Ironwood Tree
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 ...

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 ...

Backhousia Bancroftii
''Backhousia'' is a genus of thirteen currently known species of flowering plants in the family Myrtaceae. All the currently known species are endemic to Australia in the rainforests and seasonally dry forests of Queensland, New South Wales and Western Australia. In 1845 in the European science publication the ''Botanical Magazine'' William Jackson Hooker and William Henry Harvey first published this genus's formal description and name, after botanist James Backhouse from England and Australia. They grow to aromatic shrubs or trees from tall, with leaves long and wide, arranged opposite to each other. Species Sourced from the authoritative ''Australian Plant Name Index'' and ''Australian Plant Census'' . For taxa including undescribed species further afield outside Australia, for example likely in New Guinea, this list lacks them—refer also to the genus ''Kania''. * ''Backhousia angustifolia'' , curry myrtle, narrow leaf myrtle * ''Backhousia bancroftii'' , Johnstone Rive ...

Allocasuarina Verticillata
''Allocasuarina verticillata'', commonly known as drooping she-oak or drooping sheoak, is a nitrogen fixing native tree of southeastern Australia. Originally collected in Tasmania and described as ''Casuarina verticillata'' by French naturalist Jean-Baptiste Lamarck in 1786, it was moved to its current genus in 1982 by Australian botanist Lawrie Johnson. The 1889 book ''The Useful Native Plants of Australia'' records common names of the plant included "Shingle Oak," "Coast She-oak," " River Oak," " Salt-water Swamp Oak" and was called "Worgnal" by the Indigenous people of the Richmond and Clarence River areas of New South Wales. It also records that, "In cases of severe thirst, great relief may be obtained from chewing the foliage of this and other species, which, being of an acid nature, produces a flow of saliva—a fact well-known to bushmen who have traversed waterless portions of the country. This acid is closely allied to citric acid, and may prove identical with it. Childr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allocasuarina Inophloia
''Allocasuarina inophloia'', also known as woolly oak, or stringybark she-oak, is a shrub or small tree of the she-oak family Casuarinaceae endemic to inland New South Wales and Queensland. The hairy bark is an unusual feature. Taxonomy First collected near Roma in central Queensland, the stringybark she-oak was described by Ferdinand von Mueller and Frederick Manson Bailey in 1882 as ''Casuarina inophloia''. Exactly 100 years later, Lawrie Johnson moved it to its current genus ''Allocasuarina'' in his revision of the she-oaks. Description ''Allocasuarina inophloia'' grows as a small tree with an open habit ranging from high. It is dioecious. Like all she-oaks, its foliage is composed of segmented branchlets with segments known as articles, its leaves reduced to tiny scales between them. Distribution and habitat In New South Wales it occurs in areas such as the Clarence River valley, Emmaville, Yetman, south to Waralda, while it ranges in Queensland north to Herberton. It is ...

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 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 ...

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] |
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 ...
