Acacia Excentrica
''Acacia excentrica'' is a shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae'' native to Western Australia. Description The prostrate, domed or spreading prickly shrub typically grows to a height of . The stipules are in length. It has green phyllode Phyllodes are modified petioles or leaf stems, which are leaf-like in appearance and function. In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether. Thus the phyllode comes to serve the ...s with a narrowly elliptic to oblong-elliptic and sometimes lanceolate shape. Each slightly asymmetric phyllode is in length and wide and is sharply pungent. It produces yellow flowers from July to October. Each simple inflorescence has one or two headed racemes with a length of . The spherical flower heads have a diameter of and contain 20 to 30 golden yellow flowers. Seed pods form later that are linear with one or two coils. Taxonomy The species was fir ...

Joseph Maiden
Joseph Henry Maiden (25 April 1859 – 16 November 1925) was a botanist who made a major contribution to knowledge of the Australian flora, especially the genus ''Eucalyptus''. This botanist is denoted by the author abbreviation when citing a botanical name. Life Joseph Maiden was born in St John's Wood in northwest London. He studied science at the University of London, but due to ill health he did not complete the course. As part of his treatment he was advised to take a long sea voyage, and so in 1880 he sailed for New South Wales. In 1881, Maiden was appointed first curator of the Technological Museum in Sydney (now the Powerhouse Museum), remaining there until 1896. While there, he published an article in 1886 describing what he called "some sixteenth century maps of Australia". These were the so-called Dieppe maps, the Rotz (1547), the Harleian or Dauphin (mid-1540s), and the Desceliers (1550), photo-lithographic reproductions of which had been published by the Briti ...

Plants Described In 1928
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Acacias Of Western Australia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, Acacia'' is not monophyletic. While the subg. ''Acacia'' and subg. ''Phyllodinae'' are monophyletic, subg. ''Aculeiferum'' is not. This subgenus consists of three clades. Therefore, the following list of ''Acacia'' species cannot be maintained as a single entity, and must either be split up, or broadened to include species previously not in the genus. This genus has been provisionally divided into 5 genus, genera, ''Acacia'', ''Vachellia'', ''Senegalia'', ''Acaciella'' and ''Mariosousa''. The proposed type species of ''Acacia'' is ''Acacia penninervis''. Which of these segregate genera is to retain the name ''Acacia'' has been controversial. The genus was previously typified with the African species ''Acacia scorpioides'' (L.) W.F.Wright, a synonym of ''Acacia nilotica'' (L.) Delile. Under the original typification, the name ''Acacia'' would stay with the group of species currently recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cocklebiddy, Western Australia
Cocklebiddy is a small roadhouse community located on the Eyre Highway in Western Australia. It is the third stop after Norseman on the journey east across the Nullarbor Plain. The area is noted for its caves and lakes. It is the nearest locality to the south coast feature of Twilight Cove, which is 26 km to the south. Cocklebiddy follows the time zone used by Eucla of UTC+8:45. it is situated 284km from Border Village History Cocklebiddy started as an Aboriginal mission station, of which only the stone foundations remain today. The area was thought to be a potential water source and, during World War II, Army engineers attempted to tap fresh water from the lakes, but it was found that a thin skin of fresh water overlay a vast volume of saline water. The Eyre Telegraph Station, located south of the settlement, operated from 1897 until 1929. Unlike most others, it remained in a relatively well-preserved state due to its isolation and protection from the Southern Ocea ...

Kondinin, Western Australia
Kondinin is a town located in the eastern Wheatbelt region of Western Australia, east of the state capital, Perth via the Brookton Highway and State Route 40 between Corrigin and Hyden. It is one of three towns in the Shire of Kondinin. At the 2006 census, Kondinin had a population of 311. History The first European known to have visited the Kondinin area was Captain John Septimus Roe, Surveyor General of the Swan River Colony on his 1848–1849 expedition to examine the south coast. He encountered a group of Aboriginal people east of Nalyaring (near Brookton) who guided the expedition party to several water sources before leaving the party at Yeerakine (just south-east of Kondinin) as this was the limit of their territory. The lake and well nearby came to be known as Kondinin, although the meaning is unknown. In the early years, settlers occasionally encountered groups of Aborigines hunting possums. Although artifacts such as grinding stones and stone choppers have been f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Wheatbelt (Western Australia)
The Wheatbelt is one of nine regions of Western Australia defined as administrative areas for the state's regional development, and a vernacular term for the area converted to agriculture during colonisation. It partially surrounds the Perth metropolitan area, extending north from Perth to the Mid West region, and east to the Goldfields–Esperance region. It is bordered to the south by the South West and Great Southern regions, and to the west by the Indian Ocean, the Perth metropolitan area, and the Peel region. Altogether, it has an area of (including islands). The region has 42 local government authorities, with an estimated population of 75,000 residents. The Wheatbelt accounts for approximately three per cent of Western Australia's population. Ecosystems The area, once a diverse ecosystem, reduced when clearing began in the 1890s with the removal of plant species such as eucalypt woodlands and mallee, is now home to around 11% of Australia's critically end ...
