Prasophyllum Regium
''Prasophyllum regium'', commonly known as the king leek orchid, is a species of orchid endemic to the south-west of Western Australia. It has a single, unusually thick tubular leaf and up to one hundred relatively large, greenish-brown or burgundy-coloured flowers. It is one of the tallest leek orchids, sometimes growing to a height of . Description ''Prasophyllum regium'' is a terrestrial, perennial, deciduous, herb with an underground tuber and a single fleshy, green to blackish, tube-shaped leaf long and wide. Between fifty and one hundred or more flowers are arranged along a flowering spike long, reaching to a height of . The flowers are greenish-brown to burgundy-coloured, long and about wide. As with others in the genus, the flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal is long and wide and the lateral sepals are long, wide and fused to each other. The petals are long, wide and curve forwards. The labell ...

Orchid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Society Of South Australia
The Royal Society of South Australia (RSSA) is a learned society whose interest is in science, particularly, but not only, of South Australia. The major aim of the society is the promotion and diffusion of scientific knowledge, particularly in relation to natural sciences. The society was originally the Adelaide Philosophical Society, founded on 10 January 1853. The title "Royal" was granted by Queen Victoria in October 1880 and the society changed its name to its present name at this time. It was incorporated in 1883. It also operates under the banner Science South Australia. History The origins of the Royal Society are related to the South Australian Literary and Scientific Association, founded in August 1834, before the colonisation of South Australia, and whose book collection eventually formed the kernel of the State Library of South Australia. The Society had its origins in a meeting at the Stephens Place home of J. L. Young (founder of the Adelaide Educational Institut ...

Endemic Orchids Of 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchids Of Western Australia
Among the many wildflowers in Western Australia, there are around four hundred species of orchids. Early identifications One of the first botanists to study Western Australia was Archibald Menzies, aboard HMS ''Discovery'', who explored King George Sound in 1791. Many of the samples (including orchids) were lost in the return to England, but those that did survive were documented in ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', published by Robert Brown in 1810. The first three orchids from Western Australia to be named were ''Caladenia menziesii'' (now '' Leptoceras menziesii''), '' Caladenia flava'', and ''Diuris longifolia''. In 1802 Robert Brown himself collected 500 specimens of flora from Western Australia, including: * ''Diuris emarginata'' var. ''emarginata'' * ''Diuris emarginata'' var. ''pauciflora'' *'' Diuris setacea'' *'' Epiblema grandiflorum'' *''Microtis alba'' *'' Microtis media'' *'' Microtis pulchella'' *'' Prasophyllum gibbosum'' *''Prasoph ...

Prasophyllum
''Prasophyllum'', commonly known as leek orchids, is a genus of about 140 species of flowering plants in the orchid family, Orchidaceae and is found in Australia and New Zealand. The Australian species are found in all states but have not been recorded in the Northern Territory. The common name arises from their having a hollow, leek- or onion-like leaf. Some species only flower after summer fires and have flowers similar to those of ''Xanthorrhoea'' which flower at the same time, suggesting that they employ the same pollinating insects. Leek orchids are similar to those in the genus ''Genoplesium'' except that the free part of the leaf is cylindrical (flat in ''Genoplesium'') and the labellum has a solid (rather than flexible) connection to the column. They range in size from the little laughing leek orchid ('' P. gracile'') at about to the king leek orchid ('' P. regium'') which grows up to tall.

Department Of Parks And Wildlife (Western Australia)
The Department of Parks and Wildlife (DPaW) was the department of the Government of Western Australia responsible for managing lands described in the ''Conservation and Land Management Act 1984'' and implementing the state's conservation and environment legislation and regulations. The minister responsible for the department was the Minister for the Environment. History The Department of Environment and Conservation (DEC) was separated on 30 June 2013, forming the Department of Parks and Wildlife (DPaW) and the Department of Environment Regulation (DER), both of which commenced operations on 1 July 2013. DPaW focused on managing multiple use state forests, national parks, marine parks and reserves. DER focused on environmental regulation, approvals and appeals processes, and pollution prevention.

IBRA
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...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 craton p ...

Jarrah Forest
Jarrah forest is tall open forest in which the dominant overstory tree is ''Eucalyptus marginata'' (jarrah). The ecosystem occurs only in the Southwest Botanical Province of Western Australia. It is most common in the biogeographic region named in consequence Jarrah Forest. Most jarrah forest contains at least one other co-dominant overstory tree; association with ''Corymbia calophylla'' is especially common, and results in which is sometimes referred to as jarrah-marri forest. Considerable amount of research delineates northern, central and southern jarrah forestStrelein, G. J. (1988) ''Site classification in the Southern jarrah forest of Western Australia'' Como, W.A.

Albany, Western Australia
Albany ( ; nys, Kinjarling) is a port city in the Great Southern region in the Australian state of Western Australia, southeast of Perth, the state capital. The city centre is at the northern edge of Princess Royal Harbour, which is a part of King George Sound. The central business district is bounded by Mount Clarence to the east and Mount Melville to the west. The city is in the local government area of the City of Albany. While it is the oldest colonial, although not European, settlement in Western Australia - predating Perth and Fremantle by over two years - it was a semi-exclave of New South Wales for over four years until it was made part of the Swan River Colony. The settlement was founded on 26 December 1826 as a military outpost of New South Wales for the purpose of forestalling French ambitions in the region. To that end, on 21 January 1827, the commander of the outpost, Major Edmund Lockyer, formally took possession for the British Crown of the portion of N ...

Perth
Perth is the capital and largest city of the Australian state of Western Australia. It is the fourth most populous city in Australia and Oceania, with a population of 2.1 million (80% of the state) living in Greater Perth in 2020. Perth is part of the South West Land Division of Western Australia, with most of the metropolitan area on the Swan Coastal Plain between the Indian Ocean and the Darling Scarp. The city has expanded outward from the original British settlements on the Swan River, upon which the city's central business district and port of Fremantle are situated. Perth is located on the traditional lands of the Whadjuk Noongar people, where Aboriginal Australians have lived for at least 45,000 years. Captain James Stirling founded Perth in 1829 as the administrative centre of the Swan River Colony. It was named after the city of Perth in Scotland, due to the influence of Stirling's patron Sir George Murray, who had connections with the area. It gained city statu ...
