South Georgia Island
South Georgia ( es, Isla San Pedro) is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around long and has a maximum width of . The terrain is mountainous, with the central ridge rising to at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours. Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken.

Callitriche Antarctica
''Callitriche antarctica'', commonly known as the Antarctic water-starwort, is a small, prostrate plant with tiny yellow flowers in the family Plantaginaceae (though sometimes placed in its own family – Callitrichaceae).

Uncinia Macrolepis
''Uncinia'' is a genus of flowering plants in the family Cyperaceae, known as hook-sedges in Australia and as hook grasses or bastard grasses in New Zealand. The genus is characterised by the presence of a long hook formed by an extension of the rachilla, which is used to attach the fruit to passing animals (epizoochory), especially birds, and it is this feature which gives the genus its name, from the Latin ''uncinus'', meaning a hook or barb. Systematics ''Uncinia'' is a "satellite genus" of the very large genus '' Carex'', alongside other satellites such as ''Cymophyllus'', '' Kobresia'', ''Schoenoxiphium'', ''Vesicarex''. ''Uncinia'' seems to form a monophyletic group, with the most distinct species being '' U. kingii'', a species which has sometimes been placed in the genus ''Carex''. Similarly, ''Carex microglochin'' has sometimes been included in ''Uncinia'', as ''U. microglochin''. Distribution ''Uncinia'' has a Gondwanan distribution, with most species found Australia, ...

Poa Flabellata
''Poa flabellata'', commonly known as tussac grass or just tussac, is a tussock grass native to southern South America, the Falkland Islands, South Georgia and other islands in the South Atlantic. There are also two isolated records from the herbarium at the French Muséum national d'histoire naturelle for the Île Amsterdam in the Indian Ocean. It was introduced to Shetland, Scotland for basket making in 1844, and possibly as a source of fodder because of its ability to grow in hostile conditions.. It grows in dense clumps, usually about high (although they can be much taller), on wet coastal land and is a dominant feature of much of the landscape. Associated organisms The plant community dominated by ''P. flabellata'' is widely used by birds and mammals. Breeding colonies of southern fur seal, elephant seal, Magellanic penguin, macaroni penguin, and albatrosses are all found amongst tussac grass on South Georgia and elsewhere. The austral thrush is predominantly found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juncus Inconspicuous
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plants that superficially resemble grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the most widespread and familiar species, the leaves are reduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
