Petiole 1-8 mm long, channelled, tomentose, pubescent, appressed puberulous or glabrous. Fascicles 1-30-flowered. Pedicel 1-3(-3.5) mm long, tomentose, pubescent or appressed puberulous. Flowers bisexual. Sepals five, 0.5-1 mm long, ovate, triangular or suborbicular, apex acute to rounded, outside tomentose, pubescent or appressed puberulous, often with a broad hyaline glabrous margin, inside appressed puberulous or glabrous.

Stamens (4-)5(-6), fixed at the top of the corolla tube or base of the lobes; filaments 2-5 mm long, glabrous; anthers 0.3-0.6 mm long, broadly ovoid or oblong, glabrous. Ovary ovoid to globose, five(-six)-locular, appressed puberulous; style 0.1-0.5 mm long after anthesis, glabrous; style-head usually minutely lobed. Fruit 0.5-1.1 cm long, 4-7 mm broad, narrowly to broadly ellipsoid or subglobose, apex and base rounded or tapering, smooth, glabrous; pericarp fleshy. Seed solitary, 4.5-8 mm long, ellipsoid with an obliquely truncated base, not or only slightly laterally compressed; testa smooth, shining, usually prominently sculptured on the adaxial face, 0.1-1 mm thick; scar broad, short, often cordate, basi-ventral; embryo with thin foliaceous cotyledons and exserted radicle, surrounded by copious endosperm.
