Scientific classification

Eucalyptus melanoxylon, commonly known as black morrell, is a species of small to medium-sized tree that is endemic to Western Australia. It has hard, fissured bark on some or all of its trunk, linear to narrow lance-shaped leaves, flower buds in groups of between seven and fifteen, white flowers and conical to cup-shaped fruit.


Eucalyptus melanoxylon is a tree that typically grows to a height of 4–24 m (13–79 ft), sometimes a robust mallee, and forms a lignotuber. It has hard, thick, fissured bark on the trunk and larger branches or sometimes only on the lower half, and white to greyish bark above. Young plants and coppice regrowth have dull greenish leaves that are lance-shaped, 40–75 mm (1.6–3.0 in) long and 12–30 mm (0.47–1.18 in) wide. Adult leaves are the same glossy green on both surfaces, linear to narrow lance-shaped, 72–110 mm (2.8–4.3 in) long and 7–12 mm (0.28–0.47 in) wide on a petiole 7–15 mm (0.28–0.59 in) long. The flower buds are arranged in groups of between seven and fifteen on an unbranched peduncle 8–15 mm (0.31–0.59 in) long, the individual buds on pedicels 3–5 mm (0.12–0.20 in) long. Mature buds are oval, 5–8 mm (0.20–0.31 in) long and 3–5 mm (0.12–0.20 in) wide with a conical to rounded operculum. Flowering occurs between November and March and the flowers are white. The fruit is a woody conical to cup-shaped capsule 4–6 mm (0.16–0.24 in) long and 5–6 mm (0.20–0.24 in) wide with the valves protruding.


Eucalyptus melanoxylon was first formally described in 1923 by Joseph Maiden in his book, A Critical Revision of the Genus Eucalyptus from specimens collected near Westonia.

Distribution and habitat

Black morrell occurs in southern Western Australia from Westonia, Bullabulling and Lake King in the eastern wheatbelt to Balladonia in the eastern goldfields. It is found in depressions and on flats where it grows in sand-clay-loamy soils.
