Fissidentaceae
Fissidentaceae is a family of haplolepideous mosses (Dicranidae The Dicranidae are a widespread and diverse subclass of mosses in class Bryopsida, with many species of dry or disturbed areas. They are distinguished by their spores; the peristome teeth are haplolepideous with a 4:2:3 formula, and an exostome ...) in the order Dicranales, with a single genus, '' Fissidens''. It was formerly placed in the now-obsolete order Fissidentales. References Moss families Monogeneric plant families {{dicranidae-stub ...

Fissidens Dubius
''Fissidens dubius'', commonly known as the rock-pocket moss, is a species of moss belonging to the family Fissidentaceae. First species description, described by Palisot de Beauvois in 1805 from material collected in Philadelphia, it is a relatively large moss growing up to tall that forms loose to dense mats on calcareous substrates. The species is characterised by its leaf margins, pale border of thick-walled cells, and typically dioicous reproduction. It has a broad global distribution across Europe, North and South America, Asia, North Africa, and New Zealand, occurring in various habitats from lowlands to alpine climate, alpine zones, particularly in shaded locations on basic soils and rocks. While morphology (biology), morphologically similar to ''Fissidens adianthoides, F. adianthoides'', ''F. dubius'' is distinguished by its smaller leaf cells and irregularly thickened leaf tips. The species is classified as least-concern species, Least Concern due to its stabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 mosses In mosses, the peristome is a specialized structure in the sporangium that allows for gradual spore discharge, instead of releasing them all at once. Most mosses produce a capsule with a lid (the operculum (botany), operculum) which falls off when the spores inside are mature and thus ready to be dispersed. The opening thus revealed is called the ''stoma'' (meaning "mouth") and is surrounded by one or two peristomes. Each peristome is a ring of triangular "teeth" formed from the remnants of dead cells with thickened cell walls. There are usually 16 such teeth in a single peristome, separate from each other and able to both fold in to cover the stoma as well as fold back to open the stoma. This articulation of the teeth is term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Dicranidae
The Dicranidae are a widespread and diverse subclass of mosses in class Bryopsida, with many species of dry or disturbed areas. They are distinguished by their spores; the peristome teeth are haplolepideous with a 4:2:3 formula, and an exostome is absent. Systematics Traditionally, the Dricanidae comprised about six to eight orders. However, phylogenetic analysis using molecular markers suggested that Dicranales was paraphyletic with respect to Pottiales Pottiales is an order (biology), order of mosses in the subclass Dicranidae. Classification The following families are recognised in ''Bryophyte Biology'': *Pottiaceae *Pleurophascaceae *Serpotortellaceae *Mitteniaceae Some other families .... A recently phylogenomic analysis led to a break-up of Dicranales and creation of a number of new small orders. The phylogenetic relationships recovered within Dicranidae are shown in the cladogram below. The orders Bryoxiphiales, Pseudoditrichales and Mitteniales were not ...
