Trees or shrubs, deciduous, sometimes spiny. Leaves alternate, simple, estipulate, bases often oblique. Flowers bisexual, actinomorphic, often bracteate, in axillary cymes. Calyx lobes 4-10, toothlike or obsolete. Petals as many as calyx lobes, valvate, linear to lorate, sometimes basally coherent. Stamens as many as petals or 2-4 × as many, distinct, arising from an enlarged disk; anthers 2-celled, dehiscing longitudinally. Ovary inferior, commonly 1- or rarely 2-loculed; ovule solitary, pendulous; style and stigma simple, or 2- or 3-lobed. Fruit a drupe, crowned with persistent calyx and disk. Seeds 1 or 2, with straight embryo and copious endosperm.

Alangiaceae are treated here as separate from the Cornaceae, into which they have sometimes been placed. See the discussion under Cornaceae in Fl. China (14: 206. 2005).
