Eastern Tallerack

Eucalyptus extrica is a spreading mallee that typically grows to a height of 1–4 m (3 ft 3 in – 13 ft 1 in) and forms a lignotuber. It has smooth light grey over brown bark, sometimes with rough, fibrous or ribbony bark on the lower stems. Young plants and coppice regrowth have slightly glaucous, elliptical to egg-shaped leaves arranged in opposite pairs. Adult leaves are also arranged in opposite pairs, lance-shaped to egg-shaped, the same dull green on both sides, 70–140 mm (2.8–5.5 in) long and 20–50 mm (0.79–1.97 in) wide on a petiole 12–30 mm (0.47–1.18 in) long. The flower buds are arrange in leaf axils in groups of three on a flattened peduncle 6–20 mm (0.24–0.79 in) long, the individual buds on pedicels 6–13 mm (0.24–0.51 in) long. Mature buds are oval, 6–8 mm (0.24–0.31 in) long and 5–6 mm (0.20–0.24 in) wide with a rounded to flattened operculum. Flowering occurs between January and April and the flowers are whitish. The fruit is a woody, cylindrical to barrel-shaped capsule 13–21 mm (0.51–0.83 in) long and 10–22 mm (0.39–0.87 in) wide with the valves near to rim level. Tallerack (E. pleurocarpa) has a similar habit but has noticeably shorter, wider, glaucous leaves, glaucous buds and fruit. Intergrades between the two species have been recorded.

Eastern tallerack is found in coastal areas in the Goldfields-Esperance region of Western Australia between Esperance and Cape Arid where it grows in sandy soils over limestone.
