Kauri
''Agathis'', commonly known as kauri or dammara, is a genus of evergreen coniferous trees, native to Australasia and Southeast Asia. It is one of three extant genera in the family Araucariaceae, alongside '' Wollemia'' and ''Araucaria'' (being more closely related to the former).de Laubenfels, David J. 1988. Coniferales. P. 337–453 in Flora Malesiana, Series I, Volume 10. Dordrecht: Kluwer Academic. Its leaves are much broader than most conifers. Kauri gum is commercially harvested from New Zealand kauri. Description Mature kauri trees have characteristically large trunks, with little or no branching below the crown. In contrast, young trees are normally conical in shape, forming a more rounded or irregularly shaped crown as they achieve maturity.Whitmore, T.C. 1977. ''A first look at Agathis''. Tropical Forestry Papers No. 11. University of Oxford Commonwealth Forestry Institute. The bark is smooth and light grey to grey-brown, usually peeling into irregular flakes t ...

New Zealand Kauri
''Agathis australis'', commonly known as kauri, is a species of coniferous tree in the family Araucariaceae, found north of 38°S in the northern regions of New Zealand's North Island. It is the largest (by volume) but not tallest species of tree in New Zealand, standing up to tall in the emergent layer above the forest's main canopy. The tree has smooth bark and small narrow leaves. Other common names to distinguish ''A. australis'' from other members of ''Agathis'' are southern kauri and New Zealand kauri. With its podsolization capability and regeneration pattern it can compete with faster growing angiosperms. Because it is such a conspicuous species, forest containing kauri is generally known as kauri forest, although kauri need not be the most abundant tree. In the warmer northern climate, kauri forests have a higher species richness than those found further south. Kauri even act as a foundation species that modify the soil under their canopy to create unique plant co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kauri Gum
Kauri gum is resin from kauri trees (''Agathis australis''), which historically had several important industrial uses. It can also be used to make crafts such as jewellery. Kauri forests once covered much of the North Island of New Zealand, before early settlers caused the forests to retreat, causing several areas to revert to weeds, scrubs, and swamps. Even afterwards, ancient kauri fields and the remaining forests continued to provide a source for the gum.Hayward, pp 4–5 Between 1820 and 1900, over 90% of Kauri forests were logged or burnt by Europeans. Kauri gum forms when resin from kauri trees leaks out through fractures or cracks in the bark, hardening upon exposure to air. Lumps commonly fall to the ground and can be covered with soil and forest litter, eventually fossilising. Other lumps form as branches forked or trees are damaged, releasing the resin.Hayward, p 2 Uses The Māori had many uses for the gum, which they called ''kapia''. Fresh gum was used as a typ ...

Agathis Robusta
''Agathis robusta'', commonly known as Queensland kauri (pine), kauri pine or smooth-barked kauri, is a coniferous tree in the family Araucariaceae. It has a disjunct distribution, occurring in Papua New Guinea and in two widely separated locations in Queensland, Australia. It was first described in 1859 and was heavily logged in the mid-19th century. It is not a true pine (family Pinaceae), but Araucariaceae and Pinaceae are both conifer families in the class Pinopsida. Description ''Agathis robusta'' is a large evergreen tree with a straight cylindrical trunk, which can often reach a height of , and occasionally . The trunk is usually about diameter at breast height (DBH), but occasionally may reach . The bark is orange-brown to grey-brown, smooth, but shedding in large flakes. The linear- elliptic leaves are up to long and wide, with numerous fine parallel veins and no midrib. They are carried on petioles measuring and are arranged in opposite pairs (rarely whorls of t ...

Araucariaceae
Araucariaceae is a Family (biology), family of conifers with three living Genus, genera, ''Araucaria'', ''Agathis'', and ''Wollemia''. While the family's native distribution is now largely confined to the Southern Hemisphere, except for a few species of ''Agathis'' in Malesia, it was formerly widespread in the Northern Hemisphere during the Jurassic and Cretaceous periods. Description Members of Araucariaceae are typically extremely tall evergreen trees, reaching heights of or more. They can also grow very large stem diameters; a New Zealand kauri tree (''Agathis australis'') named ''Tāne Mahuta'' ("The Lord of the Forest") has been measured at tall with a diameter at breast height of . Its total wood volume is calculated to be , making it the third-largest conifer after ''Sequoia sempervirens, Sequoia'' and ''Sequoiadendron'' (both from the Cupressaceae subfamily Sequoioideae). The trunks are columnar and have relatively large piths with resinous Cortex (botany), cortices. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Go Equipment
Go equipment refers to the board, stones (playing pieces), and bowls for the stones required to play the game of Go (game), Go. The quality and materials used in making Go equipment varies considerably, and the cost varies accordingly from economical to extremely expensive. History The oldest known surviving Go equipment is a board carved from rock that dates from the Han dynasty in China. Other examples of ancient equipment can be found in museums in Japan and Korea. Equipment Board The Go board, called the ''goban'' in Japanese language, Japanese, is the playing surface on which to place the stones. The standard board is marked with a 19×19 grid. Smaller boards include a 13×13 grid and a 9×9 grid used for shorter games that are often used to teach beginners. Some 19×19 boards have a 13×13 grid on the reverse side. 17×17 was used in historical times. Chinese boards are generally square; Japanese and Korean boards are slightly longer than wide, so that they for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Māori People
Māori () are the Indigenous peoples of Oceania, indigenous Polynesians, Polynesian people of mainland New Zealand. Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of Māori migration canoes, canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed Māori culture, a distinct culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori. Early contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi, Treaty of Waitangi/Te Tiriti o Waitangi in 1840, the two cultures coexisted for a generation. Rising ten ...

