    Habit
    Dioecious shrubs or small trees.
    Indumentum
    Indumentum simple (± confined to the inflorescences).
    Leaves
    Leaves alternate, petiolate, stipulate, stipellate or not, simple, entire, subentire or remotely and shallowly serrulate-denticulate, penninerved, with 2–4 glands at the top of the petiole or on the upper surface of the lamina at the base.
    Stipules
    Stipules fused into an elongate sheath, which on falling leaves a distinct annular scar.
    Inflorescences
    Inflorescences axillary or borne on old wood, racemose, solitary or fasciculate, shortly pedunculate or not, strobiliform at first, later laxly flowered; bracts broad, concave, ciliate, persistent; male inflorescences 1–more-flowered; female inflorescences usually 1-flowered; bracteoles 2.Male flowers pedicellate, pedicels jointed near the base; calyx closed in bud, later splitting into 2–5 membranous valvate lobes; petals 5–8, free, imbricate; receptacle convex, covered in contiguous disk glands, pubescent; stamens 20–55, free, erect in bud, arising from pits in the glandular surface, anthers fixed at apex, extrorse, the thecae almost free, pendulous from a thickened glandular apiculate connective, longitudinally dehiscent; pistillode reduced or absent.
    Flowers
    Female flowers: pedicels stouter than in the male, jointed near the base; calyx and petals resembling those of the male; disk hypogynous, annular, thickened, alveolate; staminodes often present, filiform, arising from the alveoli; ovary 3-locular, with 1 ovule per locule; styles 3, almost free, bipartite, the stigmas papillose.
    Fruits
    Fruit 3-locular, dehiscing into 3 bivalved cocci; endocarp thinly woody; columella persistent, apically tricornute.
    Seeds
    Seeds subglobose, ecarunculate; testa crustaceous, shiny; albumen thick, fleshy; embryo straight or slightly curved; cotyledons broad, flat.
