Description
Chionanthus ramiflorus is an evergreen shrub or tree that can reach up to 23 m (75 ft) in height. The trunk and branches are pale, the leafy twigs are circular in cross section. The glossy green leaves are usually about 8 to 20 cm (3.1 to 7.9 in) long and 4 to 7 cm (1.6 to 2.8 in) wide, and elliptic to oblong-elliptic. They are attached to the twig with a petiole up to 5 cm (2.0 in) long and they have 7–10 lateral veins on either side of the midrib.[4][5][6]
The inflorescence is a panicle up to 12 cm (4.7 in) long. They carry numerous small white or yellow flowers, each of which have four petals about 2.5 mm (0.10 in) long. The fruit is a blue-black, ovoid drupe about 25 mm (1.0 in) long and 15 mm (0.6 in) diameter.[4][5]

Taxonomy
It was originally described by Scottish botanist William Roxburgh in 1820, but since then numerous authors have put forward many alternate names, resulting in numerous synonyms now being recognised.[3]
Conservation
The International Union for Conservation of Nature (IUCN) assessed this species in 2024, giving it a status of least concern. In its statement, the IUCN cites the plant's large numbers and wide distribution, as well as the absence of any discernable threats, as the basis for its evaluation.[1]
Ecology
The fruit of this plant is eaten by cassowaries, figbirds, koels, Torres Strait pigeons,[6][9] and golden bowerbirds.[10] The leaves are eaten by Lumholtz's tree-kangaroos.[9]
