Description
editPhebalium tuberculosum is an erect shrub that typically grows to a height of 0.3–4.0 m (1 ft 0 in – 13 ft 1 in) with glandular-warty branchlets, leaves and sepals. The leaves are oblong with the edges rolled under, appearing more or less cylindrical, and are about 4–7 mm (0.16–0.28 in) long and about 1 mm (0.039 in) wide. The flowers are borne in umbels of three or four, each flower on a thick pedicel 2–5 mm (0.079–0.197 in) long covered with rust-coloured scales. The five sepals are 2–3 mm (0.079–0.118 in) long, joined at the base. The petals are white, broadly elliptical, 3–4.5 mm (0.12–0.18 in) long and 2–3.5 mm (0.079–0.138 in) wide, with silvery to rust-coloured scales on the back. Flowering occurs from September to December.[2][3][4]

The following year, George Bentham changed the name to Phebalium tuberculosum, publishing the change in Flora Australiensis.[7][8]
