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 only 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 foun ... 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salicaceae
The Salicaceae are the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') includes the willows, poplars. 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 tropical 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'' (now a synonym of ''Salix''). 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, most 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 many of those that have s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Cook Islands
The Cook Islands is an island country in Polynesia, part of Oceania in the South Pacific Ocean. It consists of 15 islands whose total land area is approximately . The Cook Islands' Exclusive Economic Zone (EEZ) covers of ocean. Avarua is its capital. The Cook Islands is self-governing while in free association with New Zealand. Since the start of the 21st century, the Cook Islands conducts its own independent foreign and defence policy, and also has its own customs regulations. Like most members of the Pacific Islands Forum, it has no armed forces, but the Cook Islands Police Service owns a Guardian Class Patrol Boat, , provided by Australia, in order to police its waters. In recent decades, the Cook Islands have adopted an increasingly assertive and distinct foreign policy, and a Cook Islander, Henry Puna, served as Secretary General of the Pacific Islands Forum from 2021 to 2024. Most Cook Islanders are also citizens of New Zealand, but they also have the status of Coo ... [...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 10,898 of a total population of 15,040. The Parliament of the Cook Islands, Cook Islands' Parliament buildings and Rarotonga International Airport, international airport are on Rarotonga. Rarotonga is a 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 from the seafloor. The island was formed between 2.3 to 1.6 million ...

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, mainly due to the decline of the pineapple industry in the 1980s and a subsequent economic crisis in 1996. 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 4,750 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 in ...

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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...
