Description Edit
Phebalium laevigatum is an erect, slender shrub that typically grows to a height of 0.35–1.2 m (1 ft 2 in – 3 ft 11 in). Its branchlets are glandular-warty and the leaves are linear to narrow oblong, mostly 12–15 mm (0.47–0.59 in) long and 1.5–2 mm (0.059–0.079 in) wide on a petiole about 2 mm (0.079 in) long, mostly glabrous on the upper surface and covered with silvery scales on the lower surface. The flowers are white or yellow and borne in umbels of about seven, each flower on a pedicel about 4 mm (0.16 in) long. The five sepals are about 1.5 mm (0.059 in) long, joined for half their length and covered with rust-coloured scales on the outside. The petals are broadly elliptical, 4–5 mm (0.16–0.20 in) long and 2.5–3.5 mm (0.098–0.138 in) wide, covered with rust-coloured scales on the outside. Flowering occurs from June to October.[2][3][4]
