Angophora costata subsp. costata is a species of medium-sized to large tree that is endemic to eastern Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of three, white or creamy white flowers and cylindrical to barrel-shaped fruit. It is similar to subspecies costata but has narrower leaves and smaller fruit.
Angophora costata subsp. costata is a tree that typically grows to a height of 30 m (98 ft) and forms a lignotuber. It has smooth pinkish to orange bark that weathers to grey. Young plants and coppice regrowth have sessile leaves with a stem-clasping base that are elliptical to egg-shaped, 60–125 mm (2.4–4.9 in) long, 20–65 mm (0.79–2.56 in) wide and arranged in opposite pairs. Adult leaves are also arranged in opposite pairs, glossy green above and paler below, lance-shaped or curved, 70–190 mm (2.8–7.5 in) long and 12–35 mm (0.47–1.38 in) wide on a petiole 9–25 mm (0.35–0.98 in) long. The flower buds are arranged on the ends of branches on a branched peduncle 3–20 mm (0.12–0.79 in) long, each branch of the peduncle usually with three buds on pedicels 3–8 mm (0.12–0.31 in) long. Mature buds are globe-shaped, 4–8 mm (0.16–0.31 in) long and 5–7 mm (0.20–0.28 in) wide, the floral cup glabrous with longitudinal ribs. The sepals are up to 3 mm (0.12 in) long. The petals are white with a green keel and 3–4 mm (0.12–0.16 in) long and wide. Flowering occurs from October to December. The fruit is a cylindrical to barrel-shaped capsule 10–18 mm (0.39–0.71 in) long and 9–17 mm (0.35–0.67 in) wide on a pedicel 2–12 mm (0.079–0.472 in) long.[2][3][4][5]
