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 ...

Brachytheciaceae
Brachytheciaceae is a family of mosses from the order Hypnales. The family includes over 40 genera and 250 species. Description The family consists of pleurocarpous mosses with very diverse appearances. They are irregular or pinnately branched and form loose mats. The leaves are broad ovate or triangular and are sharply focused at the top. A midrib is always present and usually reaches more than half of the leaf. The leaf cells are prosenchymatous and are many times longer than wide and interlocking with pointed ends. The sporophyte consists of a regularly formed spore capsule that stands straight on the setae. The spores are distributed through an annular peristome, which is closed off by a beak-shaped operculum in immature plants. Habitat Species are terrestrial, epiphytic, or lithophytic plants that are distributed around the world. They grow on various substrates, including rock, bark, and soil. Taxonomy Brachytheciaceae is in the order Hypnales. They are a sister group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
