... Additionally, the proportion of sampled taxa in each clade was supplied using the sampleProbsFilename argument for the control files to account for incomplete taxon sampling (Supplemental Material Table S2). This sampling data allowed us to account for incomplete taxon representation at the genus level, based on the most recent hornworts and liverworts checklist provided by Söderström et al. (2016). Including these data has been shown to reduce the effect of incomplete taxa on the estimates of diversification rates (Rabosky 2018;Sun et al. 2020). ...
... Similarly, Laenen et al. (2014) sampled only one species from each genus within Aneuraceae. Both studies were conducted before the updated checklist of Söderström et al. (2016), which significantly increased the number of recognised Aneuraceae species. By contrast, our study included denser taxon sampling, using three chloroplast regions from Aneuraceae, thus providing a more comprehensive dataset than previous studies. ...
Introduction. Aneuraceae, the largest family of simple thalloid liverworts, is recognised for its unique ecology and cryptic diversity despite its simple morphological features. In the present study, we explored the evolutionary history and diversification of Aneuraceae, focusing on the efects of fossil calibrations on divergence time estimates and the significance of including cryptic species in macroevolutionary analyses. Methods. We used publicly available nucleotide sequences to reconstruct chronograms of Aneuraceae, incorporating other representatives from subclass Metzgeriidae as outgroups. We also assessed the efects of various calibration approaches on chronogram reconstruction. The resulting time-calibrated phylogeny was subjected to time plots, m-statistics, and Bayesian analysis of macroevolutionary mixtures (BAMM) to uncover diversification dynamics within the Aneuraceae lineage. Key results. Aneuraceae originated and diversified from the Upper Devonian (358.04 Mya, 95% highest posterior density: 513.61-268.36) to the Lower Carboniferous period. Our analysis revealed late bursts of diversification, with significant rate shifts at the crown node of the genus Riccardia and at the Neotropical clade within Riccardia. Including cryptic taxa in the analyses introduced an additional rate shift at the crown node of the genus Aneura. Conclusions. Aneuraceae probably originated during the middle Paleozoic, like other early terrestrial plants, although diferent fossil-calibration approaches significantly inwuenced the divergence time estimates. The speciation rate shifts in Riccardia could be attributed to asexual reproduction within this genus, as well as climate changes and geological events in the Neotropics. Ecological conditions at the origin of Aneuraceae may have played a role in driving its increased diversification.

Aim
Considering the importance of microclimate in maintaining the diversity of epiphytic bryophytes, we investigated epiphytic bryophytes along an elevational gradient in the subtropical forest of eastern China to unravel the diversity patterns of epiphytic liverworts and mosses along the elevational gradients and the roles of forest microclimates, topographic variables and host plant composition attributes in shaping these elevational diversity patterns.
Location
Tianmushan National Nature Reserve, Zhejiang, China.
Taxon
Epiphytic bryophytes.
Methods
Species diversity patterns of liverworts and mosses were compared based on an inventory of 16 plots along an elevational gradient from 367 to 1470 m. In situ microclimatic data of air temperature and moisture were collected under constant monitoring for over 3 years. Spatial linear models and structural equation models were used to assess the relative roles of the environmental variables in shaping the patterns of species diversity along elevation.
Results
We found that epiphytic liverwort and moss richness showed different elevational patterns; overall richness patterns of epiphytic bryophytes were largely driven by mosses. Epiphytic mosses exhibited a decline, followed by a hump‐shaped pattern of species richness with increasing elevation, while epiphytic liverworts showed a mid‐elevation plateau with a richness maximum between 800 and 1300 m. Forest microclimate, topography and host plant composition attributes influence epiphytic moss and liverwort patterns differently and interact in a complex way. Overall, species richness of epiphytic liverworts was most strongly affected by microclimate (mean annual air temperature of growing season) and of epiphytic mosses richness by topography (slope). Further, epiphytic liverwort species richness was more influenced by temperature than moisture.
