Laysan Fan Palm

	Laysan Fan Palm The Laysan fan palm is a not formally described, extinct species of palm most likely in the genus ''Pritchardia''. Endemic to the island of Laysan, it had become extinct by 1896. History The palm was first accounted in 1828 by early visitors to Laysan island. Karl Izembek, surgeon of the Russian ship ''Moller'', was the first to write of the species. In 1859, there was an account of 5 mature individuals remaining. By the time Hugo Schauinsland visited in 1896, all the palms had been killed. He blamed human activity, citing evidence of palm wood in charcoal. He noticed many remaining stumps, alluding to a population of several hundred decades before. Evidence of the palms was last observed in 1914 as "decaying remains". Description The palms were known to be up to 15 feet tall. Schauinsland noticed stumps with a diameter up to 50 cm. He was told that the palms had huge fan-shaped leaves, long inflorescences, and long fruit racemes, leading to him identifying it as a ''Pritchard ...

picture info	Laysan Laysan (; haw, italics=no, Kauō ), located northwest of Honolulu at , is one of the Northwestern Hawaiian Islands. It comprises one land mass of , about in size. It is an atoll of sorts, although the land completely surrounds a shallow central lake some above sea level that has a salinity approximately three times greater than the ocean. Laysan's Hawaiian name, Kauō, means ''egg''. Geology Laysan is the second largest single landmass in the Northwestern Hawaiian Islands, after Sand Island at Midway Atoll. Laysan was created by coral growth and geologic upshift. The fringing reefs surrounding the island cover about . Lake Laysan, the , brown, hypersaline lake in the island's interior, has varied in depth over the decades. In the 1860s, the lake was at most deep, but by the 1920s it averaged deep, because of the buildup of sand that had been blown away in sandstorms. The best way to find fresh water on Laysan is to observe where the finches are drinking; the fresh wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Pritchardia The genus ''Pritchardia'' (family Arecaceae) consists of between 24 and 40 species of fan palms (subfamily Coryphoideae) found on tropical Pacific Ocean islands in Fiji, Samoa, Tonga, Tuamotus, and most diversely in Hawaii. The generic name honors William Thomas Pritchard (1829-1907), a British consul at Fiji. Description These palms vary in height, ranging from . The leaves are fan-shaped (''costapalmate'') and the trunk columnar, naked, smooth or fibrous, longitudinally grooved, and obscurely ringed by leaf scars. The flowers and subsequent fruit are borne in a terminal cluster with simple or compound branches of an arcuate or pendulous inflorescence that (in some species) is longer than the leaves. Species There are 29 known species, of which 19 are endemic to the Hawaiian Islands, with the remainder on other island groups. * '' Pritchardia affinis'' Becc. – Hawaii Pritchardia (Island of Hawaii) * '' Pritchardia arecina'' Becc. – Maui Pritchardia (Maui, Hawaii ...

	Hugo Schauinsland Hugo Hermann Schauinsland (30 May 1857 – 5 June 1937) was a German zoologist born in Rittergut Dedawe, Kreis Labiau, East Prussia. He studied natural sciences at the University of Geneva and zoology at the University of Königsberg, obtaining his doctorate in 1883. Following graduation he conducted research in Naples and Munich. In 1887 he became ''Gründungsdirektor'' (founding director) of the ''Städtischen Sammlungen für Naturgeschichte und Ethnographie'', later to be known as the Übersee-Museum Bremen. Schauinsland served as director of the museum until his retirement in 1933. (succeeded by Carl Friedrich Roewer, 1881–1963). Also found at In 1896–97 he conducted scientific research in the Pacific (including the Hawaiian Islands). The Hawaiian monk seal (''Monachus schauinslandi'') and the Redspotted sandperch (''Parapercis schauinslandii'') are named in his honour, as are a number of smaller creatures; ('' Pseudaneitea schauinslandi'', ''Maorichiton schauinslandi'' ...

picture info	Palynology Palynology is the "study of dust" (from grc-gre, παλύνω, palynō, "strew, sprinkle" and '' -logy'') or of "particles that are strewn". A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age. The condition and identification of those particles, organic and inorganic, give the palynologist clues to the life, environment, and energetic conditions that produced them. The term is commonly used to refer to a subset of the discipline, which is defined as "the study of microscopic objects of macromolecular organic composition (i.e., compounds of carbon, hydrogen, nitrogen and oxygen), not capable of dissolution in hydrochloric or hydrofluoric acids". It is the science that studies contemporary and fossil palynomorphs (paleopalynology), including pollen, spores, orbicules, dinocysts, acritarchs, chitinozoans and scolecodonts, together with particulate organic matter (POM) and kerogen found in sedimen ...

	Pritchardia Remota ''Pritchardia remota'', the Nihoa pritchardia, Nihoa fan palm, or Loulu, is a species of palm endemic on the island of Nihoa, Hawaii, and later transplanted to the island of Laysan. It is a smaller tree than most other species of ''Pritchardia'', typically reaching only tall and with a trunk diameter of . It is the only type of tree on the island and used to be abundant. In 1885 a wildfire ravaged the island, destroying most of the palms. Only about 700 of these trees remain, making the species endangered but numbers are slowly increasing. The palm is being cultivated in botanical gardens.United States Fish and Wildlife Service, pp. 3 Though it is impossible to mistake ''P. remota'' for any other species in its natural habitat, it can be discerned from other ''Pritchardia'' species by its wavy leaves, its short and hairless inflorescences, and its tiny, spherical fruits. A similar undescribed species existed on Laysan, the Laysan fan palm, but was made extinct after Laysan was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	George Campbell Munro George Campbell Munro (10 May 1866 – 4 December 1963) was a New Zealand born pioneer of Hawaiian botany and ornithology. He settled on a ranch in Lanai and wrote one of the first books on the birds of Hawaii, many species of which are now extinct. The plant genus ''Munroidendron'' and the extinct Lanai finch '' Dysmorodrepanis munroi'' are named after him. Munro was born in New Zealand, but little is known of his early life other than that he was a gumdigger collecting kauri tree resin for the varnish industry. He had also trained in taxidermy. He arrived in Honolulu on December 13, 1890 to assist Henry C. Palmer to collect bird specimens for the collection of Lord Walter Rothschild. He then worked on Kauai and Molokai managing a ranch until 1906 collaborating also with R.C.L. Perkins to study local fauna. After a brief visit to New Zealand in 1911 he returned to manage Dole Company’s Lana‘i Lanai ( haw, Lānai, , , also ,) is the sixth-largest of the Hawaiian Islands and ...

picture info	Extinct Flora Of Hawaii Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, mam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
