Leptodictyum Riparium
''Leptodictyum riparium'', commonly known as Kneiff's feathermoss, streamside leptodictyum moss, or knapwort, is a species of moss of cosmopolitan distribution. The only places it is not found are the Pacific Islands and Australia. It is commonly found growing in the lakes and rivers of Minnesota and is also present in Mexico, Guatemala, the Bahamas, Cuba, Jamaica, Haiti Haiti (; ht, Ayiti ; French: ), officially the Republic of Haiti (); ) and formerly known as Hayti, is a country located on the island of Hispaniola in the Greater Antilles archipelago of the Caribbean Sea, east of Cuba and Jamaica, and ..., the Dominican Republic, Venezuela, Peru and Brazil. This moss has several different forms and can grow up to 30 cm. Its ovate leaves, which are in two rows, are often pointed at their apex. ''Leptodictyum riparium'' has been found in an acidic mining lake and can live at a pH down to 1.6 in volcanic craters. It was once found with '' Eleocharis acicul ...

Amblystegiaceae
Amblystegiaceae is a family of mosses. It includes 20 to 30 genus, genera with a total of up to 150 species.Amblystegiaceae.
Flora of North America. Volume 28.
They occur nearly worldwide, growing in tropical, temperate, and subpolar regions. These mosses are small to large in size and are yellow, green, or brown in color. Some are aquatic and some terrestrial. Most occur in wet habitat types. Many occur in substrates with a basic pH, but some grow in neutral to acidic substrates.Watson, L., and Dallwitz, M.J. 2005 onwards

Mosses
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 app ...

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 ...
