Melaleuca viridiflora, commonly known as broad-leaved paperbark, [2] is a plant in the myrtle family Myrtaceae, and is native to woodlands, swamps and streams in monsoonal areas of northern Australia and New Guinea. It is usually a small tree with an open canopy, papery bark and spikes of cream, yellow, green or red flowers.
Melaleuca viridiflora is a shrub or small tree usually growing to 10 m (30 ft) tall, sometimes twice that height, with white, brownish or grey bark and an open canopy. Its leaves are 70–195 mm (3–8 in) long, 19–76 mm (0.7–3 in) wide, thick, broadly elliptic and aromatic. [2] [3] [4] [5]
The flowers are cream, yellow, yellow-green or occasionally red and arranged in spikes on the ends of branch which continue to grow after flowering and sometimes also in the upper leaf axils. Each spike contains 8 to 25 groups of flowers in threes and is up to 100 mm (4 in) long and 55 mm (2 in) in diameter. The petals are 4–5.3 mm (0.16–0.21 in) long and fall off as the flower matures. There are five bundles of stamens around the flower, each with 6 or 9 stamens although the stamens are only weakly joined in bundles. Flowering can occur at any time of the year but most commonly happens in winter. Flowering is followed by fruit which are woody capsules 5–6 mm (0.20–0.24 in) long, scattered along the stem, each containing numerous fine seeds. [2] [3] [4] [5]
Melaleuca viridiflora was first formally described in 1788 by Daniel Solander, the description published by Joseph Gaertner in De fructibus et seminibus plantarum [6] [7] including a carefully drawn figure of the stamen bundle and fruiting capsules. [8] The description was made during the forced stay of the Endeavour on the banks of the Endeavour River, at the site of the present-day Cooktown, during the first voyage of James Cook. [9] The specific epithet (viridiflora) means "green-flowered", referring to the most common flower colour of this species. [3]
This melaleuca occurs in tropical areas of Australia, including as far south as Maryborough in Queensland, northern parts of Western Australia south to the Dampier Peninsula district, and the northern half of the Northern Territory. It is also found in the southern part of West Papua in Indonesia and southern Papua New Guinea. It grows on the margins of gallery forest, in forest, woodland and swampy plains in a variety of soils. [2] [3]
Melaleuca viridiflora forests provide habitat for orchid species including the rare, threatened or endangered Calochilus psednus , Pachystoma pubescens , Eulophia bicallosa and Cardwell midge orchid ( Genoplesium tectum ). Individual trees often host the epiphytic ant-house plant, ( Myrmecodia beccarii ). [10]
Plants distributed in south-eastern Florida in 1900 under the name Melaleuca viridiflora have been subsequently identified as Melaleuca quinquenervia . [11]
Melaleuca viridiflora is used by Aboriginal Australians for multiple uses. The bark is peeled off in layers and is used for shelter, bedding, containers, storing and cooking food, fire tinder, watercraft, fish traps and wrapping corpses. In traditional medicine, an infusion from leaves was drunk, inhaled or used for bathing to treat coughs, colds, congestion, headache, fever and influenza. [12]
Different populations of this species yield different oils but there are two distinct groups. One is rich in terpenic oil but otherwise highly variable with three distinct chemotypes. Another population is rich in methyl cinnamate with two chemotypes. [13]
Melaleuca viridiflora is a useful and adaptable small tree in cultivation, with the red-flowered form being preferred. [14] It is suitable for tropical and subtropical areas where there is high summer rainfall, especially in heavy clay soils. Its open canopy makes it a useful host tree for epiphytes such as Dendrobium . [2] [4]
Xylomelum is a genus of six species of flowering plants, often commonly known as woody pears, in the family Proteaceae and are endemic to Australia. Plants in this genus are tall shrubs or small trees with leaves arranged in opposite pairs, relatively small flowers arranged in spike-like groups, and the fruit a woody, more or less pear-shaped follicle.
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 quinquenervia, commonly known as the broad-leaved paperbark, paper bark tea tree, punk tree or niaouli, is a small- to medium-sized tree of the myrtle family, Myrtaceae. It grows as a spreading tree up to 20 m (70 ft) tall, with its trunk covered by a white, beige and grey thick papery bark. The grey-green leaves are egg-shaped, and cream or white bottlebrush-like flowers appear from late spring to autumn. It was first formally described in 1797 by the Spanish naturalist Antonio José Cavanilles.
Melaleuca linariifolia is a plant in the myrtle family Myrtaceae, and is endemic to eastern Australia. It is commonly known as snow-in-summer, narrow-leaved paperbark, flax-leaved paperbark and in the language of the Gadigal people as budjur. A hardy plant, it flowers prolifically in late spring or summer, making it a popular garden shrub or small tree in temperate places. Melaleuca trichostachya is a similar species but its leaves are arranged differently and the fruits have projecting valves.
