Acacia Subcontorta
''Acacia subcontorta'' is a shrub belonging to the genus ''Acacia'' and the subgenus ''Juliflorae'' that is endemic to central and central western Australia. Description The shrub or trees usually has multiple stems and typically grows to a height of with a rounded and spreading crown that is across and becomes sparser with age. The trunks appear contorted and have a diameter of around at breast height and with the contorted looking main branches spreading more or less horizontally. The thin grey coloured bark has a fibrous texture and is longitudinally fissured along the main branches and trunks. The terete and glabrous branchlets have obscure ribbing and are a light brown colour at the extremities. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The evergreen, moderately coriaceous to sub-rigid phyllodes have a linear to narrowly elliptic shape with a length of and a width of with many fine parallel longitudinal nerves.

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.

Gibson Desert
The Gibson Desert is a large desert in Western Australia, largely in an almost "pristine" state. It is about in size, making it the fifth largest desert in Australia, after the Great Victoria, Great Sandy, Tanami and Simpson deserts. The Gibson Desert is both an interim Australian bioregion and desert ecoregion. Location and description The Gibson Desert is located between the saline Kumpupintil Lake and Lake Macdonald along the Tropic of Capricorn, south of the Great Sandy Desert, east of the Little Sandy Desert, and north of the Great Victoria Desert. The altitude rises to just above in places. As noted by early Australian explorers such as Ernest Giles large portions of the desert are characterized by gravel-covered terrains covered in thin desert grasses and it also contains extensive areas of undulating red sand plains and dunefields, low rocky/gravelly ridges and substantial upland portions with a high degree of laterite formation. The sandy soil of the later ... [...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] |
Ironstone
Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially. Not to be confused with native or telluric iron, which is very rare and found in metallic form, the term ''ironstone'' is customarily restricted to hard, coarsely banded, non-banded, and non-cherty sedimentary rocks of post-Precambrian age. The Precambrian deposits, which have a different origin, are generally known as banded iron formations. The iron minerals comprising ironstones can consist either of oxides, i.e. limonite, hematite, and magnetite; carbonates, i.e. siderite; silicates, i.e. chamosite; or some combination of these minerals.U.S. Bureau of Mines Staff (1996) ''Dictionary of Mining, Mineral, & Related Terms.''

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 ...

Ethel Creek Station
Ethel Creek Station is a pastoral lease that operates as a cattle station. It is located about north east of Newman and south of Nullagine in the Pilbara region of Western Australia. It had about double frontage to the Fortescue River and adjoins Roy Hill, Balfour Downs, Three Rivers, Muura Munda and Sylvania Stations. The country is mostly alluvial flats that support a variety of grasses. The station was established in about 1880 by Charles Smith. A new stock route passed through the area in 1895. Jack Bates, the drover husband of Daisy Bates, acquired Ethel Creek at some time before 1902. The Bates family, including the 15-year-old Arnold Bates, bought cattle at Roebuck Plains, near Broome and overlanded the 770 head of Hereford cattle for over back to Ethel Creek. The journey took about six months and although they lost 200 head along the way they still made a profit of over !,000. The Bates' were legally separated in 1912. Messrs J and L Smith acquired the prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
