The classification of Lejeuneeae, the most speciose tribe of the largely epiphytic leafy liverwort family Lejeuneaceae, is deemed notoriously difficult and hampered by extensive morphological homoplasy. We employed sequences of two chloroplast regions (trnL-trnF, rbcL) and the nuclear ribosomal ITS region of several critical taxa to explore their phylogenetic position. Based on our phylogenetic analyses and accompanying morphological investigations, we transfer Microlejeunea aphanella to… 

Integrative Taxonomy Reveals a New Species of the Genus Lejeunea (Marchantiophya: Lejeuneaceae) from Peninsular Malaysia

Two clades of Lejeunea are considered as two distinct species and a new species, L. malaysiana for L. cocoes morpho-species with caducous leaves with ribbon-like and plantlet regenerants is described.

Molecular and morphological evidence for a new species of liverwort, Lejeunea heinrichsii (Marchantiophyta: Lejeuneaceae) from Taveuni, Fiji

A new species from Fiji, Lejeunea heinrichsii is described and illustrated herein based on morphological characters and molecular phylogenetic analyses, which revealed that the two species are very distinct.

Lepidolejeunea grandiocellata sp. nov. (Lejeuneaceae, Porellales), a New Leafy Liverwort from the West Indies Based on Morphological and Molecular Evidence

Based on the phylogeny and the characters of the ocelli, L. grandiocellata is placed in a new subgenus Caribeolejeunea, and is characterized by o celli in basal parts of leaves, underleaves, bracteoles and bracts often being conspicuously larger than the surrounding cells.

A phylogeny of Cephaloziaceae (Jungermanniopsida) based on nuclear and chloroplast DNA markers

The most comprehensively sampled phylogeny available to date based on the nuclear ribosomal internal transcribed spacer region and the chloroplast markers trnL-trnF and rbcL of 184 accessions representing 41 of the 89 currently accepted species and four of the five currently accepted subfamilies is presented.

Thiersianthus (Marchantiophyta: Lejeuneaceae), a new genus from lowland rainforests in Borneo

A new genus is proposed, Thiersianthus, to accommodate an undescribed ocellate taxon in the lowland ultramafic rainforests of Sabah, Borneo, which phylogenetic analyses suggest belongs to the subtribe Lepidolejeuneinae of Lejeuneaceae.

Yanoella (Marchantiophyta: Lejeuneaceae), a new genus from the Brazilian Atlantic Forest

A new genus Yanoella is proposed for accommodating the remarkable Brazilian species, which is characterized by the granular oil bodies in median and basal chlorophyllose cells of the leaf lobe and presence of Allorgella-type marginal denticulations, which are striking characters of the subtribe Echinolejeuneinae.

Crown Group Lejeuneaceae and Pleurocarpous Mosses in Early Eocene (Ypresian) Indian Amber

Evidence for lejeuneoid liverworts and pleurocarpous mosses in Cambay amber is presented and the liverwort fossil is described as the extinct species Microlejeunea nyiahae, representing the oldest crown group fossil of Lejeuneaceae.

Reinerantha foliicola, a new genus and species of Lejeuneaceae subtribe Cololejeuneinae (Marchantiophyta) from Ecuador

A new, epiphyllous genus and species in Cololejeuneinae from the Western Cordillera of Ecuador, Reinerantha foliicola is described and analysis of combined molecular datasets with parsimony, maximum likelihood and Bayesian methods revealed it in a sister relationship to the large pantropical genus Diplasiolejeunea.

Gaolejeunea, a new genus from China and new member of subtribe Echinolejeuneinae (Lejeuneaceae, Marchantiophyta)

It is suggested that C. gaoi should be established as a new genus, Gaolejeunea, based on the results of phylogenetic analyses and morphological data, combined with the recommendations of the IUCN Red List criteria.

Geographical structure, narrow species ranges, and Cenozoic diversification in a pantropical clade of epiphyllous leafy liverworts

The clear geographic structure of the Leptolejeunea crown group points to evolutionary processes including rare long‐distance dispersal and subsequent speciation.



Molecular Phylogeny of the Leafy Liverwort Lejeunea (Porellales): Evidence for a Neotropical Origin, Uneven Distribution of Sexual Systems and Insufficient Taxonomy

The first global phylogeny of Lejeunea is presented and the first example of a Neotropical origin of a Pantropical liverwort genus is presented, providing a framework for future studies on the diversification of this lineage in space and time.

Towards a monophyletic classification of Lejeuneaceae II: subtribes Pycnolejeuneinae and Xylolejeuneinae subtr. nov., transfer of Otolejeunea to Lepidolejeuninae, and generic refinements

P phylogenetic analyses of a three marker dataset derived from 113 accessions of Lejeuneeae and 13 outgroup species are presented and the new subtribes Pycnolejeuneinae and Xylolejeuniinae are proposed and reinstate the genera Cystolejeunesa and Cyrtolejeunea are reinstated.

Towards a monophyletic classification of Lejeuneaceae V: the systematic position of Pictolejeunea

The derived liverwort Leiolejeunea grandiflora was recollected at the type locality in Jamaica after more than 100 years and the characteristics of its oil bodies were described for the first time based on the new collections, and a wide genus concept for CheilolejeuneA is proposed to avoid nomenclatural confusion.

Tramps, narrow endemics and morphologically cryptic species in the epiphyllous liverwort Diplasiolejeunea.

Towards a monophyletic classification of Lejeuneaceae I: subtribe Leptolejeuneinae subtr. nov.

Contrary to earlier belief, Leptolejeunea formed an early diverging, robust monophyletic lineage within Lejeuneaceae tribe Lejeuneeae and is not closely related to Drepanolejeunia.

Phylogeny and Classification of Lejeuneaceae Subtribe Cheilolejeuneinae (Marchantiophyta) Based on Nuclear and Plastid Molecular Markers

A molecular phylogeny of Cheilolejeuneinae and related lineages is presented based on maximum parsimony and maximum likelihood analyses, as well as Bayesian inference of two chloroplast regions (trnL-F, trnG) and the nuclear ribosomal ITS1-5 region, to test the monophyly of this subtribe, and to re-evaluate the infrageneric classification.

Size doesn´t matter—recircumscription of Microlejeunea (Lejeuneaceae, Porellales) based on molecular and morphological evidence
