Homalium Acuminatum
''Homalium acuminatum'', the Cook Islands homalium, is a species of tree in the willow family, Salicaceae. It is endemic to the Cook Islands, growing on the islands of Rarotonga, where it is known as ''mato'', and Mangaia, where it is known as ''moto''. It grows to a height of up to . On Rarotonga it dominates steep mountain slopes. The IUCN Red List calls it the Rarotonga homalium and considers it endemic Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsew ... to Rarotonga, though the Cook Islands Biodiversity Database lists it as also present, but "uncommon" on Mangaia.

Thomas Frederic Cheeseman
Thomas Frederick Cheeseman (8 June 184515 October 1923) was a New Zealand botanist. He was also a naturalist who had wide-ranging interests, such that he even described a few species of sea slugs (marine gastropod molluscs). Biography Cheeseman was born at Hull, in Yorkshire on 8 June 1845, the eldest of five children. He came to New Zealand at the age of eight with his parents on the ''Artemesia'', arriving in Auckland on 4 April 1854. He was educated at Parnell Grammar School and then at St John's College, Auckland. His father, the Rev. Thomas Cheeseman, had been a member of the old Auckland Provincial Council. Cheeseman started studying the flora of New Zealand, and in 1872 he published an accurate and comprehensive account of the plant life of the Waitākere Ranges. In 1874, he was appointed Secretary of the Auckland Institute and Curator of the Auckland Museum, which had only recently been founded. For the first three decades, Cheeseman was the only staff member who w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salicaceae
The Salicaceae is the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') included the willows, poplar, aspen, and cottonwoods. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the Scyphostegiaceae and many of the former Flacourtiaceae. In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera (''willow, Salix'', ''Populus'', and ''Chosenia''). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales. Under the new circumscription, all members of the family are trees or shrubs that have Simple leaf, simple leaves with Phyllotaxis, alternate arrangement and temperate members are usually deciduous. Most members have serrate or dentate leaf margins, and those that have such toothed margins all e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rarotonga
Rarotonga is the largest and most populous of the Cook Islands. The island is volcanic, with an area of , and is home to almost 75% of the country's population, with 13,007 of a total population of 17,434. The Cook Islands' Parliament buildings and Rarotonga International Airport, international airport are on Rarotonga. Rarotonga is a very popular tourist destination with many resorts, hotels and motels. The chief town, Avarua, on the north coast, is the capital of the Cook Islands. Captain John Dibbs, master of the colonial brig ''Endeavour'', is credited as the European discoverer on 25 July 1823, while transporting the missionary Reverend John Williams (missionary), John Williams. Geography Rarotonga is a kidney-shaped volcanic island, in circumference, and wide on its longest (east-west) axis. The island is the summit of an extinct Pliocene or Pleistocene volcano, which rises 5000 meters from the seafloor. The island was formed between 2.3 to 1.6 million years ago, with ...

Mangaia
Mangaia (traditionally known as A'ua'u Enua, which means ''terraced'') is the most southerly of the Cook Islands and the second largest, after Rarotonga. It is a roughly circular island, with an area of , from Rarotonga. Originally heavily populated, Mangaia's population has dropped by 75% in the last 50 years. Geography Originally known as ''A'ua'u'' or ''A'ua'u Enua'' ("terraced"), the island was named Mangaia (or ''Mangaianui-Neneva'', "Mangaia monstrously-great") by Tamaeu, who came to the island from Aitutaki in 1775. Geologists estimate the island is at least 18 million years old. It rises 4750 m (15,600 ft) above the ocean floor and has a land area of 51.8 km2. Surrounded by a fringing coral reef, like many of the southern Cook Islands, it is surrounded by a high ring of cliffs of fossil coral 60 m (200 ft) high, known as the makatea. The inner rim of the ''makatea'' forms a steep cliff, surrounding swamps and a central volcanic plateau. The interi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
