Tetraphidopsida
Tetraphidaceae is a family of mosses. It includes only the two genera '' Tetraphis'' and '' Tetrodontium'', each with two species 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. It is the basic unit of Taxonomy (biology), .... 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 sedimenta ...

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 ap ...

Moss
Mosses are small, non-vascular plant, non-vascular flowerless plants in the taxonomic phylum, division Bryophyta (, ) ''sensu stricto''. Bryophyta (''sensu lato'', Wilhelm Philippe Schimper, Schimp. 1879) may also refer to the parent group bryophytes, which comprise Marchantiophyta, 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 leaf, leaves that are generally only one cell thick, attached to a plant stem, 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 sporangium, spores. They are typically tall, though some species ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. It is one of only two recognized species in the genus '' Tetrodontium'', and is native to subalpine regions of the Northern Hemisphere. It has been reported from Alaska, British Columbia, Washington state, Japan, and Europe. See also * List of extinct plants of the British Isles The following are plant species which are or have been held to be at least nationally extinct in the British Isles, since Britain was cut off from the European continent, including any which have been reintroduced or reestablished, not including r ...

Tetraphis Geniculata
''Tetraphis'' is a genus of two species of mosses (Bryophyta). Its name refers to its four large peristome Peristome (from the Greek language, Greek ''peri'', meaning 'around' or 'about', and ''stoma'', 'mouth') is an anatomical feature that surrounds an opening to an organ or structure. Some plants, fungi, and shelled gastropods have peristomes. In mo ... teeth. Reproduction The sex of ''Tetraphis'' shoots can transform depending on the shoot density. When a colony is sparse female—gemmae-producing—shoots dominate. When the colony is sufficiently dense they transform into male shoots. This density-dependent sexual reproduction strategy is common in fish but Tetraphis is the first moss in which this has been documented. References Tetraphidopsida Moss genera {{moss-stub ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...
