Shrubs, usually with much-branched stems, or small trees, the foliage lepidote. Leaves 
alternate, persistent; blades thick or leathery, usually broad, entire, undulate, or shallowly 
toothed, petioled. Flowers perfect, in cluster-like panicles in the axils of the leaves, the 
rachis sometimes slightly elongate. Calyx stellate; lobes 4-8, usually 5, mostly broad, rarely 
slightly elongate, much longer than the tube. Corolla white or pale, urceolate, exceeding the 
calyx, usually much longer, mostly nodding, the lobes much shorter than the tube. Stamens 
8-16, included; filaments narrow or slender above the dilated base, usually puberulent or 
pubescent, unappendaged; anthers oblong or oval, the sacs unappendaged. Ovary 4~8-celled, 
depressed or slightly elongate; style columnar or fusiform; stigma minute. Capsule longer 
than thick or subglobose, angled, with the sutures much thickened, 4~8-valved, septicidal.
