Mary River (Northern Territory)
The Mary River flows in the Northern Territory of Australia and is a site of the Mary River National Park. Description The river is approximately long and rises about east of Pine Creek. The catchment area is over but is ephemeral and only flows in the wet season, during the dry it is a series of pools and billabongs. The catchment has several small reserve areas forming the Mary River National Park to help protect it. The Arnhem Highway crosses the river near one of the park areas. It also supports multiple land uses including pastoralism, fishing, mining, defence force, tourism, conservation and horticulture. Pastoralism, particularly cattle grazing is the dominant use taking up 63% of the catchment area. The river has a total of ten tributaries including the Little Mary River, MacKinlay River, Bowerbird Creek, Mingloo Creek and Douglas Creek. It has a mean annual outflow of , Its lower reaches form part of the Adelaide and Mary River Floodplains Important Bird Area. T ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Goodenia
''Goodenia'' is a genus of about two hundred species of flowering plants in the family Goodeniaceae. Plants in this genus are herbs or shrubs, mostly endemic to Australia. The leaves are variably-shaped, the flowers arranged in small groups, with three or five sepals, the corolla bilaterally symmetrical and either fan-shaped with two "lips" or tube-shaped. The petals are usually yellow to white, the stamens free from each other and the fruit a capsule. Taxonomy The genus ''Goodenia'' was first formally described in 1793 by James Edward Smith in his book ''A Specimen of the Botany of New Holland'' and the first species he described was '' G. ramosissima''. The name ''Goodenia'' honours Bishop of Carlisle Samuel Goodenough, a member of the Linnean Society of London at the time. Species list See List of ''Goodenia'' species Distribution Most species of ''Goodenia'' are endemic to Australia but '' G. konigsbergeri'' is endemic to Southeast Asia.

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] |
Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telopea (journal)
''Telopea'' is a fully open-access, online, peer-reviewed scientific journal that rapidly publishes original research on plant systematics, with broad content that covers Australia and the Asia-Pacific region. The journal was established in 1975 and is published by the National Herbarium of New South Wales, Royal Botanic Gardens & Domain Trust. As from Volume 9, part 1, 2000, full text of papers is available electronically in pdf format.

Port Darwin
Port Darwin is the port in Darwin, Northern Territory, in northern Australia. The port has operated in a number of locations, including Stokes Hill Wharf, Cullen Bay and East Arm Wharf. In 2015, a 99-year lease was granted to the Chinese-owned Landbridge Group, a transaction that has since ignited significant national security concerns. Locations Stokes Hill Wharf operated as the main location of Port Darwin, and has had three wharves. East Arm Wharf, opened in 2000. Panamax sized ships of a maximum length of 274 metres and a DWT of up to 80,000 tonnes are able to use the location. Privatisation Following the 2012 election of the Country Liberal party, the Territory sought to raise funds for unspecified purposes through the sale of public assets, including the Territory Insurance Office and Darwin Port. In order to accomplish the latter, the Territory made a request for expressions of interest in late 2014 and early 2015, resulting in thirty-three companies signalling their ...

Maurice William Holtze
Maurice William Holtze (8 July 1840 – 12 October 1923) born in Hanover, Germany, was a botanist who established Darwin's Botanical Gardens in Fannie Bay, Darwin in 1878. When he left to take charge of Adelaide's Botanic Garden in 1891, his son Nicholas was appointed curator of the Darwin Botanical Gardens in his place.Kraehenbuehl, D. K"Holtze, Maurice William (1840–1923)"''Australian Dictionary of Biography Online'', accessed 20 March 2011 Holtze studied at Hildesheim and Osnabrück before serving an apprenticeship in Hanover, where he subsequently worked for four years in the Royal Gardens. He spent two years in the Imperial Gardens of St. Petersburg before emigrating in 1872 to Melbourne, then to Darwin, Northern Territory. While in Darwin (then called Palmerston, later Port Darwin) he made trial plantings of a large number of tropical plants of potential economic importance: rubber, rice, peanuts, tobacco, sugar, coffee, indigo and maize. He supplied the sugarcane tube ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nut (fruit)
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, a wide variety of dry seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent). Most seeds come from fruits that naturally free themselves from the shell, but this is not the case in nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. The general and original usage of the term is less restrictive, and many nuts (in the culinary sense), such as almonds, pecans, pistachios, walnuts, and Brazil nuts, are not nuts in a botanical sense. Common usage of the term often refers to any hard-walled, edible kernel as a nut. Nuts are an energy-dense and nutrient-rich food source. Botanical definition A seed is the mature fertilised ovule of a plant; it consists of three parts, the embryo which will develop into a ne ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...
