Acacia Pachyacra
''Acacia pachyacra'' is a tree or shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae''. that is endemic to arid parts of central and western Australia. Description The bushy slender tree or shrub typically grows to a height of . It branches near or atnnear ground level into a few erect to ascending main stems. It has a soft, dense canopy that produces a hissing sound in windy conditions much the same as a Sheoak ('' Casuarina'' or '' Allocasuarina'') or Athol Pine ('' Tamarix'') would. It has smooth greenish bronze or reddish brown coloured bark that is often covered in a fine white powdery coating that is grey and roughened near the base of the trunks. It blooms from August to October and produces yellow flowers. Taxonomy The species was first formally described by the botanists Joseph Maiden and William Blakely in 1927 as part of the work '' Descriptions of fifty new species and six varieties of western and northern Australian Acacias, and notes on four ...

Joseph Maiden
Joseph Henry Maiden (25 April 1859 – 16 November 1925) was a botanist who made a major contribution to knowledge of the Australian flora, especially the genus ''Eucalyptus''. This botanist is denoted by the author abbreviation when citing a botanical name. Life Joseph Maiden was born in St John's Wood in northwest London. He studied science at the University of London, but due to ill health he did not complete the course. As part of his treatment he was advised to take a long sea voyage, and so in 1880 he sailed for New South Wales. In 1881, Maiden was appointed first curator of the Technological Museum in Sydney (now the Powerhouse Museum), remaining there until 1896. While there, he published an article in 1886 describing what he called "some sixteenth century maps of Australia". These were the so-called Dieppe maps, the Rotz (1547), the Harleian or Dauphin (mid-1540s), and the Desceliers (1550), photo-lithographic reproductions of which had been published by the Briti ...

Mucro
A leaf (plural, : leaves) is any of the principal appendages of a vascular plant plant stem, stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthesis, photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Joseph Maiden
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] |
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] |
Ophthalmia Range
The Ophthalmia Range is a Mountain range, range in the Pilbara region of Western Australia. It is approximately north of Perth, Western Australia, Perth; the nearest town is Newman, Western Australia, Newman, approximately to the south in the Hamersley Range. There are several variations of the spelling of Ophthalmia. History The first recorded sighting of the range was by the explorer Francis Thomas Gregory in 1861. On expedition he noted the obvious iron ore deposits that colour the range. The range was named in 1876 by Ernest Giles; Giles was temporarily blinded when he reached the area after travelling east from the headwaters of the Ashburton River (Western Australia), Ashburton River and had to be led by his second in charge Alec Ross; he named the range after his condition at the time. Giles' vision later recovered and he left unimpressed with the land. The next expedition to the area was conducted in 1896 when Aubrey Woodward Newman attempted to lead a party overland f ...

Hamersley Range
The Hamersley Range is a mountainous region of the Pilbara region of Western Australia. The range was named on 12 June 1861 by explorer Francis Thomas Gregory after Edward Hamersley (senior), Edward Hamersley, a prominent promoter of his exploration expedition to the northwest. Juukan Gorge lies within the ranges, as does Karijini National Park (formerly known as Hamersley Range National Park). History The Aboriginal Australians, traditional Aboriginal owners of the area that the range runs through are the Kurrama people, Puutu Kunti Kurrama and Pinikura peoples. In 1999 a small range within the Hamersley was named the Hancock Range after the Hancock family, who were pioneers in the area. The Hancock range is east of Karijini National Park in a region of broad valleys and peaks that rise to almost . The Hancock Range is close to Mulga Downs Station, a property owned by the Hancock family and where Lang Hancock is buried. Geography The range runs from the Fortescue River in ...

Pilbara
The Pilbara () is a large, dry, thinly populated region in the north of Western Australia. It is known for its Aboriginal peoples; its ancient landscapes; the red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the ''Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). General The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,688 , and covers an area of .

Greek (language)
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy ( Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting im ...
