1001 Dryopteris Adans.
- Adans., Fam. Pl. 2: 20, 551 (1763) nom. cons..
- Excluded: Dryopteris abbreviata, D. dilatata.
Notes: The five species that reach the Arctic belong to three different groups, all nearly circumboreal: (a) the D. dilatata group with D. carthusiana and D. expansa as representatives reaching the Arctic; (b) the D. filix-mas group with D. filix-mas and D. marginalis as such; and (c) D. fragrans. The first-mentioned group is problematic and has been extensively investigated (see references in Montgomery and Wagner Jr. 1993 and Sarvela 2000b). Six species names have been applied to three northern species - D. dilatata (= D. austriaca auct.), D. carthusiana (= D. spinulosa), and D. expansa (= D. assimilis) - only the two last-mentioned species have documented arctic occurrences. Northwestern European authors have often confused the more temperate D. dilatata with D. expansa, whereas Russian authors have confused D. carthusiana and D. expansa.
