“…Though modern lycophyte diversity and ecological prominence pales in comparison to that of their Palaeozoic relatives, and they are today overshadowed by seed plants and ferns, understanding the evolutionary history of the group is important because it provides insight into the timing and patterns of early land plant diversification. Recent studies have examined the divergence timing and historical biogeography of the Isoetaceae (Pereira, Labiak, Stützel, & Schulz, ) and Selaginellaceae (Klaus, Schulz, Bauer, & Stützel, ; Weststrand, ); however, the only dated phylogeny of the Lycopodiaceae (Wikström & Kenrick, ) was published more than 15 years ago and did not include a biogeographical analysis.…”

“…From an ecological point of view, the group includes both amphibian and aquatic species. A few taxa hitherto studied in molecular phylogenetics show close evolutionary relationships (Larsén & Rydin, 2016;Pereira & al., 2017), but most of the taxa here listed have still to be included in such analyses. Most species that have been studied karyologically (I. asturicensis, I. longissima subsp.…”

“…Isoetes longissima is "amphibious", growing in temporary (seasonal) pools and spends some (summer) months dormant and without leaves. These species share the presence of phyllopodia (black, indurate remains of dead leaves encircling the leaf rosette at its base) and similar habitats (usually seasonally wet or flooded soils); the taxa hitherto analysed in molecular phylogenetics (Larsén & Rydin, 2016;Pereira & al., 2017) showed conflicting results (two accessions of I. histrix were retrieved in two nonclosely related clades, probably due to misidentifications - Larsén & Rydin, 2016) and/or inaccurate morphological delimitation of the taxa. Caryological data suggest 2n = 20 for I. histrix and 2n = 22 for I. gymnocarpa (Troia & al., 2016), but some recent counts suggesting distinction of another taxon similar to I. gymnocarpa with 2n = 20 (Bagella & al., 2015) leaves cytological and taxonomic relationships unresolved amongst these taxa.…”

“…While the initial diversification of the lycophytes occurred during the Devonian and Carboniferous (Kenrick & Crane, 1997;Morris et al, 2018), much of their extant diversity has been suggested to have originated considerably later. Apart from the early divergences in the Lycopodiopsida in the Late Triassic, most extant lineages are supposed to have diversified during the Cretaceous (Klaus et al, 2017;Pereira et al, 2017;Testo et al, 2018), coinciding with the rise of modern fern and angiosperm lineages (Schneider et al, 2004;Schuettpelz & Pryer, 2009;Barba-Montoya et al, 2018;Morris et al, 2018).…”
