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 ...

Lejeuneaceae
Lejeuneaceae is the largest family of liverworts. Most of its members are epiphytes found in the tropics, while others can be found in temperate regions. The main characteristics of the family are that: #The leaves are incubous. #Amphigastrium is usually present, sometimes reduced. #Leaves are divided into lobe and lobule. #Archaegonium in a perianth. Some large genera of the family are ''Lejeunea'', '' Ceratolejeunea'' (around 84 species,) and '' Cheilolejeunea'' (around 275 species,). Taxonomy The Lejeuneaceae are the largest family of liverworts with more than 1600 species, which equates to roughly 20% to 25% of all liverworts. These species are assigned to 95 genera.Crandall-Stotler, Barbara. & Stotler, Raymond E. "Morphology and classification of the Marchantiophyta". pages 62-63 ''in'' A.
