Description
Eucalyptus baueriana is a tree that grows to a height of about 20 metres (66 ft), sometimes a small tree or mallee to 12 metres (39 ft) high, and forms a lignotuber. It has persistent, light grey, fibrous or flaky bark with whitish patches, on the trunk and larger branches. The higher branches have smooth, grey bark that is shed in short ribbons. Young plants and coppice regrowth have broad egg-shaped to almost round leaves 35–60 mm (1.4–2.4 in) long and 39–80 mm (1.5–3.1 in) wide. Mature trees often have juvenile leaves in the crown. Adult leaves are egg-shaped, 53–105 mm (2–4 in) long and 23–52 mm (0.9–2 in) wide on a petiole 18–43 mm (0.71–1.7 in) long. The leaves are the same dull or glossy green colour on both sides and sometimes have a whitish bloom. The flowers are borne in groups of seven in leaf axils on an unbranched peduncle 5–11 mm (0.20–0.43 in) long, the individual buds on a pedicel 1–5 mm (0.039–0.20 in) long. Mature buds are oval to diamond-shaped, 3–6 mm (0.12–0.24 in) long and 3–4 mm (0.1–0.2 in) wide with a conical operculum. Flowering mainly occurs from September to December and the flowers are white. The fruit is a woody, conical capsule 4–7 mm (0.16–0.28 in) long and 4–7 mm (0.2–0.3 in) wide with the valves enclosed.[3][4][5][6]
E. baueriana Schauer subsp. baueriana is a tree to 20 metres (66 ft) with fruit 6–7 mm (0.2–0.3 in) long and 4–6 mm (0.2–0.2 in) wide;[11]
E. baueriana subsp. deddickensis Rule is a small tree or mallee to 12 metres (39 ft) with fruit 3–5 mm (0.1–0.2 in) long and 3–5 mm (0.1–0.2 in) wide and leaves 50–70 mm (2–3 in) long and 40–60 mm (2–2 in) wide;[12]
E. baueriana subsp. thalassina Rule, commonly known as Werribee blue box, is a small tree or mallee to 12 metres (39 ft) with fruit 3–5 mm (0.1–0.2 in) long and 3–5 mm (0.1–0.2 in) wide and leaves 30–50 mm (1–2 in) long and 20–40 mm (0.8–2 in) wide.[13]
Subspecies deddickensis is restricted to two isolated population on the banks of the Deddick River in far north-eastern Victoria and subspecies thalassina to the Werribee River catchment near Bacchus Marsh.[15][16]
