Tetraphidopsida
Tetraphidaceae is a family of mosses. It includes only the two genera '' Tetraphis'' and '' Tetrodontium'', each with two species. The defining feature of the family is the 4-toothed peristome. Range This family of mosses is most commonly found in northern latitudes. ''Tetraphis'' ''Tetraphis pellucida'' is the most common species in the family and is usually found in deciduous forests. Its leaves become wider in colder climates, which often leads to a misclassification of the species. ''Tetraphis geniculata'' is less commonly found and also appears in northern latitudes. The species often grows alongside the only other species in the genus, ''T. pellucida''. Both ''Tetraphis'' species are found growing on moist sedimentary rocks and also on soil with high organic content, but the genus is mostly found growing on rotting logs. ''Tetrodontium'' '' Tetrodontium brownianum'' grows most frequently on wet and shady rocks, of either granite or sandstone. The species normally ...

Moss Families
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 appr ...

Tetrodontium Brownianum
''Tetrodontium brownianum'' is a species of moss commonly known as Brown's tetrodontium moss or Brown's four-tooth moss. It is widely distributed. In North America it is found in Washington state and British Columbia on the west coast and from Newfoundland to Ohio to the east."Bryophyte Flora of North America: Tetrodontium brownianum" efloras.org.

Tetraphis Pellucida (e, 142735-474310) 9286
''Tetraphis pellucida'', the pellucid four-tooth moss, is one of two species of moss in the acrocarpous genus ''Tetraphis''. Its name refers to its four large peristome teeth found on the sporophyte capsule. Range and morphology ''Tetraphis pellucida'' occurs almost exclusively on rotten stumps and logs, and is native to the northern hemisphere. The leafy shoot is between eight and 15 mm tall. The lower leaves are 1 to 2 mm long, whereas the upper and perichaetial leaves – leaves that surround the archegonia – are 3 mm long. The leaves are plain and whole at the margins. Reproduction ''Tetraphis pellucida'' reproduces both asexually through the production of gemmae, and sexually resulting in a sporophyte which will produce spores. Asexual reproduction ''Tetraphis pellucida'' reproduces asexually through the use of propagules called gemmae. The gemmae are found either in gemma cups or stalks. Gemma cups are typically composed of three to five larger, speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetrodontium Repandum
''Tetrodontium repandum'', the small four-tooth moss, is a moss in the family Tetraphidaceae.Schwägrichen, Christian Friedrich. Species Muscorum Frondosorum, Supplementum Secundum 2: 102. 1824.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
