Pelliaceae
Pelliaceae is a family of liverworts which has included three genera: '' Pellia'' (in the temperate Northern Hemisphere) and '' Noteroclada'' (in the Southern Hemisphere), and '' Androcryphia''. The three genera are easily distinguished, not only because they occur in completely separate regions of the world, but because ''Noteroclada'' has a leafy appearance, while ''Pellia'' is more clearly thallose. ''Androcryphia'' is much less common, and bears similarities to the foliose members of Jungermanniales Jungermanniales is the largest order of liverworts. They are distinctive among the liverworts for having thin leaf-like flaps on either side of the stem. Most other liverworts are thalloid, with no leaves. Due to their dorsiventral organization ....

Pellia
''Pellia'' is a small but widespread genus of liverworts in the cool and temperate regions of the northern hemisphere. It is classified in order Pelliales and is a member of the family Pelliaceae within that order.

Pellia Epiphylla
''Pellia epiphylla'' (sometimes known as overleaf pellia or common pellia) is a species of thallose liverwort. It occurs in North America, Europe, North Africa and parts of Asia.Smith, A. J. E. (1989) ''The Liverworts of Britain and Ireland'', Cambridge University Press. It grows in patches in damp, sheltered places on neutral or acidic substrates. It is common on the banks of rivers, streams and ditches and also grows in wet woodland, marshes and on wet rocks.Atherton, Ian; Sam Bosanquet & Mark Lawley, ''eds.'' (2010) ''Mosses and Liverworts of Britain and Ireland: a field guide'', British Bryological Society. Description The thalli are irregularly branched and are fairly large, growing to over 1 cm wide and several centimetres long.Watson, E. V. (1981) ''British Mosses and Liverworts'', Cambridge University Press. They are green, sometimes with a red or purple tinge. They are fairly featureless with an ill-defined midrib and no visible network of cells on the surface. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noteroclada
''Noteroclada'' is a small genus of liverworts of the Southern Hemisphere. It is classified in order Pelliales and is the only genus in the family Noterocladaceae within that order. Unlike ''Pellia'', the other genus in the order, ''Noteroclada'' has a leafy appearance. The species ''Noteroclada confluens'' is known primarily from the southern regions of South America, although it has been reported as far north as Costa Rica, and there is a report from New Zealand. A possible second species is known from South Africa South Africa, officially the Republic of South Africa (RSA), is the Southern Africa, southernmost country in Africa. It is bounded to the south by of coastline that stretch along the Atlantic Ocean, South Atlantic and Indian Oceans; to the ....Schuster, Rudolf M.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Marchantiophyta
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 ...

Thallus (tissue)
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folio
The term "folio" (), has three interconnected but distinct meanings in the world of books and printing: first, it is a term for a common method of arranging sheets of paper into book form, folding the sheet only once, and a term for a book made in this way; second, it is a general term for a sheet, leaf or page in (especially) manuscripts and old books; and third, it is an approximate term for the size of a book, and for a book of this size. First, a folio (abbreviated fo or 2o) is a book or pamphlet made up of one or more full sheets of paper, on each of which four pages of text are printed, two on each side; each sheet is then folded once to produce two leaves. Each leaf of a folio book thus is one half the size of the original sheet. Ordinarily, additional printed folio sheets would be inserted inside one another to form a group or "gathering" of leaves prior to binding the book. Second, folio is used in terms of page numbering for some books and most manuscripts that ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jungermanniales
Jungermanniales is the largest order of liverworts. They are distinctive among the liverworts for having thin leaf-like flaps on either side of the stem. Most other liverworts are thalloid, with no leaves. Due to their dorsiventral organization and scale-like, overlapping leaves, the Jungermanniales are sometimes called "scale-mosses".
