Eucalyptus dives, commonly known as the broad-leaved peppermint or blue peppermint, [2] is a species of tree that is endemic to south-eastern Australia. It has rough, finely fibrous bark on the trunk and larger branches, smooth bark above, lance-shaped or curved adult leaves, flower buds in groups of eleven or more, white flowers and cup-shaped, hemispherical or conical fruit.
Eucalyptus dives is a tree that grows to a height of 20 m (66 ft) and forms a lignotuber. The bark on the trunk and larger branches is rough, finely fibrous and greyish and smooth grey on the thinner branches. Young plants and coppice regrowth have leaves arranged in opposite pairs, egg-shaped to heart-shaped or curved, 60–140 mm (2.4–5.5 in) long and 20–70 mm (0.79–2.76 in) wide and sessile. Adult leaves are arranged alternately, lance-shaped to curved, the same slightly glossy or dull green on both sides, 70–150 mm (2.8–5.9 in) long and 14–42 mm (0.55–1.65 in) wide on a petiole 5–33 mm (0.2–1 in) long. The flower buds are usually arranged in groups of eleven or more in leaf axils on an unbranched peduncle 3–13 mm (0.1–0.5 in) long, the individual buds on a pedicel 2–7 mm (0.08–0.3 in) long. Mature buds are oval to club-shaped, 3–6 mm (0.12–0.24 in) long and 2–4 mm (0.079–0.157 in) wide with a conical to rounded operculum. Flowering occurs from September to January and the flowers are white. The fruit is a woody, cup-shaped, hemispherical or conical capsule, 3–7 mm (0.12–0.28 in) long and 4–8 mm (0.16–0.31 in) wide and sessile or on a pedicel up to 5 mm (0.20 in) long with the valves near the level of the rim.

Eucalyptus dives was first formally described in 1843 by Johannes Conrad Schauer and the description was published in Walpers' book Repertorium Botanices Systematicae (Volume 2). [6] [7] The specific epithet (dives) is a Latin word meaning "rich" [8] referring to the rich oil content of the leaves. [2]
Broad-leaved peppermint usually grows in poor, dryish soils in open forest and woodland, usually in poor, shallow, stony soils in higher places. It is found in New South Wales south from Niangala in New South Wales and in south-eastern Victoria.
This eucalypt is a source of Eucalyptus oil and yields up to 12.75% by weight of partly dried leaves. Some forms of E. dives contain mostly the essential oils phellandrene and piperitone, some also contain eucalyptol and the remainder eucalyptol, terpineol, geraniol and citral. [9]
In the early post-war years there was a shortage of menthol and several manufacturers were able to produce this oil from piperitone but gradually this method was displaced by production of the oil from Mentha arvensis . The form rich in cineole is still harvested in New South Wales while the seeds imported into Africa are mostly from the piperitone/phellandrene form. [10]
Eucalyptus globulus, commonly known as southern blue gum or blue gum, is a species of flowering plant in the family Myrtaceae. It is a tall, evergreen tree endemic to southeastern Australia. This Eucalyptus species has mostly smooth bark, juvenile leaves that are whitish and waxy on the lower surface, glossy green, lance-shaped adult leaves, glaucous, ribbed flower buds arranged singly or in groups of three or seven in leaf axils, white flowers and woody fruit.

It has rough, flaky or fibrous bark on part or all of the trunk, smooth greyish to yellowish bark above. The adult leaves are lance-shaped to egg-shaped, the flower buds are arranged in groups of seven and the fruit is more or less hemispherical.
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 elata, commonly known as the river peppermint or river white gum, is a species of medium to tall tree that is endemic to eastern Australia. It has rough, compacted bark on the lower trunk, smooth bark above, lance-shaped to curved adult leaves, green to yellow flower buds arranged in groups of eleven to thirty or more, white flowers and hemispherical or shortened spherical fruit.
Eucalyptus baueriana, commonly known as blue box or round-leaved box, is a tree that is endemic to south-eastern Australia. It has rough, fibrous or flaky bark on the trunk and branches, egg-shaped adult leaves, oval to diamond-shaped flower buds arranged in groups of seven, white flowers and conical fruit.
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. It has fibrous bark on the trunk and larger branches, smooth greyish to cream-coloured bark above, or smooth bark throughout. It has broadly egg-shaped to round juvenile leaves, lance-shaped, egg-shaped or almost round adult leaves, flower buds in groups of seven, white flowers and barrel-shaped to conical fruit.
Eucalyptus miniata, commonly known as the Darwin woollybutt or woolewoorrng, is a species of medium-sized to tall tree that is endemic to northern Australia. It has rough, fibrous, brownish bark on the trunk, smooth greyish bark above. Adult leaves are lance-shaped, the flower buds are ribbed and arranged in groups of seven, the flowers orange or scarlet and the fruit is cylindrical to barrel-shaped or urn-shaped, with ribs along the sides.
Eucalyptus acmenoides, commonly known as white mahogany or barayly, is a tree that is endemic to eastern Australia. It is a large tree with grey to reddish brown, stringy bark, lance-shaped leaves, oval to spindle-shaped buds and more or less hemispherical fruits. The two sides of adult leaves are very different shades of green.
Corymbia eximia, commonly known as yellow bloodwood, is a bloodwood native to New South Wales. It occurs around the Sydney Basin often in high rainfall areas on shallow sandstone soils on plateaux or escarpments, in fire prone areas. Growing as a gnarled tree to 20 m (66 ft), it is recognisable by its distinctive yellow-brown tessellated bark. The greyish green leaves are thick and veiny, and lanceolate spear- or sickle-shaped. The cream flowerheads grow in panicles in groups of seven and appear in spring. Known for many years as Eucalyptus eximia, the yellow bloodwood was transferred into the new genus Corymbia in 1995 when it was erected by Ken Hill and Lawrie Johnson. It is still seen under the earlier name in some works.

It is a large shrub or small tree with papery bark on the trunk, small, sharp leaves and small heads of fluffy flowers in spring. It should not be confused with Callistemon sieberi. When the callistemons were moved to Melaleuca, Callistemon sieberi became Melaleuca paludicola.
