Eucalyptus scopulorum is a species of small tree that is endemic to a small area of northern New South Wales. It has rough ironbark on the trunk and branches, lance-shaped adult leaves, flower buds in groups of seven, white flowers and barrel-shaped or conical fruit.

Description

Eucalyptus scopulorum is a tree that typically grows to a height of 8 m (26 ft) and forms a lignotuber. It has soft, corky, pale grey bark on the trunk and branches. Young plants and coppice regrowth have stems that are more or less square in cross-section and dull greyish green leaves that are egg-shaped, 35–110 mm (1.4–4.3 in) long and 25–50 mm (0.98–1.97 in) wide. Adult leaves are the same shade of dull green on both sides, lance-shaped to broadly lance-shaped, 60–110 mm (2.4–4.3 in) long and 15–38 mm (0.59–1.50 in) wide, tapering to a petiole 8–25 mm (0.31–0.98 in) long. The flower buds are arranged on the ends of branchlets in groups of seven on a branched peduncle 7–15 mm (0.28–0.59 in) long, the individual buds on pedicels 6–9 mm (0.24–0.35 in) long. Mature buds are oval to diamond-shaped, 7–9 mm (0.28–0.35 in) long and about 4 mm (0.16 in) wide with a conical operculum. Flowering has been recorded in October and the flowers are white. The fruit is a woody barrel-shaped or conical capsule 6–9 mm (0.24–0.35 in) long and 5–7 mm (0.20–0.28 in) wide with the valves below rim level.[2][3][4]

Taxonomy and naming

Eucalyptus scopulorum was first formally described in 1997 by Ken Hill in the journal Telopea from specimens he collected in the Gibraltar Range State Forest in 1996.[4][5] The specific epithet (scopulorum) is from the Latin word scopulus meaning "a cliff", referring to the usual habitat of this species.[4]

Distribution and habitat

This eucalypt grows in rocky crevices on steep cliffs and is only known in a few places on the Gibraltar Range.[4]
