Abstract:
... The fern genus Lepisorus represents one of the most complicated and controversial lineages in Polypodiaceae, with about 80 species which have been classified into several separate genera, and is notorious for its taxonomic difficulty. Despite progress in recent phylogenetic studies of the family Polypodiaceae involving Lepisorus and its allies, the deep phylogenetic relationship within this group ...

The hybrid, most of whose spores are aborted, shows intermediate morphology between its putative parents (J. biardii and J. insignis) in lamina dissection, shape of the ultimate segments, and pubescence of the adaxial surface of the pinnae and rachises. ...

Abstract:
... Women have long been underrepresented in STEM, although there are certain fields within this umbrella that show less of a disparity — the biological sciences being one example. Within biology, pteridology has a rich history of female contributors involved since its inception. In this review we strive to highlight some of the foremost female pteridologists including Elizabeth Knight Britton, Alma S ...

Abstract:
... Peptidoglycan has been retained in chloroplasts that have evolved from cyanobacteria along some evolutionary tracks, but has seemingly been quickly eliminated during evolution of others. It has been eliminated in Rhodophyta, Chlorophyta, Pteridophyta and Spermatophyta, but has been retained in streptophyte algae, Glaukophyta, and Lycophyta. In this article questions emerging from this are raised, ...

Abstract:
... While polyploidization is recognized as a major evolutionary driver for ferns and angiosperms, little is known about its impact in gymnosperms, where polyploidy is much less frequent. We explore Ephedra to evaluate (i) the extent of genome size diversity in the genus and the influence polyploidy has had on the evolution of nuclear DNA contents, and (ii) identify where shifts in genome size and pol ...

In this study, we present a global phylogeny of Stegnogramma s.l. with the most ...

Abstract:
... The hybrid Polystichum × arendsii was first bred by Georg Arends at the turn of the 20th century. It was an artificial cross between P. munitum (Kaulf.) C.

Christ applied the name Aspidium × arendsii to this hybrid. In the following decades the ...

Abstract:
... The infrageneric relationships and taxonomy of the largest fern genus, Asplenium (Aspleniaceae), have remained poorly understood. Previous studies have focused mainly on specific species complexes involving a few or dozens of species only, or have achieved a large taxon sampling but only one plastid marker was used. In the present study, DNA sequences from six plastid markers (atpB, rbcL, rps4, rp ...

Abstract:
... The microsoroid ferns are one of the largest subfamilies of the Polypodiaceae with over 180 species mainly found in the humid forests of tropical Australasia. The phylogenetic relationships are still unclear, especially the delimitation of the genus Microsorum which has been recognized to be non-monophyletic. We analysed the microsoroid ferns using six chloroplast DNA regions (rbcL, rps4+rps4-trnS ...

For this study, we opted for a simple random sampling method, using the phytoecological method for the study of the flora. A statistical analysis of field data was processed by ADE.4, an analysis that highligh ...

On the basis of an investigation into epiphytic ferns and taking into account the literature data, information on ecological classifications of vascular epiphytes has been summarized and a multiple ecological classification is proposed in which vascular epiphytes are grouped into three blocks of morphofunctional types (MFT): facultative epiphytes (protoepiphytes), obligate epiphytes (holoepiphytes ...

Abstract:
... BACKGROUND: Hydraulically efficient xylem was evolved in the vascular plants as an apomorphy of the group. Main xylem components involved in water conduction are tracheid and vessel. Vessels, in which two ends are perforated, constituted major evolutionary innovation within vascular plants, presumably providing more efficient solute conduction. Not all vascular plants have vessels. In pteridophyte ...