Melaleuca preissiana, commonly known as stout paperbark, modong or moonah, is a plant in the myrtle family, Myrtaceae and is endemic to coastal areas of southwest Australia. It is a shrub or small tree with papery bark, small leaves and spikes of usually white flowers. It occurs chiefly in areas that are seasonally wet.
Leptospermum laevigatum, commonly known as the coast tea tree, is a species of shrub or small tree that is endemic to south-eastern Australia, but has been widely introduced in other places where it is often considered to be a weed. It has thin, rough bark on the older stems, narrow egg-shaped leaves, relatively large white flowers and flat topped fruit that is shed shortly after reaching maturity.
Melaleuca leucadendra, commonly known as weeping paperbark, long-leaved paperbark or white paperbark is a plant in the myrtle family, Myrtaceae and is widespread in northern Australia, Southeast Asia, New Guinea and the Torres Strait Islands. It is a tree, sometimes growing to more than 20 m (70 ft) with a trunk covered with thick, white, papery bark and weeping thinner branches. It has a long flowering season, can flower at almost any time of the year and is often grown as a tree in parks and on roadsides. It was the first melaleuca to be described and was described from a specimen growing in Indonesia.
Corymbia gummifera, commonly known as red bloodwood, is a species of tree, rarely a mallee, that is endemic to eastern Australia. It has rough, tessellated bark on the trunk and branches, lance-shaped adult leaves, flower buds in groups of seven, creamy white flowers and urn-shaped fruit.
Melaleuca viminalis, commonly known as weeping bottlebrush or creek bottlebrush, is a plant in the myrtle family Myrtaceae, and is endemic to New South Wales, Queensland and Western Australia. It is a multi-trunked, large shrub or tree with hard bark, often pendulous foliage and large numbers of bright red bottlebrush flowers in spring and summer. It is possibly the most commonly cultivated melaleuca in gardens and its cultivars are often grown in many countries.
Melaleuca trichophylla is a shrub in the myrtle family, Myrtaceae, endemic to the south-west of Western Australia. Its pink or purple flowers appear from August to December in its native range. It has long been cultivated.
Melaleuca lanceolata commonly known as black paperbark, moonah, Rottnest Island teatree and western black tea tree is a plant in the myrtle family, Myrtaceae and is native to Australia where it occurs in Western Australia, South Australia, Victoria, New South Wales and Queensland. It is a densely foliaged tree with rough bark, which flowers prolifically in summer.
Leptospermum squarrosum, commonly known as the peach blossom tea-tree, is an upright shrub of the family Myrtaceae and is endemic to central eastern New South Wales. It has thin, firm bark, broadly lance-shaped to elliptical leaves, relatively large white or pink flowers and fruit that remain on the plant when mature.
Melaleuca squarrosa, commonly known as scented paperbark, is a plant in the myrtle family, Myrtaceae and is endemic to south eastern parts of Australia, especially Tasmania. It is an attractive shrub with dense foliage and arching branches and it flowers profusely in spring or early summer, bearing spikes of perfumed yellow to white flowers.
Melaleuca squamophloia is a plant in the myrtle family, Myrtaceae and is endemic to the black soil plains of south eastern Queensland in Australia. Like its close relative Melaleuca styphelioides, it is a small, erect tree with prickly leaves and spikes of cream or white flowers but its bark is hard rather than papery and the leaves have fewer veins than that species.
Melaleuca nodosa, commonly known as the prickly-leaved paperbark, is a plant in the myrtle family Myrtaceae, and is endemic to eastern Australia. It is a shrub or small tree with narrow, sometimes needle-like leaves and profuse heads of yellow flowers as early as April or as late as January.

Melaleuca argentea, commonly known as the silver cadjeput, silver-leaved paperbark, silver cajuput, or mardderr in the Kunwinjku language, is a plant in the myrtle family, Myrtaceae and is endemic to northern Australia. It is a common tree along river banks or around swamps in the tropics. It has papery bark and weeping foliage and has been the subject of important scientific research.
Melaleuca parvistaminea is a plant in the myrtle family, Myrtaceae, and is endemic to the states of New South Wales and Victoria in Australia. It has hard, rough bark, cream coloured flowers and leaves in whorls of three around the stems.
Melaleuca saligna is a shrub or tree in the myrtle family (Myrtaceae) and is endemic to Cape York Peninsula in Queensland. It is a small tree with papery bark on the trunk, pendulous branches and white to greenish-yellow flowers between February and November. This species should not be confused with Callistemon salignus. If that species were to be moved to the genus Melaleuca, as proposed by some authors, its name would become Melaleuca salicina. Melaleuca saligna has its stamens arranged in bundles; the stamens of Callistemon salignus/Melaleuca salicina are all free.
Leptospermum arachnoides, commonly known as the spidery tea-tree, is a species of shrub that is endemic to eastern Australia. It has rough bark, crowded linear to lance-shaped leaves with a sharp point on the end, white flowers and hairy fruit.
