About Angophora leiocarpa (L.A.S.Johnson ex G.J.Leach) K.R.Thiele & Ladiges
Angophora leiocarpa is a tree that typically grows to a height of 25 metres (82 feet) and forms a lignotuber. Its bark is smooth, ranges in colour from pink to orange or greyish, and is shed in small patches. Young plants and coppice regrowth have sessile narrow lance-shaped leaves that measure 45–140 mm (1.8–5.5 in) long and 7–28 mm (0.3–1.1 in) wide, with a stem-clasping base, and are arranged in opposite pairs. Adult leaves are also arranged in opposite pairs, and are lance-shaped or curved, measuring 55–160 mm (2.2–6.3 in) long and 6–25 mm (0.2–1.0 in) wide, tapering to a petiole 6–15 mm (0.2–0.6 in) long. Flower buds are arranged at the ends of branchlets on a branched, glabrous peduncle 9–32 mm (0.4–1.3 in) long. Each branch of the peduncle holds three, rarely seven buds, attached to pedicels 3–8 mm (0.1–0.3 in) long. Mature buds are globe-shaped, 4–7 mm (0.2–0.3 in) long and 4–6 mm (0.16–0.24 in) wide, with a smooth to slightly ribbed floral cup. Petals on mature buds are about 3 mm (0.1 in) long and 3–4 mm (0.12–0.16 in) wide. Flowering has been observed from November to February. The fruit is a thin-walled, barrel-shaped to cup-shaped capsule 10–15 mm (0.4–0.6 in) long and 7–12 mm (0.3–0.5 in) wide, with valves enclosed inside the fruit. This species grows in open forest on sandstone hills and outcrops, ranging from Blackall and Mackay in Queensland, south to Narrabri and Grafton in New South Wales.
