''Acacia claviseta'', also known as the club-tipped whorled wattle, is a shrub belonging to the genus ''Acacia'' and the subgenus ''Lycopodiifoliae'' that is endemic to north western Australia. Description The slightly viscid shrub typically grows to a height of and has an erect habit with many branches. The densely woolly yellow to white haired branchlets have setose stipules with a length of . Like most species of ''Acacia'' it has phyllodes rather than true leaves. The evergreen phyllodes occur in crowded whorls of 9 to 15. The erect to ascending phyllodes are in length and wide and are terete to more or less flat, well haired and have longitudinal nerves that are not visible. It blooms between February and March and July and August producing yellow flowers.

Bruce Maslin
Bruce Roger Maslin (born 3 May 1946) is an Australian botanist, known for his work on ''Acacia'' taxonomy. Born in Bridgetown, Western Australia, he obtained an honours degree in botany from the University of Western Australia in 1967, then took up an appointment as a botanist with the Western Australian Herbarium. The following year he was conscripted to serve in the Vietnam War; he gave three years in National Service, serving in Vietnam in 1969. In 1970 he returned to his position at the Western Australian Herbarium, serving in that institution until 1987. During this time he was Australian Botanical Liaison Officer in 1977 and 1978; editor of ''Nuytsia ''Nuytsia floribunda'' is a hemiparasitic tree found in Western Australia.

Bedford Downs Station
Bedford Downs, or Bedford Downs Station, is a pastoral lease that operates as a cattle station in Western Australia. It is situated about west of Warmun and north of Halls Creek in the Kimberley region. Both the station and nearby Mount Bedford were named in 1903 after Admiral Frederick Bedford, who was the Governor of Western Australia. Established some time prior to 1906 by the Buchanan and Gordon Brothers, the property experienced many difficulties including the spearing of cattle and isolation of the area. In two years nearly a dozen men had also been murdered by the traditional owners. The family business, Quilty and Sons, acquired the property in 1917 from Messrs, Mather, Ross, Manning and Ralston for £34,000. The property was stocked with 8,500 head of cattle and 80 horses. Patrick Quilty was left to manage Bedford Downs while his brother Tom Quilty managed Euroka Springs Station in the Northern Territory. A boundary rider named Harry Annear was murdered by Ab ...

Taxa Named By Bruce Maslin
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 th ... [...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] |
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] |

Warmun, Western Australia
Warmun Community (also known as Turkey Creek) and Warmun are a township and locality in the Kimberley region of Western Australia, located on the Great Northern Highway, northeast of Perth, Western Australia. The closest populated town is Halls Creek, about to the south. It is about south of Kununurra. Turkey Creek is a small creek that runs through the community. History The Gija people are the traditional owners of the area, having inhabited it for thousands of years. The area was settled by European pastoralists in the 19th century but the community was established in 1901 when the state government built a ration depot at Turkey Creek. Mistake Creek massacre In March 1915, Michael Rhatigan, a telegraph linesman based at Turkey Creek, together with his two Aboriginal employees, Joe Wynne and Nipper, shot dead twelve Gija people at Mistake Creek in the East Kimberley, in an incident which became known as the Mistake Creek massacre. They initially rushed an Aboriginal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
