Banksia Sessilis Var. Cordata
''Banksia sessilis'' var. ''cordata'' is a variety of ''Banksia sessilis'' (Parrot Bush), with unusually large leaves and flower heads. It is a rare variety that is restricted to the extreme south-west corner of Western Australia. Description This variety is similar to other varieties of ''B. sessilis'', but has larger leaves; these may be up to six centimetres long and four centimetres wide in this variety, whereas in ''B. sessilis'' var. ''sessilis'' they are commonly two to three centimetres long. The leaves of this variety are also a darker green than the other varieties, and its flower heads are generally larger. Taxonomy This variety was first published as a variety of ''Dryandra floribunda'' (now ''B. sessilis'') by Carl Meissner in the second volume of ''Plantae Preissianae'', published in 1848. It was based on a type specimen collected by James Drummond; this specimen was said to have been collected at the Swan River, where this variety does not now ...

Carl Meissner
Carl Daniel Friedrich Meissner (1 November 1800 – 2 May 1874) was a Swiss botanist. Biography Born in Bern, Switzerland on 1 November 1800, he was christened Meisner but later changed the spelling of his name to Meissner. For most of his 40-year career he was Professor of Botany at University of Basel. He made important contributions to the botanical literature, including the publication of the comprehensive work ''Plantarum Vascularum Genera'', and publications of monographs on the families Polygonaceae (especially the genus '' Polygonum''), Lauraceae, Proteaceae, Thymelaeaceae and Hernandiaceae. His contributions to the description of the Australian flora were prolific; he described hundreds of species of Australian Proteaceae, and many Australian species from other families, especially Fabaceae, Mimosaceae and Myrtaceae. His health deteriorated after 1866, and he was less active. He died in Basel , french: link=no, Bâlois(e), it, Basilese , neighboring_munic ...

Alex George (botanist)
Alexander Segger George (born 4 April 1939) is a Western Australian botanist. He is the authority on the plant genera ''Banksia'' and ''Dryandra''. The "bizarre" Restionaceae genus '' Alexgeorgea'' was named in his honour in 1976. Early life Alex Segger George was born in Western Australia on 4 April 1939. Career George joined the Western Australian Herbarium as a laboratory assistant at the age of twenty in 1959. He worked under Charles Gardner for a year before the latter's retirement, and partly credits him with rekindling an interest in banksias. In 1963 he graduated with a Bachelor of Arts from the University of Western Australia, and the following year added a botany major. Continuing at the Western Australian Herbarium as a botanist, in 1968 he was seconded as Australian Botanical Liaison Officer at the Royal Botanic Gardens in London. George also has an interest in history, especially historical biography of naturalists in Western Australia. He has published a number ...

Endemic Flora Of Western Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Ser
''Banksia'' is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes, and fruiting "cones" and heads. ''Banksias'' range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts. Heavy producers of nectar, ''banksias'' are a vital part of the food chain in the Australian bush. They are an important food source for nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Further, they are of economic importance to Australia's nursery and cut flower industries. However, these plants are threatened by a number of processes including land clearing, frequent burning and disease, and a number of species are rare and endangere ...

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, '' Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative prot ...

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.

Heath (habitat)
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered location ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denmark, Western Australia
Denmark is a coastal town located on Wilson Inlet in the Great Southern region of Western Australia, south-south-east of the state capital of Perth. At the 2016 census, Denmark had a population of 2,558; however, the population can be several times the base population during tourist seasons. History '' 't Landt van de Leeuwin'' (Leeuwin's Land) was the original Dutch name for the area from King George Sound to the Swan River. It was named after the Dutch East Indiaman , which sighted the coast from Hamelin Bay to Point D'Entrecasteaux in 1622. The coastline of the Denmark area was observed in 1627 by the Dutchman François Thijssen, captain of the ship (The Golden Seahorse), who sailed to the east as far as Ceduna in South Australia and back. Captain Thijssen had seen the south coast of Australia and charted about of it between Cape Leeuwin and the Nuyts Archipelago. Two centuries later, when the first Europeans entered the lands around the present Denmark, the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point D'Entrecasteaux
Point D'Entrecasteaux is a point on the south coast of Western Australia. The first European sighting was by the Frenchman Antoine Bruni d'Entrecasteaux in the 1700s, although there were possible sightings by Dutch navigators from ships such as '' Leeuwin'' in the 1600s. The nearest populated site on the coast is Windy Harbour to the east of the point, and Northcliffe to the north. The point is located within the D'Entrecasteaux National Park. The main location west on the coast is Cape Leeuwin, and to the east is Point Nuyts. There are named islands near the point, including Quagering Island Quagering Island (also known as Flat Island) is an island off the south coast of Western Australia, located near Windy Harbour, and along with Sandy Island makes the Quagering Nature Reserve. See also * D'Entrecasteaux National Park *The Cow ... and Sandy Island. It has been a site of material found from the ocean. There also had been reports of heavy sea conditions in ...

Cape Leeuwin
Cape Leeuwin is the most south-westerly (but not most southerly) mainland point of the Australian continent, in the state of Western Australia. Description A few small islands and rocks, the St Alouarn Islands, extend further in Flinders Bay to the east of the cape. The nearest settlement, north of the cape, is Augusta. South-east of Cape Leeuwin, the coast of Western Australia extends much further south. Cape Leeuwin is not the southernmost point of Western Australia, with that distinction belonging to West Cape Howe, which is to the southeast, near Albany. In Australia, the cape is considered where the Indian Ocean meets the Southern Ocean, but most other nations and bodies consider that the Southern Ocean exists only south of 60°S. Located on headland of the cape is the Cape Leeuwin Lighthouse and the buildings that were used by the lighthouse-keepers. Cape Leeuwin is considered one of the three " great capes" of the world. Use of name Cape Leeuwin is often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Warren (biogeographic Region)
Warren, also known as Karri Forest Region and the Jarrah-Karri forest and shrublands ecoregion, is a biogeographic region in southern Western Australia. Located in the southwest corner of Western Australia between Cape Naturaliste and Albany, it is bordered to the north and east by the Jarrah Forest region. Its defining characteristic is an extensive tall forest of '' Eucalyptus diversicolor'' (karri). This occurs on dissected, hilly ground, with a moderately wet climate. Karri is a valuable timber and much of the karri forest has been logged over, but less than a third has been cleared for agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), and as a terrestrial ecoregion by the World Wide Fund for Nature, it was first defined by Ludwig Diels in 1906. Geography and geology The Warren region is defined as the coastal sandplain between Cape Naturaliste and Albany. Extending from the ocean to the edge of the Yilgarn crato ...
