Jarrah (tree)
''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 ...

James Donn
James Donn (1758–1813) was an English botanist and gardener. He was trained by William Aiton, a protege of Sir Joseph Banks and was Curator of the Cambridge University Botanic Garden, Cambridge, from 1790 until his death. His most important work was '' Hortus Cantabrigiensis'', first published in 1796 but with several later, much expanded, editions. It carried on past his death until 1845. A copy was given to the Library of the Gray Herbarium of Harvard University in 1895. He became a Fellow of the Linnean Society in 1812. A memorial to James Donn, exists on St Edward the Martyr's church in Cambridge. A grandson was the English composer William Sterndale Bennett Sir William Sterndale Bennett (13 April 18161 February 1875) was an English composer, pianist, conductor and music educator. At the age of ten Bennett was admitted to the London Royal Academy of Music (RAM), where he remained for ten years. B ....Sterndale Bennett, JR "The Life of Sterndale Bennett" pp5&46. ...

Stringybark
A stringybark can be any of the many ''Eucalyptus'' species which have thick, fibrous bark. Like all eucalypts, stringybarks belong to the family Myrtaceae. In exceptionally fertile locations some stringybark species (in particular messmate stringybark (''Eucalyptus obliqua'') can be very large, reaching over 80 metres in height. More typically, stringybarks are medium-sized trees in the 10 to 40 metre range. Early European colonists often used the bark for roofing and walls of huts. The term ''stringybark'' is a descriptive, vernacular name and does not imply any special taxonomic relationship within the genus ''Eucalyptus''. For example, scientists consider ''Eucalyptus obliqua'' to not be closely related to the other stringybarks, because of the gumnut shape. And ''Eucalyptus acmenoides'' is part of the ''mahogany'' group of eucalyptus. Also as the gumnuts are a different shape, despite the bark being somewhat stringy.Forest Trees of Australia, D.J.

Mooliabeenee, Western Australia
Mooliabeenee (also found misspelt as Mooliabeenie) is a locality in Western Australia, east of Gingin, within the Shire of Chittering. The nearby Mooliabeenie station lies on the Millendon Junction (near Midland) to Dongara section of the railway line now managed by Arc Infrastructure. It was originally built in 1894 as part of the Midland Railway. Also nearby is a disused long airstrip which was used by the United States Army Air Corps during World War II and associated with the Caversham Airfield at Middle Swan. Like the Caversham Airfield, the Mooliabeenee Airfield was later used as a motor racing track. Local car clubs regularly use the site for motorkhana {{Refimprove, date=August 2008 Motorkhana is a low-cost form of motorsport, unique to Australia and New Zealand but similar to autotesting in the UK and Ireland and gymkhana in the US.

Contour Line
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x,y) parallel to the (x,y)-plane. More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines. The gradient of the function is always perpendicular to the contour lines. When the lines are close together the magnitude of the grad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etymology
Etymology ()The New Oxford Dictionary of English (1998) – p. 633 "Etymology /ˌɛtɪˈmɒlədʒi/ the study of the class in words and the way their meanings have changed throughout time". is the study of the history of the Phonological change, form of words and, by extension, the origin and evolution of their semantic meaning across time. It is a subfield of historical linguistics, and draws upon comparative semantics, Morphology_(linguistics), morphology, semiotics, and phonetics. For languages with a long recorded history, written history, etymologists make use of texts, and texts about the language, to gather knowledge about how words were used during earlier periods, how they developed in Semantics, meaning and Phonological change, form, or when and how they Loanword, entered the language. Etymologists also apply the methods of comparative linguistics to reconstruct information about forms that are too old for any direct information to be available. By analyzing related ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Pilularis
''Eucalyptus pilularis'', commonly known as blackbutt, is a species of medium-sized to tall tree that is endemic to eastern Australia. It has rough, finely fibrous greyish bark on the lower half of the trunk, smooth white, grey or cream-coloured bark above, lance-shaped to curved adult leaves, flower buds in groups of between seven and fifteen, white flowers and hemispherical or shortened spherical fruit. Description ''Eucalyptus pilularis'' is a tree that typically grows to a height of but does not form a lignotuber. It has finely fibrous, greyish brown bark on the lower half of the trunk, white to grey or cream-coloured bark above, often with insect scribbles. Young plants have stems that are more or less square in cross-section and leaves that are dull green, paler on the lower surface, sessile and mostly arranged in opposite pairs. The juvenile leaves are lance-shaped, long and wide. Adult leaves are arranged alternately, more or less the same shade of glossy green on bot ...

Eucalyptus Robusta
''Eucalyptus robusta'', commonly known as swamp mahogany or swamp messmate, is a tree native to eastern Australia. Growing in swampy or waterlogged soils, it is up to high with thick spongy reddish brown bark and dark green broad leaves, which help form a dense canopy. The white to cream flowers appear in autumn and winter. The leaves are commonly eaten by insects, and are a food item for the koala. It is an important autumn-winter flowering species in eastern Australia, and has been planted extensively in many countries around the world. Its timber is used for firewood and in general construction. Description ''Eucalyptus robusta'' grows commonly as a straight, upright tree to around tall, with a trunk up to in diameter at breast height (dbh). The trunk and branches are covered with thick red-brown bark, which has a spongy feel and is stringy—peeling in longitudinal strips. The long irregular branches spread laterally, and form a dense canopy with the broad green leaves. Arr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Jackson
Port Jackson, consisting of the waters of Sydney Harbour, Middle Harbour, North Harbour and the Lane Cove and Parramatta Rivers, is the ria or natural harbour of Sydney, New South Wales, Australia. The harbour is an inlet of the Tasman Sea (part of the South Pacific Ocean). It is the location of the Sydney Opera House and Sydney Harbour Bridge. The location of the first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney. Port Jackson, in the early days of the colony, was also used as a shorthand for Sydney and its environs. Thus, many botanists, see, e.g, Robert Brown's ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', described their specimens as having been collected at Port Jackson. Many recreational events are based on or around the harbour itself, particularly Sydney New Year's Eve celebrations. The harbour is also the starting point of the Sydney to Hobart Yacht ...

Linnean Society Of London
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
