It contains the following species: * ''Fulfordianthus evansii'' * '' Fulfordianthus pterobryoides'' The genus name of ''Fulfordianthus'' is in honour of Margaret Hannah Fulford (1904–1999), who was an American bryologist who was active in identifying the flora of North and South America. The genus was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon.

Margaret Hannah Fulford
Margaret Hannah Fulford (June 14, 1904 – November 28, 1999) was an American bryologist who was active in identifying the flora of North and South America. Biography Fulford was born on June 14, 1904, in Cincinnati, Ohio. She subsequently attended the University of Cincinnati. She earned her BA in botany in 1926, BE in education in 1927, and returned for her MA in botany working under Emma Lucy Braun in 1928. She then attended Yale University to obtain her doctorate under Alexander William Evans, which she accomplished in 1935. Meanwhile, she worked at the University of Cincinnati as a botany instructor from 1927 to 1940. She became assistant professor in 1940, associate professor in 1946, professor in 1954, and professor emerita in 1974. She remained with the university until her death. Fulford's focus was on morphology, ecology, and systematics of leafy hepatics. She intensely studied the reproduction and life cycle of the Hepaticae. She was a leading member of the Sulliv ...

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.

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 ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...
