Acacia Deltoidea
''Acacia deltoidea'' is a shrub of the genus ''Acacia'' and the subgenus ''Plurinerves'' that is endemic to north western Australia. Description The straggling shrub typically grows to a height of and has glandular-hairy branchlets with persistent subulate upcurved stipules with a length of . Like most species of ''Acacia'' it has phyllodes rather than true leaves. The subsessile, imbricate phyllodes are patent to ascending with a cuneate to elliptic to triangular or broadly obdeltate shape. The leathery and glabrous phyllodes are in length and wide and have three to four distant, slightly raised main nerves. It blooms from March to August and produces yellow flowers. Taxonomy There are two recognised subspecies: *''Acacia deltoidea'' subsp. ''ampla'' *''Acacia deltoidea'' subsp. ''deltoidea'' Distribution It is native to an area in the West Kimberley region of Western Australia from along the Bonaparte Archipelago and Napier Bay in the west to around the Phillips Range, Ki ...

Allan Cunningham (botanist)
Allan Cunningham (13 July 1791 – 27 June 1839) was an English botany, botanist and List of explorers, explorer, primarily known for his travels in Australia to collect plants. Early life Cunningham was born in Wimbledon, London, Wimbledon, Surrey, England, the son of Allan Cunningham (head gardener at Wimbledon Park House), who came from Renfrewshire, Scotland, and his English wife Sarah (née Juson/Jewson née Dicken). Allan Cunningham was educated at a Putney private school, Reverend John Adams (educational writer), John Adams Academy and then went into a solicitor's office (a Lincoln's Inn Conveyancer). He afterwards obtained a position with William Townsend Aiton superintendent of Royal Botanic Gardens, Kew, Kew Gardens, and this brought him in touch with Robert Brown (Scottish botanist from Montrose), Robert Brown and Joseph Banks, Sir Joseph Banks. Brazil and Australia (New South Wales) On Banks' recommendation, Cunningham went to Brazil with James Bowie (botani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beverley Springs Station
Beverley is a market and minster town and a civil parish in the East Riding of Yorkshire, England, of which it is the county town. The town centre is located south-east of York's centre and north-west of City of Hull. The town is known for Beverley Minster, Beverley Westwood, North Bar (a 15th-century gate) and Beverley Racecourse. It inspired the naming of the city of Beverly, Massachusetts, which in turn was the impetus for Beverly Hills, California.Marc Wanamaker, ''Early Beverly Hills'', Mount Pleasant, South Carolina: Arcadia Publishing, 2005, pp. 17–1/ref> The town was listed in the 2018 ''Sunday Times'' report on Best Places to Live in northern England. The town was originally known as ''Inderawuda'' and was founded around 700 AD by Saint John of Beverley during the time of the Anglian kingdom of Northumbria. After a period of Viking control, it passed to the Cerdic dynasty, a period during which it gained prominence in terms of religious importanc ...
