Treubiaceae
Treubiaceae is a family of liverworts in the order Treubiales.Crandall-Stotler, Barbara. & Stotler, Raymond E. "Morphology and classification of the Marchantiophyta". page 63 ''in'' A. Jonathan Shaw & Bernard Goffinet (Eds.), ''Bryophyte Biology''. (Cambridge: Cambridge University Press:2000).

Apotreubia
''Apotreubia'' is a genus of liverworts in the family Treubiaceae. There are four species, including: '' Apotreubia nana'', which is found in subalpine New Guinea, and '' Apotreubia pusilla'', which has a disjunct distribution between eastern Asia (Himalayas to Japan) and British Columbia. The genus name of ''Apotreubia'' is in honour of Melchior Treub (1851–1910), who was a Dutch botanist. He worked at the Bogor Botanical Gardens in Buitenzorg on the island of Java, south of Batavia, Dutch East Indies Batavia was the capital of the Dutch East Indies. The area corresponds to present-day Jakarta, Indonesia. Batavia can refer to the city proper or its suburbs and hinterland, the Ommelanden, which included the much-larger area of the Residen ..., gaining renown for his work on tropical flora.

Treubia
''Treubia'' is a genus of liverworts in the family Treubiaceae.Crandall-Stotler, Barbara. & Stotler, Raymond E. (2000). "Morphology and classification of the Marchantiophyta". pages 21–70 ''in'' A. Jonathan Shaw & Bernard Goffinet (eds.), ''Bryophyte Biology''. (Cambridge: Cambridge University Press). There are seven species, all of which are restricted to the southern hemisphere. Five of the species occur in Australasia and the other ('' Treubia scapanioides'') occurs in Chile. All species are dioicous, with separate male and female gametophyte A gametophyte () is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the ...s.

Metzgeriales
Metzgeriales is an Order (biology), order of Marchantiophyta, liverworts. The group is sometimes called the simple thalloid liverworts: "thallus, thalloid" because the members lack structures resembling stems or leaves, and "simple" because their tissues are thin and relatively cellular differentiation, undifferentiated. All species in the order have a small gametophyte stage and a smaller, relatively short-lived, sporophyte, spore-bearing stage. Although these plants are almost entirely restricted to regions with high humidity or readily available moisture, the group as a whole is widely distributed, and occurs on every continent except Antarctica. Description Members of the Metzgeriales typically are small and thin enough to be translucent, with most of the tissues only a single cell layer in thickness. Because these plants are thin and relatively undifferentiated, with little evidence of distinct tissues, the Metzgeriales are sometimes called the "simple thalloid liverwor ...

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 ...

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...
