Eucalypteae
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. , the tribe comprised around 860 species, all native to Southeast Asia and Oceania, with a main diversity center in Australia. Genera There are seven genera in the tribe Eucalypteae: *''Allosyncarpia'' – Australia *'' Angophora'' – Australia *''Arillastrum'' – New Caledonia *''Corymbia'' – Oceania *''Eucalyptopsis'' – Indonesia, New Guinea *''Eucalyptus'' – Southeast Asia, Oceania *''Stockwellia ''Stockwellia'' is a monotypic genus in the flowering plant family Myrtaceae.

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, 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 (i.e., without a toothed margin). 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. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciation; i ...

Angophora Hispida
''Angophora hispida'' grows as a mallee, or as a tree to about 7 m (25 ft) in height. ''A. hispidas small size, especially when compared to its '' Angophora'' and ''Eucalyptus'' relatives, leads to it being known by the common name dwarf apple. It is native to a relatively small patch of central New South Wales – from just south of Sydney up to the Gosford area. The plant's leaves are sessile (stalk-less) and hug the stem with heart-shaped bases. Its previous name – ''A. cordifolia'' – referred to these cordate leaves. Another distinctive feature are the red bristly hairs that cover the branchlets, flower bases and new growth. This leads to the specific epithet ''hispida'' (meaning "bristly"). Description The dwarf apple grows as a small tree or mallee to 7 m (25 ft) high. It has greyish flaky bark. Like other members of the genus ''Angophora'' and unlike other eucalypts, the leaves are arranged oppositely along the stem. Sitting on petiole 0–4 ...

Allosyncarpia
''Allosyncarpia ternata'', commonly known as ''an-binik'', is a species of rainforest trees constituting part of the botanical family Myrtaceae and included in the eucalypts group. The only species in its genus, it was described in 1981 by Stanley Blake of the Queensland Herbarium. They grow naturally into large, spreading, shady trees, and are endemic to the Northern Territory of Australia. They grow in sandstone gorges along creeks emerging from the Arnhem Land plateau. The common name ''anbinik'' comes from the Kundedjnjenghmi and Kundjeyhmi dialects of Bininj Kunwok, spoken in West Arnhem Land. In other dialects, such as the Kunwinjku spoken in Gunbalanya, the tree is known as ''manbinik''. Distribution and habitat The tree dominates the closed monsoon rainforest communities along the sandstone escarpment of the western Arnhem Land Plateau. The distribution of the species appears to be limited to areas not subject to wildfire. Ecology ''Allosyncarpia'' dominated rainfo ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
