An example of moss (Bryophyta) on the forest floor in Broken Bow, Oklahoma. Bryophytes (/ ˈ b r aɪ. ə ˌ f aɪ t s /) [2] are a group of land plants (embryophytes), sometimes treated as a taxonomic division, that contains three groups of non-vascular land plants: the liverworts, hornworts, and mosses. [3]
Individual plants 20–30 cm (8–12 in) or more long are common in Sphagnum species for example. But even aquatic species of moss and other bryophytes needs their mature capsules to be exposed to air by seta elongation or seasonal lowering of water level to be able to reproduce. [60]
Bryophytes, an informal group that taxonomists now treat as three separate land-plant divisions, namely: Bryophyta (mosses), Marchantiophyta (liverworts), and Anthocerotophyta (hornworts). In all bryophytes, the primary plants are the haploid gametophytes , with the only diploid portion being the attached sporophyte, consisting of a stalk and ...

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.

Hypnales is the botanical name of an order of Bryophyta or leafy mosses.This group is sometimes called feather mosses, referring to their freely branched stems. [1] The order includes more than 40 families and more than 4,000 species, making them the largest order of mosses.
The overall physical similarity of some mosses and leafy liverworts means that confirmation of the identification of some groups can be performed with certainty only with the aid of microscopy or an experienced bryologist. Liverworts, like other bryophytes, have a gametophyte-dominant life cycle, with the sporophyte dependent on the gametophyte ...
Bryophytes — non-vascular plants, that include mosses, hornworts, and liverworts. They are cryptogams ( spore -plants). The study of Bryophytes is named bryology .
