Eucalyptus horistes

Eucalyptus horistes is a mallee or small tree that typically grows to a height of 8–12 m (26–39 ft) and forms a lignotuber. It has smooth greyish bark, often with rough, firm fibrous bark on the base or all of the trunk. Young plants and coppice regrowth have sessile, heart-shaped, more or less round or elliptic leaves 10–45 mm (0.39–1.77 in) long and 8–30 mm (0.31–1.18 in) wide. Adult leaves are glossy green, narrow lance-shaped to elliptic, 45–95 mm (1.8–3.7 in) long and 4–15 mm (0.16–0.59 in) wide on a petiole 4–15 mm (0.16–0.59 in) long. The flower buds are arranged in leaf axils in groups of seven, nine, eleven or thirteen on an unbranched peduncle 2–13 mm (0.079–0.512 in) long, the individual buds on pedicels 1–4 mm (0.039–0.157 in) long. Mature buds are oval to spindle-shaped, 5–10 mm (0.20–0.39 in) long and 2–4 mm (0.079–0.157 in) wide with a beaked operculum. Flowering occurs from November to December or January and the flowers are creamy white. The fruit is a woody, short cylindrical to shortened spherical capsule 3–7 mm (0.12–0.28 in) long and 4–6 mm (0.16–0.24 in) wide with the valves near rim level.
