Acacia Xanthina
''Acacia xanthina'', commonly known as white stemmed wattle, is a coastal shrub or small tree in the family Fabaceae that is endemic to Western Australia. Description White stemmed wattle usually grows as a dense shrub between in height and is often much wider than it is tall. The trunks and branchlets are often coated with a white powdery substance. Its branches are white or greenish-white, with many bends and twists. Like many other ''Acacia'' species, it has phyllodes rather than true leaves. These are bluish-green, from in length long, and wide. The flower heads are bright yellow and spherical, and occur in group of six to nine, but sometimes up to fifteen. It flowers in late winter and spring between August and October. Taxonomy ''Acacia xanthina'' was first collected in 1839 by James Drummond, and described by George Bentham in 1842. The specific name comes from the Greek ''xanthos'', meaning ''yellow'', and refers to the flowers. Distribution It is native to an ...

George Bentham
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.

Greek Language
Greek ( el, label= Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of l ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabales Of Australia
The Fabales are an order of flowering plants included in the rosid group of the eudicots in the Angiosperm Phylogeny Group II classification system. In the APG II circumscription, this order includes the families Fabaceae or legumes (including the subfamilies Caesalpinioideae, Mimosoideae, and Faboideae), Quillajaceae, Polygalaceae or milkworts (including the families Diclidantheraceae, Moutabeaceae, and Xanthophyllaceae), and Surianaceae. Under the Cronquist system and some other plant classification systems, the order Fabales contains only the family Fabaceae. In the classification system of Dahlgren the Fabales were in the superorder Fabiflorae (also called Fabanae) with three families corresponding to the subfamilies of Fabaceae in APG II. The other families treated in the Fabales by the APG II classification were placed in separate orders by Cronquist, the Polygalaceae within its own order, the Polygalales, and the Quillajaceae and Surianaceae within the Rosa ...

List Of Acacia Species
Several cladistic analyses have shown that the genus ''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 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 as the genus ''Vachellia''.

Department Of The Environment And Energy
The Department of the Environment and Energy (DEE) was an Australian government department in existence between 2016 and 2020. The department was responsible for matters including environment protection and conservation of biodiversity as well as energy policy. It was established in July 2016 by the Turnbull Government after the 2016 federal election. Following the appointment of Scott Morrison as Prime Minister, Josh Frydenberg was elevated to Treasurer of Australia, whereby Frydenberg's previous ministerial positions were separated, with Melissa Price as Minister of the Environment and Angus Taylor as Minister for Energy. Price was reshuffled from her position in 2019, and was replaced by Sussan Ley. By an administrative order issued on 5 December 2019 and effective from 1 February 2020, the environment functions of the department were merged with all functions of the Department of Agriculture, to form the Department of Agriculture, Water and the Environment.

Shark Bay
Shark Bay ( Malgana: ''Gathaagudu'', "two waters") is a World Heritage Site in the Gascoyne region of Western Australia. The http://www.environment.gov.au/heritage/places/world/shark-bay area is located approximately north of Perth, on the westernmost point of the Australian continent. UNESCO's official listing of Shark Bay as a World Heritage Site reads: : History The record of Australian Aboriginal occupation of Shark Bay extends to years BP. At that time most of the area was dry land, rising sea levels flooding Shark Bay between BP and BP. A considerable number of aboriginal midden sites have been found, especially on Peron Peninsula and Dirk Hartog Island which provide evidence of some of the foods gathered from the waters and nearby land areas. An expedition led by Dirk Hartog happened upon the area in 1616, becoming the second group of Europeans known to have visited Australia. (The crew of the '' Duyfken'', under Willem Janszoon, had visited Cape York in 1606 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sand Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called '' ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented s ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for lime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Drummond (botanist)
James Drummond (late 1786 or early 1787 – 26 March 1863) was an Australian botanist and naturalist who was an early settler in Western Australia. Early life James Drummond was born in Inverarity, near Forfar, Angus, Scotland, the eldest son of Thomas Drummond, a gardener and botanist. His younger brother Thomas Drummond (1793–1835) was also a botanist. The latter emigrated to Cuba and died there. Both brothers originally worked with their father on the Fothringham estate in Inverarity. He was baptised on 8 January 1787. His father, Thomas Drummond, was a gardener at Fotheringham estate. Little is known of his early life, but he certainly followed the usual course of apprenticeship leading to his "qualification" as a gardener. In 1808, he was employed by Mr Dickson (most probably George Dickson of Leith Walk, Edinburgh). In the mid-1808, Drummond (aged 21) he was appointed curator of the botanic garden that was being established by the Cork Institution, in t ...

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 reco ...
