Melaleuca decussata, commonly known as cross-leaf honey-myrtle or totem poles, is a plant in the myrtle family, Myrtaceae native to South Australia and both native and naturalised in Victoria. It is an adaptable shrub, grown in many parts of Australia for its attractive foliage but is regarded as an environmental weed in parts of Victoria.
Melaleuca decussata is a densely branched shrub growing to a height and width of 3 m (10 ft). The leaves are arranged in alternating pairs at right angles to the ones above and below so that the leaves are in 4 rows along the stems (decussate). The leaves are 4.5–15 mm (0.2–0.6 in) long, 0.5–3 mm (0.02–0.1 in) wide, linear, narrow elliptic or narrow egg-shaped tapering to a point and concave in cross section. They also have prominent oil glands on their lower surface. [2] [3]
The flowers are a shade of pink or purple but fade rapidly to white. They are arranged in spikes on the ends of branches which continue to grow after flowering and on the sides of the branches. The spikes are up to 16 mm (0.6 in) in diameter, 20–30 mm (0.8–1 in) long and have between 6 and 22 individual flowers. The petals are 1.8–2.3 mm (0.07–0.09 in) long and fall off as the flower ages. The stamens are arranged in five bundles around the flowers with 12 to 26 stamens in each bundle. The flowering season is from August to May but flowers mostly appear from November to February in the species' native range. The fruit which follow are woody capsules, characteristically fused together at their bases and sunken in the stem. [2] [3] [4]
Melaleuca decussata was first formally described by Robert Brown in 1812 in the second edition of Hortus Kewensis from material collected from the southern coastal region of Australia. [5] [6] The specific epithet (decussata) refers to the decussate arrangement of the leaves. [2]
Melaleuca decussata occurs between coastal areas of South Australia (including the Eyre Peninsula) and the centre of eastern Victoria. [2]
This species has been declared an environmental weed in the Geelong area, the catchments of the Broken and Goulburn rivers and in the Wimmera bioregion. It is a garden escape which becomes naturalised in grasslands and grassy woodland. It is believed to be a threat to several natural vegetation associations and forms dense stands in native pastures. [7] It grows in low nutrient soils subject to inundation. [4]
Melaleuca decussata is a hardy garden plant with attractive foliage. It will grow in most situations and has attractive mauve-coloured flowers, although they fade quickly to white. [8] It is not advisable to plant this species within 6 metres (20 ft) of a wastewater pipe because of its potential to cause damage. [9]
Melaleuca armillaris, commonly known as bracelet honey myrtle, is a plant in the myrtle family, Myrtaceae, and is native to South Australia, Victoria and Tasmania in south-eastern Australia. It is a hardy, commonly grown species, often used as a fast-growing screen plant, but it also has the potential to become a weed. It has become naturalised in Western Australia and parts of Victoria. In its natural state, it grows on coastal cliffs and along estuaries.
Melaleuca fulgens, commonly known as the scarlet honey myrtle, is a plant in the myrtle family Myrtaceae, and is endemic to Western Australia, South Australia and the Northern Territory.

It is a member of Melaleuca, a large and diverse genus whose members range from large trees such as M. quinquenervia, to small shrubs.

Melaleuca thymifolia, commonly known as thyme honey-myrtle, is a plant in the myrtle family Myrtaceae and is native to eastern Australia. It is often noticed in spring, with its attractive, purple flowers and is one of the most commonly cultivated melaleucas. A fragrant shrub, it usually grows to about 1.0 m (3 ft) tall, has corky bark and slender, wiry stems.
Melaleuca wilsonii, commonly known as Wilson's honey-myrtle or violet honey-myrtle, is a plant in the myrtle family, Myrtaceae, native to parts of South Australia and Victoria. It is a shrub with narrow, pointed leaves and heads of purplish-pink flowers on the sides of the branches. It is adaptable to a wide range of soils, frost hardy and often cultivated.
Melaleuca pulchella, commonly known as claw flower and claw honey-myrtle, is a plant in the myrtle family Myrtaceae, and is endemic to the south of Western Australia. It is one of only two species of Melaleuca to have two kinds of stamens. The outer stamens are longer and curved, giving the appearance of a claw to the flower. It is a hardy shrub flowering over a long period, and has been a popular garden plant for many years.
Melaleuca hypericifolia, commonly known as hillock bush, is a plant in the myrtle family, Myrtaceae, genus Melaleuca and is endemic to New South Wales in Australia. It has large, orange to red flower spikes and consequently is a commonly cultivated species. In 1797, James Edward Smith described the plant as:
Melaleuca uncinata, commonly known as broombush, broom honeymyrtle or brushwood, is a plant in the paperbark family native to southern Australia. It is harvested from the wild, and grown in plantations, for broombush fencing. The Noongar names for the plant are kwytyat and yilbarra.
Melaleuca gibbosa, commonly known as the slender honey-myrtle or small-leaved honey-myrtle is a plant in the myrtle family, Myrtaceae and is endemic to southern Australia. It is a dense, bushy shrub to about 2 metres (6.6 ft) with numerous slender, arching branches and oblong heads of mauve flower spikes in spring and sparsely throughout the year.

It has pointed, non-prickly leaves and cylindrical spikes of pink or purple flowers.
Melaleuca diosmifolia is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It has also become naturalised in Victoria (Australia) Australia. It is unusual for its genus in that the flowers are green, which partly accounts for its popularity as a garden plant. It is only distantly related to Melaleuca diosmatifolia although its species name has a similar etymology.

Melaleuca fulgens subsp. fulgens, commonly known as the scarlet honey myrtle, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. In 1990, the species Melaleuca fulgens was separated into 3 subspecies and this is the most widespread of them.

In 1990, the species Melaleuca fulgens was separated into 3 subspecies. Of the two subspecies occurring in the south-west, this one has the narrower distribution, occurring mainly near Geraldton.

In 1990, the species Melaleuca fulgens was separated into 3 subspecies. This subspecies has a disjunct distribution but is nevertheless very similar to the other two, only differing the colour of the flowers and small differences in the leaf shape and length of the stamens. As with the other subspecies, this one is notable for its showy flowers which are usually a shade of pink to mauve but its foliage and fruits are also attractive features.
