Abstract Pelliales is a basal lineage of the simple thalloid liverworts. Here, we describe a thalloid liverwort from the Middle Jurassic Xishanyao Formation of the Turpan–Hami Basin, Xinjiang Uygur Autonomous Region in northwestern China. The thalloid fossil liverwort is described as a new species: Pellites hamiensis (Pelliaceae, Pelliales). Pellites hamiensis nov. sp. resembles the extant species of Pelliaceae in having ribbon-like segments, conspicuous costae that appear as ridges on the…

Divergent evolutionary trajectories of bryophytes and tracheophytes from a complex common ancestor of land plants
TLDR
It is confirmed that extant tracheophytes and bryophytes are both highly derived; as a result, understanding the origin of land plants requires tracing character evolution across the diversity of modern lineages.

Pelliaites deccanii gen. et. sp.nov., a bryophytic sporogonium from the intertrappean beds of Mohgaonkalan, M. P., India
TLDR
The present specimen does not show any resemblance with reported fossil specimens but its affinities with the living genus Pellia are very prominent and the fossil specimen is named as Pelliaites deccanii.
A new thalloid liverwort: Pallaviciniitessandaolingensis sp. nov. from the Middle Jurassic of Turpan–Hami Basin, NW China
Here we described a fossil thalloid liverwort from the Middle Jurassic Xishanyao Formation, Turpan–Hami Basin, China, preserved as a carbonized compression in greyish-green siltstones. The fossil…

The liverwort family Ricciaceae has a very sparse fossil record in contrast to its large number of living species and its wide distribution. Fossil thalli collected from the Middle Jurassic Xishanyao…
Kaolakia borealis nov. gen. et sp. (Porellales, Jungermanniopsida): A leafy liverwort from the Cretaceous of Alaska
TLDR
A fragment of a leafy liverwort preserved in Cenomanian amber from northern Alaska is described and placed in a new genus, Kaolakia, which likely represents an extinct lineage with affinities to Porellales, the primarily epiphytic clade of the leafy Liverworts, and is possibly closely related to Frullaniaceae.
On the morphology, systematics and phylogeny of Noteroclada (Noterocladaceae, Marchantiophyta)
TLDR
These studies show that there are two forms of perennating tubers, which are geographically partitioned, that plants are always monoicous, that sporophytes are enclosed by a shoot calyptra and Fossombronia-like caulocalyx and that sporeling ontogeny is different from that of Pellia.

Illuminating the evolutionary history of liverworts (Marchantiophyta)—towards a natural classification
TLDR
The Jungermanniales are most probably a recently diversified group which has attained the greatest profusion of structure and the most remarkable diversity of leaf development and protective devices for maturing sporophytes.
Phylogenetic relationships of the liverworts (Hepaticae), a basal embryophyte lineage, inferred from nucleotide sequence data of the chloroplast gene rbcL.
TLDR
Maximum likelihood and parsimony analyses of chloroplast-encoded gene rbcL data confirm hypotheses based on morphological data, such as the paraphyly of bryophytes, and the basal position of liverworts, as well as corroborate the deep separation between the complex thalloid and leafy/simple thalloids implied by morphology data.
Progress towards a robust phylogeny for the liverworts, with particular focus on the simple thalloids (Selected Papers Presented at the 15 World Congress on Bryology Held at Merida, Venezuela, January 12-16, 2004)
TLDR
An eight locus analysis using sequences from the chloroplast rbeL, rps4, psbA, alp8 and trnLuAA regions for 64 liverworts, nine mosses and five hornworts resolves five well supported lineages within the Marchantiophyta.
Divergence times and the evolution of morphological complexity in an early land plant lineage (Marchantiopsida) with a slow molecular rate.
TLDR
A complete generic-level phylogeny of the complex thalloid liverworts, a lineage that includes the model system Marchantia polymorpha, provides a temporal framework for the analysis of the evolution of critical traits essential for plants during land colonization.
