TL;DR: A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.

TL;DR: A comprehensive analysis of Podocarpaceae at the species level using molecular data, biogeography, anatomy, and morphology has not been previously attempted as discussed by the authors, however, this analysis was performed using nrITS1 and NEEDLY intron 2 for two-thirds (183 accessions of 145 taxa).

TL;DR: A first identification key for the entire Cypress family (Cupressaceae) could be set up which comprises any of the 30 genera, 134 species, 7 subspecies, 38 varieties, one form and thus all 180 taxa recognized by Farjon (2001).

TL;DR: Comparative analyses of sequence quality and species discrimination were conducted on the 159 individuals from which all three markers were recovered, finding that the vast majority of sequences were of high quality and even the lowest quality sequences exceeded the minimum requirements of the BARCODE data standard.

TL;DR: Selaginella originated on Euramerica around 383 Ma in the Devonian period, while its peak diversification began with the formation of Pangea, and node density analyses revealed that Selaginellaceae has significantly older median and mean node ages than other putative “ancient” families.
