Flowers white, the tube only 0.5-1mm long, with the lobes spreading and to 2 mm long; spring to early summer, mostly Dec. Stamens protruding. Fruit to about 5 mm long, black.

In Melbourne, plants with smaller, darker and more narrow leaves with pronounced wavy edges have been referred to L. undulatum Blume,Wavy-leaved Privet, from New Guinea; it appears that at least some of these are referable to L. sinense.
