Pōhutukawa
Pōhutukawa (''Metrosideros excelsa''), also known as the New Zealand Christmas tree, or iron tree, is a coastal evergreen tree in the Myrtus, myrtle family, Myrtaceae, that produces a brilliant display of red (or occasionally orange, yellow or white) flowers, each consisting of a mass of stamens. The pōhutukawa is one of twelve ''Metrosideros'' species Endemism, endemic to New Zealand. Renowned for its vibrant colour and its ability to survive even perched on rocky, precarious cliffs, it has found an important place in New Zealand culture for its strength and beauty, and is regarded as a chiefly tree (') by Māori people, Māori. Etymology The generic name ''Metrosideros'' derives from the Ancient Greek language, Ancient Greek ' or 'heartwood' and ' or 'iron'. The specific name (botany), species name ''excelsa'' is from Latin language, Latin ', 'highest, sublime'. ' is a Māori language, Māori word. Its closest equivalent in other Polynesian languages is the Cook Island Māo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Metrosideros
''Metrosideros'' is a genus of approximately 60 trees, shrubs, and vines in the family Myrtaceae, mostly found in the Pacific region. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek language, Ancient Greek ''metra'' or "heartwood" and ''sideron'' or "iron". Perhaps the best-known species are the pōhutukawa (''M. excelsa''), Metrosideros robusta, northern rātā (''M. robusta'') and Metrosideros umbellata, southern rātā (''M. umbellata'') of New Zealand, and ''Metrosideros polymorpha, ōhia lehua'' (''M. polymorpha'') from the Hawaiian Islands. Distribution ''Metrosideros'' is one of the most widely spread flowering plant genera in the Pacific. New Caledonia has 21 species, New Zealand has 12, New Guinea has seven and Hawaii has 5. The genus is present on most other high Pacific Islands, including Solomon Islands, Vanuatu, Fiji, Samoa, Cook Islands, French Polynesia, Bonin Island ...

Aerial Root
Aerial roots are Root, roots growing above the ground. They are often Plant development#Adventitious structures, adventitious, i.e. formed from nonroot tissue. They are found in diverse plant species, including epiphytes such as orchids (''Orchidaceae''), tropical coastal swamp trees such as mangroves, banyan figs (''Ficus subg. Urostigma''), the warm-temperate rainforest rata (''Metrosideros robusta''), and pōhutukawa trees of New Zealand (''Metrosideros excelsa''). Vines such as common ivy (''Hedera helix'') and poison ivy (''Toxicodendron radicans'') also have aerial roots. Types This plant organ that is found in so many diverse plant-families has different specializations that suit the plant-habitat. In general growth-form, they can be technically classed as ''gravitropism, negatively gravitropic'' (grows up and away from the ground) or ''positively gravitropic'' (grows down toward the ground). "Stranglers" (prop-root) Banyan trees are an example of a strangler fig th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Myrtaceae
Myrtaceae (), the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid ...

Eruera Maihi Patuone
Eruera Maihi Patuone ( – 19 September 1872) was a Māori people, Māori rangatira (chief), the son of the Ngāti Hao chief Tapua and his wife Te Kawehau. His exact birth year is not known, but it is estimated that he was at least 108 years old when he died. His younger brother was Tāmati Wāka Nene. With his father and brother, he was one of the first Māori people to have contact with Europeans when James Cook's ship visited in 1769. Name He was named Patuone at birth and acquired his longer name when he was baptised by Henry Williams (missionary), Archdeacon Henry Williams at Paihia on Sunday, 26 January 1840, a few days prior to the initial signing of the Treaty of Waitangi on 6 February. Eruera Maihi (Edward Marsh) was the name of Williams' spiritual mentor in England, and this name was also given to Williams' oldest son. Patuone's third wife was Takarangi, sister of Te Kupenga, a chief of Ngāti Paoa. Takarangi was baptised at the same time, adopting the name Riria (L ...

Genetic Drift
Genetic drift, also known as random genetic drift, allelic drift or the Wright effect, is the change in the Allele frequency, frequency of an existing gene variant (allele) in a population due to random chance. Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When few copies of an allele exist, the effect of genetic drift is more notable, and when many copies exist, the effect is less notable (due to the law of large numbers). In the middle of the 20th century, vigorous debates occurred over the relative importance of natural selection versus neutral processes, including genetic drift. Ronald Fisher, who explained natural selection using Mendelian inheritance, Mendelian genetics, held the view that genetic drift plays at most a minor role in evolution, and this remained the dominant view for several decades. In 1968, population geneticist Mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

In the United States and United Kingdom, he is best known as one of the leading British general officers in the American Revolutionary War, American War of Independence.
