Buloke
''Allocasuarina luehmannii'' (buloke or bull-oak) is a species of casuarinaceae, ironwood tree native to Australia and its wood is the hardest commercially available as measured by the Janka hardness test, Janka Hardness Scale. Description The evergreen tree typically grows to a height of and usually produces a clear trunk. It is moderately to long-lived, usually over 15 years with a moderate growth rate. It is dioecious with male and female flowers on separate plants, which flowers in spring. It is cited as having the hardest wood in the world, with a Janka hardness test, Janka hardness of 22,500 N (5,060 lbf). HoweverThe Wood Databasegives it a Janka hardness of only 16,600 N (3,760 lbf):"Australian buloke is commonly reported as the hardest wood in the world. This is based upon a single data source and may not give the best representation of all testing and data available. Consequently, with as many data points taken into consideration as possible, Au ...

Shire Of Buloke
The Shire of Buloke is a local government area in Victoria, Australia, located in the western part of the state. It covers an area of and, in June 2018, had a population of 6,184. It includes the towns of Birchip, Charlton, Donald, Sea Lake and Wycheproof. It was formed in 1995 from the amalgamation of the Shire of Wycheproof, Shire of Birchip, Shire of Charlton, Shire of Donald, and parts of the Shire of Kara Kara. The Shire is governed and administered by the Buloke Shire Council; its seat of local government and administrative centre is located at the Council headquarters in Wycheproof, it also has service centres located in Birchip, Charlton, Donald and Sea Lake. The Shire is named after a major geographical feature in the region, Lake Buloke, which is located in the south of the LGA; the name also comes from the "buloke" or "bulloak" tree ''Allocasuarina luehmannii'', which is common in the region. Within the Shire, agriculture, particularly grain production, is the pred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casuarinaceae
The Casuarinaceae are a family of dicotyledonous flowering plants placed in the order Fagales, consisting of four genera and 91 species of trees and shrubs native to eastern Africa, Australia, Southeast Asia, Malesia, Papuasia, and the Pacific Islands. At one time, all species were placed in the genus ''Casuarina''. Lawrence Alexander Sidney Johnson separated out many of those species and renamed them into the new genera of ''Gymnostoma'' in 1980 and 1982, ''Allocasuarina'' in 1982, and ''Ceuthostoma'' in 1988, with some additional formal descriptions of new species in each other genus. At the time, it was somewhat controversial. The monophyly of these genera was later supported in a 2003 genetics study of the family. In the Wettstein system, this family was the only one placed in the order Verticillatae. Likewise, in the Engler, Cronquist, and Kubitzki systems, the Casuarinaceae were the only family placed in the order Casuarinales. Members of this family are characterized ...

Janka Hardness Test
The Janka hardness test (; ), created by Austrian-born American researcher Gabriel Janka (1864–1932), measures the resistance of a sample of wood to denting and wear. It measures the force required to embed an steel ball halfway into a sample of wood. (The diameter was chosen to produce a circle with an area of 100 square millimeters ne square centimeter) A common use of Janka hardness ratings is to determine whether a species is suitable for use as flooring. For hardwood flooring, the test usually requires a sample with a thickness of at least 6–8 mm, and the most commonly used test is the ASTM D1037. When testing wood in lumber form, the Janka test is always carried out on wood from the tree trunk (known as the heartwood), and the standard sample (according to ASTM D143) is at 12% moisture content and clear of knots. The hardness of wood varies with the direction of the wood grain. Testing on the surface of a plank, perpendicular to the grain, is said to be of "side h ...

William Aiton
William Aiton (17312 February 1793) was a Scotland, Scottish botanist. Aiton was born near Hamilton, Scotland, Hamilton. Having been regularly trained to the profession of a gardener, he travelled to London in 1754, and became assistant to Philip Miller, then superintendent of the Chelsea Physic Garden. In 1759 he was appointed director of the newly established Royal Botanic Gardens, Kew, botanical garden at Kew, where he remained until his death. He effected many improvements at the gardens, and in 1789 he published ''Hortus Kewensis'', a catalogue of the plants cultivated there. He is buried at nearby St. Anne's Church, Kew. A second and enlarged edition of the ''Hortus'' was brought out in 1810–1813 by his eldest son, William Townsend Aiton. Aiton is commemorated in the Specific epithet (botany), specific epithet ''aitonis''. In 1789, he classified the Sampaguita plant to the ''Jasmine, Jasminium'' genus and also named it as ''Arabian Jasmine'' because it was believed th ...

Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae ('' Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the ...

Flora Of Victoria (Australia)
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allocasuarina
''Allocasuarina'' is a genus of trees in the flowering plant family Casuarinaceae. They are endemic to Australia, occurring primarily in the south. Like the closely related genus ''Casuarina'', they are commonly called sheoaks or she-oaks. Wilson and Johnson distinguish the two very closely related genera, ''Casuarina'' and ''Allocasuarina'' on the basis of: *''Casuarina'': the mature samaras being grey or yellow-brown, and dull; cone bracteoles thinly woody, prominent, extending well beyond cone body, with no dorsal protuberance; *''Allocasuarina'': the mature samaras being red-brown to black, and shiny; cone bracteoles thickly woody and convex, mostly extending only slightly beyond cone body, and usually with a separate angular, divided or spiny dorsal protuberance. Description They are trees or shrubs that are notable for their long, segmented branchlets that function as leaves. Formally termed cladodes, these branchlets somewhat resemble pine needles, although sheoaks ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
