Shrub or small tree with stout terete branches, bark becoming corky. Leaves coriaceous, up to 45 by 17 cm, oblong, elliptic or lanceolate-oblong; base cordate, truncate or cuneate, apex narrowed to an acute apex; lower surface with dense or sparse pubescence or glabrous; margin with few to many sharp teeth; midrib prominent; secondary and tertiary veins forming a distinct reticulation; petiole stout, 5-15 mm. Inflorescence of axillary fascicles which continue to appear from successive buds at older nodes; fascicles with a short peduncle bearing crowd-ed minute bracts, the lower sterile, the upper with flowers in their axils. Pedicels of male flowers fleshy (when fresh), c. 15-20 mm, sometimes with solitary or paired bracteoles, expanded above; receptacle at first globose with a terminal depression and an ostiole with 8 tepals in two double pairs, expanding to c. 18 mm ø before opening by 4-6 radial splits to form a star-shaped flower with the stamens fully exposed. Stamens numerous (over 100), inserted over the lower half of the receptacle, filament short; anthers to 1 mm long, opening by two longitudinal slits. Pedicels of female flowers shorter (c. 5 mm at anthesis); receptacle globose, smaller (c. 8 mm ø), tepals 4, the upper half of the receptacle becoming detached after anthesis by a circular scar. Carpels numerous (c. 50 or more), sessile on the lower half of the receptacle, with a short, blunt style. Receptacle becoming enlarged and fleshy in fruit.
