Ironwood
Ironwood is a common name for many woods or plants that have a reputation for hardness, or specifically a wood density that is heavier than water (approximately 1000 kg/m3, or 62 pounds per cubic foot), although usage of the name ironwood in English may or may not indicate a tree that yields such heavy wood. Some of the species with their common name * ''Acacia aulacocarpa'' (Brush ironwood) * ''Acacia estrophiolata'' (Southern ironwood), central Australia * ''Acacia excelsa'' (Ironwood) * '' Acacia melanoxylon'' (Ironwood) * ''Acacia stenophylla'' (Ironwood), Australia * ''Aegiphila martinicensis'' (Ironwood) * ''Afzelia africana'' (Ironwood) * ''Androstachys johnsonii'' (Lebombo ironwood), southeastern Africa and Madagascar * ''Allagoptera caudescens'', ''Borassus flabellifer'', '' Caryota urens'', ''Iriartea deltoidea'' Black Palm, Palmira wood (Black ironwood) * ''Argania spinosa'' (Morocco ironwood, Thorny, Prickly ironwood) * ''Astronium fraxinifolium'', ''Astronium ...

Acacia Estrophiolata
''Acacia estrophiolata'', commonly known as ironwood, southern ironwood, desert ironwood or utjanypa, is a tree native to Central Australia. Description It is a graceful, pendulous shade tree, which grows from about tall and has a trunk with a diameter of up to about 0.45 m. It has a spreading crown that becomes weeping as the tree matures. Young plants have rigid branches and short straight phyllodes that appear in clusters as trees mature the branches become pendulous and the light green spiky phyllodes in crease in length but are no longer clustered. It has a heavy bloom of spherical pale yellow flowers after winter rains. The tree has a slow growth rate and is both drought and frost tolerant. Taxonomy The species was first formally described by botanist Ferdinand von Mueller in 1882 as part of the work ''Definitions of some new Australian plants'' as published in ''Southern Science Record''. It was reclassified as ''Racosperma estrophiolatum'' by Leslie Pedley in 1987 then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Excelsa
''Acacia excelsa'', also known as ironwood, rosewood, bunkerman and doodlallie is a tree of the genus ''Acacia'' and the subgenus ''Plurinerves'' that is endemic to inland parts of north-eastern Australia.

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

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 ...

Backhousia Subargentea
''Backhousia subargentea'' (syn. ''Choricarpia subargentea'') is a rare Australian rainforest tree, growing near Mullumbimby in north eastern New South Wales and from Boonah to Imbil in south eastern Queensland. Common names include giant ironwood, ironwood box, scrub ironwood and lancewood. The New South Wales habitat of ''Backhousia subargentea'' is dry rainforest thickets on hillsides near Mullumbimby. It grows in association with the shatterwood and wild quince. Description ''Backhousia subargentea'' is a small tree to medium tree, occasionally reaching 30 metres in height. However, it is much smaller in New South Wales, reaching only 8 metres high and with a stem diameter of 20 cm. The trunk is often multi-stemmed and crooked, not cylindrical in cross section with some buttressing at the base. The trunk can be smooth and glossy, of an attractive orange/brown or pinkish/mauve colour, or green where bark has recently been shed. Other times, the bark sheds irregu ...

Allocasuarina Torulosa
''Allocasuarina torulosa'', the rose she-oak or forest oak, is a tree which grows in sub-rainforest (just outside the main forest area) of Queensland and New South Wales, Australia. There, it is typically found on coastal footslopes, hills, and plains. Originally described as ''Casuarina torulosa'' by William Aiton, it was moved to its current genus in 1982 by Australian botanist Lawrie Johnson. It is the type species of the genus ''Allocasuarina''. ''A. torulosa'' is an evergreen tree that typically reaches 12-18 metres (40-60 feet) tall and 4.5-7.5 metres (15-25 feet) wide. It appears to have needle-like leaves, but these are actually twigs; the real leaves are actually in the joint of the needles and appear in whorls of four. These needles have a weeping, pendulous appearance, and turn reddish-brown in the winter. The tree produces warty cones 15-33 millimeters long and 15-15 millimeters in diameter. Its bark is thick and corky. The timber is reddish pink to brown. It is pri ... [...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] |
Allocasuarina Luehmannii
''Allocasuarina luehmannii'' (buloke or bull-oak) is a species of ironwood tree native to Australia and its wood is the hardest commercially available as measured by the 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 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, Australian buloke ranks at #21 overall on the poster World ...
