Characteristics

Shrub or small tree. Leaves subsessile, glossy, rather coriaceous, ± cordate at the base; stipules interpetiolar, broadly triangular, apiculate. Flowers strongly sweetly scented, in apparently but not quite terminal and axillary panicles, the ultimate components dense and supported by small stipule-like triangular bracts; each flower supported by 2 ovate keeled bracteoles at the base of the calyx. Calyx-tube campanulate, the limb-tube exceeding the ovary, pubescent inside; lobes very transverse and rounded-truncate, usually 4 small ones in 2 contiguous pairs and 2 large ones or sometimes only 4–5, imbricate. Corolla white; tube narrowly funnel-shaped, with matted hairs inside save for the basal 1.5 mm.; lobes 6–7(–8), oblong-elliptic. Anthers linear, exserted for 2/3 or more of their length, apiculate. Disc annular, fleshy. Ovary thick-walled, with 1–2 small locules; ovules solitary, pendulous from a thickened funicle; style narrowly club-shaped, ± densely pubescent save at extreme base, the 2 arms ± fused but separable into flattened lobes for slightly over half its length. Fruit subglobose, presumably fleshy, crowned by the persistent calyx-limb. Seeds ovoid, very strongly ruminate, the exterior resembling hanks of rope, each longitudinal piece closely striated.
