Description

Eucalyptus amplifolia is a tree that can grow to 30 m (100 ft) in height in forest situations, though it is often shorter in sparser woodland areas. It has smooth, often blotchy, white, cream, yellow, grey, pink or blue-grey bark throughout the trunk and branches, usually with loose, flaking grey slabs persistent at the base and lower trunk. The leaves on young plants are rounded, egg-shaped or triangular, green, 50–220 mm (2–9 in) long, 35–180 mm (1–7 in) and predominately held horizontal to the ground. Adult leaves are arranged alternately, broadly lance-shaped, 75–250 mm (3–10 in) long and 16–70 mm (0.6–3 in) wide on a petiole 10–30 mm (0.4–1 in) long. Side-veins are 45° or greater to the midrib, and the leaves are of a dull or glossy green of the same hue both sides of the leaf. [3] [4] [5]

The flowers are arranged in groups of seven to fifteen or more, the groups on a flattened or angular peduncle 7–15 mm (0.3–0.6 in) long, the individual flowers sometimes on a pedicel up to 8 mm (0.3 in) long, or sessile. The buds are cone-shaped, the floral cup hemispherical 2–3 mm (0.08–0.1 in) long, the operculum conical, 7–9 mm (0.3–0.4 in) long and about 4 mm (0.2 in) wide at the join. Flowering occurs between November and January and the fruit is a woody, hemispherical capsule 2–5 mm (0.08–0.2 in) long and 4–6 mm (0.16–0.24 in) wide on a pedicel 1–5 mm (0.04–0.2 in) long. There are three or four upward-pointing valves on the top of the fruit. [3] [4] [5]

Taxonomy and naming

Eucalyptus amplifolia was first formally described in 1891 by Charles Victor Naudin who published the description in Description and emploi des Eucalyptus: introduits en Europe principalement en France et en Algerie: second memoire. [2] The specific epithet (amplifolia) is derived from the Latin words amplus meaning "large" [6] :86 and folium meaning "leaf", [6] :466 referring to the large leaves of this eucalypt. [4]

In 1990, Lawrie Johnson and Ken Hill described two subspecies of Eucalyptus amplifolia: [7]

Distribution and habitat

Cabbage gum grows in grassy woodland and forest, often in depressions and on river flats. [3] [5]
