Pleurophyllum Speciosum
''Pleurophyllum speciosum'', also known as the giant emperor daisy or Campbell Island daisy, is a megaherb native to the Auckland and Campbell Islands of New Zealand. A false colour image is depicted on the lower left corner on the reverse of the current five dollar New Zealand banknote. The Campbell Island daisy was first described by Joseph Dalton Hooker in ''Flora Antarctica'' of 1844, after he had collected it during the Ross expedition. Conservation status In both 2009 and 2012 it was deemed to be "At Risk - Naturally Uncommon" under the New Zealand Threat Classification System The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand. The system was developed because the IUCN Red List, a similar conservation status system, had some ..., and this New Zealand classification was reaffirmed in 2018 (due to its restricted range).

Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved or indented, such that it can be used to grab onto, connect, or otherwise attach itself onto another object. In a number of uses, one end of the hook is pointed, so that this end can pierce another material, which is then held by the curved or indented portion. Some kinds of hooks, particularly fish hooks, also have a barb, a backwards-pointed projection near the pointed end of the hook to ensure that once the hook is embedded in its target, it can not easily be removed. Variations * Bagging hook, a large sickle or reaping hook used for harvesting grain * Bondage hook, used in sexual bondage play * Cabin hook, a hooked bar that engages into an eye screw, used on doors * Cap hook, hat ornament of the 15th and 16th centuries * Cargo hook (helicopter), different types of hook systems for helicopters * Crochet hook, used for crocheting thread or yarn * Drapery hook, for ha ...

Megaherb
Megaherbs are a group of herbaceous wildflowers growing in the New Zealand subantarctic islands and on the other subantarctic islands. They are characterised by their great size, with huge leaves and very large and often unusually coloured flowers, which have evolved as an adaptation to the harsh weather conditions on the islands. They suffer from overgrazing due to introduced mammals. Appearance and occurrence Originally, the term was coined to describe large-leaved herbs that form meadows in the subantarctic islands but has also been applied to describe tropical alpine vegetation forms found in the Andes, East Africa and New Guinea. They are large herbs that can reach dimensions of over one metre, often feature strikingly colourful flowers, large leaves and long stalks, and are important components of the ecosystems of the subantarctic islands. Beyond these traits, megaherbs can have different forms; for example, some genera have perennial leaves and others are deciduous. Int ...

Auckland Island
Auckland Island ( mi, Mauka Huka) is the main island of the eponymous uninhabited archipelago in the Pacific Ocean. It is part of the New Zealand subantarctic area. It is inscribed in the UNESCO World Heritage list together with the other New Zealand Subantarctic Islands in the region. Geography The island has a land area of about , and is long. It was formed 25 to 10 million years ago from a huge volcanic pile which formed two domes – one centred around Carnley Harbour in the south and another (the Ross Dome) around Disappointment Island to the west. The island is made of volcanic scoria, blanketed in over 2m of peat. It is notable for its steep cliffs and rugged terrain, which rises to over . Prominent peaks include Cavern Peak, at ; Mount Raynal, at ; Mount D'Urville, at ; Mount Easton, at ; and the Tower of Babel, at . The southern end of the island broadens to a width of , encompassing Carnley Harbour. At the western side a very narrow channel known as Victoria Pas ...

Campbell Islands
The Campbell Islands (or Campbell Island Group) are a group of subantarctic islands, belonging to New Zealand. They lie about 600 km south of Stewart Island. The islands have a total area of , consisting of one big island, Campbell Island (), and several small islets, notably Dent Island (), Isle de Jeanette Marie (), Folly Island (or Folly Islands), Jacquemart Island (), and Monowai Island (also known as Lion Rock, ). Ecologically, they are part of the Antipodes Subantarctic Islands tundra ecoregion. The islands are one of five subantarctic island groups collectively designated as a World Heritage Site by UNESCO. Geography * Campbell Island / Motu Ihupuku () * Dent Island () * Jacquemart Island () * Folly Island or Folly Islands The islands are relatively flat; due to tectonic pressure, however, there are mountains in the centre of each island. A sea stack at the southern tip of Jacquemart Island is – with the exception of the country's Antarctic claims – New Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

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 ...

Ross Expedition
The Ross expedition was a voyage of scientific exploration of the Antarctic in 1839 to 1843, led by James Clark Ross, with two unusually strong warships, HMS ''Erebus'' and HMS ''Terror''. It explored what is now called the Ross Sea and discovered the Ross Ice Shelf. On the expedition, Ross discovered the Transantarctic Mountains and the volcanoes Erebus and Terror, named after his ships. The young botanist Joseph Dalton Hooker made his name on the expedition. The expedition inferred the position of the South Magnetic Pole, and made substantial observations of the zoology and botany of the region, resulting in a monograph on the zoology, and a series of four detailed monographs by Hooker on the botany, collectively called ''Flora Antarctica'' and published in parts between 1843 and 1859. The expedition was the last major voyage of exploration made wholly under sail. Among the expedition's biological discoveries was the Ross seal, a species confined to the pack ice of Antarcti ...

New Zealand Threat Classification System
The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand. The system was developed because the IUCN Red List, a similar conservation status system, had some shortcomings for the unique requirements of conservation ranking in New Zealand. plants, animals, and fungi are evaluated, though the lattermost has yet to be published. Algae were assessed in 2005 but not reassessed since. Other protists have not been evaluated. Categories Species that are ranked are assigned categories: ;Threatened This category has three major divisions: ::*Nationally Critical - equivalent to the IUCN category of Critically endangered ::*Nationally Endangered - equivalent to the IUCN category of Endangered ::*Nationally Vulnerable - equivalent to the IUCN category of Vulnerable ;At Risk This has four categories: ::*Declining ::*Recovering ::*Relict ::*Naturally Uncommon ;Other categories ;;Introduced and Natur ...

Flora Of New Zealand
This article relates to the flora of New Zealand, especially indigenous strains. New Zealand's geographical isolation has meant the country has developed a unique variety of native flora. However, human migration has led to the importation of many other plants (generally referred to as 'exotics' in New Zealand) as well as widespread damage to the indigenous flora, especially after the advent of European colonisation, due to the combined efforts of farmers and specialised societies dedicated to importing European plants & animals. Characteristics Indigenous New Zealand flora generally has the following characteristics: * the majority are evergreen. * few annual herbs. * few cold-tolerant trees. * majority are dispersed by birds. * very few have defences against mammalian browsers. * few nitrogen fixing plants. * few fire-adapted species. * many dioecious species. * flowers are typically small and white. * many plants have divaricating growth forms. * many plants have evolved in ...

Flora Of The Campbell Islands
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
