Eucalyptus Platydisca
''Eucalyptus platydisca'', also known as Jimberlana mallee, is a species of eucalypt native to Western Australia. It is listed as " Threatened Flora (Declared Rare Flora — Extant)" under the Western Australian Government '' Biodiversity Conservation Act 2016'' and as "vulnerable" under the Australian Government ''Environment Protection and Biodiversity Conservation Act 1999''. Description The mallee typically grows to a height of approximately and has smooth mottled grey bark. The erect, multistemmed tree is able to resprout from its lignotuber after fire. The stiff, narrow and dull grey-green adult leaves form an open crown. The diamond shaped buds are found in the leaf axils of leaves in groups of seven. Each bud is in length and wide with white flowers. The cup-shaped fruit that form later have a flattish top and a width of . Taxonomy and naming ''Eucalyptus platydisca'' was first described in 1998 by Lawrie Johnson and Ken Hill in an unpublished manuscript, from mate ...

Lawrence Alexander Sidney Johnson
Lawrence Alexander Sidney Johnson FAA, (26 June 1925 – 1 August 1997) known as Lawrie Johnson, was an Australian taxonomic botanist. He worked at the Royal Botanic Gardens, Sydney, for the whole of his professional career, as a botanist (1948–1972), Director (1972–1985) and Honorary Research Associate (1986–1997). - originally published in ''Historical Records of Australian Science'', vol.13, no.4, 2001. Alone or in collaboration with colleagues, he distinguished and described four new families of vascular plants, 33 new genera, 286 new species (including posthumous publications), and reclassified another 395 species. Of the families he described, Rhynchocalycaceae (with B. G. Briggs, 1985) is accepted by the Angiosperm Phylogeny Group (APG). Hopkinsiaceae and Lyginiaceae, (which he and B. G. Briggs proposed in 2000 be carved out of Anarthriaceae), have not been accepted by the APG. Lawrie Johnson died of cancer in 1997. He received many honours and awards, inclu ...

Eucalyptus Diversifolia
''Eucalyptus diversifolia'', commonly known as the soap mallee, coastal white mallee, South Australian coastal mallee, or coast gum is a species of mallee that is endemic to an area along the southern coast of Australia.

Eucalypts Of Western Australia
Eucalypt is a descriptive name for woody plants with capsule fruiting bodies belonging to seven closely related genera (of the tribe Eucalypteae) found across Australasia: ''Eucalyptus'', '' Corymbia'', '' Angophora'', '' Stockwellia'', ''Allosyncarpia'', '' Eucalyptopsis'' and ''Arillastrum''. Taxonomy For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''. Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group. The extant genera ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' comprise si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have b ...

Department Of Environment And Conservation (Western Australia)
The Department of Environment and Conservation (DEC) was a department of the Government of Western Australia that was responsible for implementing the state's conservation and environment legislation and regulations. It was formed on 1 July 2006 by the amalgamation of the Department of Environment and the Department of Conservation and Land Management. The DEC was separated on 30 June 2013 forming the Department of Parks and Wildlife (DPaW) and the Department of Environment Regulation (DER), which both commenced operations on 1 July 2013. On 1 July 2017 the DER amalgamated with the Department of Water and the Office of the Environmental Protection Authority, to become the Department of Water and Environmental Regulation, while DPaW was merged with other agencies to form the Department of Parks and Wildlife. Status (at dissolution, 30 June 2013) The department was managing more than 285,000 km2, including more than nine per cent of WA's land area: its national parks, mar ...

Triodia (plant)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Granite
Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or '' granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is near ...

CSIRO
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949, further legislated changes included renaming the organisation as CSIRO. Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
