Acacia Macraneura
''Acacia macraneura'', commonly known as big mac wattle, is a shrub belonging to the genus ''Acacia'' and the subgenus ''Juliflorae'' that is native to arid parts of western Australia. Description The multi-stemmed shrub typically grows to a height of with a spreading habit but it is occasionally found as an obconic tree with a height of that has crooked stems and branches. The slightly hairy branchlets often have obscure resinous ribbing near the extremities. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The green to grey-green phyllodes have a blueish coloured tinge and are incurved or sigmoid to sinuous. The usually terete phyllodes have a length of and a diameter of with many obscure longitudinal nerves. Distribution It is endemic to the Mid West and Pilbara regions of Western Australia. It has a scattered distribution from around Mount Magnet in the south west to around Leonora in the south east to the Pilbara region and around the Rudall ...

Bruce Maslin
Bruce Roger Maslin (born 3 May 1946) is an Australian botanist, known for his work on ''Acacia'' taxonomy. Born in Bridgetown, Western Australia, he obtained an honours degree in botany from the University of Western Australia in 1967, then took up an appointment as a botanist with the Western Australian Herbarium. The following year he was conscripted to serve in the Vietnam War; he gave three years in National Service, serving in Vietnam in 1969. In 1970 he returned to his position at the Western Australian Herbarium, serving in that institution until 1987. During this time he was Australian Botanical Liaison Officer in 1977 and 1978; editor of ''Nuytsia ''Nuytsia floribunda'' is a hemiparasitic tree found in Western Australia.

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phyllode
Phyllodes are modified petioles or leaf stems, which are leaf-like in appearance and function. In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether. Thus the phyllode comes to serve the purpose of the leaf. Some important examples are ''Euphorbia royleana'' which are cylindrical and '' Opuntia'' which are flattened. They are common in the genus ''Acacia'', especially the Australian species, at one time put in ''Acacia'' subg. ''Phyllodineae''. Sometimes, especially on younger plants, partially formed phyllodes bearing reduced leaves can be seen. The illustration (to the right) of ''Acacia suaveolens'' from ''Novae Hollandiae plantarum specimen'' shows the juvenile true leaves, together with the developing phyllodes, and the phyllodes of the mature plant. The genus, ''Daviesia'', in the family Fabaceae, is characterised in part by the plants having phyllodes. File:Acacia suaveolens 9064505997 9f14f5f117 o.jpg, ''Acacia ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mount Magnet, Western Australia
Mount Magnet is a town in the Mid West region of Western Australia. It is one of the region's original gold mining towns, and the longest surviving gold mining settlement in the state. The prominent hill that is adjacent to the current townsite was called West Mount Magnet in 1854 by explorer Robert Austin, having named a smaller hill 64 km away, East Mount Magnet (now called Carron Hill). Both hills had an extremely high iron content which affected the readings of his compass. West Mount Magnet had its Aboriginal name reinstated by the Surveyor General in 1972, "Warramboo," meaning campfire camping place. The magnetic variation at Mount Magnet is zero: magnetic north equals true north. Overview Surrounding the town are remnants of old gold mining operations, and to the north east are significant Aboriginal sites being preserved jointly by the local community and the Western Australian Museum. Its history is sustained through the Wirnda Barna Arts Centre, and the Mount M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leonora, Western Australia
Leonora is a town in the Goldfields-Esperance region of Western Australia, located northeast of the state capital, Perth, and north of the city of Kalgoorlie. History The first European explorer to visit the area was John Forrest in 1869. On 21 June 1869 Forrest's party made camp near a conspicuous hill, which Forrest named Mount Leonora, after his six-year-old niece Frances (Fanny) Leonora Hardey. In 1895, gold was discovered in the area by prospector Edward "Doodah" Sullivan at the Johannesburg lease just north of the current townsite. In the following two years a number of rich finds resulted in rapid development of the area. The Sons of Gwalia gold mine brought Leonora to the attention of the world. By 1897 a residential and business area had been established, and the town was gazetted as Leonora. Leonora had a single track passenger tramway linking the town and nearby Gwalia, from 1901 to 1921. Initially steam driven, the service was electric from November 1908, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudall River
The Rudall River ( Wanman: ''Karlamilyi'') is an ephemeral river in the Pilbara region of Western Australia. The entire length of the river is located within the boundaries of the Karlamilyi National Park, which straddles the Little Sandy Desert (LSD) and the Great Sandy Desert (GSD). The headwaters of the river lie in the LSD below the Watrara Range near Island Hill, and it flows eastward into the GSD until it discharges into Lake Dora. The river is unique in the region as it is a major watercourse with reliable water sources and many permanent pools. The river has a total of nine tributaries, including Watrara Creek, Rooney Creek, Poonemerlarra Creek and Dunn Creek. The river was named by the explorer Frank Hann in 1896 after the surveyor William Frederick Rudall whom he met in the area while Hann was prospecting and Rudall was searching for men missing from the Calvert Expedition.

Little Sandy Desert
The Little Sandy Desert (LSD) is a desert region in the state of Western Australia, lying to the east of the Pilbara and north of the Gascoyne regions. It is part of the Western Desert cultural region, and was declared an interim Australian bioregion in the 1990s. History Indigenous groups that have identified with the region include the Mandilara, an Aboriginal Australian group who are regarded as the traditional owners of the land. Today the group recognised as traditional owners are the Martu people. The desert is crossed by the Canning Stock Route, an historic stock route created in the early 20th century. Description The Little Sandy Desert covers around and adjoins the Great Sandy Desert (, to the north) and the Gibson Desert (, to the east), all of which lie within the huge Australian Arid Zone which covers the centre of the Australian continent.
