Eucalyptus laeliae, commonly known as the Darling Range ghost gum or butter gum, is a species of small to medium-sized tree occurring only on the western side of the Darling Range. It has smooth white, powdery bark, lance-shaped adult leaves, flower buds in groups of between seven and eleven, creamy white flowers and cup-shaped to barrel-shaped fruit.

Eucalyptus laeliae is a tree that typically grows to a height of 5 to 20 metres (16 to 66 ft) and forms a lignotuber. The bark is smooth, powdery, usually white but in autumn, butter yellow. Young plants and coppice regrowth have bluish green, egg-shaped to lance-shaped leaves that are 65–125 mm (2.6–4.9 in) long and 23–45 mm (0.91–1.77 in) wide. Adult leaves are arranged alternately, the same dull bluish green or yellowish on both sides, lance-shaped to curved, 85–135 mm (3.3–5.3 in) long and 10–25 mm (0.39–0.98 in) wide on a petiole 8–20 mm (0.31–0.79 in) long.

The flower buds are arranged in leaf axils in groups of seven, nine or eleven on an unbranched peduncle 8–15 mm (0.31–0.59 in) long, the individual buds on pedicels 2–3 mm (0.079–0.118 in) long. Mature buds are oval or club-shaped, 6–7 mm (0.24–0.28 in) long and 3–5 mm (0.12–0.20 in) wide with a rounded operculum with a small point on the top. Flowering occurs between December and February and the flowers are creamy white or white, soft and bristly. The fruit is a woody, cup-shaped or barrel-shaped capsule 5–7 mm (0.20–0.28 in) long and 4–6 mm (0.16–0.24 in) wide with the disc descending and the valves near rim level.

Taxonomy and naming

Eucalyptus laeliae was first formally described by the botanists Francis Podger and George Chippendale in 1969 in the Journal of the Royal Society of Western Australia. The type specimen was collected by Leslie McGann near North Dandalup in 1966. The species name laeliae is taken from the names of one of the vestal virgins, referring to the smooth, column-like trunk.

Distribution and habitat

The Darling Range ghost gum is found on hills and amongst granite outcrops along the west coast in the Peel and South West regions of Western Australia between Kalamunda in the north, Wandering to the east and Capel to the south where it grows in sandy-clay-loam soils.

Use in horticulture

The tree can be bought commercially as a seedling or as seeds. It grows well in full sun in a range of well-drained soil types. It can be susceptible to leaf blister, a form of insect attack.

Conservation status

This eucalypt is classified as "not threatened" in Western Australia by the Western Australian Government Department of Parks and Wildlife.
