Mileura
Mileura Station is a pastoral lease located in the Mid West region of Western Australia. Description The station occupies an area of approximately and is situated approximately west of Meekatharra. The property adjoins Nookawarra Station. The station has expanses of mulga, limestone gibber, rocky outcrops, floodplains and river and creek systems. History Mileura Station was established in 1885 by Victorians Henry (Harry) Bowring Walsh (1856-1920) and his younger brother, Frederick Richard Walsh (1861-1938). With financial assistance from their father, Frederick Walsh (1831-1905) of Hawthorn, Victoria the brothers purchased about half (700,000 acres) of Nookawarra Station from the then owner, explorer Frank Wittenoom. The purchase price of ten thousand pounds included 7,000 sheep and 500 head of cattle. The brothers called their new station "Mileura" - the name of the hill from which Wittenoom had surveyed the country in 1875. A stone homestead was erected in 1890; ot ...

Plants Described In 1987
Plants are predominantly photosynthetic eukaryotes of the 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 Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and 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 color. Some plants are parasitic or mycotrophic and have lost the ability t ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Paynes Find, Western Australia
Paynes Find is a former gold rush settlement approximately northeast of Perth in the Mid West region of Western Australia. It is reachable by the Great Northern Highway. Only a roadhouse, which serves as a fuel stop, and a few other buildings remain today. The area is renowned for its wildflowers. The townsite was gazetted in 1911, the same year the gold battery was constructed. The battery is the only currently operational battery left in the state. The town is named after the prospector, Thomas Payne, who was the first to discover gold in the area and was the first to register a lease for gold mining with the Mines Department. He was rewarded with free use of the state's gold battery and his ore was the first to be crushed using the battery. The ghost town of Paynesville is also named in his honour. By the 1930s the town had prospered and the population was estimated at about 500. In 1987 the battery was sold to the Taylor family who use it as a tourist attraction. In p ...

Murchison River, Western Australia
The Murchison River is the second longest river in Western Australia. It flows for about from the southern edge of the Robinson Ranges to the Indian Ocean at Kalbarri. The Murchison-Yalgar-Hope river system is the longest river system in Western Australia. It has a mean annual flow of 208 gigalitres, although in 2006, the peak year on record since 1967, flow was 1,806gigalitres. Basin The Murchison River basin covers an area of about in the Mid West region of Western Australia. It extends about inland from the Indian Ocean, onto the Yilgarn Craton east of Meekatharra and north of Sandstone. Rain generally falls in the upper basin during summer cyclones, so for much of the year the Murchison River does not flow, leaving a dry sandy river bed and intermittent permanent pools. The eastern reaches of the basin contain large chains of salt lakes, which flow only following rainfall. The drainage lines from these lakes merge to form the Murchison River about north-northea ...

Specific Epithet
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
