Abstract Background Ferns, originated about 360 million years ago, are the sister group of seed plants. Despite remarkable progress in our understanding fern phylogeny, with conflicting molecular evidence and different morphological interpretations, relationships among major lineages remain controversial. Results With aim to obtain a robust we carried out large-scale phylogenomic analysis using high-quality transcriptome sequencing data, which covered 69 species from 38 families 11 orders....
Abstract The infrageneric relationships and taxonomy of the largest fern genus, Asplenium (Aspleniaceae), have remained poorly understood. Previous studies focused mainly on specific species complexes involving a few or dozens only, achieved large taxon sampling but only one plastid marker was used. In present study, DNA sequences from six markers ( atpB , rbcL rps4 ‐ trnS trnL trnL‐F ) 1030 accessions (616 them newly sequenced here) representing c . 420 (60% estimated diversity), 16...
Abstract Since the inception of genetic investigations into origin Dryopteris species belonging to D. subg. Erythrovariae in East Asia, around 20 taxa with hybrid ancestry have been identified. Among these species, some arisen from distant interspecific hybridization events. In this study, we describe and illustrate two newly discovered hybrids China: parabissetiana sp. nov., a triploid ×tiantangzhaiensis nothosp. diploid within Dryopteridaceae. Morphologically, exhibits similarities...
Abstract Ferns that evolved from 400 million years ago show various functional traits and ecological strategies in extant species, over 80% of which belong to the youngest order Polypodiales. How ferns have changed during their evolutionary history remains unexplored. Here, we measured are sensitive environmental light water availability 345 fern species across phylogeny, reconstructed histories. We found ferns, mainly Polypodiales, developed diversified response forest environments....
Leptochilus scandens, a new microsoroid fern species of Polypodiaceae from southwestern Guangdong, South China, is described and illustrated. The similar to some taxa the L. ellipticus complex in its frond shape lobe size, but differs them by climbing habit, monomorphic frond, fewer lobes, precocious individuals sometimes with simple or 2- 3-lobed fertile fronds.
Because synonymy treatment traditionally relies on morphological judgments, it usually causes many problems in species delimitation and the biodiversity catalogue. For example, Diplopterygium simulans, which belongs to Gleicheniaceae family, has been considered be synonymous with D. glaucum or giganteum based mainly morphology of its pinna rachis blade. In absence molecular evidence, these revisions remain doubtful. DNA barcoding, is a powerful method for species-level identification, was...
Abstract The taxonomy of the cliff fern family Woodsiaceae has been controversial with 22–59 species in 1–7 genera recognized various classifications. This is mainly due to limited taxon sampling (up 33 accessions representing up 21 species) and poor resolution molecular studies so far. In present study, DNA sequences five plastid markers ( atpA , matK, rbcL, rps4 + rps4‐trnS, trnL trnL‐F ) 152 ca. 43 out 65 estimated (122 accessions), 30 non‐Woodsiaceae from most closely related four...
Selaginella subg. Heterostachys, especially S. sect. Heterostachys and Tetragonostachyae, represents the most taxonomically difficult subgenus of in China. Here, austro-orientalis, a new species from Southeast China is described illustrated based on morphological phylogenetic studies. Morphologically, similar to heterostachys, but differs by its broadly ovate ventral leaves with slightly cuspidate apex strobili megasporangia only at side.
We describe a new species of Cyrtomium, C. calcis, from northern Vietnam and southern China, report records six in two fern genera, Arachniodes Polystichum, Dryopteridaceae, i.e., amabilis (from Lamdong Province), A. amoena (Quangtri fengii (Nghean globisora (Thanhhoa, Quangtri, Laocai provinces), nigrossora (Vinhphuc Polystichum ariticulatipilosum (Hagiang Province). The Cyrtomium most closely resembles pachyphyllum, but can be distinguished the latter shape petiole scales, number lateral...
Cyrtomium remotipinnum, a new species of Dryopteridaceae from the karst areas in Guangxi, China, is described and illustrated. The distinguished two most similar species, C. calcis pachyphyllum, by its larger stature higher length-to-width ratio pinnae. classified as Critically Endangered (CR) following IUCN Red List Criteria. In addition, this study attempted to identify some easily confused combining venation patterns soral distributions with other characters.
Based on field observations and examinations of herbarium specimens (including type material), consulting the original literature molecular phylogenetic analysis rbcL trnL-F sequences, it is concluded that Hypolepis robusta conspecific with alpina here formally treated as a synonym it. Additionally H. reported new distribution records in Guangdong, Guangxi Hainan Island China, respectively.
Selliguea quinquefida (Polypodiaceae), a new calciphilous species from Guangxi, China, is described and illustrated. The the second within genus with simple palmate fronds unique in having laminae cordiform bases. It grows peculiar habitat its rhizome creeping deeply hardened chalky soils on limestone under relatively dry conditions always bears palmately 5-lobed pentagonal shape when fully developed. differences habitats among S. all other are discussed.
Leptochilus tridigitatus, a new microsoroid fern species of Polypodiaceae from southwestern Guangdong, China, is described and illustrated. The morphologically highly variable most similar to L. poilanei in dimorphic fronds simple or trifid laminae, while its fertile are some those digitatus. can best be distinguished digitatus but sometimes confused with scandens due occasionally pinnatifid laminae two pairs lateral lobes. It might have been collected South China misidentified as other species.
The Indo-Burma Biodiversity Hotspot is renowned for its rich biodiversity, including that of vascular plants. However, the fern diversity and endemism in this hotspot have not been well understood so far, very few groups ferns region has explored using combined molecular morphological approaches. Here, we updated plastid phylogeny Java genus Leptochilus with 226 (115% increase latest sampling) samples across distribution range, specifically those three phylogenetically significant species,...
A new natural hybrid fern, Dryopteris × subdiffracta (Dryopteridaceae), is reported from Guangxi, China. Molecular phylogenetic analysis based on DNA sequences the low-copy nuclear marker Ak1 and plastid genome revealed respectively that D. polita diffracta are parents of hybrid, with as maternal parent. Cytometric content indicated might be a diploid hybrid. Morphologically, shares high degree similarity subreflexipinna Taiwan, especially in zigzag-shaped rachis deflexed pinna stalks....
