Augustus Oldfield
Augustus Frederick Oldfield (1821–1887) was an English botanist and zoologist who made large collections of plant specimens in Australia. Oldfield was born on 12 January 1821 in London, England. He made botanical collections in Tasmania, the coastal regions of Western Australia, and on the Nullarbor Plain. Records of his journey note him walking from Sydney to Melbourne, and collections at Twofold Bay, the Huon Valley and mountains in Tasmania, and other regions in the 1850s and 60s. The large body of material in the west of the country was collected from King George Sound to the Murchison River, and he travelled across the Nullarbor to Adelaide. Oldfield published a paper 'On the Aborigines of Australia' in 1865, a detailed survey of the cultural practices of the peoples living near Port Gregory. He died on 22 May 1887, after returning to London in 1862. His main collection was deposited at the National Herbarium of Victoria, Royal Botanic Gardens Victoria, by Ferdinand von ...

Rosids Of Western Australia
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids may have originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's broadleaved forests are dominated by rosid species, which in turn help with diversification in many other living lineages. Additionally, rosid herbs and shrubs are a significant part of arctic/alpine and temperate floras. The clade also includes some aquatic, desert and parasitic plants. Name The name is based upon the name " Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the na ...

Endemic Flora Of Western Australia
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Calytrix
''Calytrix'' is a genus of about 83 species of flowering plants, commonly known as star flowers, in the family Myrtaceae and is endemic to Australia. Plants in the genus ''Calytrix'' are small to large shrubs with small, spreading and more or less round leaves, the flowers arranged singly in leaf axils. The flowers are Monoicy, bisexual with 5 overlapping sepals with a long Awn (botany), awn, and many stamens. Description Plants in the genus ''Calytrix'' are dwarf to large shrubs with overlapping or widely-spaced leaves, but with stipules absent or small. The flowers are arranged singly in leaf axils with 2 Bract#Bracteole, bracteoles at the base. The Hypanthium, floral tube is usually long and tube-shaped with 5 overlapping sepals with a long awn on the end and 5 lance-shaped to elliptic petals that are free from each other and fall from the flower as it develops. There are many stamens, in one to several Whorl (botany), whorls. The fruit is a small, dry Nut (fruit), nut conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Biodiversity, Conservation And Attractions (Western Australia)
The Department of Biodiversity, Conservation and Attractions (DBCA) is the Government of Western Australia, Western Australian government department responsible for managing lands and waters described in the ''Conservation and Land Management Act 1984'', the ''Rottnest Island Authority Act 1987'', the ''Swan and Canning Rivers Management Act 2006'', the ''Botanic Gardens and Parks Authority Act 1998'', and the ''Zoological Parks Authority Act 2001'', and implementing the state's conservation and environment legislation and regulations. The Department reports to the Minister for Environment and the Minister for Tourism. DBCA was formed on 1 July 2017 by the merger of the Department of Parks and Wildlife (DPaW), the Botanic Gardens and Parks Authority, the Zoological Parks Authority and the Rottnest Island Authority. The former DPaW became the Parks and Wildlife Service. Status Parks and Wildlife Service The Formerly Department of Parks and Wildlife. the Parks and Wildlife Servi ...

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 Western Australian Herbarium is the state Herbarium, situated in Perth, the capital of Western Australia. It houses a collection of more than 845,000 dried specimens of plants, algae, bryophytes (mosses, liverworts and hornworts), lichens, fu .... 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 n ...

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles, bottlebrushes or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on Australia's Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
