Backhousia Tetraptera
''Backhousia tetraptera'' is a tree in the family Myrtaceae. The only known population occurs at the foot of Mount Stuart Mount Stuart is a mountain in the Cascade Range, in the U.S. state of Washington. It is the second highest non-volcanic peak in the state, after Bonanza Peak and seventh-highest overall. Mount Stuart is the highest peak in the Stuart Range, and ... near Townsville in Queensland, Australia. The species grows to between 5 and 12 metres high often with multiple trunks that have a mottled flaking bark including grey, grey-brown and/or pink colouration. The leaves are simple and opposite and are 5.5 to 9 cm long and 1.5 to 3.8 cm wide. The white flowers appear in clusters of 10 and have 56 to 65 stamens. Flowering is induced by the first significant rainfall of the wet season, appearing four weeks later. The distinctive fruits are capsules with four wings that appear in clusters and fade from pink to white and dry to brown. The species was formally ...

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 ...

Mount Stuart, Queensland
Mount Stuart is a locality in the City of Townsville, Queensland, Australia. In the , Mount Stuart had no population. Geography The Ross River forms the western boundary of the locality. The Ross River Dam is at the south-west of the locality which forms Lake Ross which is the south-western boundary of the locality. The terrain is mountainous rising to the peak of Mount Stuart (584 metres) (). There is a lookout at the top of the mountain with views over the Townsville area. It is accessed via the Mount Stuart Road which commences at Stuart Drive in neighbouring Roseneath. As at November 2018, the locality is otherwise undeveloped. History The mountain and hence the locality were named after Clarendon Stuart, a surveyor who undertook the first survey of the Town of Bowen in 1861. He also surveyed the first allotments in Townsville in 1865. In 1868 he worked in Gympie as the Gold Commissioner. Then he moved to New South Wales working in the office of the New South Wales S ...

Townsville
Townsville is a city on the north-eastern coast of Queensland, Australia. With a population of 180,820 as of June 2018, it is the largest settlement in North Queensland; it is unofficially considered its capital. Estimated resident population, 30 June 2018. Townsville hosts a significant number of governmental, community and major business administrative offices for the northern half of the state. Part of the larger local government area of the City of Townsville, it is in the dry tropics region of Queensland, adjacent to the central section of the Great Barrier Reef. The city is also a major industrial centre, home to one of the world's largest zinc refineries, a nickel refinery and many other similar activities. As of December 2020, $30M operations to expand the Port of Townsville are underway, which involve channel widening and installation of a 70-tonne Liebherr Super Post Panamax Ship-to-Shore crane, to allow much larger cargo and passenger ships to utilise the port.

Backhousia
''Backhousia'' is a genus of thirteen currently known species of flowering plants in the family Myrtaceae. All the currently known species are endemic to Australia in the rainforests and seasonally dry forests of Queensland, New South Wales and Western Australia. In 1845 in the European science publication the ''Botanical Magazine'' William Jackson Hooker and William Henry Harvey first published this genus's formal description and name, after botanist James Backhouse from England and Australia. They grow to aromatic shrubs or trees from tall, with leaves long and wide, arranged opposite to each other. Species Sourced from the authoritative ''Australian Plant Name Index'' and ''Australian Plant Census'' . For taxa including undescribed species further afield outside Australia, for example likely in New Guinea, this list lacks them—refer also to the genus ''Kania''. * ''Backhousia angustifolia'' , curry myrtle, narrow leaf myrtle * ''Backhousia bancroftii'' , Johnstone Rive ...

Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae ('' Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the ...

Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill. (including Oliniaceae Arn., Rhynchocalycaceae L. A. S. Johnson & B. G. Briggs) * Vochysiaceae A. St.-Hil. The Cronquist system gives essentially the same co ...

Flora Of Queensland
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 2012
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Betsy Rivers Jackes
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
