Flowers dioecious, female or functionally male, borne in small pseudo-racemes which develop into leafy twigs, pendulous. 5-10 mm long, pentamerous, urceolate with spreading eventually reflexed corolla, creamy white; peduncle 0.5-2 cm long, densely hairy with ferruginous one-celled hairs mixed with many-celled short gland-tipped hairs which also occur on the calyx and bracts; bracts 2, separated by an internode, lanceolate to ovate-cordate, subsessile, often glabrous above and hairy below with the margins fimbriate, early deciduous. Calyx urceolate, densely hairy, shortly 5-lobed at apex of tube. Corolla deeply 5-lobed, campanulate, with lobes reflexed, thinly hairy outside and on inner surface at apex of lobes; lobes about equal to the tube. Ovary conical, hairy with a mixture of one-celled hairs and short glandular many-celled hairs, 4-6-celled with one ovule in each cell. Fruit subglobose, up to 2 cm in diam., glabrescent, red, completely enclosed in the inflated bladder-shaped calyx. Seeds 2-4 per fruit, pale brown, 8 mm long, circumvented by a thin line.
A shrub or small tree 5-7 m in height; occurring in scrub and forest. Bark: grey to almost black, smooth; branchlets greenish or pinkish, densely covered with fine rust-coloured hairs.
