Melaleuca atroviridis is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It was formerly included in the species Melaleuca uncinata but a review of that species lead to the identification of a number of new species. Like M. uncinata, this species is used for the production of brushwood fencing. It has fewer stamens in the flowers and somewhat smaller clusters of fruit but has the same needle-like leaves with a hooked end and spikes of creamy yellow flowers in early summer.
Melaleuca atroviridis is a large shrub sometimes growing to a height of 12 m (40 ft) and has dark, flaking papery bark. Its leaves mostly point upwards, are almost circular in cross-section, 22–56 mm (0.9–2 in) long and 0.6–1.4 mm (0.02–0.06 in) wide. The ends of the leaves taper to a hook. [1]
The flowers are a cream or yellow and arranged in spikes containing 5 to 27 groups of flowers in threes. The spikes are 15–17 mm (0.6–0.7 in) in diameter. The petals are 1.3–1.6 mm (0.05–0.06 in) long and fall off as the flower opens. The stamens are arranged in five bundles of around the flower, with 7 to 11 stamens in each bundle. The flowering season lasts from December to February and is followed by fruit which are woody capsules. The fruits become so closely packed together that they lose their individual identities and form a cylinder 5.4–8.5 mm (0.2–0.3 in) in diameter. [1] [2]
Melaleuca atroviridis was first formally described in 2004 by Lyndley Craven and Brendan Lepschi in Australian Systematic Botany from a specimen collected near Goomalling. [3] [4] The specific epithet (atroviridis) is from the Latin ater meaning "black" and viridis meaning "green", referring to the dark green colour of the foliage of this species. [1]
This melaleuca occurs in and between the Coorow, Perenjori, Wubin, Yellowdine, Beaufort River, Pingrup and Varley districts [1] in the Avon Wheatbelt, Coolgardie, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, Murchison and Yalgoo bieogeographic regions. It grows in woodland, shrubland and samphire on a range of soils and on saline sites, including those on degraded land. [5]
This species is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [5]
Melaleuca atroviridis is one of the species used in the production of brushwood fencing and is sometimes cultivated for that purpose. [1] Tests have shown that it grows well in sand that is saline but not so well on salt affected loam or clay. [6] [7]
Melaleuca penicula is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is a rare species only known from the Fitzgerald River National Park and resembles Melaleuca eximia with its spikes of red flowers but its leaves and stamen bundles are different.
Melaleuca amydra is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to Melaleuca ryeae with its small, compact form, oval leaves and "pom-pom" heads of pink to purple flower heads on the ends of the branches in spring.
Melaleuca barlowii is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to a number of other Western Australian melaleucas such as M. conothamnoides with its purple pom-pom flower heads but is a more erect shrub with different leaves and the fruiting clusters have a different shape.
Melaleuca caeca is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to a number of other Western Australian melaleucas such as M. pentagona with its purple pom-pom flower heads but it is a smaller shrub with narrower leaves and smaller inflorescences.
Melaleuca campanae is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small, woody shrub similar to Melaleuca eulobata, with a low, spreading habit and pinkish flower heads but it has longer, pointed leaves and lacks distinct sepals which instead form a ring of tissue around the edge of the flowers.
Melaleuca carrii is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small shrub similar to Melaleuca pentagona, with "pom-pom" heads of pinkish flowers and sharply pointed leaves but it is generally smaller, lacks a groove in its leaves and retains its petals on the flowers for longer than that species.
Melaleuca clavifolia is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small shrub similar to Melaleuca tinkeri, with "pom-pom" heads of pinkish flowers and soft, silky hairs on the new growth but it has larger flower heads and its leaves are shorter, more club-shaped and have less distinct oil glands.
Melaleuca exuvia is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is easily distinguished by its unusual rough, minni ritchi bark which peels to reveal a new layer of smooth, salmon-pink bark. It is a newly described (2004) species which was formerly included in Melaleuca uncinata.
Melaleuca interioris is a plant in the myrtle family, Myrtaceae and is endemic to Western Australia, South Australia, Queensland, New South Wales and the Northern Territory. It was formerly included in Melaleuca uncinata and is similar to that species with its cylinder-shaped leaves and small heads of yellow flowers, but with smaller, less compressed fruiting capsules.
Melaleuca linguiformis is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is a shrub with hairy new growth, small leaves and heads of white flowers similar to Melaleuca teuthidoides shorter sepals and more stamens in each flower.
Melaleuca osullivanii is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It was first formally described in 2004 after a review of the broombush group, Melaleuca uncinata. It differs from others in the group by having leaves that are fine and circular in cross section. The closest other broombrush is Melaleuca hamata whose leaves are 0.8–1.6 mm (0.03–0.06 in) in diameter compared to 0.7–0.9 mm (0.03–0.04 in) for this species.
Melaleuca scalena is a plant in the myrtle family, Myrtaceae and is endemic to the south west of Western Australia. Plants of this species were previously included in Melaleuca uncinata or broombush until a review of that species in 2004. Its leaves are narrow cylinders, the flowers in small yellow heads and the fruits tightly packed together in oval clusters. This species is very similar to Melaleuca hamata but the plants have a comparatively scruffy or less strong and healthy appearance.
Melaleuca stereophloia is a plant in the myrtle family, Myrtaceae and is endemic to the south west of Western Australia. It is similar to the broombush, Melaleuca uncinata with its needle-like leaves and heads of yellow to white flowers, but its back is hard and fibrous rather than papery.
Melaleuca vinnula is a plant in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with narrow leaves, heads of white to yellow flowers followed by tight clusters of fruit and it is found in the wheatbelt. It is a newly-described species from a review of the group of melaleucas known as broombrush.
Melaleuca zeteticorum is a shrub in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with narrow leaves and pale to bright yellow flowers in spring. Its species name zeteticorum was given "in honour of these persons who for their enjoyment explore natural vegetation communities to become familiar with their constituent species".
Melaleuca acacioides, commonly known as coastal paperbark and as lunyamad by the Bardi people, is a plant in the myrtle family, Myrtaceae and is native to the northern parts of the Northern Territory, Cape York Peninsula and New Guinea. It is closely related to Melaleuca alsophila and Melaleuca citrolens, being differentiated from them by the number of flowers in a group. In this species, they are in groups of three. It is a small to medium-sized tree, sometimes with several trunks when growing in the open. It usually grows in areas with saline soils that are regularly flooded, often near mangroves.
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 dichroma is a shrub in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is unusual for its genus in that its flowers are yellow or creamy-white but age to a pinkish-red.
Melaleuca ochroma is a plant in the myrtle family, Myrtaceae, and is endemic to the south-west of Western Australia. It is very similar to Melaleuca subfalcata, varying mainly in the length of its stamens and styles. Like M. subfalcata, it has pink to mauve flowers and leaves that are very hairy when young but become glabrous when mature.
Melaleuca protrusa is a shrub in the myrtle family, Myrtaceae, and is endemic to the south-west of Western Australia. It is a shrub with papery bark, narrow leaves with a hooked end and cream-coloured or yellow flowers. Although it was described as late as 2010, it is not considered a rare or endangered species. It resembles other members of the brushwood group such as M. uncinata, M. atroviridis and M. zeteticorum.
