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 ...

Jungermanniaceae
''Jungermanniaceae'' is the namesake family of leafy liverworts. It is a group of small plants that are widely distributed. Several genera formerly included within the family are now classified in the Myliaceae or Solenostomataceae. Most of the species of this family are found in temperate regions. The main characteristics of the family: * The leaves are succubous. * The leaves are unlobed and never decurrent along the stem. * Perianth is terminal on the leading shoot. * Rhizoids are scattered along the stem. Description The branches do not grow from the underside of the stem when the plants branch. The leaves are unlobed and have a smooth edge, and the underlobes are vestigial or absent. The rhizoid Rhizoids are protuberances that extend from the lower epidermal cells of bryophytes and algae. They are similar in structure and function to the root hairs of vascular land plants. Similar structures are formed by some fungi. Rhizoids may be unic ...s are scattered along th ...
