English: Mossen; Mosses; Mosses family.
Synonym: Bryopsida;
Musci.
Clades: Bryopohyta;
Plants.
Genera: 800; 12700 species.
Region: worldwide
Habitat: all terrestrial; from the cold and barely hospitable antarctic to lush tropical rainforests.
BotanyDown-growing mosses are pleurocarp, as the sporophytes grow at small sides. If the sporophytes grow on the sprout tip, then the acrocarp is called.
Pleurokarp and akrokarp are the two large groups in the Laubmoosen; leaves with 1 tip.
Mosses have many ecological functions, and one group, the peat mosses (Sphagnum), perform an important role in the global biogeochemical cycling of carbon where they represent a large reservoir of sequestrated carbon in the form of northern boreal peatlands (Wieder & Vitt 2006).
TaxonomyThe name
Bryophyta is confusing as it is used for both all mosses and the real mosses. That is the reason to adopt the name
Bryanae for this clade. The class is a class, with are giving the ending -anae. The ending for phyla is -phyta.
Clades: Bryopohyta;
Plants.
In most classifications
Bryanae, mostly named
Bryophyta, is a Class in the Phylum Bryopohyta. It is divided in 8 Subclasses. Seven of them have hardly any genera, most of them only 1.
The main Subclass is Bryopsida with 6 Subclasses. Three of them consist of 1 genus, one has 40 genera and then there are two main subclasses
Dicranidae and
Bryidae.
Plant theoryIn the
Plant theory the above classification does not work. The imbalance in extension of the several clades is enormous.
There should be 3 Subclasses, fitting the series.
1
Hydrogen series:
Takakiidae, with 1 genus Takakia
2.
Carbon series:
Dicranidae3.
Silicon series:
BryidaeTakakiopsida ias the first clade is placed in the hydrogen series Subclass, provionary as there is no information about Takakia.
The small primary clades in the classification are fused in the first order in
Dicranidae, the
Funariales.
