York Gum
''Eucalyptus loxophleba'', commonly known as York gum, daarwet, goatta, twotta or yandee, is a species of tree or mallee that is endemic to Western Australia. It has rough bark on the trunk, smooth olive to brownish bark above, lance-shaped adult leaves, flowers buds in groups of between seven and eleven, white flowers and conical fruit. Description ''Eucalyptus loxophleba'' is a mallee or a tree that typically grows to a height of and forms a lignotuber. The trunk has a diameter of about of and varying amounts, depending on subspecies, of rough fibrous-flaky or smooth bark on the trunk and smooth grey-brown over copper bark above. Young plants and coppice regrowth have more or less triangular, egg-shaped or almost round glaucous leaves that are long and wide. Adult leaves are lance-shaped to curved, the same glossy, dark green on both sides, long and wide tapering to a petiole long. The flower buds are arranged in leaf axils in groups of seven, nine or eleven on an unbra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

Wheatbelt (Western Australia)
The Wheatbelt is one of nine regions of Western Australia defined as administrative areas for the state's regional development, and a vernacular term for the area converted to agriculture during colonisation. It partially surrounds the Perth metropolitan area, extending north from Perth to the Mid West region, and east to the Goldfields–Esperance region. It is bordered to the south by the South West and Great Southern regions, and to the west by the Indian Ocean, the Perth metropolitan area, and the Peel region. Altogether, it has an area of (including islands). The region has 42 local government authorities, with an estimated population of 75,000 residents. The Wheatbelt accounts for approximately three per cent of Western Australia's population. Ecosystems The area, once a diverse ecosystem, reduced when clearing began in the 1890s with the removal of plant species such as eucalypt woodlands and mallee, is now home to around 11% of Australia's critically end ...

Mid West (Western Australia)
The Mid West region is one of the nine regions of Western Australia. It is a sparsely populated region extending from the west coast of Western Australia, about north and south of its administrative centre of Geraldton, Western Australia, Geraldton and inland to east of Wiluna, Western Australia, Wiluna in the Gibson Desert. It has a total area of , and a permanent population of about 52,000 people, more than half of those in Geraldton. Earlier names The western portion of this region was known earlier as "The Murchison" based on the Murchison River (Western Australia), river of the same name, and the similarly named Goldfield. Economy The Mid West region has a diversified economy that varies with the geography and climate. Near the coast, annual rainfall of between allows intensive agriculture. Further inland, annual rainfall decreases to less than , and here the economy is dominated by mining of iron ore, gold, nickel and other mineral resources. Geraldton is an imp ...

Autonym (botany)
In botanical nomenclature, autonyms are automatically created names, as regulated by the ''International Code of Nomenclature for algae, fungi, and plants'' that are created for certain subdivisions of genera and species, those that include the type of the genus or species. An autonym might not be mentioned in the publication that creates it as a side-effect. Autonyms "repeat unaltered" the genus name or species epithet of the taxon being subdivided, and no other name for that same subdivision is validly published (article 22.2). For example, ''Rubus'' subgenus ''Eubatus'' is not validly published, and the subgenus is known as ''Rubus'' subgen. ''Rubus''. Autonyms are cited without an author. The publication date of the autonym is taken to be the same as that of the subdivision(s) that automatically established the autonym, with some special provisions (the autonym is considered to have priority over the other names of the same rank established at the same time (article 11.6)).

Lawrence Alexander Sidney Johnson
Lawrence Alexander Sidney Johnson FAA, (26 June 1925 – 1 August 1997) known as Lawrie Johnson, was an Australian taxonomic botanist. He worked at the Royal Botanic Gardens, Sydney, for the whole of his professional career, as a botanist (1948–1972), Director (1972–1985) and Honorary Research Associate (1986–1997). - originally published in ''Historical Records of Australian Science'', vol.13, no.4, 2001. Alone or in collaboration with colleagues, he distinguished and described four new families of vascular plants, 33 new genera, 286 new species (including posthumous publications), and reclassified another 395 species. Of the families he described, Rhynchocalycaceae (with B. G. Briggs, 1985) is accepted by the Angiosperm Phylogeny Group (APG). Hopkinsiaceae and Lyginiaceae, (which he and B. G. Briggs proposed in 2000 be carved out of Anarthriaceae), have not been accepted by the APG. Lawrie Johnson died of cancer in 1997. He received many honours and awards, including ...
