Resolving the overall pattern of marattialean fern phylogeny
Abstract: Marattiales is a monophyletic group that is extremely common in late Paleozoic and early Mesozoic deposits, with a stem group Psaroniaceae and a crown group Marattiaceae. Because Marattiaceae represents only a small component of overall marattialean diversity, living species alone neither account for evolutionary changes within the clade over time, nor accurately reflect the overall pattern of marattialean fern phylogeny.

“…However, in Danaeopsis the sporangia are arranged in two rows covering the entire lower lamina and are not fused into a synangia as in extant forms (Kustatscher et al, 2012). This topology is somewhat comparable with the results of Rothwell et al (2018), who resolved these genera nested within the Marattiaceae. Apparently Qasimia never survived the Permian mass extinction, but Danaeopsis became an important component of the Triassic floras (Kustatscher et al, 2012).…”

“…Because the resolution within Psaroniaceae remained highly unstable, the relationships within this family are not discussed further. We note, however, that Gemellitheca Wagner et al and Buritiranopteris Tavares et al generally were resolved as early radiations and often as sisters, thus supporting similar resolutions for these taxa by Rothwell et al (2018), and that we generally recovered monophyletic Scolecopteris .…”

“…This genus remained somewhat unstable in our analyses. Unlike Murdock (2008b) or Rothwell et al (2018), we found that the most plausible phylogenetic position for Christensenia is a sister relationship with Marattia . An alternative position, supported by the plastome data under parsimony and phenotypic evidence, resolved Christensenia as a distinct lineage splitting off after Danaea had been separated from the rest of the Marattiaceae.…”

“…Topologically, our results for extant relationships are generally consistent with other molecular studies of Marattiales phylogeny, including in supporting Danaea as sister to the rest of the extant marattialeans ( Murdock 2008b ; Lehtonen et al 2020 ), and supporting the monophyly of each genus ( Murdock 2008b ; Rothwell et al 2018b ; Lehtonen et al 2020 ). Among the extant taxa, the main point of uncertainty remains the position of Christensenia .…”
