually interpetiolar, occasionally absent, often conspicuous, falling early and leaving distinctive scars between petiole bases.

Inflorescence usually cymose, sometimes flowers in racemes, panicles or clustered in heads, rarely solitary. Flowers actinomorphic, generally bisexual; floral parts hypogynous, perigynous or epigynous. Sepals 4–10, sometimes basally fused and enlarging during fruit formation. Petals absent or 4–10, usually small. Stamens 4–20. Ovary usually superior or rarely half-inferior, 1–5-locular.

Fruit a capsule, a nut or drupaceous.

Distribution and occurrence: World: 29 genera, c. 265 species, Southern Hemisphere, tropical & temperate regions. Australia: 17 genera, about 35 species, Qld, N.S.W., Vic., Tas., S.A. & 1 species SW W.A.

Now considered to include genera previously assigned to separate families Baueraceae, Davidsoniaceae, Eucryphiaceae, e.g. in Flora of NSW (1990). Coachwood, Ceratopetalum apetalum, produces timber that is used extensively in carpentry, cabinet making and flooring. Ceratopetalum gummiferum (Christmas Bush) is cultivated as an ornamental for its reddish calyces in the fruiting stage. Early settlers used Callicoma (Black Wattle) as the framework for their huts onto which clay was plastered; this method of construction was referred to as `wattle and daub'.
