Disceliaceae
''Discelium'' is the only genus of moss in the family Disceliaceae; it contains the single species ''Discelium nudum'', the flag-moss. This species is rare, but is widely distributed in cool and temperate climates of the Northern Hemisphere The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's Nort ....

Brid
Brigid ( , ; meaning 'exalted one' from Old Irish),Campbell, MikBehind the Name.See also Xavier Delamarre, ''brigantion / brigant-'', in ''Dictionnaire de la langue gauloise'' (Éditions Errance, 2003) pp. 87–88: "Le nom de la sainte irlandaise ''Brigit'' est un adjectif de forme *''brigenti''... 'l'Eminente'." Delamarre cites E. Campanile, in '' Langues indo-européennes'' ("The name of the Irish Saint Brigid is an adjective of the form *''brigenti''... 'the Eminent'"), edited by Françoise Bader (Paris, 1994), pp. 34–40, that Brigid is a continuation of the Indo-European goddess of the dawn like Aurora. Brigit or Bríg is a goddess of pre-Christian Ireland. She appears in Irish mythology as a member of the Tuatha Dé Danann, the daughter of the Dagda and wife of Bres, with whom she had a son named Ruadán. She is associated with wisdom, poetry, healing, protection, blacksmithing and domesticated animals. ''Cormac's Glossary'', written in the 9th century by Christian monk ...

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 ...

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North Pole. Owing to Earth's axial tilt of 23.439281°, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that affect many factors within the north coast. Such events include El Niño–Southern Oscillation. Trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents, which flow westward due to the Coriolis e ...

Bryopsida
The Bryopsida constitute the largest class of mosses, containing 95% of all moss species. It consists of approximately 11,500 species, common throughout the whole world. The group is distinguished by having spore capsules with teeth that are ''arthrodontous''; the teeth are separate from each other and jointed at the base where they attach to the opening of the capsule.Buck, William R. & Bernard Goffinet. (2000) "Morphology and classification of mosses", pages 71-123 ''in'' A. Jonathan Shaw & Bernard Goffinet (Eds.), ''Bryophyte Biology''. (Cambridge: Cambridge University Press). Consequently, mosses in the Class Bryopsida are commonly known as the “joint-toothed” or “arthrodontous” mosses. These teeth are exposed when the covering operculum falls off. In other groups of mosses, the capsule is either ''nematodontous'' with an attached operculum, or else splits open without operculum or teeth. Morphological groups The Bryopsida can be simplified into three groups: the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
