Nitmiluk National Park
Nitmiluk National Park is in the Northern Territory of Australia, 244 km southeast of Darwin, and 23 km northeast of the town of Katherine, around a series of gorges on the Katherine River and Edith Falls. Previously named Katherine Gorge National Park, its northern edge borders Kakadu National Park. The gorges and the surrounding landscape have great ceremonial significance to the local Jawoyn people, who are custodians of Nitmiluk National Park. In the Jawoyn language, ''Nitmiluk'' means "place of the cicada dreaming". Nitmiluk (Katherine) Gorge Nitmiluk Gorge, a deep gorge carved through ancient sandstone by the Katherine River, is the central attraction of the park. Nitmiluk Gorge is made up of thirteen gorges, with rapids and falls, and follow the Katherine River, which begins in Kakadu. During the Dry, roughly from April to October, the Nitmiluk Gorge waters are placid in most spots and ideal for swimming and canoeing. There may be freshwater crocodiles in m ...

Top End
The Top End of Australia's Northern Territory is a geographical region encompassing the northernmost section of the Northern Territory, which aside from the Cape York Peninsula is the northernmost part of the Australian continent. It covers a rather vaguely defined area of about 245,000 km² (95,000 sq mi) behind the northern coast from the Northern Territory capital of Darwin across to Arnhem Land with the Indian Ocean on the west, the Arafura Sea to the north, and the Gulf of Carpentaria to the east, and with the almost waterless semi-arid interior of Australia to the south, beyond the huge Kakadu National Park. The Top End contains both of the Territory's cities and one of its major towns, Darwin, Palmerston and Katherine. The well-known town of Alice Springs is located further south, in the arid southern part of the Northern Territory, sometimes referred to by Australians as the Red Centre. The landscape is relatively flat with river floodplains and grasslands with eucaly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Flora Of Australia
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proteales Of Australia
Proteales is an order of flowering plants consisting of three (or four) families. The Proteales have been recognized by almost all taxonomists. The representatives of the Proteales are very different from each other. The order contains plants that do not look alike at all. What they have in common is seeds with little or no endosperm. The ovules are often atropic. Families In the classification system of Dahlgren the Proteales were in the superorder Proteiflorae (also called Proteanae). The APG II system of 2003 also recognizes this order, and places it in the clade eudicots with this circumscription: * order Proteales :* family Nelumbonaceae :* family Proteaceae family Platanaceae">Platanaceae.html" ;"title=" family Platanaceae"> family Platanaceae with "+ ..." = optionally separate family (that may be split off from the preceding family). The APG III system of 2009 followed this same approach, but favored the narrower circumscription of the three families, firmly reco ...

Grevillea
''Grevillea'', commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus ''Grevillea'' are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds. Description Plants in the genus ''Grevillea'' are shrubs, rarely small trees with simple or compound leaves arranged alternately along the branchlets. The flowers are zygomorphic and typically arranged in pairs along a sometimes branched raceme at the ends of branchlets. The flowers are bisexual, usually with four tepals in a single whorl. There are four stamens and the gynoecium has a single carpel. The fruit is a thin-walled follicle that splits down only one side, releasing one or two seeds before the next growing season. Taxonomy The genus ''Grevillea'' was first forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roper River
The Roper River is a large perennial river located in the Katherine region of the Northern Territory of Australia. Location and features Formed by the confluence of the Waterhouse River and Roper Creek, the Roper River rises east of Mataranka in the Elsey National Park and flows generally east for over to meet the sea in Limmen Bight on the Gulf of Carpentaria. The river is joined by fifteen tributaries including the Chambers, Strangways, Jalboi, Hodgson and the Wilton Rivers. The river descends over its course and has a catchment area of , which is one of the largest river catchment areas in the Northern Territory. The Roper River is navigable for about , until the tidal limit at Roper Bar, and forms the southern boundary of the region known as Arnhem Land. Mataranka Hot Springs and the township of Mataranka lie close to the river at its western end. Port Roper lies near its mouth on Limmen Bight. The river has a mean annual outflow of .

Gove Peninsula
The Gove Peninsula is at the northeastern corner of Arnhem Land in the Northern Territory of Australia. The peninsula became strategically important during World War II when a Royal Australian Air Force base was constructed at what is now Gove Airport. The peninsula was involved in a famous court case known as the Gove land rights case, when local Yolngu people tried to claim native title over their traditional lands in 1971, after the Australian Government had granted a mineral lease to a bauxite mining company without consulting the local peoples. Today the land is owned by the Yolngu people. Location The Gove Peninsula is on the west coast of the Gulf of Carpentaria within Arnhem Land, a vast tract of Aboriginal-owned land on the Northern Territory coastline. The township of Nhulunbuy is the main commercial and service centre of the Peninsula and is 600 kilometres east of Darwin.

It has a range of services, including a police station, school and community arts centre, Injalak Arts. It is the nearest town to the Awunbarna, also known as Mount Borradaile, an Aboriginal sacred site and the location of significant Indigenous Australian rock art. Etymology and history The area now known as Gunbalanya was originally called "Uwunbarlany" by Erre-speaking people, who were its original inhabitants. Oenpelli was the way Paddy Cahill (1863–1923), the founder of the original cattle station in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...
