Description

Phebalium megaphyllum is an erect, rounded shrub that typically grows to a height of 0.4–2 m (1 ft 4 in – 6 ft 7 in). Its branchlets are glandular-warty and the leaves are linear oblong to wedge-shaped, 7–15 mm (0.28–0.59 in) long and 2–4 mm (0.079–0.157 in) wide on a short petiole. The upper surface is glabrous with a central groove and the lower surface is covered with silvery scales and has a prominent, warty mid-vein. The flowers are white and borne in umbels of three to six, each flower on a pedicel 4–6 mm (0.16–0.24 in) long. The five sepals are 3.5–4.5 mm (0.14–0.18 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 silvery or rust-coloured scales. Flowering occurs from September to November. [2] [3]

[4] [5] In 1998, Paul G. Wilson changed the name to Phebalium megaphyllum, publishing the change in the journal Nuytsia . [6] [7]

Distribution and habitat

Phebalium megaphyllum grows in scrub on undulating plains, ironstone hills and breakaways between Mullewa, Coolgardie and Ravensthorpe. [2] [3]

Conservation status

This phebalium is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [2]