Main Conclusions
This study highlights the importance of collecting climatic factors at a fine scale (microhabitats) for understanding the patterns and drivers of bryophyte diversity. Further, our findings demonstrate the differences between liverworts and mosses in terms of their response to different environments in the forest ecosystem.
... After examining the specimens preserved at the Herbarium of the East China Normal University (HSNU), including a high proportion of our recent collections, we obtained the following collection information for each species: year of collection, collector, locality, altitude, and type of substratum. We standardized the nomenclature according to Söderström et al. (2016) and Jia and He (2013). A total of 9753 records belonging to 638 species of 217 genera in 78 families were included in this study. ...
Knowing the total number of species in a region has been a question of great interest motivated by the need to provide a reference point for current and future losses of biodiversity. Unfortunately, obtaining an accurate number is constrained by the fact that most species remain to be discovered, due to the imperfect detection of species in the field collection or because of temporal turnover in species composition. Here, to understand the inventory completeness at the local scale, we studied the temporal dynamics in the species richness and composition of bryophytes in Tianmushan National Nature Reserve. We used β‐diversity to measure the temporal variation and analyzed the species attributes of newly discovered species collected this time. Furthermore, we evaluated our sampling strategy to measure sampling effect and estimated the species that remain to be discovered. We found that total β‐diversity was largely driven by turnover. The analysis of species attributes showed that epiphytic species dominate the newly recorded species in both the narrow and wide elevational range species. Further, if only one of the methods was adopted, 26%–29% of the newly discovered species would be missed, and we inferred that there are likely are 185 bryophytes yet to be discovered. Our results indicate that when the same effort was made, an appropriate sampling methodology is crucial to accelerate newly recorded species discovery. Further, the results of our study highlight that species temporal turnover should be considered when assessing the completeness of species inventories at the local scale.
... Lüth (2019) shows differences in the pseudoparaphyllia: narrow and filamentous in H. andoi; wide and foliose in H. uncinulatum. No such distinction is made by Smith (2004) or Guerra & Brugués (2018), and the distinction is not supported in examination of the specimens used in this study, with the pseudoparaphyllia variable across both haplotypes. ...
... This low taxonomic value placed on the sporophyte is interesting, because sporophytic characters have been used extensively in the past for identifying H. uncinulatum (e.g. Smith, 2004). However, the results of this study, which link the molecular data with the morphology of the gametophyte, tend to support the views in Flora Briofítica Ibérica. ...
... S. subellipticum tends to be smaller, with less highly coloured rhizoids and growing in more base-rich habitats, but is otherwise almost indistinguishable from S. obovatum. However, it was nested within Solenostoma obovatum in a molecular study by Shaw et al. (2015) and thus reduced to a synonym, a treatment followed by Söderström et al. (2016). It was, however, included in the European checklist (Hodgetts et al., 2020), albeit with some hesitation and disagreement. ...

Anthocerotophyta is a distinct group among bryophytes. The members of this group show characteristic similarity with Algae in having a single chloroplast with pyrenoid bodies, as well as thallose gametophytes like liverworts. They are unique among bryophytes in having a horn-like sporophyte with unlimited growth. The majority of members can fix atmospheric nitrogen by having Nostoc colonies embedded in their gametophytes. They also provide microhabitat to other small insects which is beneficial to the ecosystem. In India, they are represented by 7 genera viz., Anthoceros, Folioceros, Notothylas, Phaeoceros, Megaceros and a recently discovered genus Phymatoceros. The members of genus Folioceros mostly distributed in the tropical and subtropical regions of East and South-East Asia. Folioceros amboinensis (Schiffn.) Piippo [Anthocerotaceae; Anthocerotophyta], a very little-known species, earlier reported from Andaman & Nicobar Islands and Kerala in India, is reported and described here as a new distributional record from Mizoram, Eastern Himalayan Bryo-geographical territory. A detailed description, colour photo plate and SEM of sporoderm are provided.

These plants play important roles in water conservation, plant colonization, seed germination, seedling growth, and forest regeneration [7]. ...
