Acacia Chrysocephala
''Acacia chrysocephala'' is a shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae''. Description The dense, compact and spiny shrub typically grows to a height of . It blooms from May to October and produces yellow flowers. The inequilateral phyllodes have an obtriangular to shallowly obtriangular shape with a margin congruent with branchlet. The glabrous phyllodes are in length and and are commonly pungent. The simple inflorescences usually occur with one per axil forming globular flower heads with two to four flowers per head. Following flowering shallowly curved seed pods form with a length of up to and a width of . The shiny brown longitudinally oblong seeds are long. Taxonomy The species was first formally described by the botanist Bruce Maslin in 1978 as part of the work ''Studies in the genus Acacia (Mimosaceae) - A revision of the Uninerves - Triangulares, in part (the tetramerous species)'' as published in the journal '' Nuytsia''.

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.

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] |
Eucalyptus Marginata
''Eucalyptus marginata'', commonly known as jarrah, djarraly in Noongar language and historically as Swan River mahogany, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a tree with rough, fibrous bark, leaves with a distinct midvein, white flowers and relatively large, more or less spherical fruit. Its hard, dense timber is insect resistant although the tree is susceptible to dieback. The timber has been utilised for cabinet-making, flooring and railway sleepers. Description Jarrah is a tree which sometimes grows to a height of up to with a diameter at breast height (DBH) of , but more usually with a DBH of up to . Less commonly it can be a small mallee to 3 m. Older specimens have a lignotuber and roots that extend down as far as . It is a stringybark with rough, greyish-brown, vertically grooved, fibrous bark which sheds in long flat strips. The leaves are arranged alternately along the branches, narrow lance-s ...

Eucalyptus Wandoo
''Eucalyptus wandoo'', commonly known as wandoo, dooto, warrnt or wornt, is a small to medium-sized tree that is endemic to the southwest of Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of nine to seventeen, white flowers and conical to cylindrical fruit. It is one of a number of similar ''Eucalyptus'' species known as ''wandoo''. Description ''Eucalyptus wandoo'' is a tree that typically grows to a height of and sometimes to and has a diameter of and where the bole or trunk that is usually straight and composes 50% to 65% of the total height of the tree. ''E.wandoo'' can have long lifetimes with some trees is excess of 150 years of age. It forms a lignotuber, the woody tuber that begins to develop near the base of seedlings but can become huge in older trees and contains embedded epicormic buds that allow the plant to regenerate following destruction of the crown following fire or drought.

Scaddan, Western Australia
Scaddan is a small town in Western Australia located east of Perth situated just off the Coolgardie-Esperance Highway between Norseman and Esperance in the Goldfields-Esperance region of Western Australia. The area was originally known as Thirty Mile, because of its distance from Esperance. The British settled the area before 1914 and were commonly using the name Scaddan at around that time. The name of the post office was changed from Thirty Mile to Scaddan in 1915 and by 1916 a school and hall had been built in the town. The government delayed declaring the town until the route of the Norseman-Esperance railway was settled. The townsite was finally gazetted in 1924.''Western Australian Government Gazette'', file 2007/14, 15 February 1924, p.275. The town is named after John "Happy Jack" Scaddan, the premier Premier is a title for the head of government in central governments, state governments and local governments of some countries.

Stirling Range
The Stirling Range or Koikyennuruff is a range of mountains and hills in the Great Southern region of Western Australia, south-east of Perth. It is over wide from west to east, stretching from the highway between Mount Barker and Cranbrook eastward past Gnowangerup. The Stirling Range is protected by the Stirling Range National Park, which was gazetted in 1913, and has an area of . Environment Geology The mountains are formed of metamorphic rock derived from quartz sandstones and shales deposited during the Paleoproterozoic Era, between 2,016 and 1,215 million years ago (based on U-Th-Pb isotope geochronology of monazite crystals). The sediments were subsequently metamorphosed 1,215 million years ago, and later folded during reactivation of basement structures recording lateral displacements between Antarctica and Australia. Despite the relative youth of the mountains, the soils remain very poor, creating the species-rich heathland flora. Climate As the only ver ...

York, Western Australia
York is the oldest inland town in Western Australia, situated on the Avon River, east of Perth in the Wheatbelt, on Ballardong Nyoongar land,King, A and Parker, E: York, Western Australia's first inland town, Parker Print, 2003 p.3. and is the seat of the Shire of York. The name of the region was suggested by JS Clarkson during an expedition in October 1830 because of its similarity to his own county in England, Yorkshire.John E Deacon: A Survey of the Historical Development of the Avon Valley with Particular Reference to York, Western Australia During the Years 1830-1850, UWA, 1948. After thousands of years of occupation by Ballardong Nyoongar people, the area was first settled by Europeans in 1831, two years after Perth was settled in 1829. A town was established in 1835 with the release of town allotments and the first buildings were erected in 1836. The region was important throughout the 19th century for sheep and grain farming, sandalwood, cattle, goats, pigs and ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...
