  1. Numbers after species names indicate that multiple accessions of that species were included. Collection locations are given, and inclusion in plastid, pgiC, gapCp, and PADRE datasets is indicated. AFSSE and BPSSE indicate species that were obtained as spores from the American Fern Society Spore Exchange and British Pteridological Society Spore Exchange, respectively. These spores were germinated and grown for use by Geiger and Ranker [64], and DNA material later provided to us. Number of copies of gapCp and pgiC are given in parentheses if we successfully sequenced that region for an accession. Ploidy level is given when known, with references. See Additional file 1: Table S1 for voucher information.
  2. * The pgiC sequence for D. ludoviciana A208 was obtained from Genbank, and we included it in the current study as it was the basis for a recent rejection of the “semicristata” hypothesis [49].
  3. ** We were unable to sequence pgiC from our D. affinis and D. oreades accessions, and so obtained pgiC sequences for these taxa from Genbank. These sequences are therefore not from the same accessions as the gapCp and plastid sequences.
  4. a synonymous with D. expansa.
  5. b synonymous with D. dilatata.
