Melaleuca is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees. They range in size from small shrubs that rarely grow to more than 16 m (52 ft) high, to trees up to 35 m (115 ft). Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers.
Myrtaceae or the myrtle family is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pohutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire. The flowers have a base number of five petals, though in several genera the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured and numerous.
Eugenia is a genus of flowering plants in the myrtle family Myrtaceae. It has a worldwide, although highly uneven, distribution in tropical and subtropical regions. The bulk of the approximately 1,100 species occur in the New World tropics, especially in the northern Andes, the Caribbean, and the Atlantic Forest of eastern Brazil. Other centers of diversity include New Caledonia and Madagascar. Many of the species that occur in the Old World have received a new classification into the genus Syzygium.
Acianthus, commonly known as mosquito orchids, is a genus of about twelve species of plants in the orchid family, Orchidaceae. Mosquito orchids are terrestrial herbs with a single, heart-shaped, usually ground-hugging leaf and one to many small, green, pinkish or purplish flowers on a fleshy stalk. They are found in New Caledonia, Australia and New Zealand.
Myoporum is a genus of flowering plants in the figwort family, Scrophulariaceae. There are 30 species in the genus, eighteen of which are endemic to Australia although others are endemic to Pacific Islands, including New Zealand, and one is endemic to two Indian Ocean islands.

Geijera is a genus of shrubs and trees in the family Rutaceae and are native to New Guinea, Australia and New Caledonia. They have simple leaves arranged alternately, panicles of bisexual flowers usually with five, sometimes four, sepals, petals and stamens and fruit containing shiny black seeds.
Uromyrtus is a genus of plants in the myrtle family Myrtaceae described as a genus in 1941. The greatest diversity of species are found in New Caledonia and the remainder are found in Australia, New Guinea and Borneo.
Austromyrtus is a genus of shrubs in the myrtle family Myrtaceae. Three species are found along the east coast of Australia; in Queensland and in New South Wales and A. lotoides being endemic to New Caledonia. The fruits of A. dulcis have a hint of cinnamon flavouring. The species under this generic name in New Caledonia are being taxonomically revised and will be transferred to another genus.
Baeckea is a genus of flowering plants in the myrtle family, Myrtaceae. There are about 75 species, of which 70 are endemic to Australia; the others are distributed in New Caledonia and Southeast Asia.
Dianella is a genus of about forty species of flowering plants in the monocot family Asphodelaceae and are commonly known as flax lilies. Plants in this genus are tufted herbs with more or less linear leaves and bisexual flowers with three sepals more or less similar to three petals and a superior ovary, the fruit a berry. They occur in Africa, South-east Asia, the Pacific Islands, New Zealand and Australia.
Dipodium, commonly known as hyacinth orchids, is a genus of about forty species of orchids native to tropical, subtropical and temperate regions of south-east Asia, New Guinea, the Pacific Islands and Australia. It includes both terrestrial and climbing species, some with leaves and some leafless, but all with large, often colourful flowers on tall flowering stems. It is the only genus of its alliance, Dipodium.
Sarcochilus, commonly known as butterfly orchids or fairy bells is a genus of about twenty species of flowering plants in the orchid family, Orchidaceae. Most species are epiphytes but a few species only grow on rocks or in leaf litter. Orchids in this genus usually have short stems, leaves arranged in two rows and flowers arranged along unbranched flowering stems. Most species are endemic to Australia but some are found in New Guinea and New Caledonia.
Gossia is a genus of rainforest trees in the myrtle family first described as a genus in 2003. It is native to northeastern Australia as well as several islands of Papuasia and New Caledonia.
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:
Lomatia myricoides, commonly known as the river lomatia, is a shrub native to New South Wales and Victoria in southeastern Australia.
Sannantha pluriflora, commonly known as tall baeckea, is a flowering shrub or small tree species in the myrtle family, Myrtaceae. It is endemic to Australia. Plants grow to 4 metres high. White flowers appear in groups of three to seven between October and April in the species' native range. These have five rounded petals surrounding 8–15 stamens. The fruits are 2.5 to 3.5 mm in diameter.
Sannantha similis is a flowering shrub or small tree species in the myrtle family, Myrtaceae. It is endemic to Australia. Plants grow to 4 metres high. White flowers appear in groups of 3 to 7 between October and January in the species' native range. These have 5 rounded petals surrounding 8 to 15 stamens. The fruits are 2.5 to 3.5 mm in diameter.
Beaupreopsis is a genus of plant in family Proteaceae, with just one species in the genus, Beaupreopsis paniculata. It is native to New Caledonia on the south of Grand Terre. Its habitat is from open maquis, to mountain area as low scrub, on a substrate of eroded ultramafic rocks.
Micromyrtus grandis, the Severn River heath-myrtle, is a shrub in the myrtle family. It is found exclusively in the Severn River Nature Preserve and a property next to it, located around 60 km north-west of Glen Innes (Australia). It grows up to 1–4 metres tall, making it the largest plant in the genus Micromyrtus. The Severn River heath-myrtle is characterized by its fruit, which is 5-ribbed, and its broader leaves when compared to other nearby flora.
