We carried out a molecular phylogenetic analysis of Neotropical lady ferns (Athyrium s.str. and Anisocampium) using five plastid markers. We found two major results. First, three Neotropical species (Anisocampium skinneri, Athyrium palmense, A. tejeroi) formed a clade, and this clade was sister to the rest of Athyrium. The three members of this clade differ from Athyrium s.l. by creeping rhizomes with internodes 1–2 mm long, and rhizome apices that protrude beyond the current season's cluster of leaves. Also, the leaves are distichously arranged, lack trophopods, have petiole bases broadly U‐shaped in transverse section, and bear thin, membranous laminae. We recognize this clade as a new genus, Ephemeropteris, and provide three new combinations: E. palmensis, E. skinneri, and E. tejeroi. The name of the new genus is derived from the seasonal production of its leaves, which are produced during the wet season and die back (i.e., are ephemeral) at the beginning of the dry season. Ephemeropteris is largely restricted to the Pacific side of Central America, a region that exhibits a marked dry season from November to May. We provide a key to the seven genera (including Ephemeropteris) we now recognize in the Athyriaceae, and a taxonomic treatment of the three species of Ephemeropteris. The treatment includes descriptions, illustrations, nomenclatural data, specimens cited, and a dot‐distribution map. Our second major result from the phylogenetic analysis is that the remaining three Neotropical species of Athyrium s.str. are polyphyletic. One of our seven samples was resolved in the A. filix‐femina clade (sect. Athyrium), to which all species of Neotropical Athyrium were previously assumed to belong to. Our six other samples of Neotropical Athyrium were resolved in A. sect. Mackinnoniana, previously construed as entirely Asian.

“…We also evaluated the phylogenetic and geographic distribution of polyploid species to assess if polyploidization is related to range evolution or ecological shifts because of increased ecological tolerances, as hypothesized in other plant groups (e.g., Kuo et al, 2016;Marchant, Soltis, & Soltis, 2016;Sessa, Testo, & Watkins, 2016). In addition, we sought to reconstruct the ancestral ranges for each of the five major clades within Sphagnum.…”

Peat mosses (Sphagnum) hold exceptional importance in the control of global carbon fluxes and climate because of the vast stores of carbon bound up in partially decomposed biomass (peat). This study tests the hypothesis that the early diversification of Sphagnum was in the Northern Hemisphere, with subsequent range expansions to tropical latitudes and the Southern Hemisphere. A phylogenetic analysis of 192 accessions representing the moss class Sphagnopsida based on four plastid loci was conducted in conjunction with biogeographic analyses using BioGeoBEARS to investigate the tempo and mode of geographic range evolution. Analyses support the hypothesis that the major intrageneric clades of peat‐forming species accounting for >90% of peat moss diversity originated and diversified at northern latitudes. The genus underwent multiple range expansions into tropical and Southern Hemisphere regions. Range evolution in peat mosses was most common within latitudinal zones, attesting to the relative difficulty of successfully invading new climate zones. Allopolyploidy in Sphagnum (inferred from microsatellite heterozygosity) does not appear to be biased with regard to geographic region nor intrageneric clade. The inference that Sphagnum diversified in cool‐or cold‐climate regions and repeatedly expanded its range into tropical regions makes the genus an excellent model for studying morphological, physiological, and genomic traits associated with adaptation to warming climates.
