Lindl
John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich School. He would have liked to go to university or to buy a commission in the army but the family could not afford either. He became Belgian agent for a London seed merchant in 1815. At this time Lindley became acquainted with the botanist William Jackson Hooker who allowed him to use his botanical library and who introduced him to Sir Joseph Banks who offered him employment as an assistant in his ...

Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciat ...

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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimberley (Western Australia)
The Kimberley is the northernmost of the nine regions of Western Australia. It is bordered on the west by the Indian Ocean, on the north by the Timor Sea, on the south by the Great Sandy and Tanami deserts in the region of the Pilbara, and on the east by the Northern Territory. The region was named in 1879 by government surveyor Alexander Forrest after Secretary of State for the Colonies John Wodehouse, 1st Earl of Kimberley. History The Kimberley was one of the earliest settled parts of Australia, with the first humans landing about 65,000 years ago. They created a complex culture that developed over thousands of years. Yam ('' Dioscorea hastifolia'') agriculture was developed, and rock art suggests that this was where some of the earliest boomerangs were invented. The worship of Wandjina deities was most common in this region, and a complex theology dealing with the transmigration of souls was part of the local people's religious philosophy. In 1837, with expedit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walcott Inlet
Walcott Inlet is an estuary located in the Kimberley region of Western Australia. It flows into Collier Bay, in the Indian Ocean, via a narrow gap known as Yule Entrance. The inlet was named on 19 June 1865 by Trevarton Charles Sholl after Stephen Walcott, Commissioner of the Government Emigration Board, while on an exploratory expedition from the short-lived Camden Harbor settlement (in Camden Sound). The inlet is in length, with a width of and covering an area of . It is tide-dominated, but in nearly pristine condition with a catchment area of . The entry to the inlet, known as Yule Entrance, On the Department of Agriculture, Water and the Environment websithere Date assumed per last date mentioned in publication (2010), and author as per website. is in length and as little as wide. The mean tidal range at the mouth is , but can reach , leading to turbulence, strong tidal flows and whirlpools. Three large rivers flow into the eastern end of the inlet: Charnley Riv ...

Prince Regent National Park
Prince Regent National Park, formerly the Prince Regent Nature Reserve, is a protected area in the Kimberley region of Western Australia. In 1978 the area was nominated as a UNESCO World Biosphere Reserve. Land The national park covers a total area of and was created in 1964 to protect the catchment area of the Prince Regent River. The northern boundary of the national park abuts the southern boundary of the Mitchell River National Park creating a protected area of over . The landscape of the reserve ranges from lush rainforest to sandstone plains. The area contains gorges, waterfalls, cliffs and mountain ranges. Careening Bay, on Coronation Island, site of "The Mermaid Tree" (after , Philip Parker King's ship) is within the park. The boab tree was inscribed by the ship's carpenter when the vessel was deliberately careened (beached) in order to undertake repairs.

Xanthostemon
''Xanthostemon'' is a genus of trees and shrubs, constituting part of the myrtle plant family Myrtaceae. This genus was first described in 1857 by German–Australian botanist Ferdinand von Mueller. According to different official sources between 46 and 51 species are known to science. They grow naturally in New Caledonia, Australia, the Solomon Islands and Malesia, including the Philippines, New Guinea and Indonesia. The genera ''Pleurocalyptus'' and ''Purpureostemon'' from New Caledonia are morphologically close to ''Xanthostemon''.

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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1982
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 lost the abil ...
