Angophora melanoxylon

Angophora melanoxylon is a tree that typically grows to a height of 15 m (49 ft) and forms a lignotuber. It has rough, fibrous, greyish bark on the trunk and branches. Young plants and coppice regrowth have sessile, lance-shaped, stem-clasping leaves that are 45–100 mm (1.8–3.9 in) long and 12–25 mm (0.5–1.0 in) wide and arranged in opposite pairs. Adult leaves are also arranged in opposite pairs, dull grey-green to green but paler on the lower surface, linear to narrow lance-shaped or narrow elliptical, 30–90 mm (1.2–3.5 in) long and 6–22 mm (0.2–0.9 in) wide either with a stem-clasping base or on a petiole up to 10 mm (0.4 in) long. The flower buds are arranged on the ends of branchlets on a branched peduncle 6–23 mm (0.2–0.9 in) long, each branch of the peduncle with three or seven buds on pedicels 3–9 mm (0.12–0.35 in) long. Mature buds are globe-shaped, 4–6 mm (0.16–0.24 in) long and 4–7 mm (0.16–0.28 in) wide with longitudinal ribs on the floral cup. The petals are white or creamy white with a green keel, 3–4 mm (0.12–0.16 in) long and wide. Flowering has been observed in December and the fruit is a woody cup-shaped, cylindrical or barrel-shaped capsule 8–13 mm (0.3–0.5 in) long and 7–11 mm (0.3–0.4 in) wide with the valves enclosed in the fruit.

Coolabah apple grows in deep, sandy soils and occurs sporadically in dry areas between Pilliga, Coolabah and Bourke in New South Wales and Cunnamulla, Augathella and St George in Queensland.
