Plagiomnium Venustum
''Plagiomnium venustum'', also known as magnificent leafy moss, is a species of moss belonging to the family Mniaceae. It is found mainly in western North America along the coastal region. This moss can be identified from other members of the Plagiomnium genus by dark coloured stomata guide cells and the absence of sterile stems. It is most commonly found growing as a mat on a variety of substrate, but mainly on humus and moist soil. Range and habitat Majority of the ''Plagiomnium venustum'' species have been recorded in British Columbia, Canada and Oregon, United States, making it a Pacific Coast Bryophyte. However, some have also been found in Washington, Idaho, and Montana, United States. They are most common on low to moderate elevations. This moss likes to grow in moist soil of forest floors, on tree trunks, rotten tree logs, and on rocks and cliffs. Morphology ''Plagiomnium venustum'' exhibits an acrocarpous growth form, so the shoots are upright and unbranched. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plagiomnium
''Plagiomnium'' is a genus of mosses in the family Mniaceae. It was formerly a part of a more encompassing genus ''Mnium'' and in 1968 Finish bryologist Timo Juhani Koponen justified splitting the genus into a number of smaller genera. Description This genus is characterized by singly placed marginal teeth. ''Plagiomnium'' are commonlyg found along shaded stream banks, seeps and springs, generally on soil with a high humus content.

Bryopsida
The Bryopsida constitute the largest class of mosses, containing 95% of all moss species. It consists of approximately 11,500 species, common throughout the whole world. The group is distinguished by having spore capsules with teeth that are ''arthrodontous''; the teeth are separate from each other and jointed at the base where they attach to the opening of the capsule.Buck, William R. & Bernard Goffinet. (2000) "Morphology and classification of mosses", pages 71-123 ''in'' A. Jonathan Shaw & Bernard Goffinet (Eds.), ''Bryophyte Biology''. (Cambridge: Cambridge University Press). Consequently, mosses in the Class Bryopsida are commonly known as the “joint-toothed” or “arthrodontous” mosses. These teeth are exposed when the covering operculum falls off. In other groups of mosses, the capsule is either ''nematodontous'' with an attached operculum, or else splits open without operculum or teeth. Morphological groups The Bryopsida can be simplified into three groups: the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moss Life Cycle
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 ...
