Hennediella
''Hennediella'' is a genus of mosses belonging to the family Pottiaceae. The genus name of ''Hennediella'' is in honour of Roger Hennedy (1809 - 1877), who was a Scottish printer and botanist ( Pteridology). The genus was circumscribed by Jean Édouard Gabriel Narcisse Paris in Index bryologicus (Paris) vol.2 on page 557 in 1895. The genus has cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats.

Pottiaceae
The Pottiaceae are a Family (biology), family of mosses. They form the most numerous moss family known, containing nearly 1500 species or more than 10% of the 10,000 to 15,000 moss species known. Genera The family has four subfamilies and 83 genera. * Subfamily Trichostomoideae **''Bryoceuthospora'' **''Calymperastrum'' **''Calyptopogon'' **''Chionoloma'' **''Eucladium'' **''Leptobarbula'' **''Neophoenix'' **''Pachyneuropsis'' **''Pleurochaete'' **''Pottiopsis'' **''Pseudosymblepharis'' **''Quaesticula'' **''Streptocalypta'' **''Tetracoscinodon'' **''Tetrapterum'' **''Tortella (plant), Tortella'' Lindb. **''Trachycarpidium'' **''Trichostomum'' **''Oxystegus'' **''Tuerckheimia (plant), Tuerckheima'' Broth. **''Uleobryum'' **''Weissia'' **''Weissiodicranum'' * Subfamily Barbuloideae **''Anoectangium'' **''Barbula'' **''Bellibarbula'' **''Bryoerythrophyllum'' **''Cinclidotus'' **''Dialytrichia'' **''Didymodon'' (e.g. ''Didymodon tomaculosus'') **''Erythrophyllopsis'' **''Ganguleea' ...

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 ...

Pteridology
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
