Taxa Named By Russell Lindsay Barrett
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 2013
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 ability t ...

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] |
Triodia (plant)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Owenia Vernicosa
''Owenia vernicosa'', the emu apple, is a species of tree found in the north of Australia. The bark is an orange-grey colour that flakes away from the trunk. Deep red fruit appear after the flowering period, when the white, cream and green inflorescence appears in October to November. The tree occurs on alluvial sand or black and loamy clays over sandstone. The habitat may be rocky ridge lines and slopes or alongside creeks. Uses Indigenous Australians pulverized the inner bark of this species and added it to small water bodies to act as a fish toxin, allowing fish to be easily collected from the surface of the water. Indigenous Australians boiled the inner bark of this species in water and the resulting liquid was used as an antiseptic wash for open cuts and sores. Emus are known to consume the fruit of this species. Red-tailed black cockatoos likely consume the fruit of this species, as indicated by the meaning of indigenous language words for this species.

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] |
Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...
