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 squarrosa is a shrub, sometimes a small tree growing to 0.5–10 m (2–30 ft) high, with white or grey papery bark. Its leaves are arranged in alternating pairs (decussate) so that its leaves are in four rows along the stems. They are 5–16.2 mm (0.2–0.6 in) long, 2.5–8.2 mm (0.1–0.3 in) wide, flat and linear to narrow egg-shaped tapering to a point. They have between 5 and 7 distinct veins. [2] [3] [4] [5]
The cream-coloured flowers are arranged in spikes at the ends of branches which continue to grow after flowering. Each spike contains 4 to 20 individual flowers and is up to 22 mm (0.9 in) in diameter and 40 mm (2 in) long. The petals are 2–2.7 mm (0.08–0.1 in) long and fall off as the flower matures. There are five bundles of stamens around the flower, each with 6 to 12 stamens. Flowering mostly occurs in spring or early summer and is followed by fruit which are woody, cup-shaped to spherical capsules, 2.7–3.5 mm (0.11–0.14 in) long. [2] [3] [4]
Melaleuca squarrosa was first formally described in 1802 by James Edward Smith in Transactions of the Linnean Society of London [6] who acknowledged James Donn as follows:
"I am indebted to the Rev. Mr. Davies, F.L.S. Vice-Master of Trinity College London, for specimens of this shrub, which was raised in the Botanic Garden of the University by Mr. Donn, from seeds brought from Port Jackson, and flowered in 1799." [7]
The specific epithet (squarrosa) is a Latin word meaning "rough with stiff bracts, leaves or scales". [8]
Melaleuca squarrosa scrub is widespread throughout the west, north-east and far north-west of Tasmania especially in swampy areas. [9] On the mainland it occurs between areas near Sydney, south through Victoria to the far south-east of South Australia, growing in heath and dry sclerophyll forest in damp places in coastal districtsand the adjacent ranges. [2] [4]
This melaleuca is a useful plant as a screen plant because of its neat, dense foliage and attractive, sweetly scented flowers. [10]
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 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 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 comboynensis, commonly known as cliff bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales and Queensland in Australia. It is usually a shrub, similar to Melaleuca citrina with its hard leaves, spikes of red flowers and clusters of cup-shaped fruits but differs in that its leaves are generally wider and its habitat is usually rocky outcrops rather than along watercourses.
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.
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 notable for its showy orange, red or purple flowers, unusual foliage and fruit, and is a popular garden plant. 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 ericifolia, commonly known as swamp paperbark, is a plant in the myrtle family, Myrtaceae and the genus Melaleuca, native to south-eastern Australia. It is a rather variable species and some specimens resemble Melaleuca armillaris but its papery bark and smaller, more prolific flower heads distinguish it from that species. It often grows in swampy areas and the draining and clearing of these has reduced the numbers of the species, especially around Port Philip Bay near Melbourne. It is also similar to Melaleuca pustulata, a Tasmanian endemic, but that species only grows in dry heath.
Melaleuca subulata is a plant in the myrtle family Myrtaceae, and is endemic to south eastern Australia.. It is a small, spreading shrub with hard bark, dense foliage, cylindrical leaves and spikes of dark crimson flowers in summer.
Melaleuca brachyandra, commonly known as prickly bottlebrush or scarlet bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales, Victoria and South Australia in Australia. It is a shrub or small tree with narrow leaves and showy red and green flowers making it an ideal ornamental plant in temperate areas.
Melaleuca sapientes is a plant in the myrtle family, Myrtaceae, endemic to the south-west of Western Australia. It is a small shrub with silky grey leaves and small heads of pinkish flowers in spring or early summer. The attractive, silvery foliage has made this melaleuca a popular garden plant under the incorrect name of Melaleuca holosericea, a similar but much rarer species.
Melaleuca squamea, commonly known as swamp honey-myrtle, is a plant in the myrtle family, Myrtaceae and is endemic to south eastern parts of Australia, especially Tasmania. It is an erect shrub growing in damp and swampy places with crowded leaves and many heads of pink to purple flowers in spring.
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 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 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 pustulata, commonly known as yellow paperbark, warty paperbark or Cranbrook paperbark is a plant in the myrtle family, Myrtaceae and is endemic to Tasmania in Australia. It is an uncommon shrub, one of only two melaleucas that are endemic to that state and one of only eight found naturally occurring there. It has thick, pimply leaves, hairy new growth and large numbers of heads of pale yellow, fragrant flowers in spring or early summer.
Melaleuca calothamnoides is a plant in the myrtle family, Myrtaceae and is endemic to a relatively small area on the west coast of Western Australia. It has attractive red and green flowering spikes and soft foliage but has proven to be difficult to grow in gardens.
Melaleuca deanei, commonly known as Deane's paperbark, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales in Australia. It is a shrub with flaky bark, narrow oval leaves and spikes of white flowers in spring and summer. The species only exists in a few isolated populations and is classified as vulnerable.
Melaleuca irbyana, commonly known as weeping paperbark, bushhouse paperbark and swamp paperbark, is a plant in the myrtle family Myrtaceae and is endemic to New South Wales and Queensland in Australia. It is a shrub or small tree, often growing in pure stands in poorly drained areas. Its distribution is limited and it has been classified as an endangered species under legislation in both states and the forest as critically endangered under Australian government legislation.
Melaleuca chisholmii commonly known as Burra bottlebrush is a plant in the myrtle family, Myrtaceae and is endemic to Queensland. It is a shrub with rough bark, an open habit and spiky foliage but in winter has bright red flower spikes tipped with yellow.
Melaleuca salicina, commonly known as willow bottlebrush, is a plant in the myrtle family Myrtaceae, and is endemic to eastern Australia. Some Australian state herbaria continue to use the name Callistemon salignus, a name that is accepted by the Australian Plant Census. It is a shrub or small tree with soft foliage, pink new growth, white papery bark and spikes of usually white or creamy bottlebrush flowers in spring.
