About Persoonia arborea F.Muell.
Persoonia arborea is a large shrub or small tree that usually reaches a height of 3–14 metres (9.8–45.9 feet). Its young branchlets are densely covered with greyish to rust-coloured hairs. The leaves are narrow spatula-shaped to lance-shaped, with the narrower end located towards the base. They measure 40–100 millimetres (1.6–3.9 inches) long and 6–21 millimetres (0.24–0.83 inches) wide.
Flowers grow singly in the axils of leaves, on a pedicel that is up to 5 millimetres (0.20 inches) long. The tepals are 16–20 millimetres (0.63–0.79 inches) long, hairy on the outside, with a 1–2 millimetre (0.039–0.079 inch) long spine at the end, and the anthers are white. Flowering takes place from December to March. The fruit is a yellowish green, oval drupe that grows up to about 14 millimetres (0.55 inches) long and 12 millimetres (0.47 inches) wide.
This species, commonly called tree geebung, occurs in high-rainfall mountain ash forest northeast of Melbourne, at altitudes between 450 and 1,200 metres (1,480–3,940 feet). It is listed as vulnerable on the Advisory List of Rare Or Threatened Plants In Victoria maintained by the Department of Sustainability and Environment. It is relatively common within its limited range, and is capable of colonising disturbed areas. Around 40% of its habitat is within the Yarra Ranges National Park, and the remaining 60% is on public land used for logging.