Specimen data play a crucial role in geographical distribution research. In this study, the collection information of liverwort specimens in China was compiled and analyzed to investigate the history, current status, and limitations of liverwort research in China. By utilizing the latest systematic research findings and corresponding environmental data, a niche model was developed to offer theoretical support for exploring the potential geographical distribution and diversity of liverwort resources. A total of 55,427 liverwort specimens were collected in China, resulting in the recording of 1212 species belonging to 169 genera and 63 families. However, there are imbalances in the distributions of liverwort data among different groups, collection units, and geographical areas, with families such as Lejeuneaceae, Porellaceae, and Plagiochilaceae having the highest number of specimens. Similarly, genera such as Porella, Frullania, and Horikawaella were well represented. Remarkably, 125 species had specimen counts exceeding 100. Unfortunately, approximately 51.77% of the species had fewer than 10 recorded specimens. There were four obvious peaks in the collection years of the bryophyte specimens in China, among which the largest collection occurred from 2010 to 2023. Notably, the number of specimens collected at different stages closely aligned with the history of taxonomic research on liverworts in China. The results of the integrity of the liverwort collection indicate that there is insufficient representation of some families and genera, with a concentration of common and widely distributed large families and genera. Tropical and subtropical humid areas are key regions for liverwort diversity, with water and temperature being the primary environmental factors influencing their geographical distribution. The specific temporal and spatial data of species recorded from plant specimens will enhance the study of species diversity, comprehensive protection, and sustainable utilization. Additionally, these data will contribute to the investigation of large-scale biodiversity distribution patterns and the impact of global change on diversity.
... Both F. pentapleura and F. proboscifora are considered to belong to F. sect. Australes in Söderström et al.

Frullania (subg. Trachycolea) sect. Trachycolea has been studied using integrative taxonomy methods and utilizing sampling from almost all areas of distribution of the species previously referred to this section. A phylogenetic analysis based on nuclear ribosomal ITS1-2 and chloroplast trnL-F sequence data and a morphological study reveal a wide range of morphological variability within specimens that has largely disguised the overall taxonomic diversity. Frullania parvistipula, previously regarded as a widespread species, has been found to represent a group of separate species within different sections of F. subg. Trachycolea: F. caucasica and F. conistipula in F. sect. Trachycolea, F. parvistipula in F. sect. Australes, and F. fukuzawana in F. sect. Integristipulae II. Illustrations of the type specimens of F. conistipula, F. fukuzawana, and F. parvistipula, as well as illustrations of the sequenced specimens belonging to two of the discussed species (F. conistipula and F. parvistipula), are provided. The morphological differences separating the highly similar F. caucasica, F. conistipula, F. fukuzawana, F. koponenii, and F. parvistipula are discussed. A dichotomous key is presented for accepted species. New combinations are provided for two taxa.
... Lepidoziaceae is one of the most speciose families of liverworts, with approximately 440 accepted species according to Frey and Stech (2009). The status of many described taxa is still questionable (Söderström et al., 2016) as well as the division into seven subfamilies with 29 genera outlined by Frey and Stech (2009) probably needs clarification. In the north of the Holarctic (= Holarctic northwards of the subtropics), the number of known Lepidoziaceae is quite low in the boreal forest zone and further north. ...
... Frey and Stech (2009) estimate the total diversity of the genus to be approximately 30 species. Söderström et al. (2016) provide a list of 49 species, of which the infrageneric position (to which sections they are belonging) is known for only 13 species, and another 36, including K. makinoana (Steph.) Grolle, known in the Far East, are assigned to the group Incertae sedis. ...
... Frey and Stech (2009) estimate the total diversity of the genus as approximately 60 species. Söderström et al. (2016) list 147 species, many of which are of unclear status (marked by 1-2 stars on the list). In the regions adjacent to the Russian Far East a few species are known. ...
Kurzia and Lepidozia are revised for the Russian Far East. The identification keys, morphological descriptions, line drawings and lifetime photographs of species, ecological conditions and the clarified distribution within the region are provided. In general, the Russian Far East seems too cold region for high taxonomic diversity of the members of the family; nevertheless, the taxonomic diversity of Lepidoziaceae here is higher than in other regions of Russia.
