Lagarostrobos
''Lagarostrobos franklinii'' is a species of conifer native to the wet southwestern corner of Tasmania, Australia. It is often known as the Huon pine or Macquarie pine, although it is actually a podocarp (Podocarpaceae), not a true pine (Pinaceae). It is the sole species in the genus ''Lagarostrobos''; one other species ''L. colensoi'' (endemic to New Zealand) formerly included has been transferred to a new genus ''Manoao''. The genus was also formerly included in a broader circumscription of the genus ''Dacrydium''. In molecular phylogenetic analyses ''Lagorostrobos'' was found to be related to '' Parasitaxus'' (a parasitic and monotypic genus from New Caledonia) and ''Manoao'', but their exact relationships are unresolved. The wood is highly prized for its golden yellow colour, fine grain, and natural oils that resist rotting. The chemical giving the timber its unique smell and preservative qualities is methyl eugenol. It has been planted in the grounds of Crathes Castle, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Superlative Trees
The world's superlative trees can be ranked by any factor. Records have been kept for trees with superlative height, trunk diameter or girth, canopy coverage, airspace volume, wood volume, estimated mass, and age. Tallest The heights of the tallest trees in the world have been the subject of considerable dispute and much exaggeration. Modern verified measurements with laser rangefinders or with tape drop measurements made by tree climbers (such as those carried out by canopy researchers), have shown that some older tree height measurement methods are often unreliable, sometimes producing exaggerations of 5% to 15% or more above the real height. Historical claims of trees growing to , and even , are now largely disregarded as unreliable, and attributed to human error. The following are the tallest reliably measured specimens from the top 10 species. This table shows only currently standing specimens: Tallest historically Despite the high heights attained by trees nowada ...

Podocarpaceae
Podocarpaceae is a large family of mainly Southern Hemisphere conifers, known in English as podocarps, comprising about 156 species of evergreen trees and shrubs.James E. Eckenwalder. 2009. ''Conifers of the World''. Portland, Oregon: Timber Press. . It contains 19 genera if ''Phyllocladus'' is included and ''Manoao'' and ''Sundacarpus'' are recognized. The family is a classic member of the Antarctic flora, with its main centres of diversity in Australasia, particularly New Caledonia, Tasmania, and New Zealand, and to a slightly lesser extent Malesia and South America (primarily in the Andes Mountains). Several genera extend north of the equator into Indochina and the Philippines. ''Podocarpus'' reaches as far north as southern Japan and southern China in Asia, and Mexico in the Americas, and ''Nageia'' into southern China and southern India. Two genera also occur in sub-Saharan Africa, the widespread ''Podocarpus'' and the endemic '' Afrocarpus''. ''Parasitaxus usta'' is uniqu ...

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 ...

Manoao
''Manoao'' is a monotypic genus in the family ''Podocarpaceae.'' The single species, ''M. colensoi'', known as manoao (Māori), silver pine, Westland pine, or white silver pine, is endemic to New Zealand. Before 1996 it was classified in genus ''Dacrydium'' or ''Lagarostrobos'', but has recently been recognised as a distinct genus; some botanists still treat it in ''Lagarostrobos'' on the basis that it is not phylogenetically distinct from that genus. In molecular phylogenetic analyses ''Manoao'' was found to be related to ''Parasitaxus'' (a parasitic and monotypic genus from New Caledonia) and ''Lagarostrobos'' (a single species from Tasmania when narrowly defined), but their exact relationships are unresolved. ''Manoao colensoi'' is a slow-growing evergreen tree up to in height, in shady, wet areas of New Zealand. It is a source of fine, straight and durable timber. Distribution ''M. colensoi'' can be found in the North Island from Te Paki southwards to Mt Ruapehu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parasitaxus
''Parasitaxus usta'' is a rare species of conifer of the family Podocarpaceae, and the sole species of the genus ''Parasitaxus''. It is a woody shrub up to 1.8 m found only in the remote, densely forested areas of New Caledonia, first discovered and described by Vieillard in 1861. It is generally mentioned that ''Parasitaxus usta'' is the only known parasitic gymnosperm. The species remarkably lacks roots and is always found attached to the roots of ''Falcatifolium taxoides'' (another member of the Podocarpaceae). However, the question is still left open, as the plant is in any case not a haustorial parasite, which is usually the case with angiosperms. Certain experts therefore consider the plant as a myco-heterotroph. Molecular phylogenetic analysis also suggest affinities between ''Parasitaxus'' and the genera ''Manoao'' (New Zealand) and ''Lagarostrobos'' (Tasmania). Parasitaxus has been shown to contain high levels of chlorophyll. However, a genome analysis shows that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dacrydium
''Dacrydium'' is a genus of conifers belonging to the podocarp family Podocarpaceae. Sixteen species of evergreen dioecious trees and shrubs are presently recognized. The genus was first described by Solander in 1786, and formerly included many more species, which were divided into sections A, B, and C by Florin in 1931. The revisions of de Laubenfels and Quinn (see references), reclassified the former section A as the new genus '' Falcatifolium'', divided Section C into new genera ''Lepidothamnus, Lagarostrobos'' and ''Halocarpus'', and retained Section B as genus ''Dacrydium''. Species Distribution The natural range of ''Dacrydium'' extends from New Zealand, New Caledonia, Fiji and the Solomon Islands through Malesia (New Guinea, Indonesia, Malaysia and the Philippines), to Thailand and southern China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Read (Tasmania)
Mount Read is a mountain located in the West Coast region of Tasmania, Australia, and is at the north west edge of the West Coast Range. With an elevation of above sea level, Mount Read has had as colourful a history, similar to that of Mount Lyell, with mines, settlements and other activities on its slopes for over a hundred years. Geology The main copper and gold ore bearing deposits in the West Coast Range are known to occur in the Mount Read Volcanics relating to the complex geology of the area. Mineralisation and deposits were being identified well beyond the life of the original mines utilised on Mount Read. To the south east of Mount Read are many features of glaciation in the Tyndall Range as well as glacial lakes of Lake Westwood, Lake Selina, and Lake Julia. Hercules Haulage The Hercules Mine on Mount Read was connected by a haulage incline to Williamsford and then to the North East Dundas Tramway. The haulage was self-acting and long and high with a maxi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Conifer Cone
A conifer cone (in formal botany, botanical usage: strobilus, plural strobili) is a seed-bearing organ on gymnosperm plants. It is usually woody, ovoid to globular, including scales and bracts arranged around a central axis, especially in conifers and cycads. The cone of Pinophyta (conifer clade) contains the plant sexuality, reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually herbaceous plant, herbaceous and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the cone (geometry), geometric cone. The individual plates of a cone are known as ''scales''. The ''umbo'' of a conifer cone refers to the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale. The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berry (botany)
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds. Many berries are edible, but others, such as the fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that bears berries is said to be bacciferous or baccate (a fruit that resembles a ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified him for ...
