Callistemon is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814. The entire genus is endemic to Australia but widely cultivated in many other regions and naturalised in scattered locations. Their status as a separate taxon is in doubt, some authorities accepting that the difference between callistemons and melaleucas is not sufficient for them to be grouped in a separate genus.
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 linearifolia, commonly known as netted bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales in Australia.. It is a shrub with narrow, pointed leaves and red flower spikes in spring or summer.
Melaleuca pachyphylla, commonly known as wallum bottlebrush, is a plant in the myrtle family Myrtaceae, and is endemic to near-coastal regions of New South Wales and Queensland in Australia.. It is a medium-sized shrub with a straggling habit and red, or sometimes greenish, bottlebrush flowers in summer.
Melaleuca pityoides, commonly known as alpine bottlebrush, is a plant in the family Myrtaceae, and is endemic to the higher areas of south eastern Australia. Some Australian state herbaria continue to use the name Callistemon pityoides. It is a shrub, often occurring in dense thickets, with hard bark, silvery-grey new growth, almost cylindrical leaves and spikes of flowers that are usually a shade of yellow.
Melaleuca williamsii is a plant in the myrtle family, Myrtaceae and is endemic to an area between north-eastern New South Wales and south eastern Queensland in Australia. It is a distinctive shrub with stiff branches, silvery new growth, prickly leaves and spikes of purple flowers in late spring. It is classified as a vulnerable species under the Australian Government Endangered Species Protection Act.
Melaleuca paludicola, commonly known as river bottlebrush, is a plant in the myrtle family Myrtaceae, and is endemic to eastern Australia. It is a shrub or small tree with flexible, often drooping branches, pinkish new growth and spikes of cream, pale yellow, or sometimes pink flowers in summer.
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 pallida, commonly known as lemon bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to eastern Australia. It is an upright shrub with thin, spreading branches, silvery new growth and pale yellow, sometimes pinkish bottlebrush flowers.
Melaleuca punicea is a plant in the myrtle family, Myrtaceae, and is endemic to the Northern Territory in Australia. Some of the characteristics of this species make it difficult to classify at the genus level. After it was originally described in 1984 as Melaleuca punicea, it was transferred in 1986 to the genus Regelia but it did not fit well in that genus either. In 1999 it was transferred again to a new genus Petraeomyrtus as P. punicea. Subsequent molecular studies, especially of chloroplast DNA have suggested that it is best placed in Melaleuca along with others from genera including Beaufortia, Callistemon and Regelia. Later publications include this species as Melaleuca punicea.
Melaleuca sieberi is a shrub or tree in the myrtle, family Myrtaceae, which is endemic to coastal areas of New South Wales and Queensland. 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.
Melaleuca flammea, commonly known as tapering-leaved bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales and Queensland in Australia. It is a shrub with broad, lance-shaped leaves which have wavy edges and taper gradually to a fine point. In spring it has typical bottlebrush flowers whose fiery colour gives the species its name.
Melaleuca flavovirens, commonly known as green bottlebrush is a plant in the myrtle family, Myrtaceae and is endemic to a small area near the New South Wales–Queensland border in Australia. It is a stiff shrub, distinguished by its silvery new growth and spikes of greenish flowers with yellow tips.
Melaleuca megalongensis, commonly known as Megalong Valley bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales.. It is a shrub similar to Melaleuca citrina which occurs in the same area and is difficult to distinguish from it, except when in flower.
Melaleuca montana, commonly known as mountain bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to the Border Ranges area of New South Wales and Queensland in Australia.. It is a shrub or small tree distinguished from most other red bottlebrushes by its hairy petals.
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.
Melaleuca shiressii is a plant in the myrtle family, Myrtaceae and is endemic to a small area in New South Wales in Australia. It is rare shrub or small tree with pale, papery bark, sharp-pointed leaves and spikes of white to pale cream bottlebrush flowers in spring and summer.
