Eucalyptus pleurocarpa, commonly known as tallerack, talyerock or tallerack is a species of mallee that is endemic to the southwest of Western Australia. It has smooth bark, broadly lance-shaped to elliptical, grey or glaucous leaves that are arranged more or less in opposite pairs, flower buds in groups of seven, whitish flowers and glaucous, barrel-shaped fruit. It is easily recognised in the field by its form, large, white, waxy leaves and, when in flower, its stamens clustered in four groups.
Eucalyptus pleurocarpa is a mallee that typically grows to 2–5 m (6 ft 7 in – 16 ft 5 in) high, 3–6 m (9.8–19.7 ft) wide and forms a lignotuber and has smooth bark. It has a spreading to erect, straggly habit with many thin stems with smooth, greyish bark. The foliage is thick, leathery and waxy with a bluish grey colour and the flower buds, fruit and stems are white and waxy. Young plants and coppice regrowth have stems that are square in cross-section with a wing on each corner, egg-shaped to oblong or elliptical to heart-shaped, 100–120 mm (3.9–4.7 in) long and 60–65 mm (2.4–2.6 in) wide, petiolate and arranged in opposite pairs. Adult leaves are very similar to the juvenile leaves, arranged more or less in opposite pairs, the same dull greyish green on both sides, broadly lance-shaped to egg-shaped or elliptical, 45–140 mm (1.8–5.5 in) long and 25–70 mm (0.98–2.76 in) wide on a petiole 8–20 mm (0.31–0.79 in) long. The flower buds are arranged in leaf axils in groups of three on a flattened, unbranched peduncle 6–18 mm (0.24–0.71 in) long, the individual buds on pedicels 2–8 mm (0.079–0.315 in) long. Mature buds are oval, 8–13 mm (0.31–0.51 in) long and 5–9 mm (0.20–0.35 in) wide with a four-sided floral cup, a rounded operculum and the stamens in four clusters. Flowering occurs from January to April or from October to December and the flowers are whitish. The fruit is a woody, barrel-shaped to cubic, four-angled capsule 12–22 mm (0.47–0.87 in) long and 14–20 mm (0.55–0.79 in) wide.
