Acaena Antarctica
''Acaena antarctica'' is a small herbaceous plant in the Rosaceae family native to Argentina, Chile and the Falkland Islands. Taxonomy and naming ''Acaena antarctica'' was first formally described in 1846 by Joseph Dalton Hooker. Kew holds specimens collected by Hooker from Hermite Island, Cape Horn on the Ross expedition. The genus name ''Acaena'' is derived from the Ancient Greek word ''akaina'' meaning "thorn" or "spine", referring to the spiny calyx of many species of ''Acaena''. The specific epithet, ''antarctica'', derives from the Greek (''anti'', "opposite" and ''arktos'', "bear") and designates the place opposite the constellations of the Great and the Little Bear, thus describing the species as coming from south of the South Pole circle.

Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified him for ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Flora Of Argentina
The Environment of Argentina is characterised by high biodiversity. Biodiversity Subtropical plants dominate the Gran Chaco in the north, with the ''Dalbergia'' genus of trees well represented by Brazilian rosewood and the quebracho tree; also predominant the wacho white and black algarrobo trees ('' Prosopis alba'' and ''Prosopis nigra''). Savannah-like areas exist in the drier regions nearer the Andes. Aquatic plants thrive in the wetlands of Argentina. In central Argentina the ''humid pampas'' are a true tallgrass prairie ecosystem. The original pampa had virtually no trees; some imported species like the American sycamore or eucalyptus are present along roads or in towns and country estates (''estancias''). The only tree-like plant native to the pampa is the evergreen Ombú. The surface soils of the pampa are a deep black color, primarily mollisols, known commonly as ''humus''. This makes the region one of the most agriculturally productive on Earth; however, this is also res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Chile
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acaena
''Acaena'' is a genus of about 60 species of mainly evergreen, creeping herbaceous perennial plants and subshrubs in the family Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii ('' A. exigua'') and California ('' A. pinnatifida''). The leaves are alternate, long, and pinnate or nearly so, with 7–21 leaflets. The flowers are produced in a tight globose nflorescence in diameter, with no petals. The fruit is also a dense ball of many seeds; in many (but not all) species the seeds bear a barbed arrowhead point, the seedhead forming a burr which attaches itself to animal fur or feathers for dispersal. Several ''Acaena'' species in New Zealand are known by the common name bidibid. The word is written variously ''bidi-bidi'', ''biddy-biddy'', ''biddi-biddi'', ''biddi-bid'' and a number of other variations. These names are the English rendition of the ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Expedition
The Ross expedition was a voyage of scientific exploration of the Antarctic in 1839 to 1843, led by James Clark Ross, with two unusually strong warships, HMS ''Erebus'' and HMS ''Terror''. It explored what is now called the Ross Sea and discovered the Ross Ice Shelf. On the expedition, Ross discovered the Transantarctic Mountains and the volcanoes Erebus and Terror, named after his ships. The young botanist Joseph Dalton Hooker made his name on the expedition. The expedition inferred the position of the South Magnetic Pole, and made substantial observations of the zoology and botany of the region, resulting in a monograph on the zoology, and a series of four detailed monographs by Hooker on the botany, collectively called ''Flora Antarctica'' and published in parts between 1843 and 1859. The expedition was the last major voyage of exploration made wholly under sail. Among the expedition's biological discoveries was the Ross seal, a species confined to the pack ice of Antarcti ...

Friedrich August Georg Bitter
Friedrich August Georg Bitter (13 August 1873 – 30 July 1927) was a German botanist and lichenologist. Born in Bremen, he studied at the Universities of Jena, Munich and Kiel, earning his doctorate at the latter institution in 1896. Afterwards he performed assignments in Berlin. In his studies he was influenced by instructors such as Simon Schwendener (1829–1919), Friedrich Wilhelm Zopf (1846–1909) and Johannes Reinke (1849–1931). In 1905 he was named director of the botanical garden in Bremen. During the later part of his career he served as director of the botanical garden in Göttingen. He specialized in the botanical genus ''Solanum'', as evidenced by his ''Solana Africana'', a four-part monograph in which he provided descriptions of all known African ''Solanum'' species. In the field of lichenology, he conducted anatomical and developmental studies on the thallus of lichens. He performed significant research involving the lichen genus ''Parmelia'' (''Hypogymnia''). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
