Description

Eucalyptus quadrans is a mallee that typically grows to a height of 5 m (16 ft), rarely a tree to 12 m (39 ft), and forms a lignotuber. It has smooth greyish bark, sometimes with rough, flaky or scaly bark near the base of the trunk. Young plants and coppice regrowth have greyish green, linear leaves that are 30–70 mm (1.2–2.8 in) long and 2–6 mm (0.079–0.236 in) wide. Adult leaves are the same shade of glossy dark green on both sides, narrow lance-shaped, 55–105 mm (2.2–4.1 in) long and 5–15 mm (0.20–0.59 in) wide, tapering to a petiole 5–16 mm (0.20–0.63 in) long. The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle 4–13 mm (0.16–0.51 in) long, the individual buds on pedicels 2–5 mm (0.079–0.197 in) long. Mature buds are oval to pear-shaped and square in cross-section, 5–7 mm (0.20–0.28 in) long and 3–6 mm (0.12–0.24 in) wide with a hemispherical operculum. Flowering occurs from August to November and the flowers are white. The fruit is a woody, cup-shaped capsule that is square in cross-section, 6–9 mm (0.24–0.35 in) long and 4–7 mm (0.16–0.28 in) wide with the valves enclosed below rim level.
