Lepidozia Reptans
''Lepidozia reptans'' is a species of liverwort belonging to the family Lepidoziaceae. It has cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The ext .... References {{Taxonbar, from=Q601791 Lepidoziaceae Taxa named by Carl Linnaeus ...

Liverwort
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly diff ...

Lepidoziaceae
Lepidoziaceae is a family of leafy liverworts. It is a group of small plants that are widely distributed. Most of the species of this family are found in tropical regions. The main characteristics of the family: 1. Oil bodies are small and unsegmented. 2. The leaves are never folded. 3a. In larger species, the leaves are three or four lobed (often dentate) and have an incubous insertion. 3b. In smaller species, the leaves may be divided to their base as filaments. Description Species may range from a light to dark green, with some species of ''Bazzania'' bluish-green to brown. When the plants branch, the branches do not grow from the underside of the stem. Differentiation Here are the Bazzania okaritana. The underleaves of Bazzania nova Engel & G.L.Sm. have thick walls and are chlorophyllose; only one other species has similar underleaves, but its leaves are smaller and have four or six finger-like lobes. Underleaf of Bazzania species often has a markedly asymmetrical ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
