Acacia Polystachya
''Acacia polystachya'' is a tree belonging to the genus ''Acacia'' and the subgenus ''Juliflorae'' that is native to north eastern Australia. Description The tree typically grows to a height of and has dark brown to grey coloured bark that is smooth of corrugated. It has smooth to pustular, flattened or angular branchlets that are grey, brown or purplish in colour. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The narrowly elliptic phyllodes are sometimes asymmetrical and straight to sickle shaped. The glabrous and chartaceous phyllodes are in length and and have two to three prominent nerves. It blooms between April and July producing yellow flowers. The flower-spikes are in length and are loosely arranged with bands of pale yellow flowers. The thinly coriaceous blackish seed pods that form after flowering have a linear shape and are straight-sided to slightly and often constricted between seeds and covered in a powdery white coating. The glabro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benth
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800.Jean-Jacques Amigo, « Bentham (George) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p.

Endemism
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] |

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] |
Alluvial
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm Island, Queensland
Palm Island is a locality consisting of an island group of 16 islands, split between the Shire of Hinchinbrook and the Aboriginal Shire of Palm Island, in Queensland, Australia. The locality coincides with the geographical entity known as the Palm Island group, also known as the Greater Palm group, originally named the Palm Isles. In the , Palm Island had a population of 2,455 people. Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License However, the term "Palm Island" is most often used to refer to the main island, Great Palm Island, the largest island in the group and the only one with a significant population of permanent residents, most of whom are Aboriginal. The island is also known by the name "Bwgcolman", meaning "one people from many groups", derived from an Aboriginal language of one of the earliest groups of Aboriginal people removed from the mainland and settled there from 1918 onwards, during its ...

Cairns, Queensland
Cairns (, ) is a city in Queensland, Australia, on the tropical north east coast of Far North Queensland. The population in June 2019 was 153,952, having grown on average 1.02% annually over the preceding five years. The city is the 5th-most-populous in Queensland, and 15th in Australia. The city was founded in 1876 and named after Sir William Wellington Cairns, following the discovery of gold in the Hodgkinson river. Throughout the late 19th century, Cairns prospered from the settlement of Chinese immigrants who helped develop the region's agriculture. Cairns also served as a port for blackbirding ships, bringing slaves and indentured labourers to the sugar plantations of Innisfail. During World War II, the city became a staging ground for the Allied Forces in the Battle of the Coral Sea. By the late 20th century the city had become a centre of international tourism, and in the early 21st century has developed into a major metropolitan city. Cairns is a popular tourist ...

Cape York Peninsula
Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, R.E. et al. (2002). Wilderness: Earth’s last wild places. Mexico City: Agrupación Sierra Madre, S.C. The land is mostly flat and about half of the area is used for grazing cattle. The relatively undisturbed eucalyptus-wooded savannahs, tropical rainforests and other types of habitat are now recognised and preserved for their global environmental significance. Although much of the peninsula remains pristine, with a diverse repertoire of endemic flora and fauna, some of its wildlife may be threatened by industry and overgrazing as well as introduced species and weeds.Mackey, B. G., Nix, H., & Hitchcock, P. (2001). The natural heritage significance of Cape York Peninsula. Retrieved 15 January 2008, froepa.qld.gov.au. The northernmost point of the peninsula is Cape York ().

Torres Strait
The Torres Strait (), also known as Zenadh Kes, is a strait between Australia and the Melanesian island of New Guinea. It is wide at its narrowest extent. To the south is Cape York Peninsula, the northernmost extremity of the Australian mainland. To the north is the Western Province of Papua New Guinea. It is named after the Spanish navigator Luís Vaz de Torres, who sailed through the strait in 1606. Prehistory The islands of the Torres Strait have been inhabited by humans for at least 2,500 years and possibly much longer. The various Torres Strait Islander communities have a unique culture and long-standing history with the islands and nearby coastlines. Their maritime-based trade and interactions with the Papuans to the north and the Australian Aboriginal communities have maintained a steady cultural diffusion among the three societal groups, dating back thousands of years. History The first recorded European navigation of the strait was by Luís Vaz de Torres, a pilot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Queensland
North Queensland or the Northern Region is the northern part of the Australian state of Queensland that lies just south of Far North Queensland. Queensland is a massive state, larger than many countries, and its tropical northern part has been historically remote and undeveloped, resulting in a distinctive regional character and identity. Townsville is the largest urban centre in North Queensland, leading it to be regarded as an unofficial capital. The region has a population of 231,628 and covers . Geography There is no official boundary that separates North Queensland from the rest of the state. Unofficially it is usually considered to have a southern border beginning south of the Mackay Region southern boundary, but historically it has been as far south as Rockhampton. To the north is the Far North Queensland region, centred on Cairns and out west is the Gulf Country. A coastal region centred on its largest settlement is the city of Townsville. The city is the location ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Far North Queensland
Far North Queensland (FNQ) is the northernmost part of the Australian state of Queensland. Its largest city is Cairns and it is dominated geographically by Cape York Peninsula, which stretches north to the Torres Strait, and west to the Gulf Country. The waters of Torres Strait include the only international border in the area contiguous with the Australian mainland, between Australia and Papua New Guinea. The region is home to three World Heritage Sites, the Great Barrier Reef, the Wet Tropics of Queensland and Riversleigh, Australia's largest fossil mammal site. Far North Queensland lays claim to over 70 national parks, including Mount Bartle Frere; with a peak of it is the highest peak in both Northern Australia and Queensland. The Far North region is the only region of Australia that is the indigenous country of both Aboriginal Australians and Torres Strait Islanders. Far North Queensland supports a significant agricultural sector, a number of significant mines and is h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
