Acacia Arrecta
''Acacia arrecta'', commonly known as Yarnda Nyirra wattle or Fortescue wattle, is a shrub of the genus ''Acacia'' and the subgenus ''Plurinerves'' that is endemic to arid areas in north western Australia. Description The low dense spreading shrub typically grows to a height of and to a width of about . It usually has multiple stems and can have few branches a ground level and has smooth, grey bark that can be fissured at the very base of the main stems. The branchlets have resinous ribbing. Like most species of ''Acacia'' it has 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 ...s rather than true leaves. The grey-green, resinous and terete phyllodes narrow to a hard non-spiny point. The phyllodes are in length and have a diameter of around and have eight obscure nerves ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacias Of Western Australia
''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] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, Acacia'' is not monophyletic. While the subg. ''Acacia'' and subg. ''Phyllodinae'' are monophyletic, subg. ''Aculeiferum'' is not. This subgenus consists of three clades. Therefore, the following list of ''Acacia'' species cannot be maintained as a single entity, and must either be split up, or broadened to include species previously not in the genus. This genus has been provisionally divided into 5 genus, genera, ''Acacia'', ''Vachellia'', ''Senegalia'', ''Acaciella'' and ''Mariosousa''. The proposed type species of ''Acacia'' is ''Acacia penninervis''. Which of these segregate genera is to retain the name ''Acacia'' has been controversial. The genus was previously typified with the African species ''Acacia scorpioides'' (L.) W.F.Wright, a synonym of ''Acacia nilotica'' (L.) Delile. Under the original typification, the name ''Acacia'' would stay with the group of species currently recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triodia (plant)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wittenoom, Western Australia
Wittenoom is a declared contaminated site and former townsite north-north-east of Perth, in the Hamersley Range in the Pilbara region of Western Australia. The declared contaminated site comprises , making it the "largest contaminated site in the southern hemisphere". The area around Wittenoom was mainly pastoral until the 1930s when mining for blue asbestos began in the area. By 1939, major mining began in Yampire Gorge, which was subsequently closed in 1943 when mining began in Wittenoom Gorge. In 1947 a company town was built, and during the 1950s it was the Pilbara's largest town. The peak population, as recorded by the Australian census conducted on 30 June 1961, was 881 (601 males and 280 females). During the 1950s and early 1960s Wittenoom was Australia's only supplier of blue asbestos. The mine was shut down in 1966 due to unprofitability and growing health concerns from asbestos mining in the area. The former townsite no longer receives government services. In Dece ...

Hamersley Range
The Hamersley Range is a mountainous region of the Pilbara region of Western Australia. The range was named on 12 June 1861 by explorer Francis Thomas Gregory after Edward Hamersley (senior), Edward Hamersley, a prominent promoter of his exploration expedition to the northwest. Juukan Gorge lies within the ranges, as does Karijini National Park (formerly known as Hamersley Range National Park). History The Aboriginal Australians, traditional Aboriginal owners of the area that the range runs through are the Kurrama people, Puutu Kunti Kurrama and Pinikura peoples. In 1999 a small range within the Hamersley was named the Hancock Range after the Hancock family, who were pioneers in the area. The Hancock range is east of Karijini National Park in a region of broad valleys and peaks that rise to almost . The Hancock Range is close to Mulga Downs Station, a property owned by the Hancock family and where Lang Hancock is buried. Geography The range runs from the Fortescue River in ...

Nullagine, Western Australia
Nullagine is an old goldrush town in Western Australia's Pilbara region. It is located on the Nullagine River 296 km south-east of Port Hedland and 1,364 km north-north-east of Perth on the old Great Northern Highway. The town originated from gold being discovered in the area in 1886 by a prospector, N.W. Cooke. The population increased sharply as a result and by the mid-1890s the community wanted to have a town declared. Lots were surveyed and released in 1897 and the state government gazetted the town in 1899. Nullagine comes from the Aboriginal name of a nearby river, the Ngullagine river; the meaning of the word is unknown. Besides gold other minerals were mined in the area including diamonds and other gemstones. Between 1895 and 1914 the town boomed and contained a number of general stores, three hotels, eight stamp mills and a population of over 3,000. Its population was 1,500 prior to World War II. Now, with the decline of gold mining, only about 200 remain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millstream Chichester National Park
Millstream Chichester National Park is a national park in the Pilbara region of Western Australia, located north of the state capital, Perth. The park is made up of the old Millstream Station, which is on the Millstream Creek, just before it joins Fortescue River, one of the few permanent watercourses in the area and the Chichester Range. History The area is homeland of the Yinjibarndi people. Millstream Creek was named by the explorer Francis Thomas Gregory in 1861. He reported the favourable grazing prospects. The first pastoral lease was taken up on 1865. By 1907 the property was owned by Loton and Padbury, and occupied an area of . It was stocked with 20,500 sheep, 1,900 cattle and 150 horses, and was passed in at auction at £26,000. The present Millstream Homestead was built in 1920. The homestead was a tavern between 1975 and 1986. In 1970, the Chichester Range National Park was set aside and officially named. In 1975, the Conservation through Reserves Committ ...
