Lebronnecia
''Lebronnecia'' is a monotypic genus of flowering plants in the family Malvaceae. The sole species is ''Lebronnecia kokioides'', a very rare flowering shrub. Distribution Only a few hundred specimens are known to exist. The plant was first described in 1966, after a single tree with a few seedlings was discovered on Tahuata, an island in the Marquesas group of French Polynesia that had been severely deforested by livestock: cattle, goats, horses, and pigs. Further specimens were later found on the nearby island of Mohotani, uninhabited by humans, but similarly deforested by sheep, who seem to avoid eating the plant. It is now being cultivated in Hawaii Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland.

Gossypieae
Gossypieae is a tribe of the flowering plant subfamily Malvoideae. It includes the cotton ('' Gossypium'') and related plants. It is distinguished from the Hibisceae on the basis of embryo structure and its apparently unique possession of glands able to synthesize the pigment gossypol. Genera The following genera are recognised.

Francis Raymond Fosberg
Francis Raymond Fosberg (20 May 1908 – 25 September 1993) was an American botanist. A prolific collector and author, he played a significant role in the development of coral reef and island studies. History Ray Fosberg was born in Spokane, Washington but grew up in Turlock, California. He received a B.A. in Botany at Pomona College in 1930. Fosberg worked as a plant researcher at the Los Angeles County Museum, specializing in plants from islands on the coast of California and of the desert Southwest. He became interested in island ecosystems, and in 1932 moved to Honolulu to work at the University of Hawaii as an assistant to Harold St. John. There he received an invitation to participate in the Mangarevan Expedition led by the malacologist Charles Montague Cooke, Jr. The expedition visited 25 high islands and 31 coral islands, and Fosberg and St. John brought back 15,000 plant specimens. Fosberg received his M.S. in Botany from the University of Hawaii in 1937 and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malvaceae
Malvaceae (), or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include Theobroma cacao, cacao, Cola (plant), cola, cotton, okra, Hibiscus sabdariffa, roselle and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The genera with the largest numbers of species include ''Hibiscus'' (434 species), ''Pavonia (plant), Pavonia'' (291 species), ''Sida (plant), Sida'' (275 species), ''Ayenia'' (216 species), ''Dombeya'' (197 species), and ''Sterculia'' (181 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae ''sensu stricto'' comprise a very homogeneous and cladistically Monophyly, monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies ha ...

Tahuata
Tahuata is the smallest of the inhabited Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. It is located 4 km (2.5 mi.) to the south of the western end of Hiva Oa, across the Canal du Bordelais, called Ha‘ava in Marquesan. History Archaeological evidence indicates that Tahuata was inhabited by Polynesians as early as AD 200. In later pre-European times, the tribes of Tahuata were allied with the tribes from the Nuku province of Hiva Oa, and the island was considered a dependency of that province. The first recorded sighting by Europeans was by the Spanish expedition of Álvaro de Mandaña on 22 July 1595. They charted the island as ''Santa Cristina''. They landed at Vaitahu that they named ''Madre de Dios'' (God's Mother in Spanish). According to the Spanish accounts Tahuata had fowls, fish, sugar cane, plantains, nuts and fruits. The existent town was built on two sides of a rectangular space, the houses being of tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marquesas
The Marquesas Islands ( ; or ' or ' ; Marquesan: ' ( North Marquesan) and ' ( South Marquesan), both meaning "the land of men") are a group of volcanic islands in French Polynesia, an overseas collectivity of France in the southern Pacific Ocean. Their highest point is the peak of Mount Oave () on Ua Pou island, at 1,230 m (4,035 ft) above sea level. Archaeological research suggests the islands were colonized in the 10th century AD by voyagers from West Polynesia. Over the centuries that followed, the islands have maintained a "remarkably uniform culture, biology and language". The Marquesas were named after the 16th-century Spanish Viceroy of Peru, the Marquis of Cañete (), by navigator , who visited them in 1595. The Marquesas Islands constitute one of the five administrative divisions (') of French Polynesia. The capital of the Marquesas Islands' administrative subdivision is the town of Taioha'e, on the island of Nuku Hiva. The population of the Marque ...

French Polynesia
French Polynesia ( ; ; ) is an overseas collectivity of France and its sole #Governance, overseas country. It comprises 121 geographically dispersed islands and atolls stretching over more than in the Pacific Ocean, South Pacific Ocean. The total land area of French Polynesia is , with a population of 278,786 (Aug. 2022 census) of which at least 205,000 live in the Society Islands and the remaining population lives in the rest of the archipelago. French Polynesia is divided into five island groups: the Austral Islands; the Gambier Islands; the Marquesas Islands; the Society Islands (comprising the Leeward Islands (Society Islands), Leeward and Windward Islands (Society Islands), Windward Islands); and the Tuamotus. Among its 121 islands and atolls, 75 were inhabited at the 2017 census.

Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland.

Monotypic Malvales Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Endemic Flora Of The Marquesas Islands
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 becoming ...
