Flowers fragrant, hermaphrodite, sessile and appearing terminal on short leafless spurs (but actually axillary pairs with very reduced internodes) or sometimes pedicellate (referred to as pedunculate by some authorities) in pairs from the axils of young leaves, 5-merous or sometimes 4–8-merous; bracts/bracteoles brown and papery when dry.
Ovary 2-locular; ovules 2–10, pendulous in 2 rows from a small fleshy placenta; style slender, pubescent or with very few hairs; pollen presenter fusiform, entirely bifid, but usually cohering save at the apex, sparsely pubescent to pubescent.
Corolla white to pink; tube funnel-shaped above, cylindrical below, glabrous to pubescent outside, pubescent at throat; lobes ± oblong, usually slightly exceeding the tube, spreading to reflexed, overlapping to the left in bud.
Stamens inserted at the throat, anthers sessile, attached one third of the length from the base.
Calyx tube narrowly ovoid; limb-tube ± obsolete; lobes linear-lanceolate to lanceolate.
Leaves opposite; stipule limbs usually ovate, brown and papery when dry.
Shrubs, usually hairy at the extremities or less often glabrous.
Fruit globose, fleshy; calyx lobes eventually deciduous.
Seeds compressed, with finely reticulate testa.
Disk annular.
