Acacia Shirleyi
''Acacia shirleyi'', known colloquially as lancewood, is a species of ''Acacia'' native to Queensland and the Northern Territory in Australia. It grows as a tree to high, with dark grey or black stringy bark and blue-grey foliage. The yellow flowers appear from March to July. It grows in dry scrub, open forest or mixed Tropical and subtropical grasslands, savannas, and shrublands, savannah woodland. Indigenous people used the wood as fuel and to make hunting spears. Cattle can eat the foliage as fodder. Description The small tree has a single stem which is layered with dead bark and an umbrella shaped Habit (biology), habit. It typically grows to a height of around . The stringy bark is dark grey to black in colour, and the trunk can be up to thick. When cut or exposed, the bark will emit an odour reminiscent of viola odorata, violets. The evergreen linear to slightly curved phyllodes are around in length and wide. Veins are only found in the midrib area and are raised on b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Maiden
Joseph Henry Maiden (25 April 1859 – 16 November 1925) was a botanist who made a major contribution to knowledge of the Australian flora, especially the genus ''Eucalyptus''. This botanist is denoted by the author abbreviation when citing a botanical name. Life Joseph Maiden was born in St John's Wood in northwest London. He studied science at the University of London, but due to ill health he did not complete the course. As part of his treatment he was advised to take a long sea voyage, and so in 1880 he sailed for New South Wales. In 1881, Maiden was appointed first curator of the Technological Museum in Sydney (now the Powerhouse Museum), remaining there until 1896. While there, he published an article in 1886 describing what he called "some sixteenth century maps of Australia". These were the so-called Dieppe maps, the Rotz (1547), the Harleian or Dauphin (mid-1540s), and the Desceliers (1550), photo-lithographic reproductions of which had been published by the B ...

Acacia Distans
''Acacia distans'' is a tree belonging to the genus ''Acacia'' and the subgenus ''Juliflorae'' that is endemic to arid parts of western Australia. Description The tree typically grows to a height of and has fissured and fibrous grey bark. It has slender glabrous slender and sometimes pendulous branchlets with sericeous new shoots with hairs that become silver with age. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The thinly coriaceous grey-green phyllodes have a linear to curved shape and are in length and a width of wide and are finely striated with a central nerve that is more prominent than the others. It blooms between March and May and produces yellow flowers. The rudimentary inflorescences form two-headed racemes along an axes with cylindrical flower-spikes that have a length of up to and a diameter of packed with golden flowers. The thinly crustose seed pods that form after flowering have a linear shape but are raised over and shallowly co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CSIRO
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency that is responsible for scientific research and its commercial and industrial applications. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia as well as in France and the United States, employing over 6,500 people. Federally funded scientific research in Australia began in 1916 with the creation of the Advisory Council of Science and Industry. However, the council struggled due to insufficient funding. In 1926, research efforts were revitalised with the establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly, achieving significant early successes. In 1949, legislative changes led to the renaming of the organisation as Commonwealth Scientific and Industrial Research ...

Astringent
An astringent (sometimes called adstringent) is a chemical that shrinks or constricts body tissues. The word derives from the Latin '' adstringere'', which means "to bind fast". Astringency, the dry, puckering or numbing mouthfeel caused by the tannins in unripe fruits, lets the fruit mature by deterring eating. Tannins, being a kind of polyphenol, bind salivary proteins and make them precipitate and aggregate, producing a rough, "sandpapery", or dry sensation in the mouth. Smoking tobacco is also reported to have an astringent effect. In a scientific study, astringency was still detectable by subjects who had local anesthesia applied to their taste nerves, but not when both these and the trigeminal nerves were disabled. Uses In medicine, astringents cause constriction or contraction of mucous membranes and exposed tissues and are often used internally to reduce discharge of blood serum and mucous secretions. This can happen with a sore throat, hemorrhages, diarrhe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and Precipitation (chemistry), precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The term ''tannin'' (from scientific French ''tannin'', from French ''tan'' "crushed oak bark", ''tanner'' "to tan", cognate with English language, English ''tanning'', Medieval Latin ''tannare'', from Proto-Celtic ''*tannos'' "oak") refers to the abundance of these compounds in oak Bark (botany), bark, which was used in Tanning (leather), tanning animal Hide (skin), hides into leather. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant ...

Savannah
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da S ...

Victoria River (Northern Territory)
The Victoria River is a river in the bioregion of Victoria Bonaparte in the Northern Territory of Australia. It flows for from its source south of the Judbarra / Gregory National Park to the Joseph Bonaparte Gulf in the Timor Sea. History On 12 September 1819, Philip Parker King came to the mouth of the Victoria and, twenty years later, in 1839, Captain J. C. Wickham arrived at the same spot in and named the river after Queen Victoria. Crew members of the Beagle followed the river upstream into the interior for more than . In August 1855 Augustus Gregory sailed from Moreton Bay and at the end of September reached the estuary of the Victoria River. He sailed up the river and carried out extensive exploration. In 1847 Edmund Kennedy went on an expedition to trace the route of the "River Victoria" of Thomas Mitchell with a view to finding whether there was a practical route to the Gulf of Carpentaria. This "River Victoria" was later renamed the Barcoo River. Locati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
