Integrative taxonomy of Lepidolejeunea (Jungermanniopsida: Porellales): Ocelli allow the recognition of two neglected species

open access: yesTAXON, 2015
Abstract Lepidolejeunea is a largely epiphytic, pantropical genus of leafy liverworts. While the phylogenetic position of Lepidolejeunea has been the subject of recent molecular investigations, the relationships within this genus have been little studied.

Diversification and Taxonomy of the Liverwort Jubula Dumort. (Jungermanniopsida: Porellales) Inferred from Nuclear and Chloroplast DNA Sequences

open access: yesSystematic Botany, 2010
Abstract Nucleotide sequence variation in the ITS1-5.8S-ITS2 region of nuclear ribosomal DNA and in the trnL-tmF region of cpDNA from 28 specimens of Jubula (Jubulaceae), and two outgroup species, was analyzed using maximum parsimony and maximum likelihood. The molecular topologies supported five to six allopatric taxa in Jubula.

Primer registro de una inclusión de planta hepática del género Frullania (Frullaniaceae, Porellales) en el ámbar miocénico de Chiapas, México

open access: yesPaleontología Mexicana, 2023
En México la diversidad de hepáticas es muy importante en zonas tropicales y subtropicales, desafortunadamente es poco lo que se ha descrito formalmente con base en material fósil. En este estudio se documenta por primera vez el género Frullania en el ámbar miocénico de Chiapas, sur de México.

Age estimates ofFrullania(Frullaniaceae, Porellales) main lineages: another example of rapid and recent diversification in liverwort evolution

open access: yesSystematics and Biodiversity, 2016
Frullania Raddi is an extant genus of liverworts (Bryophytes) widespread around the world. It belongs to the family Frullaniaceae Lorch., with a large number of species distributed into several subgenera, sections and subsections according with different morphological classifications.

Frullania pinnata spec. nov. (Frullaniaceae, Porellales), a new leafy liverwort in mid-Cretaceous Burmese amber from Myanmar

open access: yesCretaceous Research, 2017
An inclusion in Cretaceous amber from Myanmar is described as a new fossil species in the extant liverwort genus Frullania. The name Frullania pinnata is proposed for the taxon that is characterized by entire underleaves paired with a conspicuous pinnate branching pattern, two distinctive and stable morphological features.

Formalizing morphologically cryptic biological entities: New insights from DNA taxonomy, hybridization, and biogeography in the leafy liverwort Porella platyphylla (Jungermanniopsida, Porellales)

open access: yesAmerican Journal of Botany, 2011
• Premise of the study: Recognition and formalization of morphologically cryptic species is a major challenge to modern taxonomy. An extreme example in this regard is the Holarctic Porella platyphylla s.l. (P. platyphylla plus P. platyphylloidea). Earlier studies demonstrated the presence of three isozyme groups and two molecular lineages.

Divergence time analyses suggest a Miocene origin of the narrow Amazonian endemic rheophytic Ceratolejeunea temnantha (Spruce) Reiner-Drehwald (Porellales, Lejeuneaceae)

open access: yesBryophyte Diversity and Evolution, 2018
The recent rediscovery of the rheophytic endemic Ceratolejeunea temnantha ~130 years after its original description, on the upper Rio Negro in the Brazilian Amazon, has enabled the assessment of its enigmatic phylogenetic position, estimates of its divergence time, and updates on its distribution and potential habitat threats.

One species or at least eight? Delimitation and distribution of Frullania tamarisci (L.) Dumort. s. l. (Jungermanniopsida, Porellales) inferred from nuclear and chloroplast DNA markers

open access: yesMolecular Phylogenetics and Evolution, 2010
Frullania tamarisci is usually regarded as a polymorphic, holarctic-Asian liverwort species with four allopatric subspecies [subsp. asagrayana, moniliata, nisquallensis and tamarisci]. This hypothesis is examined using a dataset including sequences of the nuclear internal transcribed spacer region and the plastid trnL-trnF and atpB-rbcL regions of 88 ...
