Gastrolobium Praemorsum
''Gastrolobium praemorsum'' is a scrambling shrub which is endemic to the south-west of Western Australia. It is a member of the family Fabaceae and produces red pea-flowers from late winter to early summer (August to December in Australia). It is not known whether this species shares the toxic properties of many other members of the genus'' Gastrolobium''. Taxonomy The species was first formally described by botanist Carl Meissner and published in ''Plantae Preissianae'' in 1844. Meissner assigned it the name ''Brachysema praemorsa''. In 2002 botanists Gregory Chandler and Michael Crisp reassigned this species to the genus ''Gastrolobium'' along with other ''Brachysema'' species. Distribution It is found between Geographe Bay and Albany. An isolated population at Bullsbrook north of 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geographe Bay
Geographe Bay is in the south-west of Western Australia around 220 km southwest of Perth. The bay was named in May 1801 by French explorer Nicolas Baudin, after his ship, ''Géographe''. The bay is a wide curve of coastline extending from Cape Naturaliste past the towns of Dunsborough and Busselton, ending near the city of Bunbury. The bay is protected from the rough seas of the Indian Ocean by Cape Naturaliste (named after ''Naturaliste''), which makes it a popular destination for recreational boaters. The bay is extremely shallow, limiting the entrance of large ships. To alleviate this problem the two-kilometre-long Busselton Jetty, the longest in the southern hemisphere, was built. The Royal Australian Navy frigate was sunk in the bay off the town of Dunsborough on 14 December 1997, for use as a dive wreck. The bay attracts whale watchers, who see it as an alternative to Flinders Bay. The north west part of the bay is the location of a number of surf breaks. ...

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] |
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 originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. 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 name "Rosidae" is a description of a group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perth, Western Australia
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 stat ...

Bullsbrook, Western Australia
Bullsbrook (formerly Bullsbrook East) is a northern suburb of Perth, Western Australia in the outer metropolitan area. It is located in the City of Swan. The original Bullsbrook townsite is located slightly west of the current town, on the 17 km mark of the Midland Railway. Bullsbrook is also home to the RAAF Pearce airbase, a major training facility for the Royal Australian Air Force. The suburb is situated on the Great Northern Highway, 25 kilometres north of the Midland Strategic Regional Centre. It is well serviced by several major transport networks including the Great Northern Highway, Railway Parade and the Brand Highway to the north, Chittering Road to the east and Neaves Road to the west. Bullsbrook is also adjacent to the State rail network, providing an opportunity for the development of an intermodal freight transport hub. The site is further strengthened by linkage to the planned Perth-Darwin National Highway via Stock Road. Although traditionally a predominantl ...

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 ...

Brachysema
''Gastrolobium'' is a genus of flowering plants in the family Fabaceae. There are over 100 species in this genus, and all but two are native to the south west region of Western Australia. A significant number of the species accumulate monofluoroacetate (the key ingredient of the poison known commonly as 1080), which caused introduced/non native animal deaths from the 1840s in Western Australia. The controversy over the cause of the stock poisoning in that time involved the botanist James Drummond in a series of tests to ascertain the cause of the poisoning, which was determined to be caused primarily by the plants York Road poison (''G. calycinum'') and Champion Bay poison (''G. oxylobioides''). In the 1930s and 1940s C.A. Gardner and H.W. Bennetts identified other species in Western Australia, leading to the publication of ''The Toxic Plants of Western Australia'' in 1956. The base chromosome number of ''Gastrolobium'' is 2''n'' = 16. Species ''Gastrolobium'' comprises the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 on 2 May 1874. See also * Meissner's taxonomic arrangement of Banksia Carl ...
