Eucalyptus tricarpa, commonly known as red ironbark [2] or mugga ironbark, [3] is a species of tree that is endemic to south-eastern Australia. It has thick, rough ironbark on the trunk and branches, lance-shaped adult leaves, flower buds usually in groups of three, white flowers and cylindrical or spherical fruit.
Eucalyptus tricarpa is a tree that typically grows to a height of 35 m (115 ft) and forms a lignotuber. It has thick rough, reddish brown to black ironbark on the trunk and branches. Young plants and coppice regrowth have green to greyish, elliptical to lance-shaped leaves that are 40–110 mm (1.6–4.3 in) long and 13–30 mm (0.51–1.18 in) wide and petiolate. Adult leaves are arranged alternately, the same shade of green to greyish green on both sides, lance-shaped to curved, 80–220 mm (3.1–8.7 in) long and 10–26 mm (0.39–1.02 in) wide, tapering to a petiole 10–30 mm (0.39–1.18 in) long. The flower buds are arranged in leaf axils in groups of three, sometimes seven, on an unbranched peduncle 8–15 mm (0.31–0.59 in) long, the individual buds on pedicels 5–18 mm (0.20–0.71 in) long. Mature buds are oval, 10–15 mm (0.39–0.59 in) long and 6–9 mm (0.24–0.35 in) wide with a conical to beaked operculum. Flowering occurs from February to November and the flowers are white or pale pink. The fruit is a woody cylindrical to shortened spherical capsule 8–13 mm (0.31–0.51 in) long and 8–15 mm (0.31–0.59 in) wide with the valves enclosed below the rim. [2] [3] [4] [5]
The red ironbark was first formally described in 1962 by Lawrie Johnson who gave it the name Eucalyptus sideroxylon subsp. tricarpa and published the description in Contributions from the New South Wales National Herbarium. [6] In 1991, Johnson and Ken Hill raised the subspecies to species level as E. tricarpa. [7] The specific epithet (tricarpa) is from ancient Greek words meaning "three" and "fruit". [2]
In 2004, Kevin James Rule described two subspecies and the names are accepted by the Australian Plant Census:
Eucalyptus tricarpa grows in forest and woodland in coastal south from Araluen in New South Wales and is common in the goldfields near Bendigo, near Anglesea and in coastal and near-coastal areas of Gippsland. Subspecies decora occurs in open woodland around St Arnaud in Victoria.

The Noongar names for the tree are colaille, gooloorto, koolert and moitch. This tree has rough, fibrous bark on the trunk and large branches, smooth greyish bark above, lance-shaped to curved adult leaves, flower buds in groups of between seven and eleven, white flowers and bell-shaped, cup-shaped or hemispherical fruit.
Eucalyptus radiata, commonly known as the narrow-leaved peppermint or Forth River peppermint, is a species of tree that is endemic to south-eastern Australia. It has rough, fibrous to flaky bark on the trunk and larger branches, smooth grey bark on the thinner branches, lance-shaped to curved or almost linear leaves, flower buds in groups of eleven to twenty or more, white flowers and cup-shaped, hemispherical or shortened spherical fruit.
Eucalyptus leucoxylon, commonly known as yellow gum, blue gum or white ironbark, is a species of small to medium-sized tree that is endemic to south-eastern continental Australia. It has smooth yellowish bark with some rough bark near the base, lance-shaped or curved adult leaves, flower buds in groups of three and cylindrical, barrel-shaped or shortened spherical fruit. A widely cultivated species, it has white, red or pink flowers.
Eucalyptus polyanthemos, commonly known as red box, is a species of small to medium-sized tree, that is native to eastern Australia but has been introduced into other countries.
