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 ...

Distichiaceae
''Distichium'' is a genus of haplolepideous mosses (Dicranidae) in the monotypic family Distichiaceae. Taxonomy The genus ''Distichium'' has traditionally been considered part of family Ditrichaceae. However, phylogenetic analyses have found Ditrichaceae to be polyphyletic and ''Distichium'' part of a protohaplolepidous grade of early branching lineages in Dicranidae. Based on these studies ''Distichium'' was restored to Distichiaceae, where it was originally placed by Schimper (1860). The family is now placed in order Distichiales along with family Timmiellaceae Timmiellaceae is a family (biology), family of Peristome#In mosses, haplolepideous mosses (Dicranidae). It contains two genera, ''Luisierella'' and ''Timmiella'', that were formerly place in family Pottiaceae. Taxonomy The genera ''Luisierella' .... Species The genus contains the following species: *'' Distichium asperrimum'' *'' Distichium austroinclinatum'' *'' Distichium brachyphyllum'' *'' Distichium bra ...

Timmiellaceae
Timmiellaceae is a family (biology), family of Peristome#In mosses, haplolepideous mosses (Dicranidae). It contains two genera, ''Luisierella'' and ''Timmiella'', that were formerly place in family Pottiaceae. Taxonomy The genera ''Luisierella'' and ''Timmiella'' have been traditionally placed in family Pottiaceae in order Pottiales. However, phylogenetic analyses have found these genera to form a clade, as part of a protohaplolepidous grade of early branching lineages in Dicranidae, for which the family Timmiellaceae was erected. The family is now placed in order Distichiales along with family Distichiaceae. Genera and species The family contains the following genera and species: *''Luisierella'' **''Luisierella barbula'' **''Luisierella pusilla'' **''Luisierella stenocarpa'' *''Timmiella'' **''Timmiella acaulon'' **''Timmiella alata'' **''Timmiella anomala'' **''Timmiella barbuloides'' **''Timmiella brevidens'' **''Timmiella cameruniae'' **''Timmiella corniculata' ...

Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consist ... [...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] |
