Eucalyptus sheathiana, commonly known as ribbon-barked gum, is a species of tree or a mallee that is endemic to Western Australia. It has smooth bark that is shed in long ribbons, lance-shaped adult leaves, flower buds in groups of seven, creamy white flowers and conical to cup-shaped fruit.
Eucalyptus sheathiana is a tree or a mallee, that typically grows to a height of 3–15 m (9.8–49.2 ft) and forms a lignotuber. It has smooth, greyish bark that is shed in long ribbons. Young plants and coppice regrowth have greyish green, egg-shaped to lance-shaped leaves that are 75–125 mm (3.0–4.9 in) long and 25–40 mm (0.98–1.57 in) wide. Adult leaves are lance-shaped, 75–135 mm (3.0–5.3 in) long and 8–18 mm (0.31–0.71 in) wide, tapering to a petiole 10–28 mm (0.39–1.10 in) long. The flower buds are arranged in leaf axils on an unbranched peduncle 5–20 mm (0.20–0.79 in) long, the individual buds on pedicels 3–7 mm (0.12–0.28 in) long. Mature buds are oval to pear-shaped, 6–12 mm (0.24–0.47 in) long and 4–7 mm (0.16–0.28 in) wide with a conical operculum. Flowering occurs from January to April and the flowers are creamy white. The fruit is a woody conical to cup-shaped capsule 5–10 mm (0.20–0.39 in) long and 5–8 mm (0.20–0.31 in) wide with the valves near rim level.
Taxonomy and naming
Eucalyptus sheathiana was first formally described in 1916 by Joseph Maiden from material collected in Kings Park by Jeremiah Sheath (1850–1915), in turn, from seed collected from the "Eastern Gold Fields near the South Australian border". The specific epithet (sheathiana) honour the collector of the type specimens.
