Tristanieae is a tribe in the plant family Myrtaceae [1] from south-east Asia and Oceania.
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.
Eucalypt is a descriptive name for woody plants with capsule fruiting bodies belonging to seven closely related genera found across Australasia: Eucalyptus, Corymbia, Angophora, Stockwellia, Allosyncarpia, Eucalyptopsis and Arillastrum.
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.
Metrosideros is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the family Myrtaceae. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek metra or "heartwood" and sideron or "iron". Perhaps the best-known species are the pōhutukawa, northern rātā, and southern rātā of New Zealand, and ʻōhiʻa lehua,, from the Hawaiian Islands.
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.
The biodiversity of New Caledonia is of exceptional biological and paleoecological interest. It is frequently referred to as a biodiversity hotspot. The country is a large South Pacific archipelago with a total land area of more than 18,000 square kilometres (6,900 sq mi). The terrain includes a variety of reefs, atolls, small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. The region's climate is oceanic and tropical.
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.
Tristaniopsis is a group of shrub and tree in the myrtle family Myrtaceae described as a genus in 1863. They have a wide distribution in Southeast Asia, New Guinea, New Caledonia and Australia.
Archirhodomyrtus is a genus of flowering plants in the myrtle family, Myrtaceae, describe as a genus in 1941. There are five known species, four native to New Caledonia and one native to Australia.
Xanthostemon is a genus of trees and shrubs, constituting part of the myrtle plant family Myrtaceae. This genus was first described in 1857 by German–Australian botanist Ferdinand von Mueller. According to different official sources between 46 and 51 species are known to science. They grow naturally in New Caledonia, Australia, the Solomon Islands and Malesia, including the Philippines, New Guinea and Indonesia. The genera Pleurocalyptus and Purpureostemon from New Caledonia are morphologically close to Xanthostemon.
Chamelaucieae is a tribe of flowering plants within the family Myrtaceae, mostly from Australia, with a few species in New Caledonia and south-east Asia.
Boganiidae is a family of beetles, in the suborder Polyphaga. Members of the family are found in southern Africa, Australia and New Caledonia. Adults and larvae are pollenivorous, feeding on the pollen of cycads and Myrtaceae, Meliaceae, Cunoniaceae and Elaeocarpaceae angiosperms. Metacucujus and Paracucujus act as pollinators for cycads Encephalartos and Macrozamia respectively. This association with cycads goes back to at least the Mid-Cretaceous, with an extinct form being found with preserved cycad pollen in 99 million year old Burmese amber.
Lyndley Alan Craven was a botanist who became the Principal Research Scientist of the Australian National Herbarium.
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.
Pleurocalyptus is a group of shrubs and small trees in the family Myrtaceae, first described as a genus in 1868. The entire genus is endemic to New Caledonia. It is closely related to Xanthostemon.
Purpureostemon is a genus of plant in the myrtle family Myrtaceae described as a genus in 1939. There is only one known species, Purpureostemon ciliatus, endemic to New Caledonia. Purpureostemon is related to Xanthostemon.
Xanthostemoneae is a tribe in the plant family Myrtaceae. from Australia, New Caledonia, New Guinea, Solomon Islands, eastern Indonesia and the Philippines.
Eucalypteae is a large tribe of flowering plants in the family Myrtaceae; members of this tribe are known as eucalypts. In Australia the genera Angophora, Corymbia, and Eucalyptus are commonly known as gum trees, for the sticky substance that exudes from the trunk of some species. As of 2020, the tribe comprised around 860 species, all native to Southeast Asia and Oceania, with a main diversity center in Australia.
Leptospermeae is a tribe in the plant family Myrtaceae from south-east Asia and Oceania with a main diversity center in Australia.
