Acacia Tenuispica
''Acacia tenuispica'' is a tree or shrub belonging to the genus ''Acacia'' and the subgenus ''Juliflorae'' that is endemic to north western Australia. Description The open branched spreading tree or shrub typically grows to a height of with an open;y branched, obconic habit. It has glabrous and prominently ribbed branchlets that have small rounded protuberances Band are angled towards the apices. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The thin phyllodes sometimes have small rounded projections on their surfaces and have an asymmetrical narrowly elliptic shape. The phyllodes usually have a length of and a width of and have many evenly spaced nerves with three or five often being a little more pronounced than the others. It blooms from May to July producing yellow flowers. The simple inflorescences are found in pairs in the axils with narrow and cylindrical flower-spikes that are in length and packed with golden coloured flowers. The woody r ...

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] |
Western Australian Herbarium
The Western Australian Herbarium is the State Herbarium in Perth, Western Australia. It is part of the State government's Department of Parks and Wildlife, and has responsibility for the description and documentation of the flora of Western Australia. It has the Index Herbariorum code of PERTH. The Hebarium forms part of the Australasian Virtual Herbarium.

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Walcott Inlet
Walcott Inlet is an estuary located in the Kimberley region of Western Australia. It flows into Collier Bay, in the Indian Ocean, via a narrow gap known as Yule Entrance. The inlet was named on 19 June 1865 by Trevarton Charles Sholl after Stephen Walcott, Commissioner of the Government Emigration Board, while on an exploratory expedition from the short-lived Camden Harbor settlement (in Camden Sound). The inlet is in length, with a width of and covering an area of . It is tide-dominated, but in nearly pristine condition with a catchment area of .

Prince Regent River
The Prince Regent River is a river in the Kimberley region of Western Australia. The headwaters of the river rise in the Caroline Range near Mount Agnes then flow in a north westerly direction. The river enters and flows through the Prince Regent National Park and past King Cascade and finally discharging into Saint George Basin and Hanover Bay to the Indian Ocean. The river runs a uniquely straight course following a fault line for the majority of its length. The river has six tributaries, including Quail Creek, Youwanjela Creek, Womarama Creek and Pitta Creek. The river was named in 1820 by the first European to find the river, Philip Parker King and the crew of ''Mermaid''. The river is named after the Hanoverian prince, King George IV, who was shortly to succeed his father to the throne. The first European to settle in the area was Joseph Bradshaw, who established Marigui homestead along the river with his cousin Aeneas Gunn in 1890. In 1891 he located the Gwion Gwion ...

Kimberley (Western Australia)
The Kimberley is the northernmost of the nine regions of Western Australia. It is bordered on the west by the Indian Ocean, on the north by the Timor Sea, on the south by the Great Sandy Desert, Great Sandy and Tanami Desert, Tanami deserts in the region of the Pilbara, and on the east by the Northern Territory. The region was named in 1879 by government surveyor Alexander Forrest after Secretary of State for the Colonies John Wodehouse, 1st Earl of Kimberley. History The Kimberley was one of the earliest settled parts of Australia, with the first humans landing about 65,000 years ago. They created a complex culture that developed over thousands of years. Yam (vegetable), Yam (''Dioscorea hastifolia'') agriculture was developed, and rock art suggests that this was where some of the earliest boomerangs were invented. The worship of Wandjina deities was most common in this region, and a complex theology dealing with the transmigration of souls was part of the local people's r ...

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...
