		Traditionally, the liverworts were grouped together with other bryophytes (mosses and hornworts) in the Division Bryophyta, within which the liverworts made up the class Hepaticae (also called Marchantiopsida).
		& Stotler, Raymond E. "Morphology and classification of the Marchantiophyta".
		It is estimated that there are 6000 to 8000 species of liverworts, at least 85% of which belong to the leafy group.

	Marchantiophyta - Wikipedia, the free encyclopedia
		The Marchantiophyta is a division of plants commonly called hepatics or liverworts.
		Originally, the Marchantiophyta were grouped as class Hepaticae alongside the mosses in the Division Bryophyta, but the liverworts are now usually given their own division with two classes: Jungermanniopsida (simple thalloids and leafy liverworts) and the Marchantiopsida (complex-thallus liverworts and bottle hepatics).

		Marchantiophyta (liverworts) are non-vascular plants, also called hepatics or Hepaticophyta.
		However, since this grouping makes the Bryophyta paraphyletic, the liverworts are now usually given their own division, Marchantiophyta, with two classes: Jungermanniopsida (simple thalloids and leafy liverworts) and the Marchantiopsida (complex-thallus liverworts and bottle hepatics).
		Liverworts appear to have diverged from all other embryophyte plants near the beginning of their evolution.

		The Marchantiophyta are a division of bryophyte plants commonly referred to as hepatics or liverworts.
		Another Devonian fossil called Protosalvinia also looks like a liverwort, but its relationship to other plants is still uncertain, so it may not belong to the Marchantiophyta.
		This divisional name is based on the name of the most universally recognized liverwort genus Marchantia.

		- Typifications in the genus Fossombronia (Marchantiophyta) - Problems and solutions.
		Due to the overwhelming lack of modern taxon studies in the Marchantiophyta, relatively few species have been typified.
		As a result, it is not uncommon to find that the current interpretation of a species is not compatible with the actual type specimen.

		This NSF Assembling the Tree of Life (ATOL) project aims to resolve the liverwort Tree of Life.
		There is mounting evidence that liverworts (Phylum Marchantiophyta) were the first green plants to diversify on land some 500,000 million years ago and as such they are the oldest living lineage of land plants.
		This species-rich group of small green plants is remarkably diverse in structure, and includes ancient lineages as well as more recent radiations of closely related species.

		Analyses of molecular data support the partitioning of the Marchantiophyta into two classes, the Marchantiopsida and Jungermanniopsida.
		The latter is subdivided into the Metzgeriidae (simple thalloids) and the Jungermanniidae (leafies).
		The relative value of different characters in defining relationships will be evaluated, and the overall strength of the phylogenetic signal in the data set will be assessed.

		The simple thalloid liverworts use several forms of asexual reproduction with gemmae often serving as significant taxonomic characters.
		(Blasiales, Marchantiophyta), a Japanese endemic, bears multicellular stalked gemmae within specialized receptacles.
		Two kinds of gemmae have been described: a lenticular, discoid form with serrulate margins and two opposite marginal notches, and a smaller, spherical form.

		Over the last decade, recent advances in DNA sequencing technology and analytical approaches to phylogenetic reconstruction, including the use of ultra-structural, morphological and anatomical data, have enabled unprecedented progress toward our understanding of plant evolution.
		A growing consensus suggests that the bryophytes possibly represent three separate evolutionary lineages, which are today recognized as mosses (phylum Bryophyta), liverworts (phylum Marchantiophyta) and hornworts (phylum Anthocerotophyta).
		The greatest species diversity in bryophytes is found in the mosses, with estimates of the number of species ranging from 10,000 to 15,000.
