Acacia Congesta
''Acacia congesta'' is a shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae'' endemic to Western Australia. Description The spreading shrub typically grows to a height of . It has dark grey bark on the trunk and larger branches. The glabrous or hairy branchlets have spinose stipules and a grey to white coloured epidermis that becomes fissured as it gets older. The pungent, dark green phyllodes are variable with a length of and a width of and have a prominent midrib and obscure to pronounces lateral nerves. It blooms from August to September and produces yellow flowers. Taxonomy The species was first formally described by the botanist George Bentham in 1842 as part of William Jackson Hooker's work ''Notes on Mimoseae, with a synopsis of species'' as published in the ''London Journal of Botany''. It was reclassified as ''Racosperma congestum'' in 2003 by Leslie Pedley then transferred back to the genus ''Acacia'' in 2006. The only other synonym is ''Acac ...

Benth
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800.Jean-Jacques Amigo, « Bentham (George) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p.

Mid West (Western Australia)
The Mid West region is one of the nine regions of Western Australia. It is a sparsely populated region extending from the west coast of Western Australia, about north and south of its administrative centre of Geraldton, Western Australia, Geraldton and inland to east of Wiluna, Western Australia, Wiluna in the Gibson Desert. It has a total area of , and a permanent population of about 52,000 people, more than half of those in Geraldton. Earlier names The western portion of this region was known earlier as "The Murchison" based on the Murchison River (Western Australia), river of the same name, and the similarly named Goldfield. Economy The Mid West region has a diversified economy that varies with the geography and climate. Near the coast, annual rainfall of between allows intensive agriculture. Further inland, annual rainfall decreases to less than , and here the economy is dominated by mining of iron ore, gold, nickel and other mineral resources. Geraldton is an imp ...

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] |
Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

Wongan Hills, Western Australia
Wongan Hills is a town in the Shire of Wongan-Ballidu, in the Wheatbelt region of Western Australia. The town is approximately 182 km north of the state capital Perth, at an altitude of 286 metres. The town is named for a nearby range of hills that are found to the north-west of the town, also named Wongan Hills, which was first recorded in 1836 by Surveyor General of Western Australia John Septimus Roe. History The area was settled by the 1900s, and in 1911 the town was gazetted and named after the range. "Wongan" is derived from the Indigenous Australian name "wangan-katta", "wanka" and "woongan". "Katta" is known to mean "hill", but the meaning of "wongan" is uncertain. It may be related to "kwongan", an indigenous word for sandplain, or "whispering", in which case "wongan katta" would mean "whispering hills" (katta is a word for hill). In the early 1900s, poet Lilian Wooster Greaves lived with her family at Wongan Hills. Her book of poetry includes a number of pros ...

Wheatbelt (Western Australia)
The Wheatbelt is one of nine regions of Western Australia defined as administrative areas for the state's regional development, and a vernacular term for the area converted to agriculture during colonisation. It partially surrounds the Perth metropolitan area, extending north from Perth to the Mid West region, and east to the Goldfields–Esperance region. It is bordered to the south by the South West and Great Southern regions, and to the west by the Indian Ocean, the Perth metropolitan area, and the Peel region. Altogether, it has an area of (including islands). The region has 42 local government authorities, with an estimated population of 75,000 residents. The Wheatbelt accounts for approximately three per cent of Western Australia's population. Ecosystems The area, once a diverse ecosystem, reduced when clearing began in the 1890s with the removal of plant species such as eucalypt woodlands and mallee, is now home to around 11% of Australia's critically end ...

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 ...

Leslie Pedley
Leslie Pedley (19 May 1930 – 27 November 2018)IPNILeslie Pedley/ref> was an Australian botanist who specialised in the genus ''Acacia''. He is notable for bringing into use the generic name ''Racosperma'', creating a split in the genus, which required some 900 Australian species to be renamed, because the type species of ''Acacia'', ''Acacia nilotica'', now ''Vachellia nilotica'', had a different lineage from the Australian wattles. However, the International Botanical Congress (IBC), held in Melbourne in 2011, ratified its earlier decision to retain the name ''Acacia'' for the Australian species, but to rename the African species. See also: ''Acacia'' and ''Vachellia nilotica'' regarding the dispute, anAPNIfor a brief history of the name, ''Racosperma''. In 2018, Japanese botanists Hiroyoshi Ohashi and Kazuaki K.