Patu
A patu is a club or pounder used by the Māori. The word in the Māori language means to strike, hit, beat, kill or subdue. Weapons These types of short-handled clubs were mainly used as a striking weapon. The blow administered with this weapon was a horizontal thrust straight from the shoulder at the enemy's temple. If the foe could be grasped by the hair then the patu would be driven up under the ribs or jaw. Patu were made from hardwood, whale bone, or stone. The most prestigious material for the patu was pounamu (greenstone). Māori decorated the patu by carving into the wood, bone or stone. Types of patu include: * '' patu pounamu'' or '' mere'': made from pounamu (greenstone). * ''patu onewa'': made of stone. These resemble the mere in outline but thicker, because the stone used was more easily broken than the resilient pounamu. * ''patu paraoa'': made of whale bone * ''patu tawaka'' and ''patuki'': made from wood. Other styles of short-handled wooden clubs include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karri
''Eucalyptus diversicolor'', commonly known as karri, is a species of flowering plant in the family Myrtaceae and is Endemism, endemic to the Southwest Australia, south-west of Western Australia. It is a tall tree with smooth light grey to cream-coloured, often mottled bark, lance-shaped adult leaves and barrel-shaped fruit. Found in higher rainfall areas, karri is commercially important for its timber. Description ''Eucalyptus diversicolor'' is the tallest tree that grows in Western Australia. It is a tall forest tree that typically grows to a height of but can reach as high as , making it the tallest tree in Western Australia and one of the tallest in the world. As of February 2019, the tallest known living karri is just over tall. A tree south of Pemberton, known as 'The Tyrant' is tall and in girth and contains approximately of wood in its trunk and is thought to be the largest karri by wood volume. A ''Eucalyptus diversicolor'' of height and of girth in Coimbra, Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barkcloth
Barkcloth or bark cloth is a versatile material that was once common in Asia, Africa, and the Pacific. Barkcloth comes primarily from trees of the family Moraceae, including '' Broussonetia papyrifera'', '' Artocarpus altilis'', '' Artocarpus tamaran'', and '' Ficus natalensis''. It is made by beating sodden strips of the fibrous inner bark of these trees into sheets, which are then finished into a variety of items. Many texts that mention "paper clothing" are actually referring to barkcloth. Some modern cotton-based fabrics are also named "barkcloth" for their resemblance to these traditional fabrics. Traditional Austronesia Before the development of woven textiles, barkcloth made from trees belonging to the mulberry family ( Moraceae) were an important aspect of the pre-Austronesian and Austronesian material culture during the Neolithic period. Stone barkcloth beaters, in particular, are considered part of the "Austronesian toolkit." They have been found in abundance i ...

Agathiphaga
''Agathiphaga'' is a genus of moths, known as kauri moths, and is the only living genus in the family Agathiphagidae. This caddisfly-like lineage of primitive moths was first reported by Lionel Jack Dumbleton in 1952, as a new genus of Micropterigidae. The caterpillars feed only on "kauri" (''Agathis'') and are currently considered the second most primitive living lineage of moths after Micropterigoidea. The larvae have been reported to be able to survive for 12 years in diapause, durability possibly a prerequisite to its possible dispersion around the Pacific islands in the seeds of ''Agathis''. Dumbleton described two species. '' Agathiphaga queenslandensis'' is found along the north-eastern coast of Queensland, Australia, and its larvae feed on ''Agathis robusta''. '' Agathiphaga vitiensis'' is found from Fiji to Vanuatu and the Solomon Islands, and its larvae feed on '' Agathis vitiensis''. A fossil member of Agathiphagidae, '' Agathiphagama,'' is known from the Burmese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lefipán Formation
The Lefipán Formation is a Maastrichtian to Danian, straddling the Cretaceous-Paleogene boundary, geologic Formation (geology), formation of the Cañadón Asfalto Basin in Chubut Province, Patagonia, Argentina. The up to thick stratigraphic unit comprises mudstones, sandstones, siltstones and conglomerate (geology), conglomerates, sourced from the North Patagonian Massif and deposited in a river delta, deltaic to shallow marine depositional environment, environment with a strong tide, tidal influence. The basin that in those times was connected to the widening Atlantic Ocean#South Atlantic, South Atlantic Ocean with a seaway connection to the Magallanes Basin, Austral Basin and possibly with the Pacific Ocean. The formation has provided unique fossil flora assemblages dating to the Cretaceous and Paleogene ages, and are characteristic of the early Cenozoic after the extinction of the dinosaurs. The occurrence of the same taxa in the Maastrichtian and Danian successions suggests t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
