Eucalyptus Gunni

Eucalyptus gunnii is a tree that typically grows to a height of 35 m (115 ft) and forms a lignotuber. It has smooth, mottled, white or grey bark, sometimes with persistent rough bark on the lower trunk. Young plants and coppice regrowth have sessile leaves arranged in opposite pairs. Juvenile stems can be rounded or square in cross section. The juvenile leaves are heart-shaped to more or less round, greyish green or glaucous, 13–45 mm (0.51–1.77 in) long and 17–40 mm (0.67–1.57 in) wide. Adult leaves are arranged alternately, lance-shaped to egg-shaped, the same dull greyish to bluish green on both sides, 40–90 mm (1.6–3.5 in) long and 12–35 mm (0.47–1.38 in) wide on a petiole 9–23 mm (0.35–0.91 in) long. The flowers are arranged in leaf axils in groups of three on an unbranched peduncle 3–9 mm (0.12–0.35 in) long, the individual buds sessile or on a pedicels up to 4 mm (0.16 in) long. Mature buds are oval, 5–9 mm (0.20–0.35 in) long and 3–5 mm (0.12–0.20 in) wide with a conical, rounded or flattened operculum. It flowers in most months and the flowers are white. The fruit is a woody cylindrical to barrel-shaped capsule 5–9 mm (0.20–0.35 in) long and 5–7 mm (0.20–0.28 in) wide with the valves near rim level or enclosed.
